Periodontal disease, the leading cause of adult tooth loss, may increase the risk of diabetes, heart disease, and dementia.

Depression may be more common as people age, but new data suggest that the biggest threat to older adults’ mental health is their failure to recognize its symptoms and seriousness. Many chalk up depression as a normal part of aging, but addressing it as a real and treatable disease can help older adults seek the help they need and not needlessly suffer.

Good dental health protects against not only gum disease, gum inflammation, and tooth loss but also many other age-related diseases. Like other aspects of health care, prevention is the best medicine when it comes to your teeth and gums. People should see their dentist every six months for check-ups, x-rays as needed, and cleanings. In between, they should follow a daily dental hygiene routine of rinsing, brushing, and flossing to help reduce plaque buildup, gingivitis, and cavities.

But there is another element to healthy aging: keeping your mind engaged helps protect brain health, and one way to do that is by maintaining an active social life.

Epigenetics is the study of how behavior, the environment, and other factors can trigger chemical changes to DNA or nearby proteins that affect how genes work. Collectively, these changes (known as epigenetic marks) may provide clues about health and longevity.

Past smoking, heavy drinking, and drug use can raise lasting questions about aging. Find out which factors shape future health and longevity.

The term “longevity” encompasses both living longer and staying in good health. Research consistently indicates that five lifestyle pillars promote longevity: movement, nutrition, sleep, stress reduction, and socialization. But it’s impossible to gauge which pillar counts most toward longevity.

Gray divorce—which involves couples ages 50 and older ending their marriage—has become more common over the past 30 years. While divorce increases the odds of mental and physical health problems at any age, older adults face heightened health risks during a stage when many people already have chronic conditions.

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.

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.
