Importance of Sleep

Sleep is an altered state of consciousness wherein the individual is relaxed , at rest and not conscious of the external environment , however the body is still actively functioning .

able to sleep well are more alert , active , concentration is at its peak and in sum healthier than those who have not slept well . Moreover , scientists have found that during sleep , the body is able to regenerate and renew itself by the repair and growth of body tissues . During sleep , we spend less energy than being awake , and it seems that this is when the body is able to heal itself . Our body has a reserved amount of energy that it uses as fuel during the day , this reserve is used up when we are active and awake , however when we are asleep , this reserve is again filled by the body to prepare for the next day . Thus , when a person is not able to sleep , he /she feels tired , sluggish and fatigued . Sleep is also necessary for growth (Myers , 2004 studies have shown that the growth hormone is activated during sleep as well as the development of bones in infants and young children . Which is why , babies and young children need more sleep than adults . It has also been said that it is during sleep that the brain encodes the information it has received to memory (Myers 2004 ) as suggested by the intense activity of the brain during sleep which is why those who lack sleep are often forgetful and has shorter attention span
