What are the different phases of sleep?

scientists identified the different phases that your mind and body pass when you sleep. Five stages of sleep fall asleep, light sleep, two related phases of deep sleep and fast eye movement or REM while dreaming. If these periods are unusual, maybe because of sleep apnea, narcolepsy or somnambulism, you may be tired, oblivion or able to remember your dreams more clearly. Other decisive factors include breathing speed, heart rhythm, muscle activity, how easily you can wake up and eye rolling or REM. These are compared with your awakening when you emit beta wool with high frequency and low amplitude or intensity.

The first two phases of sleep are relatively light quality, called transitional periods. During the phase, relax your muscles, breathe deep and slowly, slowly override your eyes and often move your contacts for 5-10 minutes. You may experience hypnagogic phenomena where you are asking as if you were falling or seeing morphing pictures. Brain activity has a mixture of beta and theta waves with a slightly largerintensity. Phase II lasts 10-20 minutes with increasing theta waves that are synchronous, which means consistent.

In the III and IV stages, lasting 15-30 minutes at a time, almost all your muscles are paralyzed. Your body is rejuvenated by healing damaged tissue. Your brain mainly emits the delta waves that have low frequency and high amplitude. Phase III has less than 50% of the delta waves, while Phase IV has more than 50%, but otherwise they are the same. We feel good to relax after experiencing Delta sleep and it is difficult to awaken us during this period.

In the end, and as interesting as possible, Rem Sleep Stage V comes. Although we remained paralyzed, our brain suddenly behaves as if we were awake, with a unredictive dysnchronous beta wool. This phase, which represents 20-30% of the total sleep time, allows us to dream. Our eyes darts and meander in their drawers as if our dreams were in realthe life of life.

Health individuals are smoothly moving from the stage despite the phase in the beginning of the night. Then we return from REM to II, III, IV, back to REM, in 90 minutes cycles lasting the rest of the night. Scientists still do not understand why we eat, but people who have not touched dreaming are developing behavioral and mental problems, so it is obviously critical behavior.
