Sleep is now characterized as a dynamic state controlled by specific and complex mechanisms. Even with all the medical and science advancements there is still no clear consensus about why sleep is necessary. One theory is that sleep allows the body time to repair itself on the cellular level. Other theories focus on what happens when people are sleep deprived. Everyone does agree, however, that sleep loss affects how we think, our mood, hormone balance, and our immune system. The research just has not figured out why.
