Thanks to proper amount of sleep we are much less prone to depression, mood drops or excessive irritability. Healthy sleep translates into better control over emotions. It is worth mentioning here the issue, which is the regeneration of the brain. This organ regenerates both during the night rest as well as during a short nap during the day. Healthy sleep also helps to control body weight. It effectively improves memory ability and supports coordination and motor activities. It is at night that our brain organizes and consolidates all the information acquired during the day. Providing our body with an adequate amount of sleep, we contribute to the improvement of the functioning of the immune system.

Optimal amount of sleep
How long should I sleep to keep my body rested? It is difficult to answer this question unequivocally. It is an individual question. Sleep consists of 3 stages of NREM: N1, N2 and N3 and REM sleep. During the first two stages, our sleep is shallow. We fall asleep deeply only in the N3 stage, which is connected with biological rest. REM sleep is responsible for information processing and daydreaming. To get enough sleep, we need as much N3 and REM sleep as possible. Importantly, the 2 key stages of sleep do not occur one after the other. Instead, they are separated by the N1 and N2 stages. An adult usually has between 4 and 6 sleep cycles, each lasting between 80 and 120 minutes. The optimal length of sleep is said to be between 7 and 8 hours. Some people will feel rested after only 5 hours. Others, however, will need up to 10 hours of sleep
