Aging Brain More Vulnerable to Even Mild Oxygen Deprivation

New research shows that even mild, prolonged exposure to low oxygen levels can significantly disrupt the blood-brain barrier (BBB) in aging brains. Using mice aged 2 to 23 months, scientists found that older mice experienced 4–6 times more BBB breakdown than younger mice under similar hypoxic conditions.

Cannabis Use Among U.S. Seniors Has Surged 46% in Just Two Years

Marijuana use among U.S. adults aged 65 and older has climbed to a record 7%, up nearly 46% from 2021 to 2023. The trend is especially pronounced among college-educated, married, and higher-income individuals, particularly women.

Midlife Caffeine Intake Linked to Healthy Aging

A long-term study following nearly 50,000 women over 30 years found that drinking caffeinated coffee in midlife is linked to healthier aging. Women who drank regular coffee were more likely to avoid chronic disease, cognitive decline, and physical impairment later in life.

Long-Term Weight Loss in Midlife Tied to Lifespan Benefits

A long-term study of 23,000 adults from Finland and the UK has found that overweight individuals who lost just 6.5% of their body weight in early midlife and maintained the loss enjoyed significant health benefits over decades. The study, spanning 12 to 35 years, is one of the first to link modest, sustained weight loss with lower mortality outside the context of diabetes prevention.

Decoding Brain Aging: A 10-Year Study Opens Data for Discovery

A decade-long brain health study has released its full dataset, offering rare longitudinal insights into how cognition and brain structure change across adulthood. The Dallas Lifespan Brain Study tracked nearly 500 individuals from age 21 to 89 over three timepoints using brain scans, cognitive tests, and health surveys.

Social Engagement Linked to Longer Life

A new study shows that older adults who stay socially active have a significantly lower risk of death over four years compared to those with low social engagement. The research, involving over 2,200 individuals aged 60 and older, found that high engagement in activities like charity work, grandparenting, and club participation reduced mortality risk by 42%.

Vitamin D May Slow Biological Aging

New results from the VITAL randomized trial show that daily vitamin D3 supplementation helps preserve telomere length in older adults, potentially slowing a key biological aging process. Telomeres are protective caps on chromosomes that shorten with age and are associated with chronic diseases.

Plant-Based Diet Could Turn Back Biological Aging

A new study suggests that eating more plant-based foods rich in natural compounds called methyl adaptogens—like turmeric, berries, garlic, and green tea—may slow the body’s biological aging process. Researchers analyzed DNA methylation, a cellular marker of aging, in men aged 50 to 72 who followed a nutrient-rich, plant-forward lifestyle.

Want to Live to 115? Here’s What Research Says You Should Do

New insights from longevity research suggest that lifestyle—not just genetics—plays a vital role in living a longer, healthier life. While rare individuals like 115-year-old Ethel Caterham may benefit from exceptional genes, research shows that physical activity, diet, sleep, and stress management are key factors that can significantly influence lifespan.

Sitting for Hours May Shrink the Brain

Prolonged sedentary behavior in adults over 50 is linked to cognitive decline and brain shrinkage in regions vulnerable to Alzheimer’s disease. Even among those who exercise regularly, spending more time sitting was associated with worse cognitive outcomes.

Midlife Cortisol Levels Linked to Alzheimer’s Risk

A new study finds that elevated cortisol levels in midlife are linked to increased brain amyloid deposition—a key marker of Alzheimer’s disease—specifically in post-menopausal women. Researchers tracked 305 cognitively healthy individuals over 15 years and discovered that high cortisol predicted amyloid buildup later in life, but only among women who had gone through menopause.

Diverse Social Ties Boost Health in Aging

A decade-long study of over 1,500 older adults reveals that socially enriched networks—marked by diverse and active relationships, are strongly linked to better health outcomes later in life. In contrast, those with restricted networks, often limited to family and shaped by isolation, reported significantly worse health and were less likely to improve their social ties over time.
