So what is the right amount is mainly based on the recovery of mental and physical strength. People's sleep can be divided into slow eye movement sleep and rapid eye movement sleep. Intensive REM sleep occurs in the last stage of REM sleep in memory storage, tissue maintenance, information sorting and new learning and performance, while REM sleep usually occurs in the later part of the 8-hour sleep period. However, most of us don't get enough sleep, which not only reduces the quality of life, but also may cause diseases.
