22 hours - the level of leukocytes rises, body temperature gradually decreases and the body asks for sleep.

23 hours - all muscles relax, but recovery processes start their own mechanism.

At 2 o'clock all the body systems rest. Only our liver works, which cleanses the body of toxins.

At 3 o'clock the body is fast asleep. There comes a complete calm: lowering blood pressure, body temperature, breathing and pulse are reduced.

At 4 o'clock the hearing becomes aggravated, and the sleeping person can wake up at any moment.
