(6) Your heart rate, brain activity, and breathing slow down, and your body temperature decreases. (7) In the third stage, you transition between light sleep and the fourth stage of deep sleep. (8) It is during stages three and four, which are known as slow-wave sleep, that your body rests, replenishes its energy, and repairs itself. (9) Finally, about 90 minutes after you first fall asleep, the fifth stage of rapid eye movement (REM) sleep occurs. (10) Your brain is very active, but your muscles are paralyzed. (11) During REM sleep, you dream. (12) Throughout an average night, you move constantly from one stage to another in recurring cycles.
