Dr. Satchin Panda, a leading expert on circadian rhythms and time-restricted eating from the Salk Institute, dives deep into the body's biological clock. He shares how aligning light exposure with our routines can vastly improve sleep quality and cognitive performance. Fascinatingly, he discusses the relationship between melatonin, insulin secretion, and metabolism. Dr. Panda also highlights how time-restricted eating can bolster health and shares innovative strategies for managing the impacts of shift work and modern living on our circadian cycles.

Circadian Rhythms Defined
Circadian rhythms are daily timetables for bodily functions, repeating every 24 hours.
These rhythms affect organs, cells, hormones, and brain chemicals, influencing sleep and other processes.
insights INSIGHT
Peak Cognitive Performance
Cognitive performance peaks during specific times, influenced by the circadian rhythm.
Adequate sleep is crucial for clear thinking, as caffeine only provides temporary alertness.

Satchin Panda
The Circadian Code by Dr. Satchin Panda outlines the importance of the body's internal clock and how it affects various physiological processes. The book explains how every organ and cell in the body has its own circadian rhythm and how these rhythms can be optimized through lifestyle changes such as time-restricted eating, proper sleep schedules, and synchronized exercise. Dr. Panda's methods aim to prevent and alleviate chronic ailments like diabetes, cancer, and dementia, as well as digestive conditions. The book provides a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology to align with the body's natural rhythm[1][3][4].
Dr. Satchin Panda
Dr. Satchidananda (Satchin) Panda is a professor in the Regulatory Biology Laboratory at the Salk Institute for Biological Studies.
Dr. Panda’s work focuses on chronobiology, the study of the day-night cycles that drive the multifaceted activities of the human body, using genetic, genomic, and biochemical approaches. He is an expert on circadian rhythms and a pioneer in the field of time-restricted eating. A priority for Dr. Panda when designing his studies is to identify strategies that positively impact public health.
