Circadian Rhythm and Intermittent Fasting for Healthy Lifespan

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 thoughtful timing of activity can improve energy and rest. He highlights that when we take medicines matters because the body’s response changes across the day. Travel and shift work challenge these rhythms, but simple habits with light exposure, meal timing, and sleep can ease the strain. Panda also describes ongoing efforts testing practical routines, including limited daily eating windows paired with light and activity strategies.
