Sleep deprivation is universal and so common. Sleep deprivation affects millions of people allover the world due to the high paced mechanical lifestyle, causing a lack of time to get the sleep we always wanted. Sleep deprivation may also be due to genuine sleep disorders, either due to some psychological problems or chronic insomnia. Most of us are not really taught how to sleep and rest better in our daily life. As a result the total cost in lost man hours, production and precious lives are so huge and often it defies human imagination. Sleep deprivation means an overall deficiency in the necessary amount of sleep, that a person is supposed to have in a day. Sleep deprivation may occur due to diurnal changes in the mind and body, or also due to extreme insomnia. It may also be artificial, being induced by another person or your own baby. Sleep deprivation is considered very dangerous and very unhealthy and as such must not be tried by any person. However, in some clinical cases of psychology, deprivation of sleep may help patients with mental illness. Sleep deprivation causes serious changes in body physiology and mental composure; lack of sleep may result in irritability, vision impairment, stuttering speech, momentary loss of reasoning, confusions, hallucination and nausea. A consistent lack of sleep or sleep deprivation may result in a condition known as fatal familial insomnia and chronic dementia. Sleep deprivation also leads to people becoming overweight and obese, and such physical transformation will even

tually lead to other medical risks. Recent research on sleep deprivation has indicated that sleep deprivation shows the same hazardous effects as being in a drunken state. Sleeping for less than 6 hours a night can affect your coordination, judgment, mental alertness and reaction. Sleep deprivation will also lead to muscular deficiencies, when the mind gradually looses its control over the muscle, which ultimately leads to Muscular-skeletal diseases. Sleep deprivation may occur in cases of college going young adults, when they try hard to wake during night to study for their tests and examinations. A prolonged loss of sleep may result in daytime lethargy and laziness, which eventually leads to poor academic performance. Late night parties and bashes will cause a serious loss in the total sleep budget, as many people invariably get drunk and loose sleep in the process. Sleep is a natural gift provided to maintain a clean body rhythm and accurate biological clock; an intrusion in such a natural rhythm is always undesirable and disadvantageous to our body.
