“Life is like a deep sleep of which love is everything.”-Alfred de Musset
The sleeping cycle is composed of four stages and two categories. The two categories mentioned include REM and non-REM. REM or light sleep pertains to the early stage of sleep, which is accompanied by rapid movement of eyes and low muscle tone while non-REM or deep sleep refers to non-rapid eye movement and accompanied by slow brain waves.
non-REM or deep sleep is responsible for consolidating memories, learning new knowledge, and processing emotions. Moreover, it also takes care of biological balance by recovering the body and boosting both the immune system and metabolism as well. Thus, deep sleep is considered the most important among all the sleep cycle stages.
According to NCBI, deep sleep accounts for the first 13-23% of an entire sleep cycle, so in an eight-hour sleep cycle, 62-110 minutes would be considered deep sleep.
