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.

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.

Headaches are very common in children and teens. In fact, more than half will suffer from headaches at some point, and by 18 years the majority of adolescents have had them. And while most headaches are part of a viral illness, some are migraines. In fact, recurring migraines affect as many as one in 10 children and teens overall.  

What should you know — and do — if you think your child or teen may be having migraines?

How early do migraines start to occur?

We don’t tend to think about migraines in children, but by age 10, one in 20 children has had a migraine. And migraines sometimes occur even earlier.

Before puberty, boys and girls are equally likely to have them. After puberty, migraines are more common in girls.

Which migraine symptoms are most common in children?

Migraines are often one-sided in adults. In children they are more likely to be felt on both sides of the head, either in both temples or both sides of the forehead.

While it’s not always easy to tell a migraine from another kind of headache, children

• often report throbbing pain
• may experience nausea and sensitivity to light and noise.

The flashing lights and other vision changes people often see as a migraine begins are less common in children. However, parents may notice that their child is more tired, irritable, or pale before a migraine begins — and takes a while to get back to normal after it ends.

What causes migraines in children?

We don’t know exactly what causes migraines. We used to think it had to do with blood flow to the brain, but that does not seem to be the case. It appears that migraines are caused by the nerves being more sensitive, and more reactive to stimulation. That stimulation could be stress, fatigue, hunger, almost anything.

Migraines run in families. In fact, most migraine sufferers have someone in the family who gets migraines too.

Can migraines be prevented?

The best way to prevent migraines is to identify and avoid triggers. The triggers are different in each person, which is why it’s a good idea to keep a headache diary.

When your child gets a headache, write down what was happening before the headache, how badly it hurt and where, what helped, and anything else about it you can think of. This helps you and your doctor see patterns that can help you understand your child’s particular triggers.

It’s a good idea to make sure your child gets enough sleep, eats regularly and healthfully, drinks water regularly, gets exercise, and manages stress. Doing this not only helps prevent migraines, but is also good for overall health!

How can you help your child ease a migraine?

When a migraine strikes, sometimes just lying down in a dark, quiet room with a cool cloth on the forehead is enough. If it’s not, ibuprofen or acetaminophen can be helpful; your doctor can tell you the best dose for your child.

It’s important not to give your child these medications more than about 14 days a month, as giving them more often can lead to rebound headaches and make everything worse!

Are there prescription medicines that can help children with migraines?

If those approaches aren’t enough, a class of medications called triptans can be helpful in stopping migraines in children ages 6 and up.

If a child experiences frequent or severe migraines, leading to missed days of school or otherwise interfering with life, doctors often use medications to prevent migraines. There are a number of different kinds, and your doctor can advise you on what would be best for your child.

Some girls get migraines around the time of their period. If that happens frequently, sometimes taking a prevention medicine around the time of menses each month can be helpful.

When to contact your doctor

If you think your child might be having migraines, you should call and make an appointment. Bring the headache diary with you. Your doctor will ask a bunch of questions, do a physical examination, and make a diagnosis. Together you can come up with the best plan for your child.

You should always call your doctor, or go to an emergency room, if your child has a severe headache, a stiff neck, trouble with coordination or movement, is abnormally sleepy, or isn’t talking or behaving normally.

The American Academy of Pediatrics has additional useful information about migraines, and how to treat and prevent them, on their website.

Once influenza season is underway, it’s natural that if you hear your child start coughing, you wonder: could this be the flu or another virus? And if you think it is the flu, what should you do?

Is it the flu, RSV, COVID –– or just a cold?

It’s not always easy to tell these illnesses apart, especially at the beginning.

• Flu: The flu usually comes on suddenly, and its symptoms can include fever, runny nose, cough, sore throat, headache, muscle aches, feeling tired, and generally just feeling rotten. Some people have vomiting and/or diarrhea, too. Not everyone has all these symptoms, and the illness can range from mild to severe.
• RSV: Along with fever and sore throat (and feeling tired and rotten), RSV often causes a lot of nasal congestion and a mucusy cough. In some babies, it causes wheezing.
• COVID causes similar symptoms to flu and RSV, but the cough generally isn’t as mucusy, the fatigue can be worse, and some people will lose their sense of taste and/or smell.
• The common cold generally causes similar symptoms to flu, RSV, and COVID, but milder and often without a fever. However, some people have bad colds — and some people have mild cases of the flu, RSV, or COVID.

Call your doctor for advice

Because these illnesses are so similar, it’s a good idea to call your doctor’s office if your child has cold symptoms. You don’t necessarily need an appointment, but you should call for advice. Describe your child’s symptoms. Based on the symptoms, and your child’s particular situation (such as any medical problems they might have, or vulnerable people like infants or elderly living with you), your doctor

• may suggest testing for COVID, flu, or RSV
• may want you to bring your child in
• may want to prescribe antiviral medication.

Because every child and every situation is different, you should call and get advice that is tailored to your child and family.

What helps when your child has the flu?

Once you’ve called your doctor for advice or have a diagnosis of flu, the steps below will help your child feel more comfortable and speed recovery.

Stock up on supplies

There are a few things that make getting through the flu easier, including:

• acetaminophen and ibuprofen for fever and aches
• a reliable thermometer, if you don’t have one
• hand sanitizer (buy a few to keep all over the house)
• tissues
• fluids to keep your child hydrated, such as clear juices, broth, oral rehydration solution (for infants), and popsicles (which are great for sore throats, and eating them is the same as drinking). If you don’t have a refillable water bottle (one with a straw is great if kids are lying down), get one of those too.
• honey (if your child is older than a year) and cough drops (if your child is at least preschool age)
• saline nose drops
• a humidifier, if you don’t have one
• simple foods like noodle soups, rice, crackers, bread for toast.

Make sure your child rests

Turn off or at least limit the screens, as they can keep children awake when their body needs them to sleep. Keep rooms darkened, and limit activity. If they aren’t sleeping, quiet things like reading (or reading to them), drawing, card games, etc. are best.

Push fluids, don’t worry about food

When children are fighting the flu, the most important thing is that they stay hydrated. They need a bit of sugar and salt too, which is why juices and broths are good choices. If they only want water, give them some crackers to get the sugar and salt — but don’t worry too much if they don’t want to eat more than that. They will eat more when they feel better.

Watch for warning signs

Most children weather the flu fine, but some children get very sick, and there can be complications. Call your doctor or go to an emergency room if your child has

• a high fever (102° F or higher) that won’t come down with acetaminophen or ibuprofen, or a new fever after your child seemed to be getting better
• any trouble breathing
• severe pain of any kind
• severe sleepiness, so that it’s hard to wake them or keep them awake
• trouble drinking or keeping fluids down
• anything that seems strange or worries you (I always respect a parent’s “Spidey sense”).

Keep your child home until they are well

That doesn’t necessarily mean they can’t go to school or daycare until they are cough- or runny nose-free, but it does mean that they have to be fever-free for at least 24 hours, not coughing constantly, able to eat and drink, and have enough energy to do whatever school or daycare entails. Not only is this important for your child’s recovery, but it’s important for preventing the spread of influenza. Which leads me to the last point…

Do your best to keep others from getting sick

Besides keeping your child home (and staying home yourself if you catch it), there are other things you can do, such as:

• Make sure everyone in the house washes their hands frequently (that’s where the hand sanitizer all over the house comes in handy).
• Teach everyone to cover coughs and sneezes (they should do it into their elbow, not their hands).
• Don’t share cups, utensils, towels, or throw blankets.
• Wipe down surfaces and toys regularly.
• Discourage visitors (use technology for virtual visits instead).
• Be thoughtful about physical contact. Some degree of contact and snuggling is part of parenthood, but siblings may want to keep a bit of distance, and you can always blow kisses and do pretend hugs instead of the real thing.

Remember, too, that it’s never too late to get a flu shot if you haven’t already.

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

It’s a simple but unfortunate fact: driving skills can wane over time.

Eventually, driving can become unsafe for an older driver, their passengers, and others on the road. If you notice a decline in driving abilities in a loved one, or in yourself, what’s the best way to handle this?

If you’re an older driver: Create an action plan

If you’re an older driver, don’t wait for a near-miss or an accident to think about the next steps. Planning ahead can help you tackle fixable issues, make necessary transitions easier, and avoid harming yourself or someone else.

Here are six measures you can take right now:

Have a frank conversation with a trusted friend or family member. After driving with them as a passenger, ask whether they are worried about your driving. Don’t disregard their comments, even if they share things you don’t want to hear.

See your doctor and talk about your driving. Is it harder to see at night? Are you finding you’re slower to react? Ask your doctor about medical care that can help, such as cataract surgery, treatment for sleep apnea, or adjustments to medications that might affect driving.

Take a self-evaluation test or an on-road test.AAA has tools to help with this, or you can check with your local department of motor vehicles for options. Even if you feel it’s unnecessary, a driving test can be reassuring to your loved ones that you’re still safe behind the wheel.

Take driving classes. In many places, there are general refresher courses, courses for defensive driving, and even simulators that don’t require actual road tests. AAA and AARP offer online courses that can help you improve your driving. (And by the way, these courses may also reduce the cost of your auto insurance!)

Consider alternatives to how you drive. Stick to roads that are close to home or to routes that have traffic lights (rather than having to decide when traffic is clear enough to turn). Consider giving up night driving if that is particularly difficult.

Make adjustments to your car that can help. Examples include using a steering wheel cover to improve your grip or changing the position of your seat to improve your view of the road. Check out the CarFit program that aims to optimize the “fit” of a driver in their car.

In addition, explore options that don’t require you to drive as often or at all:

• grocery delivery
• public or senior transportation (if offered or available where you live)
• carpooling with friends or family
• ride-hailing services or taxis
• hiring a driver.

Cost and availability may be barriers, but it’s worth looking into these options.

If you’re a concerned family member or friend: Start a conversation

With so much at stake, the language you use matters. So, it’s a good idea to think ahead about how to talk about these challenges.

Put safety and solutions first. It’s best not to lead by criticizing driving skills. Instead, talk about driving with safety and solutions in mind, such as the options described above.

Choose your words carefully. It helps to avoid threats or confrontational language: rather than saying “Your driving is terrible so I’ve taken away your keys,” focus on safety and support:

•  
• Let’s talk about how I can help so you don’t have to drive. I can drive you to get your groceries on Sundays and we can make a day of it!
• How do you think those dents got on your car? Are you having trouble with your vision?
• We’d all feel terrible if you had an accident and got hurt or hurt someone else.

Offer to go for a ride together and then to talk about specific concerns, such as staying in the proper lane, changing lanes, making left-hand turns, speed, or sudden braking. Encourage consideration of a self-evaluation or on-road test, and driving classes to help polish skills.

Use examples from familiar experiences. It can be helpful to remind your loved one how his or her parents or grandparents had to cut back on their driving, or how an older neighbor was an unsafe driver.

Focus on the risks posed by other drivers. Aggressive or unpredictable drivers can pose more danger to older drivers with slower reaction times.

How else can families or friends of older drivers be helpful?

• Consider whether to contact their doctor. Ask their doctor if it’s possible to talk with your loved one or friend about their driving. State regulations vary on mandatory reporting of conditions that affect a patient’s ability to drive. Be aware that some doctors may be reluctant to report their patients to their registry of motor vehicles, due to concerns about patient privacy or jeopardizing the patient-doctor relationship.
• Look into rules and regulations around older drivers where your loved one lives. Illinois is currently the only state that requires a road test for older drivers. But many states require vision tests and in-person renewal with increasing frequency for older drivers.
• Consider reporting an unsafe driver to traffic safety authorities. This may feel like a betrayal, but if other efforts have failed this option might be better than waiting until there’s a serious accident.

The bottom line

In the future, safe, driverless cars may be a solution to the challenge of waning driving skills among older drivers. But we’re not there yet.

Right now, we should all acknowledge that it’s not easy to address concerns about impaired older drivers. My best advice is that older drivers and their loved ones try to talk about ways to remain a safe driver and put a plan in place. Ideally, we all would start the conversation well before any driving problems are evident.

And it may take more than one conversation. Many more. But let’s face it: sooner or later, most drivers will have to stop driving. For some older drivers, that time may be now. For the rest of us, recognizing this eventuality could help when our time comes.

The news these days is overwhelming in its awfulness. Acts of terrorism, wars, and heated conflicts constantly erupt throughout the world. Climate change looms, contributing to wildfires and flooding. Incomprehensible shootings occur with numbing regularity. The pandemic seems to be shifting from an immediate threat to health to an endemic illness — yet it’s still affecting us. The news has been so horrible, and so unrelenting, that it is hard to even process it.

Imagine processing it as a child?

Our first instinct is usually to shelter our children from the news and not say anything about it to them at all. That’s completely understandable, and if your child is very young or you are certain for some other reason that they aren’t going to hear about it, then not saying anything is a viable option.

But if they aren’t very young, or if you ever have the news on where they can see, or if they are ever in settings where people might have the news on or talk about it, it might not be so viable. If children are going to hear about something, they really should hear about it from you.

Also, as parents it’s important that we give our children the perspective and skills they need to navigate this scary world where, let’s be honest, bad things happen. The way you talk to children about tragedies in the news can help them cope not just now, but in the future.

The American Academy of Pediatrics has all sorts of resources to help parents talk with children about tragedies. Here are four simple things all parents can and should do:

1. Tell them what happened, in simple terms. Be honest, but skip the gory details. Answer their questions just as simply and honestly. If you think — or know — that your child has already heard something, ask them what they’ve heard. That way you can correct any misinformation, and know not only what you need to explain but also what you may need to reassure them about.

2. Be mindful of the media that your child sees. The news can be very graphic, and because the media are as much in the business of gaining viewers as of delivering news, they tend to make things as dramatic as possible and play footage over and over again. When the planes flew into the Twin Towers on 9/11, my husband and I were glued to the television, not realizing that one of our daughters, who was 3 years old at the time, thought that planes were literally flying into buildings again and again. It wasn’t until she said, “Are those planes going to come here too?” that we shut off the TV and didn’t turn it back on again until all the children were in bed.

3. Make sure your child knows that you and others are always doing everything you can to keep them safe. Talk about some of the ways you keep them safe, ways that are relevant to the tragedy you are talking about. Make a safety plan as a family for things like extreme weather or getting separated. Help them think about what they might do if they are ever in a scary situation, and who they could turn to for help. Which leads me to the most important thing to do…

4. Look for the helpers. The wonderful Fred Rogers often talked about how when he saw scary things on the news, his mother would tell him to look for the helpers, because there are always people who are helping. That may be the best thing we can do as parents: help our children look for the helpers. In all of the recent tragedies, as in all tragedies, there were so many helpers and heroes. When we concentrate on those people, not only do we give our children hope, but we may empower them to one day be helpers too.

The world can be a scary place, yet there is much we can do — from a very young age — to help children build strengths and nurture resilience, even in the face of tragedy.

Childbirth — painful, messy, unpredictable — has been part of humankind for time immemorial. And in the US, which has surprisingly high rates of avoidable complications and maternal deaths, more people seem to be seeking out doulas for additional care during pregnancy and birth, says Natalia Richey, interim chief midwife in the Department of Obstetrics and Gynecology at Massachusetts General Hospital.

Some research suggests that doula care may benefit both mother and baby. But what does a birth doula do? While neither a midwife nor a doctor, a professional doula can provide emotional and physical support to women during pregnancy and throughout the birthing process.

Here’s what to know if you’re considering doula care.

What’s the difference between doulas and midwives?

Midwives and doulas tend to have a few overlapping duties. But there’s a key difference: midwives provide medical care and doulas don’t.

• Midwives: Their primary responsibility is to maintain the physical health of a woman and her baby throughout childbirth. Certified nurse-midwives like Richey are also trained nurses, but most midwives have undergone some type of medical training. This may vary depending on state laws.
• Doulas: Unlike midwives, doulas don’t perform any medical tasks. Their main role is to help laboring women remain comfortable and calm using various methods, including suggesting comfort measures and optimal positions for labor and pushing.

“Many women hire doulas if they’re trying to have an unmedicated birth,” Richey says. “Doulas are really good at knowing what techniques — such as walking, showering, massage, or aromatherapy — can help a woman through the pain. It’s like having a coach.”

Are doulas trained or licensed?

Be aware that doula training varies widely. There are no formal rules requiring licensing or certification. Many doulas, however, seek certification from the more than 100 independent organizations that offer some type of doula training and credentials, according to the National Health Law Program.

Is doula care covered by insurance?

Private insurers often do not cover doula care, which can cost several thousand dollars when arranged for privately.

However, some employers — including Walmart — will help pay for doula care. And some hospital systems, particularly in low-income or medically underserved areas, have doula programs aimed at improving maternal care during and after pregnancy. Others may arrange doula support for people with limited resources who might otherwise be alone during the later stages of pregnancy and birth.

As of February 2023, 10 states and the District of Columbia provided Medicaid coverage for doula services. Other states are in the midst of implementing coverage. Most of the states that provide Medicaid coverage for doula care require doulas to be trained or certified by an approved organization.

Can working with a doula improve birth outcomes?

A 2023 analysis in the journal Cureus reviewed 16 individual studies done over 22 years. It found doula support was linked with better birth outcomes, such as fewer C-sections and premature deliveries, and shorter length of labor.

Additionally, the emotional support provided by doulas was associated with less anxiety and stress in birthing mothers. Among low-income women, doula support was shown to improve breastfeeding success.

“It’s impressive,” Richey says. “I think those improved outcomes are due to having an expert in the labor process who isn’t a medical person but is just there for you from moment to moment.”

How do people collaborate with doulas?

Agreements about care vary. Typically, doulas meet with women every few months through their pregnancy to discuss their goals for birth (such as skipping pain medication, for example), and to build rapport with both the expectant person and their spouse or partner.

Like obstetricians, doulas are on call 24/7 to support clients who have gone into labor or who have their labor induced. Doulas stay throughout the birth process.

“Having someone there who’s seen quite a few births, who can support and advocate for them, can be a huge comfort,” says Richey.

This may be especially important to women with limited resources, particularly those who might otherwise be alone during the later stages of pregnancy and birth. “Doulas remind women that they’re okay and can get through this process — all the things many of us take for granted,” Richey says.

How might a doula work with the OB/GYN team?

Usually, this is a seamless process, Richey says. If a hospital arranges for a woman’s doula, OB/GYN team members may meet the doula a couple of times before childbirth. Meanwhile, a doula who’s been hired privately will usually only meet the larger OB/GYN team when the woman arrives at the hospital to give birth.

When everyone sticks to their assigned roles, all goes smoothly. For a doula, that may mean suggesting nonpharmacological ways to ease pain and help labor progress. Boundaries are important, though, when medical intervention is needed.

“If the baby’s heart rate is down, for instance, the expertise needs to be left to the midwife or doctor,” Richey explains.

What questions should you ask if you’re interested in working with a doula?

Richey suggests starting by asking yourself:

• What are my hopes and goals for the childbirth process? Might a doula enhance my ability to achieve them?
• How do I envision my support team during delivery? Do I have a partner, a mom, or a friend I want there? Would a doula add to any support I already have?
• Do I have friends or family members who have used doulas in the past? What were their impressions of the experience? Can they recommend a doula?

If you contact a doula to explore your options, ask about:

• their training and certification
• how many births they’ve attended
• how they believe they can help you during your pregnancy and during labor
• how they will collaborate with your partner or spouse and the medical team
• whether they provide support after a birth — if so, what type of support and for how long?

“Take the time to meet with any doula you’re considering and make sure they’re a good fit,” Richey advises, “because this is someone who will be there during one of the most vulnerable times of your life. Having someone there who doesn’t make you feel safe and comfortable can affect birth in a major way.”

It’s no secret that the typical American diet isn’t very healthy. Only about one in 10 American adults eats the recommended daily amount of fruit (1-1/2 to 2 cups) or vegetables (2 to 3 cups). These dietary shortfalls are even more pronounced among people in lower income groups. And the health impacts are substantial: In the United States, poor diets have been linked with more than 300,000 annual deaths from heart disease and diabetes.

Produce prescriptions enable health care workers to give vouchers for free or discounted produce at grocery stores or farmers’ markets to people living in low-income neighborhoods. A recent study asks whether these programs might help people at risk for heart disease eat more fruits and vegetables, and possibly improve health issues like high blood pressure. While Dr. Anne Thorndike, an associate professor of medicine at Harvard Medical School who studies cardiometabolic disease prevention and nutrition security, questions some findings in the study, she notes that there are lessons to be learned here.

How was the study done?

The study pooled data on nine different produce prescription programs given out in 22 locations spread over a dozen states across the country. A total of about 2,000 adults and 1,800 children from low-income neighborhoods were enrolled. Participants received vouchers or cards to buy produce worth $15 to $300 per month (depending on family size). They also attended nutrition classes.

The programs lasted between four and 10 months. At the start and end of each program, participants filled out questionnaires about their fruit and vegetable consumption and health status. The questionnaires also asked about food insecurity, which is not having access to adequate food to meet one’s basic needs. Blood pressure, blood sugar, height, and weight were recorded for some program participants.

What were the findings?

During the produce prescription program, adults ate nearly one additional cup of fruits and vegetables per day; children ate an extra quarter-cup daily. In adults, these changes were associated with lower blood pressure in people who had high blood pressure and lower blood sugar in people who had diabetes. The researchers also documented drops in body mass index (BMI) among adults with obesity.

All glowing results, right? Well, maybe not.

“Because of the study’s limitations, including a lack of a comparison group — which is standard practice in diet studies — those potential health benefits are hard to prove,” says Dr. Thorndike. In addition, the investigators relied on statistical techniques to account for high rates of missing data from some programs, which could also skew results.

It’s hard to imagine how eating an extra serving of produce daily could lower BMI values within six months, says Dr. Thorndike. “However, there’s so much strong data that associates eating a healthy diet, particularly one that includes plenty of fruits and vegetables, with a lower rate of almost every chronic disease, including heart disease, cancer, and dementia,” she adds.

The bottom line

While flawed, this research is interesting, and highlights the need to improve diet quality for all Americans, especially those who face added barriers due to their financial circumstances.

“I’m a huge believer in produce prescriptions,” says Dr. Thorndike, “and part of my research mission is to determine the best way to design and deliver them so people get the greatest possible health benefit.”

The study also helps raise awareness about food insecurity, which affects about one in 10 American households. At the start of the study, more than half of the households participating reported food insecurity. Among all the participants, reported rates of food insecurity dropped by one-third by the end of the program compared to the start.

“We all need to acknowledge that many people are less healthy because they can’t get access to or afford the foods they need to prevent or treat disease,” Dr. Thorndike says. Broadening the focus beyond produce to “prescribe” other types of healthy foods, such as whole grains and lean proteins, may be another helpful solution, she adds.

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.

If you’ve ever dealt with diarrhea, you know how quickly it leaves you feeling depleted. Now imagine a case that rages on and on — or comes back again and again.

This is the reality for nearly 500,000 Americans each year who have the bacterial infection known as Clostridioides difficile, or C. diff. Virulent diarrhea and inflammation of the colon can even turn life-threatening.

This primer will help you understand how C. diff spreads and releases toxins, what the common symptoms are, and who is most vulnerable. Dr. Jessica Allegretti, director of the fecal microbiota program at Harvard-affiliated Brigham and Women’s Hospital, also touches on promising preventive strategies and treatments.

How does C. diff spread?

Like many bacteria, C. diff is present in our stool. It’s carried by virtually everyone — on our skin and even on the soles of our shoes. When C. diff bacteria are outside the body, they are inactive spores. They only have a chance to become active when they’re swallowed and reach the intestines.

Even then, many people who swallow C. diff spores never become ill. The spores only sicken people whose gut microbiome — the trillions of organisms living in their intestines — becomes imbalanced for one of the various reasons described below. When an imbalance occurs, the spores start to multiply and create toxins that lead to a C. diff infection.

“Many of us are colonized with C. diff bacteria without any consequences,” says Dr. Allegretti. “We’re swallowing C. diff spores all the time. Only under the right circumstances will the spores germinate and release a toxin. It’s the toxin that makes you sick.”

What are the symptoms of a C. diff infection?

The symptoms mimic those of many other types of gastrointestinal ailments. Initially, this may make it difficult to tell the infection apart from milder illnesses.

Symptoms to watch for include

• persistent diarrhea lasting three or more days
• nausea
• fever
• stomach pain or tenderness
• appetite loss.

“C. diff isn’t something that people in the general population should be walking around scared of,” Dr. Allegretti says. “But if you need to take an antibiotic, be on the lookout for diarrheal symptoms after finishing the course of antibiotics. Diarrhea that’s associated with antibiotics alone should resolve once you finish taking the medication.”

Who is most vulnerable?

A few sobering facts from the Centers for Disease Control (CDC):

• C. diff is the top cause of health care-associated infections in the US.
• It disproportionately strikes people in hospitals and nursing homes.
• Among people over 65, one in 11 of those diagnosed with a health care-associated case of C. diff dies within a month.

However, other groups are also susceptible to the infection. Health care-associated C. diff infections are plateauing, Dr. Allegretti notes, while so-called community-based infections that occur among the general population are increasing.

People most likely to experience such infections:

• Are taking antibiotics or have just finished a course of antibiotic therapy. People are up to 10 times more likely to get C. diff while on antibiotics or during the month afterward, according to the CDC. “Not everyone who takes an antibiotic gets C. diff, and not everyone who gets C. diff gets recurrent C. diff,” says Dr. Allegretti. “It has a lot to do with your host response, your gut microbiome, and your individual risk factors, such as immunosuppression or inflammatory bowel disease.”
• Have a weakened immune system due to cancer, organ transplant, or treatment with immunosuppressive drugs (such as people with inflammatory bowel disease or autoimmune conditions).
• Have close contact with someone who has been diagnosed with C. diff.

What prevention strategies help block the spread of C. diff?

Hospitals try to prevent C diff. among patients in several ways. They impose scrupulous hand-washing requirements among staff members. Patients who develop new diarrhea are tested for C. diff infection. Those who have it are isolated in their own rooms to help prevent further spread.

Outside of a hospital, you can help prevent this gut infection through a few commonsense measures.

• Wash your hands thoroughly with soap and water every time you use the bathroom and always before eating. Clean hands are especially important if you’ve had C. diff or know you’ve been exposed to someone with it. By the way, alcohol-based hand sanitizer isn’t effective against C. diff because its organisms can form resistant spores.
• Take antibiotics only when strictly necessary and for the shortest period possible. “The biggest thing we can do is advocate for ourselves,” Dr. Allegretti says. “During cold and flu season, we know a lot of unnecessary antibiotic prescriptions are written for infections that are most likely viral, not bacterial. Antibiotics do not kill viruses — and unnecessary antibiotics may upset the bacterial balance in your gut. Ask your doctor: Do I need this prescription? Is there an alternative?”
• When you do need antibiotics, ask if a narrow-spectrum antibiotic would be effective for your type of infection. Why? Broad-spectrum antibiotics kill a wider array of bacteria. This may be overkill, depleting your gut microbiome unnecessarily and enabling C. diff bacteria to germinate. “The caveat is, we don’t want patients to not take antibiotics they need for an actual infection,” she says. “But have a conversation with your health care team.”

The type of antibiotic prescribed also matters, according to a 2023 study in the journal Open Forum Infectious Diseases. Researchers compared more than 159,000 people who had C. diff infection with 797,000 healthy controls. Study findings suggest that using clindamycin and later-generation cephalosporin antibiotics pose the greatest risk for C. diff infection. Meanwhile, the antibiotics minocycline and doxycycline were associated with the lowest risk.

“But there are very few safe antibiotics with regard to C. diff risk,” Dr. Allegretti says.

Can probiotics help prevent or treat C. diff infection?

Probiotics are live microorganisms that can help keep the gut healthy and are found in supplements, yogurt, and other fermented foods. Two familiar examples are various strains of Lactobacillus and Bifidobacterium.

However, probiotics haven’t been found to prevent C. diff or its recurrence. Research performed in mice and humans suggests that giving probiotics after a course of antibiotics may slow the pace of microbiome recovery. “You’re potentially delaying the recovery of your microbiome with probiotics,” she says.

How is C. diff infection treated?

Ironically, C. diff therapy typically starts with antibiotics, despite the infection’s proliferation due to antibiotic use. The antibiotics of choice include fidaxomicin or oral vancomycin.

However, about one in five people will suffer one or more recurrences –– and with each one, yet another recurrence becomes far likelier, Dr. Allegretti says. A repeat episode may happen because people haven’t disinfected their homes effectively. That leaves them open to reinfection with the same strain of C. diff while still vulnerable.

When C. diff recurs, fecal microbial transplants (FMT) are considered the gold standard treatment. FMT transplants fecal matter from a healthy donor into a patient’s gut, placing it there using an endoscope, enema, or within an oral capsule. This year, the FDA approved two live fecal microbiota products aimed at preventing recurrent C. diff infections.

“We haven’t gotten away from antibiotics yet to treat this disease,” says Dr. Allegretti. “But we have a lot of preventative strategies now. It’s certainly very exciting for people struggling with C. diff infections.”
