The circadian rhythm refers to a roughly 24-hour cycle of physiological processes undergone by all living creatures. The body’s natural sleep-wake cycle operates within this rhythm. This is why people tend to feel drowsy around the same times throughout the day – in the early afternoon and in the evening. Night shifts, staying up late, and international travel can all disrupt the body’s natural circadian rhythm.
