Definition of Sleep-
So why do humans sleep? The very first organisms recognize the necessity of sleep for two main reasons: preservation and Restoration. Humans have a biological impulse to sleep as it is a safe haven from the tumult of the world and from the dangers of the night. Primary instinct tells us to fall asleep each night to attain a sense of security.
What you should know about sleep-
It is important to recognize the stages of sleep. There are 5 stages of sleep that on encounters as the night progresses. An electroencephalograph can be used to record the electrical activity on the brain's surface and is especially important the the study of the brain' stages of sleep. In stage 1 of sleep humans breathing is slowed and it is still easy to arouse an individual in this stage of sleep. Everyone has those grandparents or a father who insist that they were, "watching the television", even though they were in this stage of sleep. By the time a person has reached stage 2 of sleep, brain waves slow and by stage 3 a person experiences slow wave sleep. It is common for many adults to experience these first stages of sleep over the following stages. Stage 4 of sleep is highlighted by a deeper more intense wave cycle slowing. These stages (1-4) are all considered N-REM (non-REM sleep) and by the time stage 5 is reached REM sleep has begun. This stage id viewed commonly among researchers as the most important stage in a child's development and is constituted by rapid eye movement and dreaming. The term "paradoxical sleep" termed by William Dement is exposed in this stage. This stage of sleep, in terms of wave pattern, is similar to when a person is awake and pulse and breathing quickens.
Feeling the effects of sleep deprivation-
-increases the risk of accidents
-memory lapses or loss
-impaired moral judgement
-symptoms similar to ADHD
-impaired immune system
-risk of diabetes type 2
-increased heart rate variability
-risk of heart disease
-decreased reaction time and accuracy
-risk of obesity
There are so many other consequences of sleep deprivation but these are some of the more known effects. It goes to show how influential sleep is in one's life. Specifically sleep deprivation in rats has been studied and research demonstrates that complete sleep deprivation leads to failure to thrive, excessive food intake with decreased weight, a loss of hair and skin abnormalities, hyperactivity, and finally the death of all rats at day 22.
