A Healthy Sleep Should Consist of 4 or 5 Cycles
Healthy sleep basically consists of two phases: REM (Rapid Eye Movement) and Non-REM (Non Rapid Eye Movement). A normal sleep process has 4 or 5 cycles between REM and NonREM.
In the REM process, the physical state of brain activities is the most sedentary mode. The most important feature of REM sleep is rapid eye movements. In this way, dreams are also seen in this process. Pulse and breathing may be irregular and increase. There may also be irregular muscle movements.
In NonREM process, brain activities and metabolic rate are low. Pulse decreases. On the other hand, parasympathetic activity increases. The REM period is one-fifth of total sleep. In a normal sleep, the first REM occurs after 90-120 minutes on average. Sleep cycle and content can differ for most people. Because the sleep cycle and content may vary according to age.
