Sitting too much is bad for health. But there are ways to make time spent seated a little healthier. For example, people can keep their brains active by reading, writing, doing a hobby (such as knitting), or playing an instrument. And people can exercise while in a seated position. It's possible to do an aerobic workout that gets the heart and lungs pumping, such as a seated dance routine or calisthenics, as well as muscle-strengthening activities or stretching exercises.

By age 40, one in five women has dealt with an eating disorder, twice the proportion of women known to be affected by age 21. Risks for anorexia, bulimia, and binge eating can rise at midlife due to job stressors, an empty nest, and dating again after divorce or widowhood. Health effects can include bone loss, heart problems, lung conditions, gastrointestinal issues, diabetes, and skin breakdown. Signs of an eating disorder include dramatic weight fluctuations, excessive exercising, and preoccupation with weight, calories, and body size and shape.

Many people say they feel joint pain that arrives with cold or damp weather. While research hasn't confirmed why, changes in barometric pressure can place pressure on joints that may lead to aches.

People may relieve anxiety by cracking knuckles or other joints. Usually it's a harmless habit, but people with joint problems like arthritis should refrain, since doing so might worsen symptoms.

Body-weight exercises are ideal substitutes for regular workouts when people are short on time or looking to shake up their usual routine. These types of exercises are not only versatile—as they can be done anytime, anywhere, without any equipment— but they also help improve everyday movements by activating the smaller stabilizing muscles that sometimes get missed when a person uses gym machines or dumbbells.

Stretching the muscles that support the spine can help alleviate persistent or recurring low back pain. The muscles to stretch include the erector spinae muscles along the spine, the iliopsoas muscles connecting the spine to the lower limbs, and the abdominal muscles in the front of the body that help prop up the torso. Other muscles that support the back include those in the front of the hips, back of the thighs, and buttocks. An example of a back stretch is lying on a bed and pulling the legs close to the chest for half a minute.

Around menopause, a decline in estrogen can trigger low-grade inflammation that leads to unexpected symptoms from head to toe. Symptoms can affect the digestive tract, skin, joints, eyes, ears, and heart, among other areas. A 2022 study found that estrogen loss can even fuel the jaw pain known as temporomandibular disorder. A year or longer can pass before many women connect symptoms with menopause. Women can take lifestyle measures to lower inflammation, such as eating more fruits and vegetables, avoiding processed foods, and exercising.

Non-contact boxing has been shown to help many people with Parkinson's disease improve their balance, hand-eye coordination, mental focus, muscle strength, and body rhythm. Older adults also can benefit from this type of exercise, as they face many of the same physical and mental challenges as they age. Most boxing fitness workouts are done using punching bags and hitting oversized boxing mitts worn by coaches. The moves involve punches and sequences based on crosses, hooks, uppercuts, and jabs.

A large study published online June 23, 2022, by JAMA Network Open found that poor handgrip strength in midlife was associated with cognitive decline a decade later.

It's safe to work the core every day for about 10 to 30 minutes, as long as a person doesn't develop intense muscle fatigue. There are so many kinds of core-strengthening activities that it's possible to do a different one each day of the week. Ideas include marching, practicing yoga, doing body-weight workouts, exercising in a pool, and doing housework. Before a core workout, a person should do a warm-up, such as walking, to get blood flowing to the core muscles. After exercising, it's important to stretch the core muscles to help lengthen them and keep them flexible.
