With Dr. Satchin Panda
& Dr. Martin Moore-Ede

We used to think 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

Dr. Panda is pioneering circadian biology research. He is a professor at the Salk Institute for Biological Studies, a Pew Biomedical Scholar, founder of the UC San Diego Center for Circadian Biology, and recipient of the Julie Martin Mid-Career Award in Aging Research. Dr. Panda has spoken at conferences around the world about his work on circadian rhythms and diabetes, including Diabetes UK, the American Diabetes Association, the Danish Diabetes Association, and the professional diabetes societies of Europe and Australia.

 
Dr. Martin Moore-Ede

Dr. Martin Moore-Ede is a highly respected expert in circadian rhythms and light’s impact on our health. As a former professor at Harvard Medical School, he has conducted extensive research on the role of light in regulating our sleep-wake cycles and overall well-being. Dr. Moore-Ede’s groundbreaking work includes the discovery of the suprachiasmatic nucleus, a crucial biological clock in the brain that controls our daily rhythms. He has contributed significantly to our understanding of how blue light, particularly from LED sources, can disrupt our circadian rhythms and lead to various health issues, such as obesity, diabetes, and even breast cancer. With his expertise, Dr. Moore-Ede advocates for adopting better lighting practices, emphasizing the importance of using the right type of light at the right time to optimize employee health and productivity.
