Diurnal animals, including humans, naturally sleep at night while remaining awake during the day. While this overall 24-hour rhythm of rest and activity is important, scientists are discovering […]
The Chronodiet: A Diet Based on Your Biology
Timing matters. That’s the premise of the Chronodiet. You’ve probably heard of the circadian rhythm, a term used in the science of chronobiology to describe the roughly 24-hour cycle followed by a wide variety of metabolic and physiological processes. When you sleep and when you wake up, the levels of hormones in your blood, brain […]
