The combination of drinking alcohol and sleeping while on a plane puts a big strain on the body, especially the cardiovascular system. This is because blood oxygen normally drops slightly when flying high above sea level, sleeping, or consuming alcohol. The more contributors to low blood oxygen there are, the harder the body has to work to compensate by breathing faster and increasing heart rate. There's even more strain if someone has heart or lung disease, which places the person at a higher risk for a heart attack or stroke.

A 2024 study suggests that having one or more tattoos may raise a person's risk of developing lymphoma, a type of blood cancer.

Online hearing tests help detect if someone has hearing loss. The tests involve answering questions or listening to a series of tones or spoken words. The tests are not as comprehensive as tests conducted by an audiologist, but they are convenient and might help identify mild, moderate, or severe hearing loss; problems hearing particular pitch ranges; or differences in hearing ability in one ear compared to the other (asymmetry). A test might need to be followed up with a visit to an audiologist.

A 2024 study found that women who closely followed a Mediterranean diet were up to 23% less likely than women who didn't to die over a study period of 25 years.

Body roundness index, which is calculated based on a person's height, waist, and hip size, might be a more accurate measurement than body mass index for predicting weight-related health risks, according to a 2024 study.

People often aren't aware of the full range of conditions that physical therapy (PT) can effectively treat. PT can be used not only after surgery or injury, but also for stroke, brain injuries, balance problems, neuromuscular conditions, spinal cord injuries, and more. PT is also done to help people avoid falls, as well as for pelvic floor dysfunction and vertigo. People participating in PT work with physical therapists to determine goals and plan a course of treatment to meet those goals by improving mobility, strength, and flexibility.

Walking is one of the most accessible and versatile types of exercise. It can help people get the recommended 150 minutes of moderate-intensity exercise per week, and workouts can be adjusted to fit any fitness level. But sometimes walking becomes too routine. To make outings more exciting and challenging, people can do interval training, add hills or stairs, use walking poles, carry weights, incorporate body-weight exercises, or try to beat their best time on a route.

The 1,000 Hours Outside challenge can motivate people to spend more time outdoors by trying to accumulate 1,000 hours of outdoor time over a year.

Artificial intelligence (A.I.) has made an astonishing breakthrough in our understanding of certain biological processes. A.I. has now determined the structure of nearly all proteins in humans, plants, and animals and is exploring the way they interact with each other and with other molecules. This understanding is considered the key to biological medicine, a code that scientists have never been able to crack completely. These advances are expected to speed the development of many potent medicines, vaccines, and cures for some diseases.

A 2024 study of people ages 80 and older suggested that following healthy habits—like eating a diversified diet that includes high amounts of fruits, vegetables, fish, beans, and tea; regularly exercising; and not smoking—can help people live longer.
