3 ways to create community and counter loneliness

Loneliness is complicated. You can feel lonely when you lack friends and miss companionship, or when you’re surrounded by people — even friends and family.

Either way, loneliness can have devastating health effects. It boosts risk for coronary artery disease, stroke, depression, high blood pressure, declining thinking skills, inability to perform daily living tasks, and even an early death. The remedy? Below we offer three ways to ease loneliness and add happiness by helping you expand your social network.

Taking the first steps

Not all loneliness can be solved by seeking out people. Loneliness that occurs despite relationships may require talk therapy and a journey that looks inward.

Reducing loneliness caused by a lack of relationships is more of an outward journey to make new friends. “That’s a challenge as we get older, because people are often established in their social groups and aren’t as available as they might have been in a different phase of life. So you have to be more entrepreneurial and work harder to make friends than you once did,” says Dr. Jacqueline Olds, a psychiatrist at Harvard-affiliated McLean Hospital and the coauthor of two books on loneliness.

Trying these strategies can help.

1. Seek like-minded souls

Being around people who share your interests gives you a head start on making friends: you already have something in common.

Start by considering your interests. Are you a voracious reader, a history lover, a movie aficionado, a gardener, a foodie, a puppy parent, or an athlete? Are you passionate about a cause, your community, or your heritage? Do you collect things? Do you love classic cars? Do you enjoy sprucing up old furniture? Maybe you want to learn something new, like how to cook Chinese food or speak another language. Search for online groups, in-person clubs, volunteer opportunities, or classes that match any of your interests or things you’d like to try.

Once you join a group, you’ll need to take part in it regularly to build bonds. If you can gather in person, it’s even better. “The part of our brain involved in social connection is stimulated by all five senses. When you’re with someone in the same room, you get a much stronger set of stimuli than you do by watching them on an electronic screen,” Dr. Olds says.

2. Create opportunities

If joining someone else’s group is unappealing, start your own. Host gatherings at your place or elsewhere. “All it takes is three people. You can say, ‘Let’s read books or talk about a TV show or have a dinner group on a regular basis,'” Dr. Olds says.

Other ideas for gatherings — either weekly or monthly — include:

  • game nights
  • trivia nights
  • hikes in interesting parks
  • beach walks
  • bird-watching expeditions
  • running or cycling
  • meditation
  • museum visits
  • cooking
  • knitting, sewing, or crafting
  • shopping
  • day trips to nearby towns
  • jewelry making
  • collector show-and-tell (comic books, antique dolls, baseball cards).

The people you invite don’t have to be dear friends; they can just be people you’d like to get to know better — perhaps neighbors or work acquaintances.

If they’re interested in a regular gathering, pin down dates and times. Otherwise, the idea might stay stuck in the talking stages. “Don’t be timid. Say, ‘Let’s get our calendars out and get this scheduled,'” Dr. Olds says.

3. Brush up your social skills

Sometimes we’re rusty in surface social graces that help build deeper connections. “It makes a huge difference when you can be enthusiastic rather than just sitting there and hoping someone will realize how interesting you are,” Dr. Olds says.

Tips to practice:

  • Smile more. Smiling is welcoming, inviting, and hospitable to others.
  • Be engaging. Prepare a few topics to talk about or questions to ask — perhaps about the news or the reason you’ve gathered (if it’s a seminar, for example, ask how long someone has been interested in the subject). Or look for a conversation starter. “Maybe the person is wearing a pretty brooch. Ask if there’s a story behind it,” Dr. Olds suggests.
  • Be a good listener. “Listen in a way that someone realizes you’re paying attention. Hold their gaze, nod your head or say ‘Mm hmm’ as they’re talking so you give feedback. Assume everyone in the world is just yearning for your feedback,” Dr. Olds says.
  • Ask follow-up questions. Don’t ignore signals that someone has interesting stories to tell. “If they allude to something, your job is to look fascinated and ask if they can tell you more. They’re dropping crumbs on a path to a deeper exchange,” Dr. Olds notes.

Even chats that don’t lead to friendships can be enriching. A 2022 study found that people who had the most diverse portfolios of social interactions — exchanges with strangers, acquaintances, friends, or family members — were much happier than those with the least diverse social portfolios.

Ultimately, a wide variety of interactions contributes to well-being, whether you’re talking to the cashier at the supermarket, a neighbor, an old friend, or a new one. And all of these connections combined may go a long way toward helping you feel less lonely.

When replenishing fluids, does milk beat water?

6 colorful or black panels with a brightly colored or black jug on each

Driving along the freeway recently, a billboard caught my eye. In bold letters it proclaimed:

Milk hydrates better than water.

Wait, could this be true? And if so, should I be rehydrating with milk after a workout? And should we all have milk, rather than water, in our water bottles?

What’s behind the claim?

Unsurprisingly, the ad is sponsored by the milk industry. And while I’d never heard this claim before, the studies behind the idea aren’t particularly new or compelling. The website supporting this ad cites three small studies dating back more than a decade:

  • A 2007 study enrolled 11 volunteers (five men, six women) who exercised until they were markedly dehydrated on several occasions. Each time they rehydrated with a different drink, and their urine output was measured over the following five hours. After drinking milk, the study volunteers produced less urine (and therefore retained more fluid) than with water or a sports drink (Powerade). Therefore, milk was considered to provide better hydration.
  • A study published in 2016 described seven men with marked dehydration following exercise who drank fat-free milk, water, or Powerade. The results were similar.
  • A 2016 study enrolled 72 healthy, well-hydrated men who drank various fluids and then had their urine production measured over the next four hours. The drinks used in this study were water, whole milk, skim milk, beer, Dioralyte (an oral rehydration solution used after fluid loss from diarrhea), tea, coffee, diet cola, regular cola, orange juice, and Powerade. The researchers found that fluid retention was best after drinking either type of milk or the oral rehydration solution; results for the other drinks were similar to water.

Sounds like milk is a winner, right? Maybe. But there are other things to consider.

The study details matter

The findings of these studies aren’t definitive. As with all research, there are important limitations. For example:

  • The small number of participants in these studies means that just a few people could have an outsized impact on the results.
  • Two of the three studies involved significant dehydration by intensely exercising in a warm environment, leading to several pounds of fluid loss. Therefore, the results may not apply to people engaged in more typical daily activities or workouts. In addition, the studies equated better hydration with less urine production in the hours after drinking various fluids. This is only one way to define hydration, and not clearly the best one.
  • The advantage of milk reported in these studies may be too small or too temporary to matter much. For example, in the study of 72 people, milk drinkers produced about 37 ounces of urine over four hours while water drinkers produced 47 ounces. Does the 10-ounce difference have a meaningful health impact? If the study participants had been monitored for a longer period, would this difference disappear?
  • The amount of milk consumed in the study of seven men would contain more than 1,000 calories. That may be acceptable for an elite athlete after hours of intensive exercise in the heat, but counterproductive and costly for someone working out for 30 minutes to help maintain or lose weight. Tap water is free and has no calories!

Hyping hydration: Many claims, little evidence

The billboard promoting milk reflects our relatively recent focus on hydration for health. This is promoted — or perhaps created — by advertisers selling sports drinks, energy drinks and, yes, water bottles. But does drinking “plenty of water” translate to weight loss, athletic performance, and glowing appearance? Does monitoring urine color (darker could indicate dehydration) and downing the oft-recommended eight glasses of water daily make a difference in our health? On the strength of evidence offered so far, I’m not convinced.

But wait, there’s more! Emotional support water bottles, a trend popularized recently in Australia, offer one part public expression of your commitment to health and one part security blanket. (Yes, it’s a thing: #emotionalsupportwaterbottle has more than 80 million views on TikTok.) And then there’s intravenous hydration on demand for healthy (and often wealthy) people convinced that intravenous fluids will improve their looks, relieve their hangovers, help with jet lag, or remedy and prevent an assortment of other ailments.

Is this focus on hydration actually helpful?

Before water bottles were everywhere and monitoring fluid intake became commonplace, medically important dehydration wasn’t a problem for most healthy people who were not rapidly losing fluids due to heat, intense exercise, diarrhea, or the like.

The fact is, drinking when thirsty is a sound strategy for most of us. And while there are important exceptions noted below, you probably don’t need fluids at hand at all times or to closely monitor daily fluid intake to be healthy. There are far more important health concerns than whether you drink eight glasses of water each day.

When is dehydration a serious problem?

Weather, exercise, or illness can make dehydration a major problem. Particularly susceptible are people who work or exercise outside in hot and humid environments, those at the extremes of age, people experiencing significant fluid loss (as with a diarrheal illness), and those without reliable access to fluids. If significant dehydration occurs, replacing lost fluids is critically important, and may even require a medical setting where intravenous fluids can be provided quickly.

The bottom line

Despite the claims of milk ads and the iffy studies justifying them, the idea of replacing water with milk for rehydration may not convince everyone: the taste, consistency, and extra calories of milk may be hard to get past.

As for me, until there’s more convincing evidence of an actual health advantage of milk over water for routine hydration, I’ll stick with water. But I’ll forego the water bottle.

Slowing down racing thoughts

Two black heads outlined against a yellow background; one showing white loops of tangles and the other showing neat white coils to indicate upsetting thoughts and calmer thoughts Everyone has moments when their brain suddenly goes haywire. They repeatedly fixate on the same thought, like being stuck on a hamster wheel. Or their thoughts aimlessly bounce from one random topic to the next like a pinball.

People often refer to these thought patterns as racing thoughts, and the most common cause is anxiety, says Fairlee Fabrett, PhD, a psychologist at Harvard-affiliated McLean Hospital.

“People who struggle with racing thoughts are constantly worried about what needs to be done, what hasn’t been done, and what is next,” says Fabrett. “Or they obsess about past, present, or future situations.” For example, you replay a conversation with different versions of dialogue, ruminate about an upcoming meeting with your boss or medical appointment, or worry about an unlikely doomsday scenario.

“When racing thoughts take over your mind you can’t stay focused, and you feel trapped, which makes you even more anxious and stressed, and the cycle continues,” says Fabrett.

Breaking the cycle of anxiety and racing thoughts

How can you break this cycle and keep racing thoughts from controlling you? Here are five strategies to try.

Give yourself permission. Racing thoughts are often made worse by the anxiety over having racing thoughts. To escape this, give yourself permission to experience them. “Acknowledge that racing thoughts are just noise, it is what our minds sometimes do, and that’s okay,” says Fabrett. “This gives you a sense of control so you don’t feel helpless. When you put racing thoughts in their proper context, they feel less threatening and easier to manage.”

Get mindful. Practicing mindfulness can help change your thought patterns. For instance, try counting your breaths. Close your eyes and count to yourself as you take slow, steady breaths: count one on the inhale, two on the exhale, etc. When you reach 10, start over and repeat the process until you calm down. “This is also a great remedy before sleep when most people’s minds begin to ruminate,” says Fabrett. Also, practice this breath work at times when your thoughts are not racing, so you will have the skill when you need it.

Distract yourself. You can sometimes break the cycle by distracting your mind. “As soon as you notice yourself worrying again or thinking about things over and over, make an internal comment to yourself, like ‘here I go again, with my list of thoughts that never ends,” says Fabrett. Then make a conscious decision to do something else, like reading, listening to music, or calling a friend.

Get moving. It sounds like token health advice — exercise more — but movement is helpful for defusing anxiety. For instance, when an episode of racing thoughts strikes, do a set of push-ups, 10 jumping jacks, take a five-minute walk, or do household chores. “These not only help break the cycle of racing thoughts but give your mind something else to focus on,” says Fabrett. Also, try to build regular exercise into your life as well as these short bursts of activity. That can help relieve anxiety and stress.

Schedule worry time. Sometimes it’s best to let racing thoughts run their course; otherwise, they may linger indefinitely. To do this, schedule worry time. When anxious racing thoughts occur, recognize them, but tell yourself that now is not worry time and you will deal with them later. Then at a fixed time of your choosing, do nothing but explore those thoughts and work through them. For example, write down the thoughts that come to mind without editing, including all the worst-case scenarios you can think of.

“You can also talk about them aloud and ask what makes you nervous and why,” says Fabrett. “This allows you to confront your anxiety head-on, but on your schedule without taking away from other activities,” says Fabrett. Set a limit to worry time, like 10 to 20 minutes. When the time is up, you move on.

If racing thoughts regularly affect your life or interfere with sleep, talk to your doctor or a mental health professional. “Frequent racing thoughts may be related to anxiety disorders, attention deficit hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD), trauma, or other mental health issues that need exploring,” says Fabrett.

Helping children who are neurodiverse build friendships

Three children with their bikes in a park with large green-leafed trees; the children, who are neurodiverse, are wearing helmets and grouped in a friendly way

Making friends and finding social opportunities can sometimes be difficult, particularly for children with neurodevelopmental disabilities, such as autism spectrum disorder, attention deficit hyperactivity disorder, or an intellectual disability. Here’s what parents can do to help.

Building inclusive communities

Friendships and social connections are an important aspect of our lives. They provide a sense of belonging and allow people to be included in their communities.

People with neurodevelopmental disabilities may communicate, learn, and behave differently. Sometimes these differences make it harder than usual to develop friendships and participate in social activities.

But parents and others can help create more inclusive communities and opportunities to build social relationships, especially for people with neurodiverse abilities.

Below are some tips and strategies to help children learn and develop the social and emotional skills they need to make friends.

Practice at home: Tips for common social situations

Navigating social settings and making friends involve many skills you can practice with children at home.

  • Greetings and questions. Make a habit of practicing greetings throughout the day. Model good listening for your child, and take turns asking and answering conversation starters like, “How are you?”
  • Calm body movements. Sometimes it can be hard for children with neurodevelopmental disabilities to keep a calm body. Have your child practice giving their body enough room and keeping personal space between themselves and others by using an arm’s-length distance.
  • Appropriate level of voice. Encourage your child to listen and match the level of your voice. Imagine your voice has a volume dial and practice turning the volume up and down.
  • Eye contact. Looking directly into someone’s eyes can be difficult, so help your child instead look at different parts of your face or practice looking at their own eyes in the mirror.
  • Reading and responding to social signals. People regularly communicate using more than just words. Social signals are the variety of ways in which we communicate through body language and facial expressions. Often this can be tricky to detect for children who are neurodiverse. Help your child recognize common social signals by asking what someone’s body or face might be saying.

Rerouting challenging behaviors to help children build friendships

Challenging behaviors may get in the way of making and keeping friends. It is important to address challenging behaviors like impulsivity and aggression through therapies and programming. Additionally, practicing the following fundamental skills can help reduce challenging behaviors.

  • Patience. Learning how to wait for a turn to play or a time to speak in a conversation is an important social skill. Practice waiting with a timer, gradually building up from 10 seconds, to one minute, to five minutes.
  • Flexibility. Help your child make compromises using first/then statements, such as, “First we play your way, then my way.” Model flexible play and redirect with new toys to show how play can evolve.
  • Communicating strong emotions.Handling strong feelings can be difficult sometimes. Practice communicating these feelings effectively either by asking for help, using an emotions board, or taking a break.

How to throw a wide net socially

Encouraging social opportunities is an important part of supporting friendships and social relationships for children with neurodevelopmental disabilities. Social spaces offer chances for children who are neurodiverse to find activities they enjoy. They are able to practice the social and emotional skills they are learning and even meet other children practicing these same skills.

  • Structure and organize play dates. Set up the environment before a play date by making a list of activities to do with a friend, then picking out of a hat which activities to do and in what order.
  • Make a list of things that are fun to do and invite others to join. Look for free or low-cost programs or events out in the community.
  • Connect with other parents of children with disabilities. Set up an activity for your children like an ice cream date, going on a walk, or a game night with adults and kids together. These encounters can give rise to repeat, planned social interactions.
  • Check out organizations in the community for children with disabilities, like Special Olympics, or recreational programs that foster inclusive environments through Unified Sports.
  • Look into facilitated recreational activities like a Lego club or pizza parties with teachers. Plan to bring a support person if needed.

Your child’s doctor or teacher may be able to suggest additional community or web-based resources designed to help families support friendships for children with neurodiverse abilities.

Why eat lower on the seafood chain?

A white plate with fresh silvery sardines with sliced lemon, parsley, garlic cloves, and olive at the ready to cook

Many health-conscious consumers have already cut back on hamburgers, steaks, and deli meats, often by swapping in poultry or seafood. Those protein sources are better than beef, and not just because they’re linked to a lower risk of heart disease, diabetes, and cancer. Chicken and fish are also better for the environment, as their production uses less land and other resources and generates fewer greenhouse gas emissions.

And choosing seafood that’s lower on the food chain — namely, small fish such as herring and sardines and bivalves such as clams and oysters — can amp up those benefits. “It’s much better for your health and the environment when you replace terrestrial food sources — especially red meat — with aquatic food sources,” says Christopher Golden, assistant professor of nutrition and planetary health at the Harvard T.H. Chan School of Public Health. But instead of popular seafood choices such as farmed salmon or canned tuna, consider mackerel or sardines, he suggests.

Why eat small fish?

Anchovies, herring, mackerel, and sardines are all excellent sources of protein, micronutrients like iron, zinc, and vitamin B12, and heart-healthy omega-3 fatty acids, which may help ease inflammation within the body and promote a better balance of blood lipids. And because you often eat the entire fish (including the tiny bones), small fish are also rich in calcium and vitamin D, says Golden. (Mackerel is an exception: cooked mackerel bones are too sharp or tough to eat, although canned mackerel bones are fine to eat).

Small fish are also less likely to contain contaminants such as mercury and polychlorinated biphenyls (PCBs) compared with large species like tuna and swordfish. Those and other large fish feed on smaller fish, which concentrates the toxins.

It's also more environmentally friendly to eat small fish directly instead of using them to make fish meal, which is often fed to farmed salmon, pork, and poultry. Feed for those animals also includes grains that require land, water, pesticides, and energy to produce, just as grain fed to cattle does, Golden points out. The good news is that increasingly, salmon farming has begun using less fish meal, and some companies have created highly nutritious feeds that don’t require fish meal at all.

Small fish in the Mediterranean diet

The traditional Mediterranean diet, widely considered the best diet for heart health, highlights small fish such as fresh sardines and anchovies, says Golden. Canned versions of these species, which are widely available and less expensive than fresh, are a good option. However, most canned anchovies are salt-cured and therefore high in sodium, which can raise blood pressure.

Sardines packed in water or olive oil can be

  • served on crackers or crusty, toasted bread with a squeeze of lemon
  • prepared like tuna salad for a sandwich filling
  • added to a Greek salad
  • tossed with pasta, either added to tomato sauce or with lemon, capers, and red pepper flakes.

Golden is particularly fond of pickled herring, which you can often find in jars in supermarkets, or even make yourself; here’s his favorite recipe.

Bivalve benefits

Bivalves are two-shelled aquatic creatures that include clams, oysters, mussels, and scallops. Also known as mollusks, they’re good sources of protein but are quite low in fat, so they aren’t as rich in omega-3’s as small, fatty fish. However, bivalves contain several micronutrients, especially zinc and vitamin B12. Zinc contributes to a healthy immune system, and vitamin B12 helps form red blood cells that carry oxygen and keep nerves throughout the body healthy. While most Americans get enough B12, some may not.

And from a planetary health perspective, bivalves are among the best sources of animal-based protein. “Bivalves can be ‘nature positive’ because they don’t require feed and they filter and clean up water,” says Golden.

Be aware, however, that bivalves can become contaminated from runoff, bacteria, viruses, or chemicals in the water. So be sure to follow FDA advice about buying and preparing seafood safely.

Although we tend to think of coastal cities as the best places to find seafood, it’s available throughout the United States. For less-common varieties, try larger Asian markets, which often carry a wide variety of fish and bivalves, Golden suggests.

Aquatic plant foods

You can even go one step further down the aquatic food chain by eating aquatic plant foods such as seaweed and kelp. If you like sushi, you’ve probably had nori, the flat sheets of seaweed used to make sushi rolls. You can also find seaweed snacks in Asian and many mainstream grocery stores. The truly adventurous may want to try kelp jerky or a kelp burger, both sold online.

Nutrients in seaweed vary quite a bit, depending on species (kelp is one type of brown seaweed; there are also numerous green and red species). But seaweed is low in calories, is a good source of fiber, and also contains iodine, a mineral required to make thyroid hormones. Similar to terrestrial vegetables, seaweeds contain a range of other minerals and vitamins. For now, aquatic plant foods remain fringe products here in the United States, but they may become more mainstream in the future, according to Golden.

Drug recalls are common

Multicolored pills, tablets, and gel medicines spilling onto a bright yellow background and surrounded by emptied silver blister packs for medications

Scientific advances have brought us scores of new drugs in recent years. In the US, one major agency — the FDA — is responsible for making sure that the drugs they approve are safe and effective. Yet there were more than 14,000 drug recalls in the last 10 years, according to FDA statistics. That averages out to nearly four drug recalls a day!

Why are drug recalls so common, and how can you maximize safety when taking the medicines you need?

Why do so many drug recalls occur?

The FDA approves prescription drugs if research shows a medicine is safe and effective. Usually the risks are well known by the time approval is granted. For over-the-counter drugs, the bar is lower: proof that they work is not required, but the FDA still maintains oversight for safety.

Drug recalls are common because:

  • Rare side effects may be missed in clinical trials. Studies leading to drug approval might have hundreds or thousands of study subjects. But a rare problem may not be detected until tens of thousands of people have taken a drug.
  • Study subjects tend to be healthier than the general population. When you’re trying to figure out if a drug works, the chances of success are higher and reliability of results is greater if study subjects are healthy. Once a drug is approved, people taking it may be older, less healthy, or taking multiple drugs for health issues.
  • Problems during or after manufacturing can make a safe drug harmful. Examples include bacterial contamination, incorrect labeling, and improper storage.
  • Bad behavior by drug makers may affect drug safety. For example, multiple over-the-counter supplements marketed for male sexual performance were recalled in recent years because they were laced with prescription drugs for erectile dysfunction.

Are most drug recalls high-risk?

Fewer than one in 10 poses a serious health risk. The FDA grades risk severity for recalls as follows:

  • Class I is dangerous and poses a serious health risk (a hand sanitizer contaminated with methanol)
  • Class II might cause a temporary or slight risk of serious harm (a diabetes medicine stored at the wrong temperature)
  • Class III is unlikely to cause any harm to health, but there is a violation of FDA requirements (an ointment for dermatitis in damaged tubes).

Between 80% and 90% of drug recalls are Class II.

In 2022, 6% of recalls were Class 1, 86% were Class II, and 7% were Class III.

How do drug recalls happen?

The FDA inspects drug manufacturing facilities every two to three years. The agency also tests thousands of drugs each year.

Problems spotted during inspections, concerns identified by drug makers, or problems reported by patients or health care professionals can prompt a recall. The FDA then assigns a risk classification, supervises actions taken by the drug maker to remedy the problem, and monitors the product to make sure the problem is eliminated.

Drug recalls in the US are almost always voluntary. That means the drug maker acknowledges the problem and takes corrective action rather than waiting for a possible mandate from the FDA.

How can you stay informed about medicines you use?

Here are some practical measures to take:

  • Sign up to receive texts or emails about recalls, market withdrawals, and safety alerts from the FDA.
  • When filling prescriptions, take a good look at your medicine. Pills should not be discolored or crumbling, or have an unusual odor. If your prescription hasn’t changed, a refill should look similar to what you’ve taken in the past. If you suspect a problem, contact your pharmacist or the health care professional who prescribed it. And if you do confirm a problem, you can report it to the FDA.
  • If you learn of a recall for a drug you take, check the lot number on the package to see if your medication is affected. If the risk is classified as high (Class I), contact your doctor right away for advice. For many recalled drugs, there are safe and effective alternatives.
  • A recall notice will tell you if the medicine can be replaced or if you can be reimbursed. If you are instructed to dispose of medication, do so safely.

Another way to limit your potential exposure to recalled drugs is to take fewer drugs. Review your medication list with your doctor regularly and take only what you truly need.

The bottom line

News on drug recalls may not inspire confidence. It might make you wonder if the drugs you take are safe. In general, yes: the vast majority of medicines on the market have an excellent safety profile. But with more than 1,000 drug recalls every year, there’s plenty of room for improvement by drug makers and good reason to encourage better regulation of the industry.

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.

Prostate cancer in transgender women

The transgender population is steadily increasing. Last year, investigators reported that 1.3% of people between the ages of 18 and 24 in the United States identify as transgender, compared to 0.55% of the country’s older adults. This trend has implications for public health, and one issue in particular concerns the risk of prostate cancer in transgender women.

Because removing the prostate can lead to urinary incontinence and other complications, doctors leave the gland in place when initiating hormonal treatments to induce female sex characteristics in transitioning people. This process, which is called feminizing or gender-affirming hormonal therapy (GAHT), relies on medications and surgery to block testosterone, a male sex hormone. Prostate cancer is fueled by testosterone, and therefore GAHT lowers overall risks for the disease. But transgender women can still develop prostate cancer in ways that remain poorly understood, according to the authors of a new paper.

“More individuals are openly identifying as transgender, particularly as advances are made in reducing the discrimination and marginalization that this group has faced,” says Dr. Farnoosh Nik-Ahd, a urologist at the University of California, San Francisco, and the paper’s first author. “Thus, it’s important to understand their health outcomes and how best to care for this population.”

Dr. Nik-Ahd and her colleagues wanted better insights into prostate cancer incidence and screening rates among transgender women, so they performed a comprehensive review of the literature that generated some notable findings. One is that that the prevalence of GAHT in the transgender population is still unknown. Some studies put the figure at roughly one in every 12,000 to 13,000 people who identify as transgender. But this is likely an underestimate, the authors claim, and it’s not broken out by sex.

Questions over GAHT

Similarly, little is known about the impact of GAHT on the likelihood of developing prostate cancer, the team reported. Prostate cancer rates do appear to be lower among transgender women than they are among cisgender men (men whose gender identify matches their sex at birth). For instance, one study found just a single case of prostate cancer among 2,306 transgender women receiving routine health care at a clinic in Amsterdam, Holland, between 1975 and 2006. Another study, also from Holland, detected six cases of prostate cancer among 2,281 transgender women over 17 years, which again is less than the comparable rate among cisgender men.

But the interpretation of these rates is limited by the fact that transgender women often experience barriers to care. Nearly a third of them live in poverty, and many avoid the health system for fear of mistreatment. Some scientists suspect that estrogen given during GAHT may somehow contribute to prostate cancer development when given over long durations. However, more confirmatory evidence is needed. Worryingly, one study found that survival among transgender women with prostate cancer is worse than it is in cisgender men with the disease, yet that research lacked data on GAHT use.

Interpreting PSA values for specific populations

Dr. Nik-Ahd’s team was especially concerned about the lack of guideline recommendations for prostate-specific antigen (PSA) screening in the transgender population. None of the available guidelines worldwide mention transgender women, and the PSA cutoff of 4 nanograms per milliliter (ng/mL) of blood — which raises suspicions for prostate cancer — is specific to cisgender men. PSA levels ordinarily plummet in people taking GAHT, so the limit for what’s considered normal in transgender women should be capped at 1.0 ng/mL, the researchers propose. In the absence of more specific guidance, they also recommend that people meeting age criteria for PSA screening get tested before starting on GAHT, in order to obtain a baseline value.

Many doctors are already familiar with other common drugs that alter PSA values — in this case with screening implications for cisgender men, points out Dr. Heidi Rayala, a urologist affiliated with Beth Israel Deaconess Medical Center in Boston, and a member of the Harvard Medical School Annual Report on Prostate Diseases editorial board. For instance, PSA values drop by half in men taking finasteride or dutasteride for hair loss (or to shrink an enlarged prostate). “Doctors take extra care when interpreting PSA in cisgender men who take these drugs,” she says. “The same care needs to be taken in interpreting PSA values in transgender women. And there needs to be broader education on this topic for both primary care doctors as well as the transgender community.

Dr. Nik-Ahd agrees. “Future research should aim to understand baseline PSA values for those on gender-affirming hormones, and to understand how to navigate some of the psychosocial barriers around PSA screening so as to not stigmatize transgender patients,” she says.

Save the trees, prevent the sneeze

photo of a man sitting on the ground with his back against a tree holding a tissue to his face and blowing his nose; ground is covered in leaves indicating fall season

When I worked at Greenpeace for five years before I attended medical school, a popular slogan was, “Think globally, act locally.” As I write this blog about climate change and hay fever, I wonder if wiping off my computer that I’ve just sneezed all over due to my seasonal allergies counts as abiding by this aphorism? (Can you clean a computer screen with a tissue?)

Come to think of it, my allergies do seem to be worse in recent years. So do those of my patients. It seems as if I’m prescribing nasal steroids and antihistamines, recommending over-the-counter eye drops, and discussing ways to avoid allergens much more frequently than in the past. Are people more stressed out, working harder, sleeping less, and thus more susceptible to allergies? Or, are the allergies themselves actually worse? Could the worsening of climate change explain why the rates of allergies and asthma have been climbing steadily over the last several decades?

There’s more pollen and a longer pollen season

Seasonal allergies tend to be caused disproportionately by trees in the spring, grasses in the summer, and ragweed in the fall. The lengthening interval of “frost-free days” (the time from the last frost in the spring to the first frost in the fall) allows more time for people to become sensitized to the pollen — the first stage in developing allergies — as well as to then become allergic to it. No wonder so many more of my patients have been complaining of itchy eyes, runny nose, and wheezing.

In many places in the United States, due to climate change, spring is now starting earlier and fall is ending later, which, yearly, allows more time for plants and trees to grow, flower, and produce pollen. This leads to a longer allergy season. According to a study at Rutgers University, from the 1990s until 2010, pollen season started in the contiguous United States on average three days earlier, and there was a 40% increase in the annual total of daily airborne pollen. More recent research in North America shows rising concentrations of sneeze-inducing pollens and lengthening pollen seasons from 1990 to 2018, largely driven by climate change.

Climate change is increasing the potency of pollen

In addition to longer allergy seasons, allergy sufferers have other things to fret about with climate change. When exposed to increased levels of carbon dioxide, plants grow to a larger size and produce more pollen. Some studies have shown that ragweed pollen, a main culprit of allergies for many people, becomes up to 1.7 times more potent under conditions of higher carbon dioxide. With warming climates, the geographic distribution of pollen-producing plants is expanding as well; for example, due to warmer temperatures, ragweed species can now inhabit climates that were formerly inhospitable.

Other unfortunate consequences of climate change, which we are already witnessing, include coastal flooding as the arctic ice sheets melt, causing the sea levels to rise; and more extreme weather, such as storms and droughts. With the increased coastal flooding, mold outbreaks are more common, which can trigger or worsen allergic reactions and asthma. More extreme weather events, such as thunderstorms, are associated with an increase in emergency department visits for asthma attacks. (It is unclear why this is the case, but one theory suggests that the winds associated with thunderstorms kick up a tremendous amount of pollen.) Allergies and asthma are closely associated, with many people, this author included, having “allergic asthma” that is likely to worsen as climate change progresses.

So what can an allergy sufferer do?

Even as the allergic environment changes in conjunction with our climate, there are steps you can take to manage the impact of seasonal allergies and reduce sneezing and itchy eyes.

  • Work with your doctor to treat your allergies with medications such as antihistamines, nasal steroids, eye drops, and asthma medications if needed. If you take other medications that may interact with over-the-counter allergy medications such as Benadryl or Sudafed, let your doctor know.
  • Discuss with your doctor whether you would benefit from allergy testing, a referral to an allergist, or prevention methods like allergy injections or sublingual immunotherapy, which, by exposing your body in a controlled manner, slowly conditions your immune system not to respond to environmental allergens.
  • Track the local pollen count and avoid extended outdoor activities during peak pollen season, on peak pollen days. However, most doctors would agree that it isn’t healthy to cut back on exercise, hobbies, or time in nature, so this is a less than satisfying solution at best. You could plan for an indoor exercise program on high-pollen days.
  • Wash clothing and bathe or shower after being outdoors to remove pollen.
  • Close windows during peak allergy season or on windy days.
  • Wear a mask when outdoors during high pollen days, and keep car windows rolled up when driving.
  • If your house has been flooded, be on the lookout for mold. There are services that you can hire that will inspect your home for mold, and remove the mold if it is thought to be harmful.
  • Have as small a carbon footprint as possible and plant trees. Even though they are responsible for some of the pollen that many of us choke and gag on each spring, summer, and fall, trees contribute to their environment by taking in carbon dioxide and producing the oxygen we breathe, thereby improving air quality. We have to protect and plant trees, even as allergy sufferers, as climate change is arguably the biggest threat that we, as a species, now face.

Can electrical brain stimulation boost attention, memory, and more?

A brain shape against a dark background, filled with vibrant, multicolored strands of light representing brain waves

Imagine this as a morning routine that replaces your first cup of coffee:

You wake up feeling a bit foggy, so you slip on a wearable device that looks like an extra-thick headband. You turn on the power source and settle in while electrical current flows into your brain. Twenty minutes later, feeling more focused and energized, you start your busy day feeling grateful for this new technology.

If this scenario sounds strange to you, I’m with you. And yet, hype around transcranial direct current stimulation (tDCS) is growing for an expanding list of conditions such as depression, ADHD, and even Alzheimer’s disease. A recent ad for one tDCS device urges you to “elevate your performance.” But before you give this a try, read on.

What is transcranial direct current stimulation?

Brain stimulation therapies aim to activate or inhibit parts of the brain. tDCS has been around for years, but its popularity has spiked over the last decade.

tDCS devices use headgear that may look like a swim cap or headband to position electrodes against the scalp. When a power source is switched on, the electrodes deliver low levels of electrical current to the brain. A typical session lasts 20 to 30 minutes and may be repeated over days or weeks.

Three better-known brain stimulation therapies are:

  • Transcranial magnetic stimulation (TMS): A device worn over the forehead stimulates specific areas of the brain by changing nearby magnetic fields. TMS is cleared by the FDA to treat depression that hasn’t responded to standard medicines, and for obsessive-compulsive disorder.
  • Electroconvulsive therapy (ECT): An electric current flowing through electrodes placed at specific locations on the scalp causes a brief seizure while a patient is under anesthesia. In use since the late 1930s, ECT can be highly effective for severe depression that hasn’t responded to standard therapies. It uses higher levels of electrical current than tDCS. That’s why it requires close medical supervision and is generally administered in a hospital or specialized clinic.
  • Deep brain stimulation (DBS): Electrodes surgically implanted in specific areas of the brain generate electrical pulses. DBS is used to treat conditions such as Parkinson’s disease, epilepsy, or tremors that don’t improve with medicines.

What claims are made for tDCS?

The brain normally functions by sending and receiving tiny electrical signals between nerve cells. Stimulating specific regions of the brain with low levels of electricity might improve focus or memory, mood, or even dementia, according to tDCS advocates.

Some claims say tDCS can

  • improve mental clarity, focus, and memory
  • increase energy and motivation
  • relieve so-called brain fog following COVID-19, Lyme disease, or other conditions
  • reduce depression or anxiety
  • reduce cravings among smokers or people with drug addiction
  • improve symptoms of ADHD or Alzheimer’s disease.

Does tDCS work?

The jury is still out. Research suggests that tDCS holds promise for certain conditions, but techniques tested through research may differ from devices sold commercially for at-home use. For example, electrodes may be positioned more precisely over an area of the brain, and how current is delivered, session length, or number of sessions may differ.

Currently, small, short-term studies show that tDCS may benefit people with:

  • Depression: An analysis of 10 randomized trials found some participants were more likely to report fewer symptoms of depression, or remission of depression, after a course of tDCS treatment compared with sham treatment.
  • Alzheimer’s disease: A review of seven studies found that tDCS lasting 20 to 40 minutes improved memory and other cognitive measures in people with mild to moderate Alzheimer’s disease.
  • ADHD: One randomized trial of 64 adults with ADHD found improved attention after 30 minutes of tDCS daily for a month.

The FDA has not cleared tDCS for any health condition, and it is considered investigational. More research with positive results and reassuring safety data are needed before tDCS gets a thumbs-up from regulators.

That’s probably why some ads for tDCS note in fine print that it is not a medical device and is only for recreational use.

Does tDCS have downsides?

While the FDA assesses tDCS as safe for adults, there are downsides to consider. For example, treatment may cause itching, irritation, or small burns at the sites of the electrodes. Some users complain of fatigue or headache.

There are no large, long-term studies of tDCS, so overall safety is uncertain. Some experts believe at-home use raises many questions, such as how much of the brain beyond targeted areas is affected, what inconsistent approaches to tDCS use might do, and how long changes in the brain — intended or not — could last.

Very limited research has been done in children. So, the consequences for a child’s developing brain aren’t clear.

Finally, tDCS devices can be expensive (several hundred dollars or more), and generally are not covered by health insurance.

The bottom line

It’s not yet clear how tDCS should be used, or who is most likely to benefit from it. If you’re interested in pursuing tDCS, understand that there’s still a lot we don’t know.

If you’re more skeptical and risk-averse (like me), you may want to wait for more definitive research regarding its benefits and risks — and for now, stick with your morning coffee to clear your mind.
