Dr. Satchin Panda, a circadian biology pioneer from the Salk Institute, uncovers how aligning your eating and exercise with your body’s natural rhythms can boost health and cognition. He emphasizes the importance of time-restricted eating, especially for shift workers. Dr. Martin Moore-Ede, a former Harvard professor, highlights the dangers of blue light exposure, linking it to disrupted sleep and obesity. Together, they shed light on how modern lifestyles are misaligning our circadian rhythms, urging for better light exposure and healthier eating patterns.

Episode notes

INSIGHT

Timing of Eating

When we eat is as crucial as what we eat, impacting our metabolic health and disease risk.
Our bodies operate on a 24-hour clock, influencing digestion, cell repair, and hormone production.

INSIGHT

Late-Night Eating Consequences

Regularly eating late at night disrupts insulin production and melatonin secretion.
This can lead to elevated blood glucose, increased fat storage, and weight gain.

ANECDOTE

Time-Restricted Eating Benefits

Many people consider themselves healthy and question the need for time-restricted eating.
Dr. Panda's study showed improved sleep, reduced hunger, and increased energy in participants.

We used to think that the circadian rhythm only affected sleep. However, emerging science shows it’s deeply connected to metabolism, cognition, chronic disease risk, and many other critical aspects of health. Our biology is designed to function in harmony with the natural light-dark cycle, but modern society has significantly disrupted this balance.

Today on The Dhru Purohit Show, we bring you a special compilation episode featuring Dhru's conversations with leading experts on the critical role circadian rhythms play in our health and well-being.

Dr. Satchin Panda delves into his groundbreaking research on circadian biology, revealing how leveraging your circadian rhythm can significantly improve sleep, reduce the risk of chronic diseases, and enhance cognitive function. He also shares how time-restricted eating, exercise, and light exposure can help program your circadian rhythm, with a special focus on the importance of these tools for shift workers.

Dr. Moore-Ede discusses the dangers of chronic blue light exposure and its profound impact on health, highlighting research that reveals how it disrupts circadian rhythms. He also examines the connection between light exposure and obesity and explains why these risks remain underrepresented in mainstream media.

Dr. Satchin Panda, a professor at the Salk Institute and founder of the UC San Diego Center for Circadian Biology, is a leading researcher in circadian biology.

Dr. Martin Moore-Ede, a former Harvard Medical School professor and expert in circadian rhythms, has conducted groundbreaking research on light's role in regulating sleep-wake cycles and overall health.
