What’re stages of falling asleep?
You might think this is a funny question to ask. Do you really know anything about sleep? Sleep, an indispensable part of life, can alleviate people tired and promote the body's metabolism, which is very good for your health.
Experts suggest that the ideal average sleep time for humans is about 8 hours per day. Do you understand how to fall asleep? However, sleep is not just a state. We go through the following four stages in the process of falling asleep:
Stage 1: Falling asleep stage. In this stage sleeper will begin with drowsiness, gradually fall asleep and no longer remain awake. At this time, breathing slows down and muscle tension decreases, but sleepers are more likely to be aroused by external sounds or touches. Because it is not really sleeping, but a transitional period between wakefulness and sleep, which is usually referred to as dozing off.
Stage 2: Light sleep stage, or Mild sleep stage. Sleep at this stage belongs to light sleep or mild to moderate sleep. Sleepers are no longer easy to wake up with muscles are further relaxed.
Stage3: deep sleep stage.When the sleeper into a deep sleep state, their muscle tone disappeared and their muscles are fully relaxed. Sleepers are less likely to be awakened because their sensory function is further reduced.
Stage 4: Continue the deep sleep stage. This stage is the extension of the third stage, but not every sleeper can reach this stage, nor every sleep cycle can reach this stage. Some people can't reach this stage if they don't get enough sleep or only have the third and fourth stages of sleep for a very short time.
Rapid eye movement (REM) is a special stage after the end of the fourth stage. Rapid eye movement (REM) sleep occurs after the fourth stage. In this stage, eyeballs begin to move up and down rapidly. Blood flows to the brain to activate thoughts, so dreams begin to appear. After REM, the four stages of sleep are repeated again.
So how to get into a deep sleep quickly? Psychologists believe that, in fact, everyone can quickly enter the stage of deep sleep. For example, before you go to bed, you can breathe slowly for about 8 seconds. Then hold your breath for 5 seconds, and finally breathe out slowly. Don't be too urgent. After several repetitions, your mind begins to relax completely, so that you can quickly enter a deep sleep state.
