Sleep is important to our body as food and water, though most of us don’t consider it to be essential. Sleep is a necessity and not a luxury. The psychological state called fatigue can occur as often as we suffer from insufficient sleep.
Phase of sleep
The Non-Rapid Eye movement (non-Rem) and Rapid Eye movement.
The Non-Rem: this has four stages 1. TRANSITION TO SLEEP lasts about five minutes: eyes move slowly, under the you are easily awakened. 2. LIGHT SLEEP: the 1st stage is true sleep lasting from 10 to 25 minutes, where the eye movement stops, and heart rates slowly, body temperature reduces, 3. DEEP SLEEP: you are difficult to awaken and if you are, you feel groggy and disoriented. 4. MORE INTENSE DEEP SLEEP: the deepest stage. Brain waves are extremely slow; blood flow is directed away from the brain and towards the muscles restoring physical energy.
Rem: dream sleep. You enter this stage 70 to 90 minutes asleep. It’s a stage where dreaming occurs. Eyes move rapidly, breathing is slow, heart rate and blood pressure increase; arm and leg muscles are paralyzed.
IMPORTANCE OF DEEP SLEEP AND REM

Science has proven that sleep is one of the most essential things needed to keep the average individual healthy and stable. Without the “healing” powers of sleep, our minds and our bodies can be easily affected because of the constant feeling of fatigue. The human body thrives on the energy that sleep ensues in our bodies every night. While the average individual is to sleep approximately eight hours a night, realistically speaking, getting that much sleep on a regular basis is something to strive for.

There are four stages of Non-REM sleep. In the first stage, you can be awakened without difficulty but it may leave the person feeling as if he or she has not slept. In the second stage, the body temperature and heart rate drop. At this point, your body gets ready to enter deep sleep. The last two stages are deep sleep stages, with the fourth being more intense. These stages are known as slow-wave, or delta, sleep. If woken up, you may feel disoriented for a while. REM sleep is described as sleep where rapid eye movement occurs. It is also known as “active sleep.” It is during REM sleep that we being to dream. On average a person can have 3 to 5 periods of REM sleep per night. REM sleep is characterized by a number of other features including rapid, low-voltage brain waves, irregular breathing and heart rate, and involuntary muscle movement. Sleep provides the human body with the energy it needs to keep on going. During the state of sleep, the body’s metabolic processes slow down and energy consumption is kept to a minimum.

Sleep is categorized into stages of a cycle between REM sleep and NREM sleep. NREM sleep is further divided into four stages: stage 1 (a light sleep period), stage 2 (a consolidated sleep period), and stage 3 and 4 (slow wave sleep periods). This is followed by stage 3, stage 2, stage 1, and a REM period. In normal adults, a cycle will last about 1.5 hours. The length and content of sleep cycles change throughout the night as well as with age. Sleepwalking generally occurs during the first third of the night (between 11 p.m. and 1 a.m.)During the slow wave NREM sleep stage. High delta activity within the brain usually accompanies slow wave NREM sleep, and when 20–50% of all activity is delta activity, stage 3 is scored. When delta activity reaches 50% or higher, stage 4 is scored. Usually, if sleepwalking occurs at all, it will only occur once in a night.…
