Healthy Aging
Evidence-aware exploration of factors associated with health and well-being across the lifespan. We focus on what research suggests and what remains uncertain.
Grounded in evidence
This page describes behaviors and factors studied in association with health across the lifespan. We do not claim to reverse aging, guarantee longevity, or promise specific outcomes. Aging is individual and influenced by genetics, environment, and access to care.
Movement
Regular physical activity is one of the most consistently studied factors associated with healthy aging.
Evidence: Well supported
Strength
Muscle strength and mass support independence, metabolic health, and bone health as people age.
Evidence: Well supported
Cardiorespiratory Fitness
Cardiorespiratory fitness is studied as a predictor of longevity and cardiovascular health.
Evidence: Well supported
Nutrition
Dietary patterns emphasizing whole foods, vegetables, and adequate protein are associated with healthy aging.
Evidence: Some supporting evidence
Sleep
Sleep quality and consistency are studied for their relationship with cognitive and metabolic health across the lifespan.
Evidence: Some supporting evidence
Social Connection
Social engagement and strong relationships are associated with well-being and health outcomes in older adults.
Evidence: Some supporting evidence
Cognitive Health
Research examines factors associated with cognitive maintenance, including activity, sleep, and lifelong learning.
Evidence: Emerging research
Language we avoid
- -Claims of "reversing" aging or biological age reversal
- -Promises to "live to 150" or guaranteed longevity
- -Framing aging as a disease to be cured
- -Overstating the role of any single supplement or behavior
