Physical activity and exercise Archive

There are things our bodies do so often and so automatically that we barely notice them. Yawning, growling stomachs, and runny noses are good examples. Each is a universal part of our daily human experience — but did you ever wonder why?

Beyond familiar kettlebell exercises such as kettlebell swings, many lesser-known kettlebell moves can create a full-body workout. Examples include around-the-world passes, bottoms-up kettlebell carries, and kettlebell deadlifts.

People’s energy levels typically decrease later in life as a result of aging, illness, or other factors. Fortunately, a healthier lifestyle can boost energy. That involves eating a diet low in added sugars and processed foods, getting seven to nine hours of sleep each night, managing stress, getting lots of aerobic exercise, and strengthening the muscles. Using physical energy frugally is another useful strategy. For example, it helps to perform activities at a slow, steady pace instead of a fast pace; to break activities into small tasks instead of one large job; and to rest between tasks.

Falls among older adults are on the rise, but most are preventable. To do this, interventions must target the multiple factors that contribute to falls, taking steps to minimize them or prevent them entirely.

Many strategies can help people avoid falls in public places. For example, people can wear shoes with nonslip treads in stores and office buildings, use a rollator for stability in crowded areas such as airports or shopping malls, hold handrails on public staircases (or avoid them), avoid parking too close to vehicles in parking lots, or use the handicap stall in public bathrooms. Another important strategy is regularly strengthening leg and core muscles and practicing balance exercises (such as standing on one leg).

What could you do today to feel happier? Three strategies drawn from positive psychology, a field that aims to improve moods and lives, may help.

A variety of disparate factors can speed up people’s biological aging, which describes how well their body functions (in comparison to chronological aging). Drivers of aging include ultraviolet light, stress, smoking, obesity, radiation, and loneliness and social isolation.

Older adults need a strong core to stay active and healthy. While the core comprises many muscles, the four main ones lie within the abdomen: the rectus abdominis in the front; the external and internal obliques on the sides; and the deep, flat transversus abdominis wrapping your midsection. Several core exercises work many of these muscles, but the dead bug exercise can engage all of them and is safe for older adults, as it can be modified for any age or limitations. The dead bug is done by lying on the back and moving the limbs up and down to imitate a dying insect.

A 2026 study suggested that women who consistently stay active throughout middle age have a significantly lower risk of dying early than peers who are inactive.
