Resumo da Biografia

Norepinephrine as well as orexin keep some parts of the mind active while we are awake. Various other natural chemicals that form sleep and also wakefulness include acetylcholine, histamine, adrenaline, cortisol, as well as serotonin. Stage 1 non-REM rest is the changeover from wakefulness to sleep. During this brief period of relatively light rest, your heart beat, breathing, and eye activities slow-moving, as well as your muscular tissues unwind with occasional twitches. Your brain waves start to slow down from their daytime wakefulness patterns.
