If you’ve been on TikTok lately, you know it’s hard to avoid countless influencers touting a concept called sleepmaxxing. Their posts provide tips and tricks to get longer, better, and more restorative sleep. And why not? Sleep is considered a pillar of good health and is related to everything from brain health to cardiovascular health, and even diabetes.

But what exactly is sleepmaxxing? And how likely is it to deliver on claims of amped-up energy, a boost to the immune system, reducing stress levels, and improving your mood?

What is sleepmaxxing?

Depending on which social media platform you happen to be looking at, the recommended strategies for maximizing sleep differ. Tips include:

• taping your mouth shut while sleeping
• not drinking anything during the two hours before bedtime
• a cold room temperature
• a dark bedroom
• using a white noise machine
• not setting a morning alarm
• showering one hour before bedtime
• eliminating caffeine
• eating kiwis before going to bed
• taking magnesium and melatonin
• using weighted blankets
• getting 30 minutes of sunlight every day
• meditating daily for 30 minutes.

Does any research support sleepmaxxing?

A thorough search through PubMed, PsycNet, and Google Scholar reveals zero results for the terms “sleepmaxx” and “sleepmaxxing.” But wait — this certainly doesn’t mean that some influencer-recommended strategies are not evidence-based, just that the concept of sleepmaxxing, as a defined package, has not been scientifically studied. But yes, some of the strategies — including one uncomfortable, though popular, choice — lack evidence.

Can mouth-taping improve your sleep?

TikTok users have claimed that taping your mouth while you sleep has benefits, such as reducing snoring and improving bad breath. A team from the department of otolaryngology at George Washington University was prompted by all of the social media buzz on the topic to review research on the impact of nocturnal mouth taping. Spoiler alert: the authors note that most TikTok mouth-taping claims aren’t supported by research.

If you do snore, it’s important to discuss this with your medical team. Even if taping your mouth reduces your snoring, it can’t effectively treat a potential underlying cause of the snoring, such as allergies, asthma, or sleep apnea.

Sleepmaxxing or basic sleep hygiene?

Many strategies recommended by sleepmaxxers are essentially what sleep experts prescribe as good sleep hygiene, which has plenty of research backing its value. Common components of sleep hygiene are decreasing caffeine and alcohol consumption, increasing physical activity, sleep timing, reducing evening light exposure, limiting daytime naps, and having a cool bedroom.

While tips like these help many people enjoy restful sleep, those who have an insomnia disorder will need more help, as described below.

Melatonin, early bedtime, weighted blankets, and — kiwi fruit?

Other strategies suggested by sleepmaxxers are based on limited scientific data. For example:

• Taking melatonin is recommended by the American Academy of Sleep Medicine to treat circadian rhythm disorders such as jet lag. But it’s not recommended for insufficient sleep, poor sleep quality, or difficulty with falling asleep or staying asleep.
• Is it healthier to be asleep by 10 p.m.? One video that garnered more than a million views claims it is. While it is important to maximize morning sunlight exposure and minimize evening light exposure to regulate circadian rhythms, there is such variability in how much sleep someone requires and individual chronotypes (not to mention varying personal and professional responsibilities!) that it is difficult to state there is an ideal bedtime for everyone.
• While intriguing research has been done on weighted blankets, there is no convincing evidence that they are truly effective for the general adult population.
• Overall, it’s important to be cautious about the impact of the placebo effect on how someone sleeps. An analysis of more than 30 studies showed that roughly 64% of the drug response for a sleep medication in insomnia patients could be due to the placebo effect. A key takeaway is that studies that are not randomized controlled trials — such as this small study on 24 people suggesting that kiwi fruit may improve sleep — should be interpreted with a grain of salt.

Could you have orthosomnia?

The expectation of flawless sleep, night in and night out, is an unrealistic goal. Orthosomnia is a term that describes an unhealthy pursuit of perfect sleep. The pressure to get perfect sleep is embedded in the sleepmaxxing culture.

With more and more people able to access daily data about their sleep and other health metrics through consumer wearables, even a person who is objectively sleeping well can become unnecessarily concerned with optimizing their sleep. While prioritizing restful sleep is commendable, setting perfection as your goal is problematic. Even good sleepers vary from night to night, experiencing less than desirable sleep a couple of times per week.

It is also noteworthy that some of the most widely viewed recommendations on TikTok are not supported by scientific evidence.

Do you really need to fix your sleep?

A good first step is to understand whether or not there is anything that you need to fix! Consider tracking your sleep for a few weeks using a sleep diary, and pair this data with a consumer wearable (such as a Fitbit or Apple Watch). Both imperfectly capture sleep data when compared to the gold-standard tool sleep experts use (polysomnography, or a sleep study). However, combining the information can give you a reasonable assessment of your sleep status.

Regularly getting restful sleep can indeed boost health and mood. And all of us can benefit from following basic sleep hygiene tips. But if it takes you 30 minutes or more to fall asleep, or if you are up for 30 minutes or more in the middle of the night, and this happens three or more times per week, then consider reaching out to your health care team to seek further evaluation.

There are effective, nonmedication treatments that are proven to help you sleep better. One example is cognitive behavioral therapy for insomnia, which can dramatically improve insomnia symptoms in a matter of weeks.

Chocolates and flowers are great gifts for Valentine’s Day. But what if the gifts we give then or throughout the year could be truly life-changing? A gift that could save a life or free someone from dialysis?

You can do this. For people in need of an organ, tissue, or blood donation, a donor can give them a gift that exceeds the value of anything that you can buy. Fittingly, Valentine’s Day is also known as National Donor Day, a time for blood drives and sign-ups for organ and tissue donation. Have you ever wondered what can be donated? Had reservations about donating after death or concerns about risks for live donors? Read on.

The enormous impact of organ, tissue, or cell donation

Imagine you have kidney failure requiring dialysis 12 or more hours each week just to stay alive. Even with this, you know you’re still likely to die a premature death. Or, if your liver is failing, you may experience severe nausea, itching, and confusion; death may only be a matter of weeks or months away. For those with cancer in need of a bone marrow transplant, or someone who’s lost their vision due to corneal disease, finding a donor may be their only good option.

Organ or tissue donation can turn these problems around, giving recipients a chance at a long life, a better quality of life, or both. And yet, the number of people who need organ donation far exceeds compatible donors. While national surveys have found about 90% of Americans support organ donation, only 40% have signed up. More than 103,000 women, men, and children are awaiting an organ transplant in the US. About 6,200 die each year, still waiting.

What can you donate?

The list of ways to help has grown dramatically. Some organs, tissues, or cells can be donated while you’re alive; other donations are only possible after death. A single donor can help more than 80 people!

After death, people can donate:

• bone, cartilage, and tendons
• corneas
• face and hands (though uncommon, they are among the newest additions to this list)
• kidneys
• liver
• lungs
• heart and heart valves
• stomach and intestine
• nerves
• pancreas
• skin
• arteries and veins.

Live donations may include:

• birth tissue, such as the placenta, umbilical cord, and amniotic fluid, which can be used to help heal skin wounds or ulcers and prevent infection
• blood cells, serum, or bone marrow
• a kidney
• part of a lung
• part of the intestine, liver, or pancreas.

Becoming a donor after death: Questions and misconceptions

Common misconceptions about becoming an organ donor limit the number of people who are willing to sign up. For example, many people mistakenly believe that

• doctors won’t work as hard to save your life if you’re known to be an organ donor — or worse, doctors will harvest organs before death
• their religion forbids organ donation
• you cannot have an open-casket funeral if you donate your organs.

None of these is true, and none should discourage you from becoming an organ donor. Legitimate medical professionals always keep the patient’s interests front and center. Care would never be jeopardized due to a person’s choices around organ donation. Most major religions allow and support organ donation. If organ donation occurs after death, the clothed body will show no outward signs of organ donation, so an open-casket funeral is an option for organ donors.

Live donors: Blood, bone marrow, and organs

Have you ever donated blood? Congratulations, you’re a live donor! The risk for live donors varies depending on the intended donation, such as:

• Blood, platelets, or plasma: If you’re donating blood or blood products, there is little or no risk involved.
• Bone marrow: Donating bone marrow requires a minor surgical procedure. If general anesthesia is used, there is a chance of a reaction to the anesthesia. Bone marrow is removed through needles inserted into the back of the pelvis bones on each side. Back or hip pain is common, but can be controlled with pain relievers. The body quickly replaces the bone marrow removed, so no long-term problems are expected.
• Stem cells: Stem cells are found in bone marrow or umbilical cord blood. They also appear in small numbers in our blood and can be donated through a process similar to blood donation. This takes about seven or eight hours. Filgrastim, a medication that increases stem cell production, is given for a number of days beforehand. It can cause side effects such as flulike symptoms, bone pain, and fatigue, but these tend to resolve soon after the procedure.
• Kidney, lung, or liver: Surgery to donate a kidney or a portion of a lung or liver comes with a risk of complications, reactions to anesthesia, and significant recovery time. It’s no small matter to give a kidney, or part of a lung or liver.

The vast number of live organ donations occur without complications, and donors typically feel quite positive about the experience.

Who can donate?

Almost anyone can donate blood cells –– including stem cells –– or be a bone marrow, tissue, or organ donor. Exceptions include anyone with active cancer, widespread infection, or organs that aren’t healthy.

What about age? By itself, your age does not disqualify you from organ donation. In 2023, two out of five people donating organs were over 50. People in their 90s have donated organs upon their deaths and saved the lives of others.

However, bone marrow transplants may fail more often when the donor is older, so bone marrow donations by people over age 55 or 60 are usually avoided.

Finding a good match: Immune compatibility

For many transplants, the best results occur when there is immune compatibility between the donor and recipient. Compatibility is based largely on HLA typing, which analyzes genetically-determined proteins on the surface of most cells. These proteins help the immune system identify which cells qualify as foreign or self. Foreign cells trigger an immune attack; cells identified as self should not.

HLA typing can be done by a blood test or cheek swab. Close relatives tend to have the best HLA matches, but complete strangers may be a good match as well.

Fewer donors among people with certain HLA types make finding a match more challenging. Already existing health disparities, such as higher rates of kidney disease among Black Americans and communities of color, are worsened by lower numbers of donors from these communities, an inequity partly driven by a lack of trust in the medical system.

The bottom line

You can make an enormous impact by becoming a donor during your life or after death. In the US, you must opt in to be a donor after death. (Research suggests the opt-out approach many other countries use could significantly increase rates of organ donation in this country.)

I’m hopeful that organ donation in the US and throughout the world will increase over time. While you can still go with chocolates for Valentine’s Day, maybe this year you can also go bigger and become a donor.

If you've been cocooning due to winter’s cold, who can blame you? But a lack of activity isn't good for body or mind during any season. And whether you're deep in the grip of winter or fortunate to be basking in signs of spring, today is a good day to start exercising. If you’re not sure where to start — or why you should — we’ve shared tips and answers below.

Moving more: What’s in it for all of us?

We’re all supposed to strengthen our muscles at least twice a week and get a total at least 150 minutes of weekly aerobic activity (the kind that gets your heart and lungs working). But fewer than 18% of U.S. adults meet those weekly recommendations, according to the CDC.

How can choosing to become more active help? A brighter mood is one benefit: physical activity helps ease depression and anxiety, for example. And being sufficiently active — whether in short or longer chunks of time — also lowers your risk for health problems like

• heart disease
• stroke
• diabetes
• cancer
• brain shrinkage
• muscle loss
• weight gain
• poor posture
• poor balance
• back pain
• and even premature death.

What are your exercise obstacles?

Even when we understand these benefits, a range of obstacles may keep us on the couch.

Don’t like the cold? Have trouble standing, walking, or moving around easily? Just don’t like exercise? Don’t let obstacles like these stop you anymore. Try some workarounds.

• If it’s cold outside: It’s generally safe to exercise when the mercury is above 32° F and the ground is dry. The right gear for cold doesn’t need to be fancy. A warm jacket, a hat, gloves, heavy socks, and nonslip shoes are a great start. Layers of athletic clothing that wick away moisture while keeping you warm can help, too. Consider going for a brisk walk or hike, taking part in an orienteering event, or working out with battle ropes ($25 and up) that you attach to a tree.
• If you have mobility issues: Most workouts can be modified. For example, it might be easier to do an aerobics or weights workout in a pool, where buoyancy makes it easier to move and there’s little fear of falling. Or try a seated workout at home, such as chair yoga, tai chi, Pilates, or strength training. You’ll find an endless array of free seated workout videos on YouTube, but look for those created by a reliable source such as Silver Sneakers, or a physical therapist, certified personal trainer, or certified exercise instructor. Another option is an adaptive sports program in your community, such as adaptive basketball.
• If you can’t stand formal exercise: Skip a structured workout and just be more active throughout the day. Do some vigorous housework (like scrubbing a bathtub or vacuuming) or yard work, climb stairs, jog to the mailbox, jog from the parking lot to the grocery store, or do any activity that gets your heart and lungs working. Track your activity minutes with a smartphone (most devices come with built-in fitness apps) or wearable fitness tracker ($20 and up).
• If you’re stuck indoors: The pandemic showed us there are lots of indoor exercise options. If you’re looking for free options, do a body-weight workout, with exercises like planks and squats; follow a free exercise video online; practice yoga or tai chi; turn on music and dance; stretch; or do a resistance band workout. Or if it’s in the budget, get a treadmill, take an online exercise class, or work online with a personal trainer. The American Council on Exercise has a tool on its website to locate certified trainers in your area.

Is it hard to find time to exercise?

The good news is that any amount of physical activity is great for health. For example, a 2022 study found that racking up 15 to 20 minutes of weekly vigorous exercise (less than three minutes per day) was tied to lower risks of heart disease, cancer, and early death.

"We don't quite understand how it works, but we do know the body's metabolic machinery that imparts health benefits can be turned on by short bouts of movement spread across days or weeks," says Dr. Aaron Baggish, founder of Harvard-affiliated Massachusetts General Hospital's Cardiovascular Performance Program and an associate professor of medicine at Harvard Medical School.

And the more you exercise, Dr. Baggish says, the more benefits you accrue, such as better mood, better balance, and reduced risks of diabetes, high blood pressure, high cholesterol, and cognitive decline.

What’s the next step to take?

For most people, increasing activity is doable. If you have a heart condition, poor balance, muscle weakness, or you’re easily winded, talk to your doctor or get an evaluation from a physical therapist.

And no matter which activity you select, ease into it. When you’ve been inactive for a while, your muscles are vulnerable to injury if you do too much too soon.

“Your muscles may be sore initially if they are being asked to do more,” says Dr. Sarah Eby, a sports medicine specialist at Harvard-affiliated Spaulding Rehabilitation Hospital. “That’s normal. Just be sure to start low, and slowly increase your duration and intensity over time. Pick activities you enjoy and set small, measurable, and attainable goals, even if it’s as simple as walking five minutes every day this week.”

Remember: the aim is simply exercising more than you have been. And the more you move, the better.

ADHD, or attention deficit hyperactivity disorder, is the most common neurobehavioral disorder of childhood. It affects approximately 7% to 8% of all children and youth in the US. As the American Academy of Pediatrics (AAP) points out in their clinical practice guideline for ADHD, that’s more than the mental health system can handle, which means that pediatricians need to step up and help out.

So, if your child is having problems with attention, focus, hyperactivity, impulsivity, or some combination of those, and is at least 4 years old, your first step should be an appointment with your child’s primary care doctor.

What steps will your pediatrician take?

According to the AAP, here’s what your doctor should do:

Take a history. Your doctor should ask you lots of questions about what is going on. Be ready to give details and examples.

Ask you to fill out a questionnaire about your child. Your doctor should also give you a questionnaire to give to your child’s teacher or guidance counselor.

A diagnosis of ADHD is made only if a child has symptoms that are

• present in more than one setting: For most children, that would be both home and school. If symptoms are only present in one setting, it’s less likely to be ADHD and more likely to be related to that setting. For example, a child who only has problems at school may have a learning disability.
• causing a problem in both of those settings: If a child is active and/or easily distracted, but is getting good grades, isn’t causing problems in class, and has good relationships in school and at home, there is not a problem. It bears watching, but it could be just personality or temperament.

There are ADHD rating scales that have been studied and shown to be reliable, such as the Vanderbilt and the Conners assessments. These scales can be very helpful, not just in making diagnoses, but also in following the progress of a child over time.

Screen your child for other problems. There are problems that can mimic ADHD, such as learning disabilities, depression, or even hearing problems. Additionally, children who have ADHD can also have learning disabilities, depression, or substance use. It’s important to ask enough questions and get enough information to be sure.

Discussing treatment options for ADHD

If a diagnosis of ADHD is made, your pediatrician should discuss treatment options with you.

• For 4- and 5-year-olds: The best place to begin is really with parent training on managing behavior, and getting support in the classroom. Medications should only be considered in this age group if those interventions don’t help, and the child’s symptoms are causing significant problems.
• For 6- to 12-year-olds: Along with parent training and behavioral support, medications can be very helpful. Primary care providers can prescribe one of the FDA-approved medications for ADHD (stimulants, atomoxetine, guanfacine, or clonidine). In this age group, formal classroom support in the form of an Individualized Education Program (IEP) or a 504 plan should be in place.
• For 12- to 18-year-olds: The same school programs and behavioral health support should be in place. Medications can be helpful, but teens should be part of that decision process; shared decision-making is an important part of caring for teens, and for getting them ready to take on their own care when they become adults.

Follow-up care for a child with ADHD

Your pediatrician also should follow up with you and your child. Early on, there should be frequent visits while you figure out the diagnosis, as well as any other possible problems. And if medication is prescribed, frequent visits are needed initially as you figure out the best medication and dose and monitor for side effects.

After that, the frequency of the visits will depend on how things are going, but appointments should be regular and scheduled, not just made to respond to a problem. ADHD can be a lifelong problem, bringing different challenges at different times, and it’s important that you, your child, and your doctor meet regularly so that you can best meet those challenges.

Because together, you can.

Looking after a loved one who has prostate cancer can be overwhelming. Caregivers — usually partners, family members, or close friends — play crucial roles in supporting a patient's physical and psychological well-being. But what does that entail? You as a caregiver might not know what to say or how to help.

"Patients diagnosed with advanced cancer are facing their own mortality," says Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor in chief of the Harvard Medical School Guide to Prostate Diseases. "And they each process that in different ways."

Dr. Garnick emphasizes the need provide patients and families with the best information possible about the specifics of the diagnosis, symptoms, and available treatments. Some patients have near-miraculous responses to treatment, he says, even when they have very advanced cancer. "We let patients know that there are reasons to be optimistic, as treatments are improving on a regular basis," he says.

Communication

Dr. Garnick points out that clinicians should avoid words or phrases that can leave cancer patients feeling unempowered. A phrase like "Let's not worry about that now," for instance, is dismissive and doesn't respond to a patient's legitimate concerns. Saying "You're lucky your cancer is only stage 2" doesn't allow for the fear and anxiety a patient may have over his disease.

Along similar lines, "It's important for caregivers to be receptive to what their loved ones are saying," Dr. Garnick says. "Instead of minimizing or questioning what your loved one is telling you, try asking 'What do you need? Tell me what you think is going to help you feel better.'"

While it's natural to offer reassurance, you should also give your loved one space to express himself openly without offering quick solutions. Be aware that treatment can lead to emotional ups and downs, so expect mood fluctuations.

One of the most valuable tools you have as a caregiver is the relationship you've built with your loved one over the years. During this challenging time, remind yourself of the bonds you've created together. Shared memories, inside jokes, and mutual interests can provide strength and comfort.

Day-to-day practical support

Managing medications can be challenging. Cancer patients can take a dozen or more pills per day on varying schedules. You can help your loved one stay on track by setting up a pill organizer (available at most drugstores) that sorts medications according to when they're needed.

Patients with advanced prostate cancer are now being treated more often with drug combinations that include chemotherapy as well as hormonal therapies. Chemotherapy can leave patients feeling unusually cold, and patients may also get cold after experiencing hot flashes from hormonal therapy. So keep lots of blankets and warm hats on hand.

Collaborate on a journal where you and your loved one keep health information in one place. It should contain the names and contacts of clinicians on his team, as well as details of his treatment plan. The journal can also double as a diary where you both record treatment experiences.

You might be tasked with coordinating medical appointments. It's important to keep lists of questions you may have. Take notes so you have a record of what doctors and other people on his care team have told you. Also, you should take some time to familiarize yourself with your loved one's insurance policies or Medicare plans so you have a better understanding of what's covered.

Don't forget to take care of yourself!

As a caregiver, it's easy to get lost in your loved one's needs. But caring for someone with cancer while managing household responsibilities can also leave you feeling isolated, burned out, and even depressed. It's essential to also prioritize your own health and well-being.

Make sure that you get enough sleep and exercise. Keep up with your own checkups and screening. Try to eat well, and prepare meals ahead of time to reduce stress and save time on busy days. Take breaks! Caregiving can be intense, so take time to recharge by taking a walk, reading a book, or spending time with friends.

Here are some valuable resources that can help.

Help for Cancer Caregivers provides support on managing feelings and emotions, keeping healthy, day-to-day needs, working together, and long-distance caregiving.

The Prostate Cancer Foundation provides an array of educational materials, including a "caregiver's toolkit" that helps caregivers understand treatment options, side effects, and ways to be actively involved in the decision-making process.

The Patient Advocate Foundation offers case management services to help caregivers and patients understand insurance coverage, financial assistance programs, and other resources that can reduce the financial burden of cancer treatment.

School vacation coming up? Wondering how to spend that time? Given how tiring holidays can be — especially for parents who are working — it’s understandable why children are often allowed to spend hours with the TV, tablet, or video games. After all, happy, quiet kids make for happy parents who can finally get stuff done — or relax.

Except kids are spending way too much time in front of screens. According to the American Academy of Child and Adolescent Psychiatry, kids ages 8 to 12 are spending four to six hours a day watching or using screens — and tweens and teens are spending nine hours.

Given how enticing devices and social media can be, those numbers can easily go higher during unscheduled times like weekends and school vacation. That’s why it’s good to be proactive and come up with other activities. Below are some ideas for parents and caregivers to try. These are mostly good for kids through elementary school, but tweens and teens may enjoy some of them too.

Spending time off the screen

Go outside. This sounds obvious, but spending time outdoors is something kids do less than they used to — and it can be really fun. If you have a yard, go out into it and play hide-and-seek or build a fort from snow or anything else that’s around. If you don’t have a yard, go to a local park or just go for a walk. A scavenger hunt up and down the block or game of I Spy may be a good enticement.

Go to the library. Do this early on in vacation, so that your child has lots of books, puzzles, and games to pass the time. Check out as many as they allow and you can carry. Ask if a Library of Things is available at a branch near you: crafts, tools, musical instruments, birding kits, telescopes — even metal detectors may be checked out for free.

Build a fort in the living room. Use blankets or sheets over chairs; if you have a small tent, set it up. Bring in pillows, sleeping bags, and flashlights; let the kids sleep in it at night. Let it stay up all vacation.

Build a city in the living room. Use blocks, Legos, boxes (or anything else), and add roads, cars, people, animals, trains, and other toys. Let it stay up all vacation, and make it bigger every day.

Getting creative off the screen

Get creative. Go to the craft store and stock up on inexpensive supplies. Buy things like poster board, huge pieces of paper (you could use those for your city, too, to make parks, roads, and parking lots), paints, and markers. You can make a paper mural, a comic book, a story, posters, or whatever catches your child’s imagination. If you know how to knit or sew, think about teaching your child or making a simple project together.  Play music while you create.

Read out loud. There are so many books that are fun to read aloud. When my children were younger, we read the Harry Potter series out loud, as well as the Chronicles of Narnia and books by E.B. White and Roald Dahl. Act out the voices. Have some fun.

Have a puppet show. If you don’t have puppets, you can make some with socks — or you can hold up dolls or action figures and do the talking for them. You can make a makeshift stage by cutting out the back of a box and taping cloth (like a pillowcase) to fall over the front.

Get out the games. There are so many that work across the ages, like checkers, chess, Uno, Connect 4, Sorry, Twister, Clue, Scrabble, or Monopoly. We forget how much fun these can be.

Bake. You don’t have to get fancy — it’s fine to use mixes or pre-made cookie dough. There’s nothing better than baked goods straight from the oven, and adding frosting and decorations makes it even more fun. Turn on music and dance while things bake.

While parents or caregivers need to be involved with some of these activities (like the ones involving the oven, or reading out loud), kids can do many of them independently once you have it started. Which, really, is what children need: time to use their imagination and just play.

But you just may find that once you have things started, you'll want to play, too.

Nantucket, a beautiful, 14-mile-long island off the coast of Massachusetts, has a 40-point resiliency plan to help withstand the buffeting seas surrounding it as climate change takes a toll. Perhaps we can all benefit from creating individual resilience plans to help handle the big and small issues that erode our sense of well-being. But what is resilience and how do you cultivate it?

What is resilience?

Resilience is a psychological response that helps you adapt to life’s difficulties and seek a path forward through challenges.

“It’s a flexible mindset that helps you adapt, think critically, and stay focused on your values and what matters most,” says Luana Marques, an associate professor of psychiatry at Harvard Medical School.

While everyone has the ability to be resilient, your capacity for resilience can take a beating over time from chronic stress, perhaps from financial instability or staying in a job you dislike. The longer you’re in that situation, the harder it becomes to cope with it.

Fortunately, it’s possible to cultivate resilience. To do so, it helps to exercise resiliency skills as often as possible, even for minor stressors. Marques recommends the following strategies.

Shift your thoughts

In stressful situations, try to balance out your thoughts by adopting a broader perspective. “This will help you stop using the emotional part of your brain and start using the thinking part of your brain. For example, if you’re asking for a raise and your brain says you won’t get it, think about the things you’ve done in your job that are worthy of a raise. You’ll slow down the emotional response and shift your mindset from anxious to action,” Marques says.

Approach what you want

“When you’re anxious, stressed, or burned out, you tend to avoid things that make you uncomfortable. That can make you feel stuck,” Marques says. “What you need to do is get out of your comfort zone and take a step toward the thing you want, in spite of fear.”

For example: If you’re afraid of giving a presentation, create a PowerPoint and practice it with colleagues. If you’re having conflict at home, don’t walk away from your partner — schedule time to talk about what’s making you upset.

Align actions with your values

“Stress happens when your actions are not aligned with your values — the things that matter most to you or bring you joy. For example, you might feel stressed if you care most about your family but can’t be there for dinner, or care most about your health but drink a lot,” Marques says.

She suggests that you identify your top three values and make sure your daily actions align with them. If being with family is one of the three, make your time with them a priority — perhaps find a way to join them for a daily meal. If you get joy from a clean house, make daily tidying a priority.

Tips for success

Practice the shift, approach, and align strategies throughout the week. “One trick I use is looking at my calendar on Sunday and checking if my actions for the week are aligned with my values. If they aren’t, I try to change things around,” Marques says.

It’s also important to live as healthy a lifestyle as possible, which will help keep your brain functioning at its best.

Healthy lifestyle habits include:

• getting seven to nine hours of sleep per night
• following a healthy diet, such as a Mediterranean-style diet
• aiming for at least 150 minutes of moderate-intensity activities (such as brisk walking) each week — and adding on strength training at least twice a week
• if you drink alcohol, limiting yourself to no more than one drink per day for women and two drinks per day for men
• not smoking
• staying socially connected, whether in person, by phone or video calls, social media, or even text messages.

Need resilience training?

Even the best athletes have coaches, and you might benefit from resilience training.

Consider taking an online course, such as this one developed by Luana Marques. Or maybe turn to a therapist online or in person for help. Look for someone who specializes in cognitive behavioral therapy, which guides you to redirect negative thoughts to positive or productive ones.

Just don’t put off building resilience. Practicing as you face day-to-day stresses will help you learn skills to help navigate when dark clouds roll in and seas get rough.

Cheers! Salud! Prost!

Drinking to one’s health is a common tradition. But it may also be self-defeating: the alcohol that’s part of many toasts can actually harm your health.

Of course, alcohol consumption extends well past toasts. For millions of people, it’s a regular part of the dining experience, social and sports events, celebrations, and milestones. Alcohol plays a key role in many religious traditions. And the alcoholic beverage industry is a major economic force, responsible for more than $250 billion in sales annually in the US.

But there are many downsides to drinking: some are likely familiar (spoiler alert: it’s not great for your liver) while others are less well appreciated. And concerns about the risks of even moderate drinking are on the rise.

The negative effects of alcohol

Here are some of the most common problems associated with alcohol consumption (especially if excessive):

• liver disease, including cirrhosis and life-threatening liver failure requiring a liver transplant
• a higher risk of high blood pressure, heart failure, and dementia
• an increased risk of cancer (more on this below)
• a higher risk of injury, especially from drunk driving and falls (homicides and suicides are also often alcohol-related)
• lapses in judgment — for example, people who are drunk may engage in risky sexual behavior or use other drugs
• an increased risk of depression, anxiety, and addiction: these problems may impact one’s ability to establish and maintain social relationships and employment
• fetal alcohol syndrome: alcohol can damage a baby’s developing brain and cause other developmental abnormalities
• alcohol poisoning: many people don’t realize that if you drink enough alcohol over a short period of time, it can be fatal.

Heavy drinking can also cause problems well beyond the health of the drinker — it can damage important relationships. It’s all too common that problem drinking disrupts bonds with a spouse, family members, friends, coworkers, or employers.

Alcohol and cancer: A growing concern

In recent decades, a number of studies have linked drinking to higher rates of cancer, including cancers involving the

• liver
• colon
• breast
• mouth
• throat and esophagus.

In many cases, even moderate drinking (defined below) appears to increase risk. Despite this, less than half of the US public is aware of any alcohol-cancer connection. That’s why the Surgeon General issued an advisory in January 2025 recommending that alcoholic beverages carry new labels warning of the alcohol-cancer link and highlighting that no safe low level of alcohol consumption has been established. Changing the labels as suggested by the Surgeon General will require congressional action that may never happen.

Current alcoholic beverage labels in the US warn of the risks of driving under the influence of alcohol, adverse effects on general health, and risks for a developing fetus — but there’s no mention of cancer.

Are there any health benefits to drinking alcohol?

Alcohol has long been considered a “social lubricant” because drinking may encourage social interaction. Having a drink while getting together with family or friends is often part of many special occasions.

And not so long ago there was general consensus that drinking in moderation also came with health advantages, including a reduced risk of cardiovascular disease and diabetes. More recently, this belief has been called into question.

Even among the positive studies, potential health benefits are often quite small. In addition, alcohol may reduce the risk of one condition (such as cardiovascular disease) while increasing the risk of another (such as cancer). So it’s hard to predict who might actually benefit and who may be harmed more than helped by alcohol consumption. And the balance of risk and benefit likely varies from person to person, based on individual factors such as genetics and lifestyle factors.

Is drinking some alcohol better than drinking none?

A number of studies suggest the answer may be yes. For example, a 2018 study found that light drinkers (those consuming one to three drinks per week) had lower rates of cancer or death than those drinking less than one drink per week or none at all.

More recent studies (all published in 2023) came to similar conclusions. For example:

• A study of nearly a million people followed for more than 12 years found that abstainers had higher rates of death and chronic disease (including cardiovascular disease, Alzheimer’s disease, and chronic lung disease) than light or moderate drinkers.
• Researchers reporting on more than half a million people found that nondrinkers had higher rates of death than moderate drinkers.
• An analysis combining findings from 22 prior studies concluded that people who drank wine had lower rates of cardiovascular disease and related death than those who did not.

By contrast, another 2023 study found similar rates of death between nondrinkers and light to moderate drinkers.

It’s worth noting that current guidelines advise against drinking alcohol as a way to improve health.

How much alcohol is too much?

The answer to this important question has varied over time, but current US guidelines recommend that men who drink should limit intake to two drinks/day or less and women who drink should have no more than one drink/day. The definitions for a drink in the US are the common serving sizes for beer (12 ounces), wine (5 ounces), or distilled spirits/hard liquor (1.5 ounces).

A number of experts have recommended revision of the guidelines toward lower amounts, as more studies have linked even moderate alcohol consumption to health risks. Predictably, the alcoholic beverage industry opposes more restrictive guidelines.

Of course, no one needs to wait for new guidelines or warning labels to curb their drinking. Many are exploring ways to cut back, including the Dry January Challenge or alcohol-free drinks.

What we don’t know: The significant limitations of alcohol-related health research

Nearly all large studies regarding alcohol’s impact on health assess associations, not causation. So a higher rate of certain cancers may be associated with more alcohol consumption, but that doesn’t prove alcohol caused the cancer.

In addition, most rely on self-reporting that may be inaccurate, do not analyze binge drinking, do not assess alcohol consumption over a lifetime, or do not account for the fact that some study subjects may change their alcohol consumption due to alcohol-related health problems. These limitations make it hard to know how much to rely on studies that find health risks (or benefits) to alcohol consumption.

The bottom line

Assessing the risks and benefits of alcohol consumption remains an active area of research that may lead to major changes in official guidelines or warning labels.

But here’s one thing that hasn’t changed: many people like to drink. Even with more restrictive guidelines or new warning labels, it’s likely that plenty of folks will accept the risks of drinking alcohol. Still, it’s important to know what those risks are.

So, stay tuned. You can expect to hear about more research, debate, and controversy in the near future regarding the potential risks and benefits of drinking, and how much — if any — is ideal.

By midwinter, our urge to hibernate can start to feel constricting instead of cozy. What better antidote to being cooped up indoors than a bracing hike in the crisp air outdoors?

Winter backdrops are stark, serene, and often stunning. With fewer people on the trail, you may spot more creatures out and about. And it’s a prime opportunity to engage with the seasons and our living planet around us, says Dr. Stuart Harris, chief of the Division of Wilderness Medicine at Massachusetts General Hospital. But a multi-mile trek through rough, frosty terrain is far different than warm-weather hiking, requiring consideration of health and safety, he notes. Here’s what to know before you go.

Winter hiking: Safety first

“The challenge of hiking when environmental conditions are a little more demanding requires a very different approach on a winter’s day as opposed to a summer’s day,” Dr. Harris says. “But it gives us a chance to be immersed in the living world around us. It’s our ancient heritage.”

A safety-first attitude is especially important if you’re hiking with others of different ages and abilities — say, with older relatives or small children. It’s crucial to have both the right gear and the right mindset to make it enjoyable and safe for all involved.

Planning and preparation for winter hikes

Prepare well beforehand, especially if you’re mixing participants with vastly different fitness levels. Plan your route carefully, rather than just winging it.

People at the extremes of age — the very old or very young — are most vulnerable to frigid temperatures, and cold-weather hiking can be more taxing on the body. “Winter conditions can be more demanding on the heart than a perfectly-temperatured day,” Harris says. “Be mindful of the physical capabilities of everyone in your group, letting this define where you go. It’s supposed to be fun, not a punishing activity.”

Before setting out:

• Know how far, high, and remote you’re going to go, Dr. Harris advises, and check the forecast for the area where you’ll be hiking, taking wind chill and speed into account. Particularly at higher altitudes, weather can change from hour to hour, so keep abreast of expectations for temperature levels and any precipitation.
• Know if you’ll have access to emergency cell coverage if anything goes wrong.
• Always share plans with someone not on your hike, including expected route and time you’ll return. Fill out trailhead registers so park rangers will also know you’re on the trail in case of emergency.

What to wear for winter hikes

Prepare for extremes of cold, wind, snow, and even rain to avoid frostbite or hypothermia, when body temperature drops dangerously low.

• Dress in layers. Several thin layers of clothing are better than one thick one. Peel off a layer when you’re feeling warm in high sun and add it back when in shadow. Ideally, wear a base layer made from wicking fabric that can draw sweat away from the skin, followed by layers that insulate and protect from wind and moisture. “As they say, there’s no bad weather, just inappropriate clothing,” Dr. Harris says. “Take a day pack or rucksack and throw a couple of extra thermal layers in. I never head out for any hike without some ability to change as the weather changes.”
• Protect head, hands, and feet. Wear a wool hat, a thick pair of gloves or mittens, and two pairs of socks. Bring dry spares. Your boots should be waterproof and have a rugged, grippy sole.
• Wear sunscreen. You can still get a sunburn in winter, especially in places where the sun’s glare reflects off the snow.

Carry essentials to help ensure safety

• Extra food and water. Hiking in the cold takes serious energy, burning many more calories than the same activity done in summer temperatures. Pack nutrient-dense snacks such as trail mix and granola bars, which often combine nuts, dried fruit, and oats to provide needed protein, fat, and calories. It’s also key to stay hydrated to keep your core temperature normal. Bonus points for bringing a warm drink in a thermos to warm your core if you’re chilled.
• First aid kit. Bandages for slips or scrapes on the trail and heat-reflecting blankets to cover someone showing signs of hypothermia are wise. Even in above-freezing temperatures, hypothermia is possible. Watch for signs such as shivering, confusion, exhaustion, or slurring words, and seek immediate help.
• Light source. Time your hike so you’re not on the trail in darkness. But bring a light source in case you get stuck. “A flashlight or headlamp is pretty darn useful if you’re hiking anywhere near the edges of daylight,” Harris says.
• Phone, map, compass, or GPS device plus extra batteries. Don’t rely on your phone for GPS tracking, but fully charge it in case you need to reach someone quickly. “Make sure that you have the technology and skill set to be able to navigate on- or off-trail,” Harris says, “and that you have a means of outside communication, especially if you’re in a large, mixed group.”

News flash: What we eat can play a pivotal role in warding off — or treating — disease and enhancing quality of life. You may already believe this, and certainly mounting evidence supports that idea. But on the cluttered shelf of diets claiming top health benefits, which one ranks as the absolute best?

That’s a trick question. In fact, there is no single best diet. A good diet for me may be different from what’s best for you. And for either of us, there may be several good choices with no clear winner.

How can you choose the right diet for you?

When thinking about what diet might be best for you, ask yourself:

• What goals are most important? A goal might be weight loss, improved health, avoiding disease, or something else.
• How do you define “best”? For some people, best means the diet with the highest number of health benefits. For others, it may focus on one specific health benefit, such as lowering cholesterol. Still other people may prefer a diet that delivers the greatest benefit for the lowest cost. Or a diet that is healthy and also easy to stick with.
• What health problems do you have? One diet may have an advantage over another depending on whether you have cancer, cardiovascular disease, diabetes, or none of these.
• Which foods do you like best? Your tastes, culture, and location may shape your dietary preferences, and powerfully affect how likely you are to stick with a specific diet.

Which diets are high in health benefits?

Two very well studied diets demonstrate clear benefit, including lowering risk for heart disease and stroke and reducing high blood pressure: the Mediterranean diet and the DASH diet.

But the portfolio diet may be as good as or better than these plans, at least for combatting cardiovascular disease that contributes to clogged blood vessels, heart attacks, and stroke. What? You’ve never heard of the portfolio diet? You’re not alone.

What is the portfolio diet?

Just as a financial advisor may recommend having a diverse investment portfolio — not just stocks, not just bonds — the portfolio diet follows suit. This largely plant-based diet focuses on diverse foods and food groups proven to lower harmful blood lipids, including LDL (so-called bad cholesterol) and triglycerides.

If you choose to follow this eating pattern, you simply need to learn which foods have a healthy effect on blood lipids and choose them in place of other foods. For some people, this only requires small tweaks to embrace certain foods while downplaying other choices. Or it may call for a bigger upheaval of longtime eating patterns.

Which foods are encouraged in the portfolio diet?

Below are the basics. Eating more of these foods regularly may help lower levels of harmful blood lipids:

• plant-based proteins such as soy, beans, tofu, peas, nuts, and seeds
• high-fiber foods such as oats, barley, berries, apples, and citrus fruit; other examples include bran, berries, okra, and eggplant
• phytosterols, which are a natural compound in plant-based foods such as whole grains, fruits, vegetables, and nuts (other sources are foods fortified with phytosterols or dietary supplements)
• plant-based oils high in monounsaturated fat such as olive oil, avocado oil, safflower oil, and peanut oil.

See? Some of your favorite foods make the cut. That’s a major strength of this approach: the list of recommended foods is long. So, it’s likely that you’re already eating and enjoying some of the recommended foods.

Which foods are not part of the portfolio diet?

It’s worth highlighting foods that are not on this list, such as

• red meat
• highly processed foods
• refined grains and added sugar, which may contribute to chronic inflammation
• butter, cream, and other dairy products high in saturated fat and cholesterol.

What can the portfolio diet do for you?

Researchers have shown that the portfolio diet can improve blood lipids. But can it also lower the risk of heart attack, stroke, and other cardiovascular problems?

Yes, according to a 2023 study published in Circulation. More than nearly 17,000 people kept careful food diaries for 30 years. Those who most closely followed the portfolio diet, compared with those who followed it the least, were more likely to have favorable lipids and inflammation. They were also 14% less likely to have a heart attack, and 14% less likely to have a stroke.

This was true even after accounting for factors that could affect cardiovascular disease risk, such as taking cholesterol-lowering medications, exercise, smoking, or having diabetes or a family history of cardiovascular disease.

Because this was an observational study, it can’t conclusively prove that the portfolio diet, rather than another factor, was responsible for the observed cardiovascular benefits. And we don’t know how much benefit came from reducing or eliminating certain types of foods, rather than from the specific foods eaten.

Does the portfolio diet help people lose weight or deliver other health advantages?

What about the portfolio diet for weight loss? Although some people lose weight on the portfolio diet, it’s not billed as a weight-loss diet. Understanding its potential benefit for other conditions such as obesity, cognitive decline, diabetes, and cancer awaits further research.

Go beyond diet to boost health

Of course, diet is not the only way to improve cardiovascular health and your overall health. You’ll stay healthier by

• not smoking
• getting regular exercise
• maintaining a healthy blood pressure and weight
• preventing diabetes when possible, or getting good medical care to treat it if necessary
• taking prescribed medications such as cholesterol-lowering drugs.

The bottom line

It’s probably best to move past the idea of there being a single best diet. The overall pattern of your diet and your portion sizes are probably more important. For most people, it’s also a good idea to move away from restrictive diets that are nearly impossible to stick with and toward healthier overall eating patterns. The portfolio diet checks both those boxes.

There’s a lot of overlap between the portfolio diet and other healthy diets. So, no one should be suggesting it’s the best diet ever. But if you’re trying to eat healthier, it’s a great place to start.
