clock gene

Clock genes are specific genes that control the body's internal clock, or circadian rhythm, which regulates daily cycles like sleep, wakefulness, hormone production, and body temperature. These genes produce proteins that interact in feedback loops, turning on and off over about 24 hours to synchronize biological processes with the day-night cycle. Essentially, clock genes help our bodies know when to be alert, when to rest, and when various bodily functions should occur, ensuring our physiology aligns with the environment’s rhythm for optimal health and performance.
