Sleep is the state of natural rest observed in most mammals, birds, fish, as well as invertebrates such as the fruitfly Drosophila. It is characterized by a reduction in voluntary body movement, decreased reaction to external stimuli, an increased rate of anabolism (the synthesis of cell structures), and a decreased rate of catabolism (the breakdown of cell structures). In humans, mammals and many other animals which have been studied, such as fish, birds, mice and fruitflies, regular sleep is necessary for survival. The capability for arousal from sleep is a protective mechanism and also necessary for health and survival. Sleep is not synonymous with unconsciousness.

At certain stages of sleep brain waves slow down a lot, but in REM (Rapid Eye Movement) The last stage of sleep, where we dream, the brain is almost as active as when awake.
During the 3rd and 4th stages of sleep, the brain moves bloodflow from the organs and uses it to restore repair muscle tissue and heal the body.

i'm a company believer that sleep is for replenishing no longer purely your actual skill ranges, yet your psychological skill ranges besides. Do you ever observe which you would be able to bypass to mattress indignant or unhappy or purely undeniable twisted and awaken feeling clean and constructive lower back in the morning. Sleep is whilst our brains technique. And dreaming i assume is a time for our suggestions to "loosen up"in an attempt to chat. it is the reason infants sleep plenty, in part because of the fact they are so little, yet in addition because of the fact they are continuously gaining knowledge of whilst they are wakeful and their brains could desire to technique each and every of the hot archives.

No your brain is amazingly busy it doesn't even slow down and in children while they sleep their brain is learning more than any other time through the day.

yes, brain sleeps. BUT not completely. After we sleep our brain becomes semi-consious and does the duty. We call it as sub-consious brain which takes care of regular bodily activities while u in sleep.
