A brief fitness test may predict how long you'll live

In a 2025 study, middle-aged and older people who could do the sit-to-rise test without support were less likely to die (especially of cardiovascular disease) within the following decade. The test is a good way to assess strength, flexibility, and balance-all of which are all vital for helping people to stay active and functioning well as they grow older.

Is it normal for my joints to click?

There are many normal reasons people's joints make clicking, popping, cracking, or other noises. Joints are also more likely to make noise when people stay still for long periods. Pain or swelling with joint noise should prompt people to see a doctor.

5 timeless habits for better health

Influencers, news headlines, and well-meaning friends and family offer conflicting advice on wellness. Quick fixes and fads may do little for our health, and some even prove harmful. Try to work these five simple habits that can boost health and wellness into your everyday life.

Fresh-faced through the years

With age, people develop brown spots, wrinkles, and sagging skin. Women are more likely than men to invest money and time to look younger. Sun protection and a variety of skin care products can help, including those containing alpha-hydroxy acids, retinols, vitamin C, and hyaluronic acid. Minimally invasive cosmetic procedures can also ease signs of aging. These include injections of botulinum toxin (Botox) or hyaluronic acid, laser treatments, and chemical peels. Skin care and treatments should be customized to each person.

Do I need to rebalance my pH?

The body's pH level supports a variety of crucial functions. Certain health conditions can create a pH disturbance. People can support a healthy pH by eating a balanced diet featuring fruits, vegetables, whole grains, lean meat, and fish.

Living in the Blue Zone

The Blue Zones are locations in the world where people are regarded as being among the healthiest and longest-lived. They include Okinawa, Japan; Ikaria, Greece; Sardinia, Italy; Nicoya, Costa Rica; and Loma Linda, California. According to some research, most residents of Blue Zones live seven to 10 years longer than the average American and have lower rates of cancer, cardiovascular disease, diabetes, and dementia. These individuals follow certain healthy behaviors related to diet, exercise, and emotional well-being that people can adopt.

Power play

Power is the ability to generate a large amount of force in a short amount of time. It can help people to properly and safely execute many everyday movements, such as climbing stairs, lifting and carrying heavy objects, twisting, pulling, and throwing. Power also improves movement efficiency and reaction time, helping to prevent injuries from falls. Increasing overall muscle mass with regular strength training and doing plyometric exercises and explosive moves using a medicine ball can help build power.

Will vitamin D supplements keep me younger?

In a 2025 randomized trial of about 1,000 people (ages 50 or older), followed for four years, those who took 2,000 international units of vitamin D3 per day showed cellular signs that suggested they were aging more slowly compared with people who did not take the supplement. It's unclear if this benefit would continue from taking daily pills longer than four years. Scientists do know that taking vitamin D3 supplements is important for people with osteoporosis or with vitamin D deficiency (as determined by a blood test).

Eating diverse flavonoid foods may provide extra health protection

Eating a variety of flavonoid-rich foods may offer greater protection against cardiovascular disease and cancer than eating only a few high-flavonoid foods, according to a 2025 study.

Is constant gum-chewing a bad idea?

Evidence suggests that chewing gum can help people feel more focused and less stressed. Chewing sugar-free versions can hinder cavities. But constant gum-chewing can tire jaw muscles, and xylitol-containing gum can trigger abdominal distress.
