A 2026 study suggested that feeling lonely was consistently linked to worsening cognitive health and a shorter life among older adults, even after accounting for social isolation.

Longevity (or healthspan) specialists focus on preventing age-related disease and extending people’s healthy years, rather than waiting to treat illness once it appears. Ideally, a longevity specialist focuses on proven health fundamentals before supplements and experimental therapies.

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?

A small, short-term 2026 study suggests that people who schedule their exercise to align with their chronotype—the body’s natural sleep and wake cycle—may lower their heart risk factors more than those who exercise at times that don’t align with their chronotype.

Sleep comes in two different forms: REM (dreaming) and non‑REM (quiet) sleep. In quiet sleep, your brain shifts from chaotic awake activity into calm, rhythmic waves as if a switch has been flipped. In a healthy night, you glide through three deepening stages of non‑REM (N1, N2, N3 slow‑wave sleep) before diving into vivid REM dreams.

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.

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.

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).

Insomnia is linked to an increased risk of atrial fibrillation (afib), a heart rhythm disorder, according to a 2026 study. Insufficient sleep may trigger physiological and hormonal changes that may leave people more susceptible to afib.

Do you wake up tired, struggle to fall asleep, or rely on caffeine to get through the day? Your daily habits may be playing a bigger role in your sleep quality than you realize. This quick quiz will help you evaluate your sleep hygiene from your bedtime routine and screen use to exercise, stress, and sleep environment.
