Unlocking the secrets of super-agers

Super-agers are people who reach their 80s, 90s, or beyond with the memory capacity of someone at least three decades younger. As people get older, certain brain regions shrink, slowing brain functions. But super-agers retain more brain volume in areas linked to memory and movement, and their brains shrink more slowly over time. Women are more likely to be super-agers because they live, on average, longer than men. Genetics also appear to play a significant role in achieving super-ager status.

A popular alternative to a traditional sleeping pill

In the last few years, the prescribing rate for zolpidem, a popular sleeping pill, has been declining in favor of the "off-label" use of an antidepressant called trazodone, which is known for its ability to make people drowsy. But doctors are concerned that trazodone hasn't been well studied for insomnia, it is not FDA-approved to treat the condition, and there are sparse data showing that it is safe or that it works for patients with insomnia. Experts advise choosing medications based on a patient's specific needs, not a trend.

Substituting plant oils for butter can lead to better health

People who consume plant-based oil instead of butter may have a lower risk of death from cancer and cardiovascular disease, according to a 2025 study. These oils have more heart-healthy unsaturated fats, which help lower cholesterol levels and chronic inflammation.

Wake-up to managing poor sleep

Guidelines recommend at least seven hours of sleep nightly for most healthy adults. But instead of fixating on a specific number of hours, experts suggest people focus on how well they sleep, also known as sleep quality. Improving sleep quality starts with recognizing the factors contributing to poor sleep. One way is for people to keep a sleep diary for one to two weeks to record details of their sleep experience. Afterward, they can review the information to identify any patterns that may be affecting their sleep and make adjustments.

Prepare now for your health needs in the future

If possible, everyone should prepare for the possibility of needing support services or long-term care in older age, even if it’s not yet needed. Ways to prepare include designating a health care proxy and power of attorney; writing advance directives for health care preferences; investigating potential housing options (such as assisted living facilities) and support services (such as a health aide) well in advance; downsizing belongings, including one’s home; and meeting with a financial planner to figure out how to tackle caregiving expenses.

High temperatures may make natural mosquito repellents less effective

Mosquito repellents that rely on certain natural substances may not be as effective when temperatures reach 90° or higher. For very hot weather, people may get better protection by using the synthetic repellent DEET.

Do collagen supplements fulfill their promises?

The protein collagen supports skin, hair, nail, bone, joint, and muscle health. As people age, natural collagen production drops. Some early research suggests collagen supplements offer benefits, but people should ask their doctor about the pros and cons.

Heat wave hazards

Certain medications can leave people more vulnerable to heat-related effects or the sun's rays. The medications can raise the risk of dehydration, make people sweat too much or too little, impair the body's ability to regulate temperature, or raise the risk of getting a bad sunburn. In addition, higher temperatures may damage some medicines, including diuretics, blood pressure drugs, some antidepressants, thyroid replacement hormones, and some over-the-counter antihistamines.

Water aerobics tied to weight loss and a smaller waist

A 2025 review of 10 randomized controlled trials (involving about 300 people) found that those who took part in two or three one-hour water aerobics classes weekly for at least 10 weeks lost up to 6 pounds and trimmed their waists by about an inch.

Twist, turn, tone

Dancing is a popular leisure activity. Evidence suggests dance boasts all the same benefits as other forms of consistent aerobic exercise: lowering blood pressure, building muscle and bone, increasing aerobic capacity, reducing anxiety, and improving depression symptoms. Dance can also counter loneliness and isolation and be easier to stick with than exercise that’s more repetitive. People who want to try dance can frame it as a hobby instead of exercise, take a group class, and modify dance movements to accommodate pain or limited mobility.
