sleep benefits
scientists have long debated precisely how sleep improves the brain performance, at the cellular level.one camp argues that sleep reduces the unimportant connections between neurons preventing brain overload. another camp maintains that sleep consolidates memories from previous day..sleep is an active process that reduces the activity in the brain. it allows the brain to recover from past experiences.during sleep the brain would not have the ability to continuously take in and store new information.it is this ability that helps us to forget the unwanted experiences and storing the pleasant ones.sleep relaxes our nerves, that are over worked during awakening state. it relaxes our mind and body in a natural way.

Sleep is very insistant drive. You can stay with food for couple of days, but human body cannot force itself to stay awake indefinitely. Researchers say there are different stages of sleep.
ReplyDeleteCertain areas of the brain have been found to be responsible for causing different sleep stages.
A common misconception is that the brain shuts down during sleep. In truth, parts of the brain may be even more active during different stages
of sleep.
Sleep may help the body recover from an active day and give it the chance to restore substances that are lost during the day. However, since simply resting the body without sleep does not fulfill the same function as sleep, it is thought that there is more to sleep than resting. sleepless nights make us very irritable & in active.
I agree with you Shantha..
ReplyDeleteFor starters, here is scientific evidence which shows that thinking, whether conscious or subconscious is an ongoing activity throughout the lifespan of a human being and sleep is not an exception. The brain is very much active during sleep
