When I took up running in college, a friend of mine scoffed at the idea. He hated running and was convinced runners were “wearing out” their joints. He liked to say he was saving his knees for his old age.

So, was he onto something? Does running really ruin your joints, as many people believe?

Runners can get arthritis, but is running the cause?

You may think the answer is obvious. Surely, years of running (pounding pavements, or even softer surfaces) could wear out your joints, much like tires wear out after you put enough miles on them. And osteoarthritis, the most common type of arthritis, usually affects older adults. In fact, it’s often described as age-related and degenerative. That sounds like a wear-and-tear sort of situation, right?

Maybe not. Sure, it’s easy to blame running when a person who runs regularly develops arthritis. But that blame may be misguided. The questions to ask are:

• Does running damage the joints and lead to arthritis?
• Does arthritis develop first and become more noticeable while running?
• Is the connection more complicated? Perhaps there’s no connection between running and arthritis for most people. But maybe those destined to develop arthritis (due to their genes, for example) get it sooner if they take up running.

Extensive research over the last several decades has investigated these questions. While the answers are still not entirely clear, we’re moving closer.

What is the relationship between running and arthritis?

Mounting evidence suggests that that running does not cause osteoarthritis, or any other joint disease.

• A study published in 2017 found that recreational runners had lower rates of hip and knee osteoarthritis (3.5%) compared with competitive runners (13.3%) and nonrunners (10.2%).
• According to a 2018 study, the rate of hip or knee arthritis among 675 marathon runners was half the rate expected within the US population.
• A 2022 analysis of 24 studies found no evidence of significant harm to the cartilage lining the knee joints on MRIs taken just after running.

These are just a few of the published medical studies on the subject. Overall, research suggests that running is an unlikely cause of arthritis — and might even be protective.

Why is it hard to study running and arthritis?

• Osteoarthritis takes many years to develop. Convincing research would require a long time, perhaps a decade or more.
• It’s impossible to perform an ideal study. The most powerful type of research study is a double-blind, randomized, controlled trial. Participants in these studies are assigned to a treatment group (perhaps taking a new drug) or a control group (often taking a placebo). Double-blind means neither researchers nor participants know which people are in the treatment group and which people are getting a placebo. When the treatment being studied is running, there’s no way to conduct this kind of trial.
• Beware the confounders. A confounder is a factor or variable you can’t account for in a study. There may be important differences between people who run and those who don’t that have nothing to do with running. For example, runners may follow a healthier diet, maintain a healthier weight, or smoke less than nonrunners. They may differ with respect to how their joints are aligned, the strength of their ligaments, or genes that direct development of the musculoskeletal system. These factors could affect the risk of arthritis and make study results hard to interpret clearly. In fact, they may explain why some studies find that running is protective.
• The effect of running may vary between people. For example, it’s possible, though not proven, that people with obesity who run regularly are at increased risk of arthritis due to the stress of excess weight on the joints.

The bottom line

Trends in recent research suggest that running does not wear out your joints. That should be reassuring for those of us who enjoy running. And if you don’t like to run, that’s fine: try to find forms of exercise that you enjoy more. Just don’t base your decision — or excuse — for not running on the idea that it will ruin your joints.

Once babies are a year old, those who have been drinking infant formula don’t need it anymore. By that age, they can and should get most of their nutritional needs met by solid foods. Drinking cow’s milk, or a fortified plant milk such as soy milk, is perfectly fine. And honestly, they don’t even need that much of it.

A 2023 report from the American Academy of Pediatrics (AAP) looked closely at what toddlers actually need for healthy growth and development — and toddler milks didn’t make the cut. Here are a few key takeaways for parents.

Is toddler formula more nutritious than milk?

No. But for some parents, it feels odd and uncomfortable to stop formula and give cow’s milk. They feel like formula is more nutritious and maybe even more easily digested. That may not be surprising: a lot of marketing money has encouraged people to think this way.

So it’s understandable that some parents turn to formulas marketed for toddlers. It’s especially understandable given the claims that formula companies make about the nutritional advantages of toddler formula. You may have seen — or bought — these products marketed purely as “follow-up formulas,” “transition formulas,” or “growing-up milks.” These formulas do not have a medical purpose. They simply help companies keep the customers they would otherwise lose once babies turn a year old.

Not only are toddler formulas unnecessary, some of them are actually worse than cow’s milk. That’s the main message shared by the AAP, which hopes to help parents understand what older infants and toddlers actually need — and see through the marketing claims.

Do some toddlers need specialized formulas?

Yes. Just to be clear, I am not talking about specialized formulas for children over 12 months who have digestive, metabolic, or other medical problems.

Are toddler formulas regulated in any way?

No. Because infant formulas must meet all the nutritional requirements of babies less than 12 months of age, they are regulated by the FDA. The FDA has requirements about what they must and must not contain, and it makes sure that the facilities where infant formulas are made are regularly inspected.

This is not true of toddler formulas. They are not regulated, and not required to prove any of the claims they make about their nutritional benefits.

What might make a toddler formula unhealthy?

Given the lack of regulation, it’s not surprising that there is wide variation in the composition of toddler formulas. But what is particularly worrisome, says the AAP, is that some of these products are actually unhealthy. They may have too little or too much protein, or have added sweeteners. These added sweeteners can build a child’s “sweet tooth” and set them on the path to obesity.

Additionally, toddler formulas are more expensive than cow’s milk, creating a financial burden for families — one that is definitely not worth it.

Is your toddler’s diet healthy?

Instead of reaching for a toddler formula, try to take a broader look at your child’s diet. Toddlers should eat from the same healthy food groups we all need. This includes

• fruits and vegetables
• whole grains
• protein (such as meat, fish, beans, and nut butters)
• dairy or dairy substitutes fortified with calcium and vitamin D.

Limit added sugars, and after age 2 try to limit less-healthy fats in the child’s diet as well. The best way to build healthy lifetime habits is to start early, and this is particularly true of nutrition.

Most people want to age in place and live at home for as long as possible: according to an AARP survey, three-quarters of people 50 and older are hoping to do so.

But managing this successfully may mean hiring outside help, such as health aides who can assist you with daily activities that have become challenging. You might wonder when exactly it will make sense to seek that service. How will you know when it’s time? What can aides do for you? What are the costs and how can you make the most of their help?

Is it time to hire in-home help?

An easy way to know if it’s time for outside help is if your health takes a sudden turn for the worse — perhaps as the result of a fall that affects your mobility. But more often, the need for professional assistance at home isn’t so obvious. It develops gradually, as certain abilities — such as cooking, cleaning, or driving — become more difficult.

Even if you’re busy, happy, and able to do your own tasks and errands now, there may come a time when the balance shifts and daily activities become challenging.

“A lot of times these observations are made by family members or friends, and they start the discussion about getting help,” says Dr. Suzanne Salamon, associate chief of gerontology at Harvard-affiliated Beth Israel Deaconess Medical Center.

Start here: Ask yourself hard questions

You don’t have to wait until family and friends urge you to get outside help. Dr. Salamon recommends that you periodically assess your abilities and how well you’re managing on your own.

For example:

• Is it harder to get in and out of the bathtub because of muscle weakness or balance problems?
• Has driving become difficult because of vision changes, arthritis, or other reasons?
• Are you keeping up with your medication regimen, or are you sometimes not sure if you’ve taken pills?
• Are cooking and cleaning becoming much more of a chore than they used to be?
• Do you find grocery shopping or errands a little overwhelming?
• Do you need help bathing or getting dressed?

Be honest about the answers, and let your needs be your guide. “You might not need a home health aide yet. Maybe you only need a cleaning service to come in every other week,” Dr. Salamon says. “But if you need more assistance, it’s probably time to hire health aides.

What do health aides do?

Health aides are professional caregivers. There are two main types of aides.

• A certified nursing assistant (CNA): This is a trained, licensed professional who can provide hands-on physical care, such as helping you get up and down from a chair or bed, bathing, dressing, feeding, brushing teeth, and using the bathroom. A CNA can also perform homemaker services, such as cooking, light housework, transportation, shopping, overseeing medication routines, or sharing meaningful activities or conversation.
• A companion: This is a registered professional who can provide homemaker services but is not trained in body mechanics and cannot provide hands-on care.

The best place to find aides is through a private duty care agency, which vets and employs the aides, and takes care of their taxes and social security withholdings.

How can you find a reliable private duty care company, and what questions should you ask? Dr. Salamon suggests asking for recommendations from friends, your doctor, local senior services, or your local Area Agency on Aging.

How much does hiring health aides cost?

Private duty care is expensive. Costs average $25 to $30 per hour, typically with a three-to-four-hour minimum per week.

Those fees add up quickly. For example, if you need help two days per week for three hours per day, you’ll pay about $600 to $720 per month.

Costs are not typically covered by Medicare, but they are often covered by Veterans benefits. And they are sometimes covered fully or partially by long-term care insurance, state or local agencies on aging, or nonprofit groups.

What might hold you back from getting help you need?

Cost is a factor, of course. Even if it isn’t, you might not jump at the chance to hire home health aides. It could be that you feel you don’t need them yet, or that you’d be uncomfortable with strangers in your home.

But the sooner you can become accustomed to having professionals assist you with parts of your care as they become challenging, the better prepared you’ll be later, when you might require much more assistance. Trying services now can set you up with contacts — and caring people — you might need to lean on more often as time goes by.

How can you get over your reluctance? “Remember that you don’t have to commit to private duty care forever. Just try it for a few hours once a week. If it doesn’t go well, consider alternatives, such as eventually moving into assisted living,” Dr. Salamon says.

How far can a few hours of in-home help go?

What can an aide accomplish if you start out with just a few hours per week? Plenty.

You might want to set up a regular routine that includes doing laundry, changing bed linens, going on a walk with you, and making a large meal that can be frozen into smaller portions. Or you might want to focus on a theme for each once-a-week visit. For example, the aide can help you do errands one week, do some light house cleaning the next week, and help you cook the week after that.

“This is your opportunity to get the help you need, whether it’s with jobs around the house or basic activities of daily living,” Dr. Salamon says. “In the long run, it’s the kind of service that will keep you living on your own longer.”

Looking for gifts to give or donate this year? Climate-conscious gifts come in many guises. They may directly support our environment, for example, or aim to reduce fossil fuel use and electronic, textile, and food waste. Or they might offer enjoyable, creative ways to connect, reuse, and recycle — and possibly even regift.

“Our purchases and choices impact our climate and planet,” notes Dr. Wynne Armand, a physician and associate director of the Massachusetts General Hospital Center for the Environment and Health. Small steps like these do help, she says, even when the complex issues of climate change leading to health-compromising pollution, extreme weather, and a stressed planet feel so large and overwhelming.

“Unquestionably, we need bold, strong leaders to seek policy changes that address these problems at a systems level. But, as individuals we can make a difference through small steps,” says Dr. Armand. “Our choices help drive cultural and market shifts that hopefully push our neighbors, businesses, and policy leaders in the right direction.”

Four climate-conscious principles for gifting

• Channel the 5 Rs.Refuse, reduce, reuse, repurpose, and only then recycle. Say no to excess. Comic sections from print newspapers or beautiful images from last year’s calendars or magazines make great envelopes and gift wrap. If you’re choosing clothes, consider buying upcycled clothing or at resale shops, as appropriate.
• Beware of greenwashing. Eco-consciousness is big business, and the benefits of what you buy may be questionable. If you have a small lawn that needs infrequent maintenance, says Dr. Armand, keeping a trusty (albeit gas-fueled) mower could be a better choice for the planet than buying an electric mower, when factoring in upstream costs of natural resources and the carbon footprint required to manufacture and ship the new — and toss out the not-so-old. (Alternatively, maybe it’s time to replant that lawn with wildflowers and vegetables?)
• Skip what’s not needed. A new backpack crafted from water bottles? Another sweater to add to a closetful? If there’s no apparent need, think twice about purchases.
• Double down on experiences and connection. Think concert tickets, museum passes, or energetic options like rock-climbing gym passes and outdoor skills classes. “Gifts of experience are great, especially for people who already have all they need. If you buy for two or try a skills swap you also get to enjoy that time together,” says Dr. Armand.

25 climate-conscious gifts

Below are 25 suggestions for climate-conscious giving intended to work with many budgets.

Small but mighty climate-conscious gifts

1. Soft, warm sweaters, thick socks, or puffer vests can help people turn down the heat, saving energy resources and money.

2. Rechargeable batteries reduce materials and packaging waste.

3. An electric kettle, induction hot plate, or toaster oven can help limit indoor pollutants from gas stoves.

4. Perfectly Good Food: A Totally Achievable Zero Waste Approach to Home Cooking aims to pare back food waste and is available online.

5. Shop local artisans and craft fairs rather than buying online.

6. Plants brighten any room and help scrub the air: choose easy-care varieties, such as succulents, colorful coleus, and some herbs.

7. Protect the natural world: birds, bees, and other insects could use your help. Consider a small bird feeder that attaches to a window, a bee house, gardening tools, or seeds for a pollinator garden of colorful flowers.

8. Donate to national or worldwide climate or environmental organizations, local green spaces, and local conservation groups.

9. Gift green bonds for companies that support renewable energy — do your research, though, because greenwashing can be an issue.

10. Secret gifter-giftee swaps with large groups save sanity and throttle back waste.

Bigger splurges on climate-conscious gifts

11. When appliances reach the end of useful life, consider replacing gas stoves, water heaters, washers, dryers, and similar items with electric versions.

12. Plan a week of nearby tours and events with friends or family instead of flights and faraway travel.

13. Gift clothes and tools to enjoy the natural world: for example, warm, waterproof clothing and hiking boots, cross-country skis or skates, good binoculars for bird-watching.

14. Composters (or a weekly composting service subscription) recycle food scraps and organic waste into soil-enriching “black gold.”

15. Electric bikes may be a boon if they reduce reliance on vehicles using fossil fuels.

16. Help fund energy-efficient heat pumps or renewable solar energy.

17. Substantial donations and sustaining donor gifts to climate-conscious organizations can help in many ways.

No-cost climate-conscious gifts

18. Offer to gather information on big-ticket items in the big splurges section, including state and federal rebates and 0% loans for heat pumps, energy-efficient furnaces, solar panels, and energy-efficient appliances.

19. Teach a skill one-on-one, such as home repair, skating, chess, training for a mud run, knitting, cooking, orienteering, or gardening, or organize skills swaps with friends.

20. Gift the human power needed to replant portions of a lawn with vegetables or pollinator plants, or make a rain garden (note: automatic download) to help divert storm water.

21. Combine a no-cost reminder of the environmental benefits of no-mow May and leave the leaves campaigns with an offer to help peel back these layers come spring.

22. Friends often want to gift one another — costly generosity that can prompt last-minute candle-buying. As an alternative, gather a small group of friends for a clothing, accessories, and candle swap of new, never-took-the-price-tag-off, nearly new, and well-loved items.

23. Offer a DIY nature or bird walk for two. Try the free Pl@ntnet and Merlin apps if you can’t tell a pin oak from a petunia or a robin from a California condor.

24. If you buy for a ton of people, buy in bulk and figure out how to parcel it out in more sustainable packaging.

25. Make dinner, fudge, or another treat with friends — not completely free, but always a great way to gather your community.

Part 1 of a two-part series on making decisions about driving as we age. Read Part 2 here. 

When my grandmother repeatedly clipped the mailbox backing out of her driveway, she always had a ready explanation: "the sun was in my eyes" or "your grandfather distracted me." Our family knew we needed to take action. But no one wanted to be the one to ask her to stop driving. She was fiercely independent, didn't agree that her driving was a problem, and didn't appreciate our concerns.

Maybe there's a similar story unfolding in your family. Or maybe you're starting to wonder about your own skills. As part one in a two-part series, this post aims to help people understand red flags to watch for, and why driving abilities change as people age. It also describes a few ways to improve impaired driving, and challenges to navigate.

A second post will address ways to strike a balance that respects dignity — and safety — while providing action plans for older drivers and their families.

How safe are older drivers on the road?

Unsafe drivers can be any age, particularly when drinking is involved. But fatal traffic accidents have risen in both young drivers and older drivers, according to data from the National Safety Council:

• Fatalities occurring in crashes involving a driver ages 15 to 20 rose nearly 10% between 2020 and 2021, accounting for 5,565 deaths.
• Among drivers 65 or older, fatalities rose 15% between 2020 and 2021, accounting for more than 8,200 deaths.

While younger drivers may be inexperienced or more likely to be distracted or reckless, older drivers often overestimate their driving abilities. That may be one reason many unsafe older drivers continue to drive despite failing driving skills.

Per mile driven, the rate of motor vehicle accidents is higher for drivers ages 80 and older than for almost every other age group, according to the Insurance Institute for Highway Safety. Only the youngest drivers have higher rates. And the rate of fatal motor vehicle accidents per mile driven is higher for drivers aged 85 and older than for every other age group.

These statistics reflect the reality that an older driver may not be the only one injured or killed in a crash — occupants in one or more vehicles may be, too. And then there are pedestrians and cyclists at risk.

Clearly, the stakes are high when any unsafe driver is on the road. For older drivers with waning driving skills, it's important to recognize the problem and understand why it's happening. The following four steps are a good start.

1. Seeing any red flags?

As people get older, driving skills may decline so slowly that it's not obvious worrisome changes are happening. Even when mishaps and near-misses occur, there are so many possible contributors — especially other drivers — that it may not be clear that the older driver was at fault.

Red flags that might mean an older person is an unsafe driver include:

• concerned comments from family or friends
• reluctance of others to ride with them
• input from other drivers (why is everyone honking at me?) or traffic authorities (why am I getting all these traffic tickets?)
• getting lost on familiar roads
• consistently driving too slowly or too fast
• unexplained dents or scratches appearing on the car
• frequent accidents or near-misses.

2. Why do driving skills tend to wane with age?

While people of advanced age can safely drive (and many do!), driving skills may wane due to:

• medical conditions, such as arthritis, neuropathy, or dementia
• medications, such as sedatives or certain antidepressants
• age-related changes in reaction time
• trouble with vision or hearing
• other physical changes related to aging, such as less flexibility or strength
• difficulty processing rapidly changing information. For example, an older driver may be more likely than a younger driver to accidentally press the gas pedal instead of the brake when needing to stop suddenly.

3. What can — and can't — be reversed to improve driving?

Some changes that impair driving can be reversed or a workaround can be found. For example, if driving is impaired due to cataracts, cataract surgery can restore vision and improve driving. If night driving is difficult, it's best to drive only during the day. If memory problems are starting to arise, it may still be possible to drive safely in more limited circumstances.

Driving problems due to advanced dementia or a major stroke affecting judgment and physical skills are much less likely to improve.

4. Accept that conversations about not driving are challenging

If there is no simple way to reverse or work around declining driving skills, accept that there will be many challenges to navigate, whether you're the older driver or a family member.

Challenges facing the driver:

• It's not easy to acknowledge declining function. Driving impairment is an unsettling milestone, an indication that the future may include further loss of abilities.
• It can feel unnecessary and unreasonable. Most older folks facing a decision about whether it's safe to continue driving were good drivers not so long ago. They may still see themselves as competent drivers, and see efforts to restrict their driving as overly cautious or demeaning.
• Denial and defensiveness are common. Even when all the signs are there, it may be tempting for a poor driver to deflect blame (for example, blaming other drivers).
• Not driving is a loss of independence. Sure, there are other ways to get around and nondrivers can certainly be independent. But few alternatives rival the independence that comes with being able to drive yourself. And, depending on where you live, public transportation or other alternatives to driving may be limited.

Challenges facing the family:

• Often, the older driver doesn't share their family's concerns about driving safety. This can lead to arguments, confrontation, and resentment.
• The safety of others is at stake. The older driver with waning skills may endanger many people besides themselves: passengers in their care, other drivers and their passengers, cyclists, and pedestrians.
• It's hard to know when the time is right. Speaking up too soon may lead to unnecessary restrictions on a loved one's favored means of transportation, not to mention family strife. Waiting too long can lead to avoidable tragedy.

Finding a path forward

As for my grandmother, none of us knew what to say. Should we try to get her to agree to stop driving entirely or let her ease into the idea over time? Maybe she could stop driving at night or limit her driving to short distances. Should we bring it to the attention of her doctor and let them direct the next steps? Or should we take an even harder step and report her to the authorities?

If you're asking similar questions — or if you're starting to wonder about your own driving abilities — you may feel strongly that it's important to respect individual preferences, dignity, and independence. Yet you also want to protect everyone from harm.

What are the best ways to strike a balance? Can you test and improve how an older driver is doing behind the wheel? Can you navigate tough conversations in ways that allow room for both independence and safety? These are the subjects to be tackled in Part 2.

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.

The holidays, as painted by idealists, are hardly the time for disagreements. They’re supposed to be filled with love, laughter, good cheer, and those tiny sparkly lights that make the mood feel festive. Unfortunately, joyous celebration often deteriorates into epic discord when family and friends gather during the season. But you don’t have to get drawn into arguments if you plan ahead and stay alert for potential triggers.

Why do we fight at the holidays?

In many ways, we are primed for holiday arguments. “It’s a stressful time. Buying gifts can lead to financial worries. The weather is colder. Days are darker. We’re trying to juggle work and get time off,” says Justin Gillis, a clinical therapist at Harvard-affiliated McLean Hospital. “The holidays can also elicit painful memories or make us face unfortunate realities in our lives, such as a lack of family or close support.”

As a result, we are often emotionally vulnerable during the holidays, Gillis says. It’s hard to manage intense feelings, express ourselves accurately, or be open and nonjudgmental.

“When we increase emotional arousal, it impacts our reasoning and subsequent behaviors. So we may be more defensive, or express ourselves in ways that result in conflict,” Gillis says.

Drinking alcohol at holiday gatherings can also fuel arguments, since alcohol lowers inhibitions and makes it harder to remain calm or maintain composure. In a 2021 survey from the American Addiction Centers, 57% of 3,400 respondents said they had at least one family member who becomes argumentative at holiday gatherings after imbibing too much.

Plan ahead to help defuse emotions and arguments

It’s challenging to control emotions in a heated moment. A bit of planning can help you avoid potential arguments or take appropriate action if angry words start flying. Here are some helpful tips.

Set a time limit. If you’re hosting the event, let your guests know in advance what time the festivities will end. If you’re attending the event, tell the host in advance when you’ll have to leave. “Stick to the plan, even if things are going well, so you can end on a high note,” Gillis says.

Ask for help. To help you rein in reactivity, ask someone you trust to give you a sign if a conversation appears to be risky or escalating. “They can chime in and ask you to do something, which is code for, ‘Back out or take a break.’ Doing that will ensure that you separate from the discussion,” Gillis says.

Schedule breaks. Think about when and how you’ll be able to take breaks during a gathering. This gives you an opportunity to check in with your emotions. “You might go into another room and take a moment to breathe deeply, volunteer to help set the table or clean up, or excuse yourself to make a phone call, even if nothing is wrong,” Gillis suggests. “These can be welcome distractions that limit the chance for conflict.”

Prepare words of deflection. If you know loved ones might ask questions that will lead to conflict, have a prepared answer and practice it. “Make a statement acknowledging the person’s feelings and letting them know it’s best for the topic to change,” Gillis says. He suggests using a version of the following statements.

• “I appreciate your thoughts, but let’s talk about something we agree on or share.”
• “I care about you, but I’m starting to feel sad and I don’t want to continue a negative conversation.”
• “I appreciate and respect your passion about this, but I don’t think I can talk about this anymore.”

How to de-escalate arguments

If you find that heated debates or arguments are brewing — or boiling over — you can still take a few steps to defuse the situation. Use the deflection statements you practiced, or excuse yourself from the conversation to go do another activity.

Other tips to keep in mind:

Don’t take the bait. Don’t answer nosy questions if you don’t want to. “Change the subject. Move the focus back onto the other person and ask how they’re doing,” Gillis says. And if someone asks a loaded question (such as, “I suppose you voted for that candidate?”), use humor if appropriate (“Let’s talk about the Bruins instead”) and change the subject or the activity.

Adjust your mindset. “We have to accept that there are perspectives we don’t like and that engaging in conflict isn’t likely to change anyone’s perspective,” Gillis says. “You can choose not to participate in an unhealthy conversation.”

Respond with kindness. “If someone is angry with you, that suggests they really care what you think. Remember that and try to maintain a compassionate stance and response,” Gillis advises.

Remember why you’re there. The goal of the gathering is celebrating, not solving painful or controversial issues. “It’s the holiday. It doesn’t have to be the day when everyone puts their cards on the table to work out problems,” Gillis says. “Make it festive and enjoyable so you can feel that you created a pleasant holiday memory together.”

Are you having a little trouble hearing conversations? If so, you’re not alone. An estimated 23% of Americans ages 12 and older have hearing loss. Although most of those people have mild hearing loss, for people ages 80 years and older, it’s more common for hearing loss to be moderate to severe than mild.

But not only is moderate to severe hearing loss disruptive to one’s life, it also makes you more likely to develop dementia. A new study helps explain why — and what you can do about it.

What did the new study look at and find?

A study published in JAMA focused on a sample of adults in the United States from the National Health and Aging Trends Study, which follows Medicare beneficiaries. The participants sampled were 70 or older.

The researchers found that about 33% of participants had normal hearing, 37% had mild hearing loss, and 30% had moderate to severe hearing loss. Dementia occurred least often among those with normal hearing (6%), more often among those with mild hearing loss (9%), and most often among those with moderate to severe hearing loss (17%). That’s a large increase in risk, particularly for those whose hearing loss is moderate to severe.

What else to know about this study

The study sample was selected to make it possible to analyze subgroups by age and apply findings to a diverse population. The sample included additional participants ages 90 years and older, and additional participants who identified as Black. Of the 2,413 total participants, 53% were ages 80 years and older, 56% were female, 19% were non-Hispanic Black, 4.5% were Hispanic, and 74% were non-Hispanic white.

Also, unlike previous research, this study looked objectively at hearing loss and dementia. Prior research had shown that hearing loss is thought to account for about 8% of all dementia cases worldwide. Exactly why the connection exists is not known.

It’s important to note that most large studies that found this link were based on questionnaires that people fill out. In other words, no one actually measured the hearing of those participating in the study to make sure that they had hearing loss — or that their hearing was really normal.

In this new study, however, the investigative team used an electronic tablet-based audiometer to evaluate participants’ hearing for four pure tone frequencies that are most important for understanding speech. So, for the first time in a large study, there was objective measurement of hearing loss.

How do hearing aids reduce the risk of dementia?

If you have hearing loss, does that mean you’re doomed to develop dementia? Not at all. This study found that those with moderate to severe hearing loss could significantly reduce their risk of dementia simply by using hearing aids.

This research helps us understand why hearing loss causes dementia. Here’s the connection:

There is increasing evidence that the more the brain is stimulated, the less likely it is that dementia will develop. When there is hearing loss, auditory stimulation is reduced. This, by itself, likely increases dementia risk. But even more important is that when an individual suffers from moderate to severe hearing loss, they are less likely to participate in social activities. Perhaps they are embarrassed about their hearing loss. Or they may simply find it unrewarding to attend a social event when they cannot hear what is going on.

It turns out that social activities are one of the best ways to stimulate the brain, as there is evidence that our brains evolved to facilitate social behavior. Given all this information, you won’t be surprised to learn that reduced social activity has been linked to cognitive decline. Thus, this new study provides additional evidence that the reason hearing loss increases the risk of dementia is because hearing loss reduces brain stimulation — both directly and through reduced social interaction.

What to do if you have hearing loss

Don’t let hearing loss raise your risk of dementia.

• Keep your ears clean. (But remember, never put anything in your ears smaller than your elbow. Ask your doctor if you’re not sure how to clean your ears.)
• If you can’t hear and you don’t have hearing aids, get them. Hearing aids now available over the counter can help many people with mild to moderate hearing loss.
• If you have hearing aids, wear them.
• If your hearing aids aren’t working, get them fixed.
• Don’t be passive — ramp up your social life and other activities.

All these things will help to reduce your risk of dementia. And you might just find that, despite some hearing loss, you’re enjoying life more.

Blood circulation is vital to our health. Our arteries deliver oxygen, energy-rich nutrients, hormones, immune cells, and other essentials throughout the body. When deliveries are cut off, organs and tissue can be irreversibly damaged within minutes.

But a second part of blood circulation is also vitally important: the return trip. After our arteries deliver the goods, our blood must return to the lungs to pick up more oxygen, stock up on nutrients, get rid of carbon dioxide, and head back to the heart to be pumped out again. In this way, blood is in continuous motion, ensuring organs and tissues get what they need while waste products are removed.

The vessels designed for the return trip are your veins. Read on for answers to questions about how veins work, what can interfere with their ability to work smoothly, and five ways to keep thousands of miles of these blood vessels healthy.

What are veins and what do they do?

Perhaps you haven't thought much about your veins. Or if you have, maybe you focused on varicose veins, those swollen, unsightly purplish vessels that may be visible just beneath the skin of the legs. Or perhaps you had a blood test and the person taking the blood had a hard time finding a "good vein." But these are just a small part of vein world.

Veins make up a network of connecting tubes throughout the human body, ranging in size from 1 mm (about the size of a pencil point) to 2 cm (about the size of a quarter), that bring blood low in oxygen back to the lungs to reload with oxygen. Then four pulmonary veins carry oxygen-rich blood from the lungs to the heart. (Fun fact: some people have three or five pulmonary veins, but most of us have four.)

Often, major veins are found alongside similarly named arteries, like a highway with cars moving in opposite directions: in the upper arm, for example, the axillary vein lies next to the axillary artery; in the kidney, the renal vein runs alongside the renal artery.

How do veins help keep blood flowing?

Let's start by picturing tiny red blood cells loaded up with oxygen. Now imagine you're a red blood cell that has just traveled from the heart through the arteries to a calf muscle of someone who is jogging. After you drop off the much-needed oxygen and pick up waste products like carbon dioxide, you need to get back to the heart — fast! — because exercising muscles need extra oxygen.

But wait. As you head back to the lungs to load up on more oxygen and release carbon dioxide, there's a steep climb straight up. How can you make it back to the lungs without help?

Fortunately, veins have tiny valves within them that allow blood to flow in only one direction. When muscles contract near larger veins, they pump blood toward the lungs. In addition, taking in a breath creates a sort of suction that pulls blood toward the lungs. Without these forces encouraging blood to flow in the right direction through the veins, blood flowing into the legs would pool there, causing dangerously high pressure and swelling.

Why are veins blue?

Actually, they aren't. People think they're blue because that's often how they appear in diagrams and illustrations. But that's just to set them apart from the bright red arteries.

The veins on the back of your hand may appear blue if you have light-colored skin. That's an illusion due to the way light is absorbed by the skin. In people with darker skin tones, veins tend to blend in more.

If you could look at veins directly, without any skin in the way, they'd appear pale because they are naturally colorless, or dark red due to the blood inside them.

What sort of problems can occur in veins?

Blood clots, varicose veins, and venous insufficiency are some of the most common health conditions affecting the veins:

• Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, blocking blood flow. This condition is potentially serious because clots in deep veins can travel to the lungs, causing a life-threatening pulmonary embolism by blocking an artery that delivers blood to part of the lungs.
• Superficial thrombophlebitis is a blood clot in a small vein just under the skin. This causes inflammation and pain.
• Varicose veins are small veins under the skin that swell and twist. While these may be harmless, they can cause pain and are occasionally complicated by blood clots.
• Venous insufficiency occurs when the valves in veins are damaged — due to aging or prior blood clots, for example. The blood flow through the veins may be impaired, leading to leg swelling, increased pressure, inflamed skin, and poor healing.

One far more rare condition goes by the impressive name of phlegmasia cerulea dolens. It is a serious complication of DVT in which the obstruction of blood flow through a deep vein leads to blocked blood flow through nearby arteries. That can cause gangrene and the need for amputation.

All of these conditions can affect circulation temporarily or in a lasting way. Treatments are aimed at restoring circulation, if possible.

Top 5 ways to improve vein health

Healthy veins help the heart, brain, and every other part of your body. Here are five ways to improve vein health, even if you already have vein disease:

• Be active. Exercise regularly and avoid prolonged standing or sitting.
• Choose healthy foods, such as those in a plant-based, heart-healthy diet.
• Maintain a healthy weight.
• Don't smoke.
• Wear compression stockings if you already have vein disease such as venous insufficiency.

And of course, seek medical care for unexplained swelling, inflammation, or ulcers on your legs, ankles, or feet.

The bottom line

Our veins are busy around the clock, shuttling blood from distant sites back to the lungs and heart, which pumps enriched blood out again. Without veins, blood circulation could not happen. They're a good example of how many parts of your amazing body are easy to overlook until something goes wrong.

Birth control pills have been safely used in the US (and sold only by prescription) for more than half a century. Just this past summer, the FDA approved Opill, the first daily contraceptive pill intended for sale over the counter. This offers many more people access to a new nonprescription option for preventing pregnancy.

Opill may be available early in 2024, although the exact date and cost are not yet known. Here’s what anyone interested — adults, parents, and teens — should know.

What is in Opill and how does it work?

Opill is a progestin-only form of birth control. That means it uses a single hormone called progestin (or norgestrel) to prevent pregnancy. It works by

• affecting ovulation so that the ovaries do not release an egg every month
• thickening cervical mucus, which blocks sperm from reaching an egg
• changing the uterine lining in ways that keep a fertilized egg from implanting.

How effective is Opill at preventing pregnancy?

It depends on how consistent you are about taking Opill:

• Perfect use means taking the pill every single day at the same time. With perfect use, Opill is 98% effective. That means that if 100 people take the medication perfectly, two or fewer people would become pregnant. Taking a pill perfectly can be difficult, though.
• Typical use averages how well a method works to prevent pregnancy when real people use it in real life. It considers that people sometimes use the pill inconsistently, like forgetting a dose or not taking it at the same time every day. With typical use, Opill is 91% effective. This means that if 100 people use Opill, but don’t take it perfectly, at least nine could become pregnant in a year.

It's also important to know that some medications make Opill less effective at preventing pregnancy. These include medicines used to treat migraines and seizures. Even though this birth control pill will be available over the counter, you should ask your health care provider if any medicines you take could make it less effective.

How do you take Opill?

• Take it once a day at the same time each day until you finish the entire pack.
• Sticking to a consistent time of day, every day, is crucial. Timing matters with progestin-only pills like Opill because this medication works by raising progestin levels. However, progestin only stays elevated for 24 hours after you take each pill. After that, the progestin level will return to normal.
• After you complete a 28-day pack, you should immediately start a new pack of pills the next day.

What happens if you forget to take a dose at the specific time or miss a dose?

• If you take the pill more than three hours late it will not be as effective at preventing pregnancy.
• Take the missed pill as soon you remember.
• You will need to use a backup birth control method such as condoms every time you have sex for the next 48 hours.

Is Opill safe for teenagers?

Opill is generally safe for most people who could get pregnant, including teenagers. There’s no evidence to suggest that safety or side effects are different in teenagers compared with adults.

Research done by the manufacturer has established the safety of Opill in people as young as 15 years old. It will be available without an age restriction.

When teens use birth control, what is the best choice for them?

There isn't a one-size-fits-all birth control method for all teenagers. The best method is the one a teen personally prefers and is committed to using consistently.

For teens who struggle with taking medication at the same time every day –– or anyone else who does –– Opill may not be the right choice. Fortunately, there are many options for preventing pregnancy, catering to individual preferences and goals.

Learn more about different contraception methods at the Center for Young Women’s Health website.

What side effects are common with Opill?

Progestin-only pills are usually associated with mild side effects. The most common side effects are:

• unexpected vaginal bleeding or spotting
• acne
• headache
• gastrointestinal symptoms such as nausea, abdominal pain, and bloating
• change in appetite.

Opill does not cause problems with getting pregnant in the future, or cause cancer. Unlike birth control pills that combine the hormones estrogen and progestin, Opill will not increase the risk of a developing a blood clot.

Will Opill cause any mood changes?

Research looking at possible effects of progestin-only pills on mood is limited, so this is unclear. We do know that most people who take hormonal birth control methods do not experience negative mood changes.

Fortunately, there are many different types of effective birth control. If one method causes you unwanted side effects, talk to your health care provider. Together, you can figure out if another type of birth control may work better for you.

Can it be used as emergency birth control?

No, it should not be used as emergency birth control.

What should you know about STIs?

This type of birth control does not protect you from sexually transmitted infections (STIs) such as syphilis, gonorrhea, or chlamydia.

You can reduce the chance of getting STIs by correctly using condoms each time you have sex. There are different types of condoms: one made for penises and one made for vaginas.

Vaccines help protect against some STIs such as hepatitis B and human papillomavirus (HPV). A medicine called PrEP can help prevent HIV. Ask your medical team for more information about the right choices for you.

When will Opill be available and what will it cost?

The timeline for availability and the cost of medication is determined by the manufacturer. At time of FDA approval, it was expected to hit shelves in early 2024. No updates have been released for the exact date or estimated cost of the medication.
