Gratitude enhances health, brings happiness — and may even lengthen lives

Several evenings a week, as Tyler VanderWeele gathers around the dinner table with his wife and two young kids, the family deliberately pauses during the meal to do something simple but profound. Each member shares several things for which they’re grateful — an act that VanderWeele, co-director of the Initiative on Health, Spirituality, and Religion at the Harvard T.H. Chan School of Public Health, feels changes his family dynamic for the better.

“I do think it makes a difference and can be a very powerful practice,” he says. “Even on those bad days where life seems difficult, that effort is worthwhile.”

Gratitude, health, and longevity

How can the power of gratitude affect our lives? Recent research has pointed to gratitude’s myriad positive health effects, including greater emotional and social well-being, better sleep quality, lower depression risks, and favorable markers of cardiovascular health. Now, new data from the long-term Nurses’ Health Study shows that it may extend lives.

“Gratitude has been one of the most widely studied activities contributing to well-being, but we couldn’t find a single prior study that looked at its effects on mortality and longevity, much to our surprise,” says VanderWeele, co-author of the new research.

What did the study look at?

Published July 2024 in JAMA Psychiatry, the new study drew on data from 49,275 women enrolled in the Nurses’ Health Study. Their average age was 79. In 2016, participants completed a six-item gratitude questionnaire in which they ranked their agreement with statements such as, “I have so much in life to be thankful for,” and “If I had to list everything I felt grateful for, it would be a very long list.”

Four years later, researchers combed through participants’ medical records to determine who had died. There were 4,608 deaths from all causes, as well as from specific causes such as cardiovascular disease, cancer, respiratory diseases, neurodegenerative disease, infection, and injury. Deaths from cardiovascular disease — a top killer of women and men in the United States — were the most common cause.

What did the researchers find?

Participants with gratitude scores in the highest third at the study’s start had a 9% lower risk of dying over the following four years than participants who scored in the bottom third. This did not change after controlling for physical health, economic circumstances, and other aspects of mental health and well-being. Gratitude seemed to help protect participants from every cause of death studied — including cardiovascular disease.

But what does this actually mean?

“A 9% reduction in mortality risk is meaningful, but not huge,” VanderWeele says. “But what’s remarkable about gratitude is that just about anyone can practice it. Anyone can recognize what’s around them and express thanks to others for what’s good in their life.”

While the study couldn’t pinpoint why gratitude is associated with longer life, VanderWeele believes several factors may contribute.

“We know that gratitude makes people feel happier. That in itself has a small effect on mortality risk,” he says. “Practicing gratitude may also make someone a bit more motivated to take care of their health. Maybe they’re more likely to show up for medical appointments or exercise. It may also help with relationships and social support, which we know contribute to health.”

What are the study’s limitations and strengths?

The study was observational. This means it can’t prove that gratitude helps people live longer — only that an association exists. And the particular sample of people analyzed is both the biggest strength and limitation of the research, VanderWeele says. All were older female nurses with high socioeconomic status. The vast majority were white.

“Does the longevity effect extend to men, to those who are younger, and to those with lower socioeconomic resources?” VanderWeele asks. “Those are all open questions.”

On the plus side, he says, the study sample’s large size is one of its biggest strengths. So is the extensive data gathered on potential confounding factors such as participants’ physical health, social characteristics, and other aspects of psychological well-being.

“Between the quality of the data and the size of the sample, we were able to provide reasonable evidence for this modest longevity effect,” he says.

Try this: Six questions to evoke gratitude

Not feeling especially grateful today? You have the power to change that. Asking yourself certain questions can evoke gratitude, such as

  • What happened today that was good?
  • What am I taking for granted that I can be thankful for?
  • Which people in my life am I grateful for?
  • What is the last book I read or movie, show, or social media clip I saw that I really appreciated, and why?
  • What am I most looking forward to this week, month, and year, and why?
  • What is the kindest thing someone has said or done lately?

Similarly, a few simple actions can infuse gratitude into your days. Try VanderWeele’s family routine of regularly expressing gratitude around the dinner table. Another well-known practice — that’s perhaps becoming forgotten in this digital age — is penning thank-you notes.

“I do think writing a thank-you note or gratitude letter gets your mind to dwell on something positive for a longer period, to think more deeply about it, because you have to put it not just in words, but in writing,” VanderWeele says. “It also deepens the relationship and builds that bond.”

One less-recognized but valuable gratitude practice is called a “savoring exercise,” which builds on aspects of mindfulness. All that’s required is “pausing, looking around you, and taking in and enjoying everything that’s good in your current setting,” VanderWeele says. “It’s not a big leap to go from recognizing the good to expressing gratitude for what you have.”

Helping children make friends: What parents can do

Three children around three large, interlocked white puzzle pieces and a fourth bringing a large piece to finish the puzzle; background is gray

We all want our child to have friends. We want them to be happy, and to build the social skills and connections that will help them now and in the future.

Sometimes, and for some children, making friends isn’t easy. This is particularly true after the COVID-19 pandemic. Because of isolation and remote school, many children either didn’t learn the skills they need to make friends — or those skills got rusty.

Here are some ways parents can help.

Start at home: Learning relationship skills

Making and keeping friends involves skills that are best learned at home with your family. Some of them include:

  • Empathy. Make sure that everyone in the family treats each other fairly and with kindness. Sometimes we turn a blind eye to sibling fights, or feel justified in snapping at our partner when we have had a long day. No matter what we say, our children pay attention to what we do.
  • Curiosity about others. Make a family habit of asking each other about their day, their interests, their thoughts.
  • Communication skills. These days, devices endanger the development of those skills. Shut off the devices. Have family dinners. Talk with each other.
  • Cooperation. Do projects, play games, and do chores as a family. Work together. Help your child learn about taking turns and valuing the input of others.
  • Regulating emotions. It’s normal to have strong feelings. When your child does, help them find ways to understand big emotions and manage them.
  • Knowing when and how to apologize — and forgive. This really comes under empathy, but teach your child how to apologize for their mistakes, make amends, and forgive the mistakes of others.

All of these apply also to how you and your partner talk about — or with — other people in front of your children, too!

Be a good role model outside the home, too

When you are outside your home, be friendly! Strike up conversations, ask questions of people around you. Help your child learn confidence and strategies for talking to people they don’t know.

Make interactions easier

Conversations and interactions can be easier if they are organized around a common interest or activity. Here are some ways parents can help:

  • Sign your child up for sports or other activities that involve their peers. Make sure it’s something they have at least some interest in doing.
  • Get to know the parents of some of your child’s peers — and invite them all to an outing or meal. It could allow the children to get to know each other while taking some of the pressure off.
  • When planning playdates, think about fun, cooperative activities — like baking cookies, or going to a park or museum.

Keep an eye on your child — but don’t hover

Ultimately, your child needs to learn to do this — and you don’t want to embarrass them, either. The two exceptions might be:

  • If the children aren’t interacting at all, you might want to suggest some options for activities. Facilitate as necessary, and step back out again.
  • If there is fighting or meanness on either side, you should step in and make it clear that such behavior isn’t okay.

Keep an open line of communication, and be supportive

Talk with your child regularly about their day, about their interactions, and how things made them feel. Listen more than you talk. Be positive and supportive. Remember that part of being supportive is understanding your child’s personality and seeing the world from their eyes. You can’t make your child someone they are not.

If your child keeps struggling with making friends, talk to your doctor

All parents need help sometimes — and sometimes there is more to the problem than meets the eye. This is particularly true if your child has ADHD or another diagnosis that could make interactions more challenging.

Are you getting health care you don’t need?

illustration in shades of green and white showing stylized medical objects: thermometer, bandage, medication bottle, stethoscope, syringe, clipboard, blister pack of pills

Ever wonder if every medical test or treatment you've taken was truly necessary? Or are you inclined to get every bit of health care you can? Maybe you feel good about getting the most out of your health insurance. Perhaps a neighborhood imaging center is advertising discounted screening tests, your employer offers health screens as a perk, or you're intrigued by ads touting supplements for a seemingly endless number of conditions.

But keep in mind: just because you could get a particular test or treatment or take a supplement doesn't mean you should. One study suggests that as much as 20% of all health care in the US is unneeded. In short: when it comes to health care, more is not always better.

Isn't it better to be proactive about your health?

We're all taught that knowledge is power. So it might seem reasonable to want to know as much as possible about how your body is working. And isn't it better to take action before there's a problem rather than waiting for one to develop? What's the harm of erring on the side of more rather than less?

The truth is that knowledge is not always power: if the information is irrelevant to your specific situation, redundant, or inaccurate, the knowledge gained through unnecessary health care can be unhelpful or even harmful. Unnecessary tests, treatments, and supplements come with risks, even when they seem harmless. And, of course, unnecessary care is not free — even if you're not paying a cent out of pocket, it drives up costs across health systems.

Screening tests, wellness strategies, and treatments to reconsider

Recommended screening tests, treatments, and supplements can be essential to good health. But when risks of harm outweigh benefits — or if proof of any benefit is lacking — think twice. Save your time, money, and effort for health care that is focused on the most important health threats and backed by evidence.

Cancer screening: When to stop?

Screening tests for some cancers are routinely recommended and can be lifesaving. But there's a reason they come with a recommended stop age. For instance, guidelines recommend that a person at average risk of colorectal cancer with previously normal colonoscopies stop having them once they turn 75. Similar limits apply to Pap smears (age 65) and mammograms (age 75). Studies suggest that beyond those ages, there is little benefit to continuing these screens.

Watch out for wellness marketing

Dietary supplements are a multibillion-dollar industry. And a whopping 70% or more of US adults take at least one, such as vitamin D, fish oil, or a multivitamin. People often consider them as insurance in case vital elements are missing from their diet, or they believe supplements can prevent dementia, heart disease, or another condition.

Yet little evidence supports a benefit of routine supplement use for everyone. While recent studies suggest a daily multivitamin might slow cognitive decline in older adults, there's no medical consensus that everyone should be taking a multivitamin. Fish oil (omega-3) supplements haven't proven to be as healthful as simply eating servings of fatty fish and other seafood low in toxic chemicals like mercury and PCBs. And the benefits of routinely taking vitamin D supplements remain unproven as well.

It's worth emphasizing that dietary supplements clearly provide significant benefit for some people, and may be recommended by your doctor accordingly. For example, if you have a vitamin or mineral deficiency or a condition like age-related macular degeneration, good evidence supports taking specific supplements.

Reconsider daily aspirin

Who should be taking low-dose aspirin regularly? Recommendations have changed in recent years, so this is worth revisiting with your health care team.

  • Older recommendations favored daily low-dose aspirin to help prevent cardiovascular disease, including first instances of heart attack and stroke.
  • New recommendations favor low-dose aspirin for people who've already experienced a heart attack, stroke, or other cardiovascular disease. Adults ages 40 to 59 who are at a high risk for these conditions and low risk for bleeding also may consider it.

Yet according to a recent study, nearly one-third of adults 60 and older without past cardiovascular disease take aspirin, despite evidence that it provides little benefit for those at average or low risk. Aspirin can cause stomach bleeding and raise risk for a certain type of stroke.

Weigh in on prostate cancer screening

Men hear about prostate cancer often. It's common, and the second leading cause of cancer deaths among men. But PSA blood tests and rectal exams to identify evidence of cancer in the prostate are no longer routinely recommended for men ages 55 to 69 by the United States Preventative Services Task Force.

The reason? Studies suggest that performing these tests does not reliably reduce suffering or prolong life. Nor do possible benefits offset downsides like false positives (test results that are abnormal despite the absence of cancer). That can lead to additional testing, some of which is invasive.

Current guidelines suggest making a shared decision with your doctor about whether to have PSA testing after reviewing the pros and cons. For men over age 70, no screening is recommended. Despite this, millions of men have PSA tests and rectal examinations routinely.

Not everyone needs heart tests

There are now more ways than ever to evaluate the health of your heart. But none are routinely recommended if you're at low risk and have no signs or symptoms of cardiovascular disease. That's right: in the absence of symptoms or a high risk of cardiovascular disease, it's generally safe to skip EKGs, stress tests, and other cardiac tests.

Yet many people have these tests as part of their routine care. Why is this a problem? Having these tests without a compelling reason comes with risks, especially false positive results that can lead to invasive testing and unneeded treatment.

Four more reasons to avoid unnecessary care

Besides the concerns mentioned already, there are other reasons to avoid unnecessary care, including:

  • The discomfort or complications of testing. If you're needle-phobic, getting a blood test is a big deal. And while complications of noninvasive testing are rare (such as a skin infection from a blood test), they can occur.
  • The anxiety associated with waiting to find out test results
  • False reassurance that comes with false negatives (results that are normal or nearly so, suggesting no disease when disease is actually present)
  • All treatments have side effects. Even minor reactions — like occasional nausea or constipation — seem unacceptable if there's no reason to expect benefit from treatment.

The bottom line

You may believe your doctor wants you to continue with your current schedule of tests and treatments, while they might think this is your preference! It's worth discussing if you haven't already, especially if you suspect you may be taking pills or getting tests you don't truly need.

If your doctor says you can safely skip certain tests, treatments, and supplements, it doesn't mean that he or she is neglecting your health or that you don't deserve great health care! It's likely that the balance of risks and benefits simply doesn't support doing these things.

Less unnecessary care could free up resources for those who need it most. And it could save you time, money, and unnecessary risks or side effects, thus improving your health. It's a good example of how less can truly be more.

The popularity of e-bikes and e-scooters is soaring, but are they safe?

Woman in jeans, blue blazer, and helmet riding electric scooter on pathway with flowers and trees in background

Ever ridden an e-scooter or e-bike? The convenience, affordability, and flat-out fun of these “micromobility” modes of transportation are undeniable. But did it also seem a bit dangerous?

In fact, the rate of accidents involving e-bikes and e-scooters is climbing. Maybe that shouldn’t be surprising given their dramatic jump in popularity. And then there’s the way riders often use them: at high speed, near cars and pedestrians, and on roads and sidewalks that weren’t designed for them.

Disruptive innovations, such as e-bikes and e-scooters, inevitably come with downsides. So, how can we minimize risks for accidents?

E-bikes, e-scooters, and injuries

Between 2018 and 2022, sales of e-bikes rose from around 250,000 per year to more than a million. E-bike and e-scooter rentals have also increased dramatically. As their popularity grows, emergency rooms are seeing many more people injured while riding e-bikes and e-scooters.

A 2024 study in JAMA Network Open highlights this. Researchers drew data from the National Electronic Injury Surveillance System, which is run by the US Consumer Product Safety Commission. They analyzed ER care between 2017 and 2022 for people injured while riding an e-bike or e-scooter, compared with people injured while riding conventional bikes and scooters.

What did the study find?

During the six-year study period, roughly three million people riding e-bikes, e-scooters, or their conventional counterparts sought care in the ER, including about 45,500 e-bike riders and 190,000 e-scooter riders, and about 2.5 million conventional bike riders and 305,000 conventional scooter riders.

Certain themes emerged around e-micromobility:

ER care spiked upward

  • E-bike injuries more than doubled every year, going from 751 in 2017 to 23,493 in 2022.
  • E-scooter injuries increased by more than 45% every year, going from 8,566 in 2017 to 56,847 in 2022.

More risky behavior

  • 43% of e-bike and e-scooter riders wore helmets versus 52% for conventional micromobility riders
  • 7% of e-bike riders and 9% of e-scooter riders were drinking before their accidents versus 4% of conventional bike riders and 3% of conventional scooter riders.

More accidents occurred in urban areas compared with rural settings:

  • 83% of e-bike and e-scooter accidents
  • 71% of conventional bike and scooter accidents.

All riders experienced similar types of injuries: scrapes, bruises, broken bones, and head and neck injuries were most common.

What are the limitations of this study?

This study only included people evaluated in an ER, so it excluded people with less severe injuries — and even those with significant injuries who didn’t go to an ER. Some may have sought no care at all, or gone to a primary care practice or walk-in clinic to avoid costly ER care or for other reasons.

Nor did the study count injuries suffered by pedestrians injured by e-bike or e-scooter riders. Property damage, such as damage to a car, wasn’t calculated.

And ultimately the study cannot compare the safety of e-bikes and e-scooters with conventional options. That’s because no data were collected on the number of miles traveled using a particular mode of transportation, or over how much time.

How can you avoid e-bike or e-scooter injuries?

Ten common-sense precautions can help you avoid injuries and ER visits:

  • Wear a helmet. If you’re renting an e-bike or e-scooter, you may need to bring your own since many rental systems do not provide helmets.
  • Practice. E-bikes are much heavier than conventional bicycles and may handle differently. And many adults have not ridden a scooter since elementary school! So if you aren’t familiar with riding an e-bike or e-scooter, practice in a safe location where there’s no traffic or pedestrians.
  • Follow road rules. Ride on available bike lanes and avoid sidewalks. On an e-bike, use arm signals to alert those nearby of your intentions to turn or change lanes. (On an e-scooter, it’s best to keep both hands on the handle bars at all times.).
  • Slow down. Some e-bikes approach speeds of 30 miles per hour. The faster you go, the less time you have to react to unexpected potholes or veering vehicles, and the more serious an injury is likely to be if you have an accident.
  • Lower risks. Don’t ride while under the influence of alcohol or drugs, or use your phone while moving.
  • Go it alone. Don’t add riders. Most e-bikes and e-scooters are built for one rider at a time.
  • Ride defensively. Watch out for potholes or opening car doors.
  • Reflect. Wear reflective clothing or attach a light if riding at night.
  • Call out. Announce your presence to others. For example, shout “on your left!” as you approach pedestrians or slower riders that you intend to pass.
  • Lobby. Reach out to local politicians to create bike lanes and other infrastructure to make micromobility safer.

The bottom line

Whether it’s part of your daily commute, an occasional quick zip from point A to point B, or just a ride for the fun of it, e-bikes and e-scooters are a great way to get around. Though they do come with some risk, you can do a lot to minimize the odds of wrapping up your travels with a trip to an ER.

Mpox is back: What to know and do

Gloved hand holding a blood specimen tube with MPOX label; background is lab testing form for MPOX, vaccine bottles, cells

Ever heard of mpox? Wondering why it’s back in the news?

Many of us first learned about mpox (formerly called monkeypox) in 2022, when the largest known outbreak spread to nearly 100,000 people in more than 100 countries. While mpox often circulates in central and western Africa, the 2022 outbreak quickly spread from the Democratic Republic of the Congo (DRC) to places it had never been detected before. In the US alone, it caused more than 32,000 infections and 58 deaths.

Now, a new outbreak of mpox has put it back in the news. What should you know — and do — about this latest international health emergency? What are your risks? Are vaccines available? If you get mpox, how can you avoid spreading it?

What’s different about the 2024 mpox outbreak?

This time, a new strain of the virus (called Clade 1b) is spreading quickly. That’s why the World Health Organization (WHO) declared a second mpox global health emergency in August 2024.

Already, more than 15,600 cases and 500 deaths have been reported, mostly in the DRC. And mpox has been found in countries that previously hadn’t identified any cases, including Burundi, Kenya, Rwanda, and Uganda. Recent cases diagnosed in Sweden and Thailand have public health officials bracing for additional international spread, including to Asia, Europe, and the US.

6 things to know about mpox

What is mpox and how does it spread?

Mpox is a viral infection caused by the same family of viruses as smallpox. In central and western Africa it’s common in certain animals, including squirrels and rats. People can become infected after contact with infected animals. Mpox can spread from person to person through close physical contact, including sex.

What are the symptoms of mpox?

Mpox causes flulike symptoms, fever, headache, enlarged lymph nodes, and a unique rash. The rash usually begins a few days into the illness as small flat spots. The spots evolve over a week or two to become small fluid-filled bumps (vesicles) similar to chickenpox, and then larger pus-filled blisters. Over another week or two, the blisters scab over and heal. Once that happens, a person is no longer contagious.

Although the disease is usually mild, some people develop complications. Serious complications include pneumonia, vision loss due to eye infection, and sepsis, a life-threatening infection.

What is your risk of getting mpox?

Location and activities factor into your risk for developing mpox.

Risk increases if you

  • have close physical contact with an infected animal or person
  • have contact with bedding, clothes, or other objects or surfaces touched by an infected person
  • live in or visit a place where the mpox virus is endemic — that means present in the environment, such as in the soil or infected animals or people
  • are a man who has sex with men
  • have many sexual partners.

When people get mpox, risk factors for experiencing more severe disease or complications like pneumonia include:

  • pregnancy
  • young age (especially children younger than age 1)
  • having a weakened immune system
  • having eczema (because this weakens the protective skin barrier).

Why is the new mpox outbreak so worrisome?

The new outbreak of mpox is especially worrisome because the strain of the virus is deadlier than in 2022. The virus is spreading more quickly and reaching places where mpox had not previously been found.

In addition, the new outbreak has disproportionately affected kids and teens in resource-poor countries. Many are already suffering with malnutrition, or other infections such as cholera.

It’s worth noting that the strain of mpox from the 2022 outbreak (Clade 1) is still circulating at a low level in the US. Right now, fewer than 15 people a week are diagnosed with it and treatment is available.

Are there mpox vaccines and treatments?

There are two vaccines available to prevent mpox in the US:

  • Jynneos is approved to prevent mpox and smallpox. It requires two doses four weeks apart.
  • A vaccine called ACAM2000 is approved for preventing smallpox and is considered effective for mpox. It could be made available if needed, but its potential side effects make it a second choice.

Resource-poor countries in Africa, Asia, and elsewhere have had limited access to vaccines. Even in resource-rich countries like Europe and the US, vaccine hesitancy has been an obstacle to containing the outbreak. In one study, only half of a vulnerable population in Illinois received the initial dose of the mpox vaccine, and only a quarter received both recommended doses.

An antiviral drug called tecovirimat is approved to treat smallpox. Animal studies suggest it may be effective in treating mpox as well. Now being investigated as an mpox treatment, the drug may be available by enrolling in a study. A 2024 study found tecovirimat did not reduce the length of time adults and children with Clade 1 mpox had symptoms. However, the death rate (1.7%) was half of what was expected. But it’s unclear whether the low death rate was actually due to drug treatment.

How can someone with mpox avoid spreading it?

If you are diagnosed with mpox, it’s important to take these measures to avoid infecting others:

  • Avoid close contact with others until your skin lesions have healed.
  • Wear a well-fitting medical mask while near others; those visiting you should wear a mask as well.
  • Stay several feet or more away from others.
  • Use a separate bedroom and bathroom.
  • Clean all surfaces you’ve touched.
  • Don’t share eating utensils, towels, or bedding with others.
  • Increase room ventilation by opening windows or using a high-efficiency particulate air (HEPA) purifier.

Some experts recommend avoiding contact with pets or other animals because they could become infected and spread the disease to new animal species in new places.

The bottom line

Will mpox be the next pandemic? That’s unlikely. The virus that causes mpox spreads mainly by direct contact — unlike the virus that causes COVID-19, which spreads through small respiratory droplets that are easily breathed in. Also, people with mpox who are contagious typically have obvious symptoms, so they can take steps to avoid spread.

Currently, the risk mpox poses to most people in the US appears to be quite low. To help make sure it stays that way and to help countries where mpox is common, US public health officials are working with their counterparts in other countries to contain the outbreak. To be successful, we’ll need a robust. well-coordinated international effort, including financial support to resource-poor countries to fund educational programs, vaccination, testing, and treatment.

Boosting your child’s immune system

A smiling child with her arms up, holding a colorful umbrella

Parents often wonder: What can we do to keep our children healthy? Are there ways to boost the immune system and ward off illnesses?

The answer is yes — but there are no magic wands or magic supplements. The best way to keep the immune system healthy is, basically, to take necessary steps to keep healthy. As boring as that sounds, it’s tried and true.

Here’s what you can do to help keep your children healthy this school year.

Give them a healthy diet

By healthy I mean a diet with lots of fruits and vegetables (five servings a day are recommended, and they should take up half of every meal plate), whole grains, and lean protein. A healthy diet also has dairy or another source of calcium, and healthy fats like vegetable oils.

The foods to avoid are processed foods, foods with added sugar, and foods with unhealthy fats, like the saturated fats found in animal products. That doesn’t mean your child can’t ever eat cookies or ice cream. But if you want to your child to be healthy, they shouldn’t eat those foods every day. (The Academy of Nutrition and Dietetics has suggestions for healthier baked goods and other ways to make your family’s diet healthier).

There are many supplements that claim to boost your immune system. While the jury is still out as to whether most of them make a real difference, none of them take the place of a healthy diet. If you have a child who refuses vegetables or otherwise has a limited diet, a multivitamin with iron may make sense; talk to your doctor about whether vitamins or supplements are a good idea for your child.

Make sure they get enough sleep

We all need sleep to refresh and recharge our bodies, and that includes children. The amount of sleep a child needs varies by age (from 12 to 16 hours a day for infants to eight to 10 hours for teens), and also from child to child (some just need more than others). You can encourage healthy sleep by limiting screens — for teens, devices really should be shut off an hour or two before bedtime, and preferably not be in the bedroom at night — and keeping to a regular schedule.

Get them active

Exercise keeps us healthy and less likely to get sick. Children should really be active for an hour a day. “Active” doesn’t have to mean playing a sport or going to the gym; it could be playing at the playground or going for a walk. More is not necessarily better; if you have a child who is a serious athlete, exercising several hours a day, make sure that the exercise isn’t eating into sleep or causing burnout, both of which could cause problems with the immune system.

Manage stress

Stress makes us less healthy and more prone to infection. Make sure that kids have downtime to play, and access to activities and people that make them happy. Spend time together as a family, and create opportunities for your children to talk about anything that might be worrying them. If you have concerns about your child’s moods or emotional health, talk to your doctor.

Make sure they are up to date on important vaccines

Immunizations protect us from all sorts of illnesses. Check with your doctor to see if your child is up to date on immunizations. The flu shot is recommended yearly for all people 6 months of age or older.

Don’t forget the simple precautions

Everyone in the family can take simple precautions to help stay healthy. Wash your hands. Cover your coughs and sneezes with your elbow. Stay away from sick people to the extent that you can. Masks can help, too, especially in crowded indoor spaces.

If your child has a health problem that could make it harder to fight off an infection, talk to your doctor about any extra or different precautions you should take.

A fresh look at risks for developing young-onset dementia

A light blue background with a side view of human head illustrated in dark blue gears, some flying away at the back of the brain; concept is young-onset dementia

Dementia usually develops in people ages 65 years and older. So-called young-onset dementia, occurring in those younger than age 65, is uncommon. Now, a new study published in December 2023 in JAMA Neurology has identified 15 factors linked to a higher risk of young-onset dementia.

Let’s see what they found, and — most importantly — what you can do to reduce your own risks.

Are early dementia and young-onset dementia the same?

No. Experts think of early dementia as the first stage in dementia. Mild cognitive impairment and mild dementia are forms of early dementia. So, someone age 50, 65, or 88 could have early dementia.

Young-onset dementia refers to the age at which dementia is diagnosed. A person has young-onset dementia if symptoms and diagnosis occur before age 65.

What has previous research shown?

A previous study of men in Sweden identified some risk factors for young-onset dementia, including high blood pressure, stroke, depression, alcohol use disorder, vitamin D deficiency, drug use disorder, and overall cognitive function.

What to know about the new study

In the new study, a research team in the Netherlands and the United Kingdom looked at data from the UK Biobank. The biobank follows about half a million individuals in the United Kingdom who were 37 to 73 years old when they first joined the project between 2006 and 2010. Most participants identified as white (89%), and the remaining 11% were described only as “other.” Slightly more than half of the participants (54%) were women.

The researchers excluded anyone age 65 or older and people who already had dementia at the start of the study, leaving 356,052 participants for the analyses. Over roughly a decade, 485 participants developed young-onset dementia. The researchers compared participants who did and did not develop young-onset dementia to identify possible risk factors.

What did the researchers learn about risks for young-onset dementia?

In reviewing the results, I think it is helpful to group the risk factors into several categories, and then to examine each of them. These risks may act on the brain directly or indirectly.

Eight factors that we know or strongly suspect cause dementia:

  • Genes: Carrying two apolipoprotein E (APOE) ε4 alleles is a major genetic risk factor for Alzheimer’s disease. The risk is thought to be caused by the APOE ε4 protein not clearing amyloid efficiently from the brain. This allows amyloid to accumulate and cause plaques, which starts the cascade to cell death and Alzheimer’s disease.
  • Being diagnosed with alcohol use disorder (AUD) has been associated with damage to several parts of the brain, including the frontal lobes, which leads to trouble with executive function and working memory. When combined with poor nutrition, AUD also harms small regions connected to the hippocampus that are critical for forming new memories.
  • Being socially isolated is a major risk factor for dementia. Although the exact mechanism is unknown, it may be because our brains evolved, in large part, for social interactions. Individuals with fewer social contacts have fewer social interactions, and simply don’t use their brains enough to keep them healthy.
  • Not getting enough vitamin D can lead to more viral infections. A number of studies suggest that certain viral infections increase your risk of dementia.
  • Not hearing well increases your risk for dementia, as I discussed in a prior post. This is likely because of reduced brain stimulation and reduced social interactions. Using hearing aids lessens that risk.
  • Previously having had a stroke is a risk factor because strokes damage the brain directly, which can lead to vascular dementia.
  • Having heart disease is a major risk factor for strokes, which can then lead to vascular dementia.
  • Having diabetes if you’re a man can lead to dementia in many different ways. Why only if you’re a man? The researchers suggest that it is because middle-aged men are more likely to have a diabetes-related ministrokes than middle-aged women, which can, again, lead to vascular dementia.

Two factors that reduce cognitive reserve

Cognitive reserve can be described as our capacity to think, improvise, and problem-solve even as our brains change with age. These two risk factors make it more likely that dementia symptoms will show up at a younger age.

  • Having less formal education may affect your familiarity with the items on the pencil-and-paper cognitive tests that are used to diagnose dementia.
  • Having lower socioeconomic status may be related to lower-quality education.

Is every factor identified in the study a clear risk?

No, and here’s why not: Sometimes research turns up apparent risk factors that might be due to reverse causation. It’s possible, for example, that symptoms of impending dementia appear to be risk factors because they become noticeable before obvious dementia is diagnosed.

  • Lower handgrip strength is a sign of frailty, which is often associated with dementia.
  • No alcohol use is a risk factor because people may stop drinking when they develop memory loss (also known as the “healthy drinker effect” in dementia).
  • Depression is a risk factor because many people get sad when they have trouble remembering or when they are worried about having dementia.

Lastly, there are risk factors that could be either a contributing cause or a result of the impending dementia.

  • High C-reactive protein is a sign of inflammation.
  • Orthostatic hypotension is an abnormal drop in blood pressure when a person stands up after lying down or sitting. While this condition can lead to brain damage and dementia, it can also be a result of some types of dementia, such as Parkinson’s disease dementia and dementia with Lewy bodies.

What can you do to prevent young-onset dementia?

Taking these five steps can reduce your risk for developing dementia before age 65:

  • Don’t drink alcohol in excess.
  • Seek opportunities to socialize with others regularly.
  • Make sure that you’re getting enough vitamin D. You can make your own vitamin D if your skin (without sunblock) is exposed to sunlight. But in northern climates you might need to take a supplement, especially in the winter. Because vitamin D can interact with other medications, ask your doctor about this option.
  • Make sure you are hearing well and use hearing aids if you are not.
  • Exercise regularly, eat a healthy diet, maintain a healthy body weight, and work with your doctor to reduce your risk of strokes, heart disease, and diabetes.

Want to cool down? 14 ideas to try

photo of a hand holding a metal scoop filled with ice in front of a yellow background

You’re huffing and puffing and starting to sweat — and that’s just from walking across the parking lot in blistering heat and humidity. This summer has left us all struggling to stay cool.

“The last 13 months have been the hottest on record. We’re seeing increased levels of heat-related illness, and it started earlier in the season we’re used to,” says Dr. Tess Wiskel, a climate change and human health fellow at the Center for Climate, Health, and the Global Environment, and an emergency physician at Beth Israel Deaconess Medical Center.

Don’t wait until you’re overheated to figure out how to cool down. Be wary of high temperature risks throughout your day and practice ways to avoid them. Here are 14 ideas to get you started.

Cover the basics

  • Become a weather expert. Use a weather app on your smartphone and pay attention to the hourly temperatures, not just daily highs and lows. Note the hottest points of the day and plan your schedule around them.
  • Stay hydrated. One way the body cools down is by sweating. As moisture on the skin evaporates, it takes heat with it. That’s called evaporative heat loss. But you must replace the fluids you lose through a combination of drinks and water-rich foods. Generally, the National Academy of Medicine recommends totals of about 11 cups (88 ounces) per day for women and 15 cups (120 ounces) per day for men. If you spend a lot of time outdoors or are sweating a lot, you’ll need even more fluids.
  • Seek air-conditioned environments. As much as possible, hang out in air-conditioned indoor spaces during the hottest points of the day. If you don’t have AC, go to a shopping mall, public library, movie theater, or a community cooling center.
  • Use fans correctly. Another way the body cools down is by channeling blood and body heat to vessels near the skin’s surface, where heat escapes. A fan can blow that heat away from your body and keep you cool, but not if the surrounding air is hot. “In that case, wet your skin, even with a spray bottle or a wet wipe. The fan will promote evaporative heat loss,” Dr. Wiskel says.
  • Take breaks. Pace yourself when doing outdoor activity. “Physical work produces its own heat at the same time you’re being heated from outside,” Dr. Wiskel says. “Be active for short periods and rest in between.”

Pack and dress for heat

  • Bring cool-downs with you. Any time you leave your home, bring plenty of water. Even better: bring a handheld fan, wet wipes, and ice packs. That way you’re prepared if you get stuck outside.
  • Wear loose clothing. Lightweight, loose-fitting garments allow air to get to your skin, promoting evaporative heat loss to keep you cool when you sweat.
  • Try high-tech clothes. Consider wearing clothes with cooling technology (such as tops, bottoms, hats, or neck gaiters). They work in various ways. For example, a garment might be made of a special fabric that’s activated with water and stays damp for a long period, continually pulling heat from your body.

Try DIY cool downs

  • Make a DIY cooling garment. Dunk a kitchen towel or cotton T-shirt in cold water, wear it on your head, neck, or torso, and then rewet the fabric as it dries. Or buy higher-tech versions made with fabrics and gels designed to stay cool longer.
  • Eat or drink something cold. A cool glass of water, ice chips, or a popsicle help fight dehydration and might help lower your body’s core temperature. Just don’t ingest anything too quickly. Dr. Wiskel says it might cause gastrointestinal upset.
  • Cool off with a shower or bath. Experts debate the best temperature for water to cool you down. Some maintain that cool water constricts blood vessels and sends heat back to the core, making you hot again. Others maintain that chilly water cools the blood vessels and sends cooled blood to the core. Dr. Wiskel’s take: “Immerse yourself in water that’s cooler than your body temperature. The water can be tepid. Once you’re out of the water, stand in front of a fan to promote evaporative heat loss.”
  • Submerge your forearms. If you can’t take a shower or bath, try a trick used by the US Army: submerge your hands, forearms, and elbows in ice water for five minutes. This helps send cooled blood moving through blood vessels back to your core.
  • Apply ice or cold packs. A water-free method to cool blood vessels involves placing ice packs in areas near large blood vessels such as the elbows, underarms, neck, or inside the legs near the groin area.

Know when to get help

If you’re not cooling down after trying numerous methods, Dr. Wiskel advises that you seek care. Call your doctor’s office or call 911 if you’re exhibiting signs of heat exhaustion, such as

  • excessive sweating
  • headache
  • feeling faint or dizzy
  • cold, clammy skin
  • a fast or weak pulse
  • extreme fatigue
  • muscle cramps.

Pay extra attention to those symptoms, especially if you’re vulnerable to heat and aren’t able to regulate your temperature well.

“People at high risk include older adults, babies and children, those who are pregnant, people who take medications that make them less able to sweat, people who work outdoors, and people with certain health conditions, including cardiovascular disease,” Dr. Wiskel says. “And if you’re not high risk, check in on people who are.”

How well do you score on brain health?

illustration of a human brain shown in colorful triangular prisms against a gray background; concept is brain health

Need another jolt of motivation to shore up a resolution to shed weight, sleep more soundly, boost nutrition or exercise levels, or cut back on alcohol? Then you'll be pleased to learn that any (and all) of these efforts can also add up to better brain health.

An international study led by researchers at the McCance Center for Brain Health at Massachusetts General Hospital devised and validated a Brain Care Score (BCS) card that makes it easy to total up what you're doing well and where you might do better. The prize is a healthier brain — specifically a lower risk for dementia and strokes.

Designed to predict how current habits might impact future brain health, the user-friendly scorecard is apparently the first of its kind, says Dr. Andrew Budson, a lecturer in neurology at Harvard Medical School.

"It's a real service that the researchers have developed a scale like this and completed the first study to determine if scoring worse on this scale raises your risk for dementia and stroke," says Dr. Budson, who wasn't involved in the analysis. "On one hand, no one's done something quite like this before. On the other, however, it's really wrapping together health factors everyone has known for a number of years in new packaging."

What's included on the scorecard?

Called the McCance Brain Care Score, the card tallies points from 12 physical, lifestyle, and social-emotional domains.

Physical components relate to

  • blood pressure
  • blood sugar
  • cholesterol
  • body mass index (BMI).

Lifestyle components include

  • nutrition
  • alcohol intake
  • smoking
  • aerobic activities
  • sleep.

Social-emotional factors inquire about

  • stress management
  • social relationships
  • meaning in life.

Each response is given a score of 0, 1, or 2, with the highest possible score totaling 21. Higher scores suggest better brain care.

"All these physical and lifestyle factors can contribute to the risk of dementia to some extent through strokes," Dr. Budson says. "Those that aren't a risk through strokes are usually related to the fact that a healthy brain is a brain that's using all of its parts. Engaging in healthy relationships and meaningful activities helps us maintain good brain structure and function."

What did the analysis involve?

The study was published online in Frontiers of Neurology in December 2023. It involved nearly 399,000 adults ages 40 through 69 (average age 57; 54% women) who contributed personal health information to the UK Biobank.

During an average follow-up period of 12.5 years, participants recorded 5,354 new cases of dementia and 7,259 strokes. Researchers found that participants with higher Brain Care Scores at the study's start had lower risks of developing dementia or strokes over time.

These threats to health and independence take a stunning — and growing — toll on people in the US. Dementia affects one in seven Americans, a rate expected to triple by 2050. Meanwhile, more than 795,000 people in the United States suffer a stroke each year, according to the CDC.

What did the study find?

Each five-point step higher in the BCS rating assigned when the study began was linked to significantly lower risks of dementia and stroke, with those odds varying by age group:

  • Participants younger than 50 at the study's start were 59% less likely to develop dementia and 48% less likely to have a stroke with each five-point higher score on BCS.
  • Participants 50 through 59 at the study's start were 32% less likely to develop dementia and 52% less likely to have a stroke with each five-point higher score on BCS.

But those brain disease benefits appeared to diminish for those older than 59 at the study's start. This group experienced only 8% lower odds of dementia and a 33% lower risk of stroke with each five-point higher score on BCS. Study authors theorized that some of these participants may have already been experiencing early dementia, which is difficult to detect until it progresses.

"I feel very comfortable that the study's conclusions are entirely correct, because all the factors that go into its BCS are well-known things people can do to reduce their risk of stroke and dementia," Dr. Budson says.

What are the study's limitations?

However, Dr. Budson notes that the study did have a couple of limitations,. The UK Biobank fell just short of collecting all the components of the BCS in its dataset, lacking meaning-of-life questions. So its scores ranged from 0 to 19, not up to 21. "It's a practical limitation, but it should be acknowledged that so far, there have been no studies to validate the actual 21-point scale they're recommending we use," he says.

The analysis also evaluated participants' scores at just one point in time instead of several, Dr. Budson says. Future research should determine whether people can lower their stroke and dementia risk by improving their BCS over time with behavior and lifestyle changes.

How can you play this game at home?

While better brain health may be the clear prize of a higher score, it's far from the only benefit. That's because improving any health component of the BCS also benefits our overall well-being.

"By improving these factors, not only will people help their brain, but they'll also help their heart and reduce their risk of cancer," Dr. Budson adds. "These factors will absolutely also improve your psychological health, which is certainly an important part of brain health."

The scale's simple breakdown of health factors also makes it easy to focus on tweaking one or two without getting overwhelmed.

"Let's say someone's nutrition isn't perfect — and they know it — but they're not willing to change their diet. Fine. They can then decide to do more aerobic exercise, for example, or to stop drinking, or to get the sleep their body needs," he says.

What one change could put you on a path to better brain health?

If he had to choose just one factor to improve brain health, Dr. Budson would focus on meaning of life, "which means you generally feel your life has meaning or purpose," he says. To do that, he suggests giving deep, quiet thought to what you wish your life's purpose to be, whether you expect to live a long time or just a few years.

"Once you have a purpose, then you have a reason to follow through with assessing all the other items on the BCS scale and seeing what you can do so you'll be around longer, and be competent and capable longer, to help fulfill the meaning and purpose of your life," he says.

Want to stop harmful drinking? AA versus SMART Recovery

People seated in a circle in middle of large room; concept is peer support meeting for alcohol use recovery

Ready to address excessive drinking in your life? Many people find peer support helps them take steps toward recovery. Two well-known self-help organizations built around peer support are Alcoholics Anonymous (AA) and Self-Management and Recovery Training (SMART Recovery). While some people seeking recovery even attend both programs, others forego both options.

Why do people choose those different paths — and what do they like, dislike, and find helpful about their chosen option? To find out, researchers questioned 80 participants enrolled in a two-year study about recovery from alcohol use disorder (20 each in AA, SMART Recovery, both, or neither).

Dr. John F. Kelly, professor of psychiatry in addiction medicine at Harvard Medical School, led the study, which was published in the Journal of Substance Use and Addiction Treatment. Here he explains key findings and shares his perspective and advice for people seeking peer support to stop problematic drinking.

Camaraderie: A common theme for both groups

The most striking finding was that for people attending either group, camaraderie was by far the most important aspect.

“There’s something about the connection with other people with similar experiences that helps decrease the self-stigma and shame that people have around this issue,” says Dr. Kelly, who founded the Recovery Research Institute at Massachusetts General Hospital. “Seeing role models of people who found solutions and a way out, and championing these examples of successful recovery, is very powerful,” he adds.

What else do people appreciate about AA?

Founded in 1935, AA has been around far longer than SMART Recovery, which began in 1990. AA’s popularity makes it easy to find meetings, which was one benefit cited in the study. “Within a 45-minute drive of downtown Boston, there are 1,800 AA meetings a week, compared with just 30 SMART meetings,” says Dr. Kelly.

You can also find a wider variety of specialized AA meetings, including those catering to different age groups, women, or LGBTQ+ people, for example. Larger metropolitan areas may have meetings conducted in different languages, as well.

AA follows a 12-step program, defined as a set of spiritual principles that help people achieve sobriety. Yet hardly anyone in the study mentioned spirituality in their responses, says Dr. Kelly. In fact, other research suggests that about half the people attending AA don’t seem to have a strong sense of needing to believe in a formal deity or higher power. “Some people say that connection with other people is what makes it a spiritual experience,” he says.

What else draws people to SMART Recovery?

The study results confirm years of anecdotal reports about why people choose SMART Recovery over AA, says Dr. Kelly. “What attracts people to SMART Recovery is the organization’s focus on science and clinical evidence,” he says.

Their approach incorporates cognitive behavioral therapy (CBT) and motivational psychology into their support groups. The goal is to help participants to recognize and cope with the emotional and environmental triggers for their drinking. Still, in this study, people who chose SMART Recovery stayed with it for the social aspects, according to responses about what they like best about the program, says Dr. Kelly.

Compared to people who attended AA, study participants who chose SMART tended to have less severe problems with alcohol use. They had more education, higher rates of employment, and greater economic resources. They were also less likely to have had prior treatment or involvement with the criminal justice system. SMART may be a particularly good fit for people with that kind of profile.

People who attended both AA and SMART Recovery groups tended to be the most severely affected by their problems with alcohol, and were seeking anything and everything to get help. Those who attended neither program were less seriously affected.

What are other differences between AA and SMART Recovery?

While AA groups are led by members in recovery, SMART groups are led by trained facilitators who are not required to be in recovery themselves.

In the study, that lack of “lived experience” wasn’t perceived as a negative, although some people mentioned that they didn’t like some of the facilitators, Dr. Kelly says. However, a trained facilitator can gently stop and redirect members who engage in meandering, lengthy, and potentially irritating monologues (known as a “drunkalogue”) that may dominate group discussions. AA group leaders don’t intervene in that way and have no formal group facilitation training.

However, AA strongly encourages people who join the fellowship, as it is called, to have a sponsor. Sponsors are experienced members with at least one year of recovery who serve as mentors for new members and are available between meetings. SMART Recovery doesn’t have formal sponsors, but facilitators encourage people to swap phone numbers and reach out to each other between meetings.

Should you participate in a support group to stop drinking?

“When I’m counseling patients, I lay out the different options and let people decide which program seems like the best personal fit for them,” says Dr. Kelly.

Because AA has been around for much longer, he notes that there’s more evidence about what contributes most to success with this approach. Research shows the three factors that have the biggest positive effect on remission for alcohol misuse are:

  • Having a sponsor. This is the single most important factor influencing recovery.
  • Attending at least three meetings per week. Consistently showing up, especially during the first year, also appears to boost the odds of recovery.
  • Speaking at meetings. Saying something aloud in the group meetings — even if it’s just a sentence or two — reinforces the likelihood of ongoing recovery. It also makes it easier to connect with other members in the “meeting after the meeting.”
