What have you heard about sleep cycles?

Does it seem that nothing happens while sleeping with our body except its being in a passive state? But is it true? Probably all of us has experienced mornings when the number of sleeping hours seemed to be right, but getting up from hed was extremely difficult. Going deep into your sleeping cycles and the surroundings we spent our nights in may help you relax most effectively.

5 sleeping cycles

A  person experiences around 5 sleeping cycles per night. Each of them is inevitable and special having the task to restore the body’s tissues, muscles, bones, immune system, and other many more.

The first sleep cycle is meant to be a transitional one diving from an awake state to sleep. During this cycle, it is easy to wake up, even though the eyes are closed. The first cycle lasts extremely short - just a couple of minutes.

After the first one, our body reaches the second cycle that slows down the heart rate and drops down the body temperature. This cycle calms down our eyes and brain and is called non-REM phase. This part of the cycle brings us to the third and fourth cycles that are known as deep sleep.

During the deep sleep, our breathing slows down, gets deeper, and muscles completely relax. These two cycles are essential for the recovery of our body. The restoration of our body tissues is one of them. Thus, waking up a person that rests in the third or fourth cycle, is strictly not recommended as these two stages are the vital ones.

The fifth part of the cycle is a restless one called REM. During this one, the eyelids are closed, but the eyes move. It is the most intense part of sleep that lasts for an hour or more before the awakening. During restless sleep, the pulse and breathing accelerate, and the brain and dreams are the most intense ones.


If your sleep is one hour or an hour and a half too short, daily productivity will drop significantly. By the way, if a person wakes up and gets up in the middle of the cycle, more likely that he will be nervous.


  • Go to sleep at the same time every day.
  • Drink a cup of herbal tea before the sleep (but not too much to avoid waking up at night).
  • Have sex. During the process, endorphins are released, and they stimulate better sleep.
  • Ventilate the room before the sleep.
  • Have in mind that colors that are dominant in the bedroom also affect the quality of sleep. For example, according to various researches, blue and green colors make people feel calm.
