Every night, you are in the loop

Four different sleep stages

Several times-the three stages of REM (rapid eye movement) and non-REM sleep.this is

What happens at each stage.

Non-rapid eye movement

Phase 1:
When you doze off for the first time, your body will go through a few minutes to transition from awake to sleep, because your brain waves begin to slow down from awake mode. This is a very light sleep, when your heartbeat, breathing and eyes relax. Some people experience muscle twitches when they slow down and prepare to rest and sleep.

second stage:
When you fall asleep, your body enters a light sleep phase. This transitional period occurs when your body continues to relax further. In addition to more relaxed muscles and slower breathing and heartbeat, body temperature drops and eye movements stop.

Phase 3:
In order to feel refreshed every morning, your body needs deep sleep. At this stage of sleep, your body is in its most relaxed state, so it is more difficult to be awakened. During this sleep phase, your body releases hormones, performs tissue growth and repair, and restores energy.

Although most dreams do occur at that stage, you can dream at any stage of sleep.

In normal sleep, you will cycle through each stage multiple times. Although you spend more time in stage 2 than in any other stage, your body experiences a longer stage 3 sleep time in the first half of the night, and as the morning approaches, your REM sleep time will be longer, Deeper.The time you spend in REM sleep
