Aging and Senior Health (Audio)

Sexual health is an important part of healthy aging and offers a useful way to understand how well-being can change without disappearing in later life. Annie L. Nguyen, Ph.D., M.P.H., UC San Diego, explains how sexual interest, sexual activity, and sexual satisfaction follow different patterns as people age. Nguyen examines research on health status, relationship context, and gender differences,...

How fast are you really aging, and what could that mean for brain health? Aladdin H. Shadyab, Ph.D., explores the gap between chronological age and biological age, and why that difference matters for long-term health. Shadyab describes tools that use information from blood to estimate how quickly the body is aging, including approaches that look beyond the body as a whole to consider aging in...

Circadian timing shapes how we sleep, feel, and function each day. Satchidananda Panda, Ph.D., Salk Institute, describes what the ideal circadian rhythms of a day look like. Dr. Panda explains that keeping daily light, meals, movement, and sleep in step with the body’s internal clock supports alertness, metabolism, and recovery. Series: "Stein Institute for Research on Aging" [Health and...

How you time light, meals, and sleep can reset your internal clock. Satchidananda Panda, Ph.D. explains why morning light sharpens alertness, evening dimness protects melatonin, and consolidated sleep supports brain “detox.” Clear, practical takeaways you can use tonight and tomorrow morning.

How much exposure to daylight is recommended for optimal health? Satchidananda Panda, Ph.D., Salk Institute, answers this question and many more on the therapeutic nature of light. Dr. Panda also discusses indoor lighting considerations in order to simulate day/night cycles. Dr. Panda explains that the use of lighting isn't just for safety and convenience but also for one's health. Series: "Stein...

Biological resilience underpins healthy aging, and Anthony Molina, Ph.D., investigates how people resist, adapt to, and recover from age-related stressors. Molina defines three domains of resilience linked to aging and studies “life course” resilience using the Rancho Bernardo Study, a longitudinal cohort that starts in 1972 and tracks cognitive, sensory, physical function and comorbidities. His...

Circadian timing shapes how we sleep, feel, and function each day. Satchidananda Panda, Ph.D., Salk Institute, explains that keeping daily light, meals, movement, and sleep in step with the body’s internal clock supports alertness, metabolism, and recovery. Panda notes that evening light and late eating can make it harder to fall asleep and may work against healthy glucose control, while...

Psychological resilience in later life examines how older adults adapt after adversity and cultivate everyday practices that sustain well-being and purpose. Elizabeth W. Twamley, Ph.D., introduces and guides a discussion on mental health and resilience among older adults. Ellen E. Lee, M.D., characterizes resilience as dynamic learning oriented toward flourishing and urges a low threshold for...

Cognitive resilience grows from small, consistent habits that keep the brain adaptable. Fadel Zeidan, Ph.D., frames mindfulness as mental training that improves attention, processing, and the way people relate to pain. Erin E. Sundermann, Ph.D., underscores modifiable pathways to healthier aging, highlighting movement, social connection, hearing support, and lifelong learning as mutually...

Targeting the biology of aging offers a path to stronger resilience and longer health. John C. Newman, M.D., Ph.D., explains that aging arises from measurable cellular processes, often called hallmarks of aging, including changes involving mitochondria, stem cells, cellular senescence, inflammation, and protein quality control. Newman describes how basic science in model organisms reveals...
