Many professional athletes and celebrities swear by the therapeutic benefits of ice bathing, which involves briefly immersing one's body in cold water. The science around possible health benefits is thin. Still, fans say the practice makes them feel mentally and physically invigorated and reduces muscle soreness. People can try ice baths by filling their tub with cold water and immersing themselves as completely as possible for several seconds to a few minutes.

The original Presidential Physical Fitness Test consisted of five exercises: a one-mile run, pull-ups or push-ups, sit-ups, shuttle run, and sit-and-reach. The test gauged upper-body and core strength, endurance, flexibility, and agility for America's youth. Still, with some modifications, older adults can use the test to assess a baseline of their fitness and identify areas where they need to improve.

There are many varieties of low-carb diets. Each has its unique approach and some may help jump-start a weight-loss program, But long-term use of very low-carb diets can lack essential micronutrients and may raise the risk of health problems.

A professional head shave done by a barber is an easy, no-fuss way to maintain a shaved head. But do-it-yourselfers can get a clean shave by following these simple steps: cut the hair close to the scalp with an electric trimmer; rinse with warm water; cover the head with shaving oil, gel, or foam; then shave in the direction of hair growth with an electric shaver or a cartridge or safety razor, or both for a close shave.

Older adults might be able to lower their blood pressure by reducing their sitting time by as little as 30 minutes per day, according to a 2024 study.

People who have or are at risk for cardiovascular disease should be extra cautious when exercising outside when it's hot, humid, and hazy, as they are more vulnerable to the hazards of high temperature and air pollution. To exercise safely during a heat wave, people should avoid being outside during the middle of the day; wear light-colored, lightweight clothing; and be careful to stay hydrated.

While the best health outcomes are linked to taking about 10,000 steps per day, people who walk as little as 2,200 steps may lower the odds of developing heart disease or dying early compared to those who walk fewer steps.

A 2023 study suggests habitually adding salt to food may raise the odds of developing chronic kidney disease, which increases the risks of heart disease, stroke, and kidney failure.

Two-thirds of Americans with long COVID are women. Women approaching menopause who have long COVID seem to experience worsened symptoms of both conditions. Women's sex hormones appear to contribute to this phenomenon. Hormone therapy is becoming both a treatment and a diagnostic tool to determine driving factors behind affected women's symptoms. Because symptoms overlap, some women may have trouble being correctly diagnosed with perimenopause or long COVID.

Women and men require different nutritional approaches to promote muscle recovery after exercise. Optimally, women should refuel within 45 minutes, while men have up to three hours. Hormone differences drive women's faster post-workout muscle breakdown. During the luteal phase of the menstrual cycle, women may also crave more carbohydrates and want to eat more. Women should consume about 20 grams of protein within 45 minutes of working out. If fat loss is desired, women should cut calories at other times of the day, not after exercise.
