We can not prepare sleep for loss of consciousness, but a change of consciousness. There is a lot of research that still deals with research the main function of sleep, but there is a common belief That sleep is a natural phenomenon that occurs to reorganize brain activity, and other vital functions in living organisms. In this article we will introduce you to the stages of sleep in detail.
Stages of sleep
Daydream stage
At this stage, man begins to think about many things he sees as dreaming of daydreams. It is a transitional phase between wakefulness and sleep, and the brain during this phase releases many of theta waves, which affect all other waves of the brain, thus slowing down, Human beings have strange sensations, such as a sense of sudden fall because of the rapid relaxation felt by all members of the brain, and this stage remains for ten minutes can be shortened, or prolonged according to the sense of each person before his sleep.
Stage spinner sleep
Delta phase, this period extends for twenty minutes where the brain begins to issue rapid and active waves, known as (Sleep spins) , Here body temperature decreases with a slowdown in heart rates.
Delta phase waves
In the Delta wave phase the brain releases very slow waves called the (Delta waves) , A transition between light sleep and deep sleep.

Delta waves begin to control all muscles and cells in the body, slowing down to a low degree. The body begins to enter the deep sleep phase, which lasts for 30 minutes and may increase or decrease.
Deep sleep stage
The deep sleep phase is the most complex phase of the previous sleep, with most of the dreams seen during sleep, as well as a phenomenon that is still puzzling scientists, the phenomenon of rapid movement of REM eyes, where the activity of the brain during the dream and can move some The reason for this phenomenon is the result of the dreams themselves, the mind portrays to the human being that he sees a group of images that walk inside, as if real, and scientists see the possibility of seeing dreams in the first and second stages, and There is a possibility that you will not remember when you wake up, so the stage of true dreams is (Deep sleep stage) .
