By definition, medical-dictionary. thefreedictionary. com states that sleep is a natural periodic state of rest for the mind and body, in which the eyes usually close and consciousness is completely or partially lost, so that there is a decrease in bodily movement and responsiveness to external stimuli. a.

These intervals of dreaming can be divided into two categories. i. NREM sleep and REM sleep. There are five stages of sleep. 1. The first four stages of sleep are NREM sleep. NREM sleep is the non-rapid eye movement sleep; during the first stage of this type of sleep, you are in a battle of going to sleep but staying awake. In like the fourth stage, you really notice how NREM sleep is. NREM is the deep, dreamless period of sleep during which the brain waves are slow and of high voltage, and autonomic activities, such as heart rate and blood pressure, are low and regular.
REM sleep is the fifth stage or the last stage and is exactly opposite of NREM. This type of sleep is associated with dreaming, mild involuntary muscle jerks, and rapid eye movements. It usually occurs three to four times each night at intervals of 80 to 120 minutes, each occurrence lasting from 5 minutes to more than an hour. b. Most people tend to want to go to sleep when they are bored for example i.

Getting more sleep will help you remember and process things better. c. A third thing is that sleep may help you loose weight. i.
