What is the brain plasticity theory of sleep. This internal clock oversees circadian rhythms, or bodily functions that fluctuate over each day, such as metabolism, body temperature, and hormone release. For example, both body temperature and caloric demand decrease during sleep, as compared to wakefulness. However, 40-50 percent of Americans do not get enough sleep every night (Information on Insomnia, n.d.).

Defines sleep as "the natural state of rest during which your eyes are closed and you become unconscious." there are many reasons as to why sleep is needed, including the inactive theory, energy conservation, and restoration theories. That function is sleep and it is a very vital component that us humans love to neglect ourselves of. The energy conservation theory suggests that the primary function of sleep is to reduce an individual's energy demand and expenditure during part of the day or night, especially at times when it is least efficient to search for food. These phases develop continuously, from stage 1 to REM and then back to stage 1. According to this view, a reduction in the sensory stimulation to the brain is responsible for the onset of the sleep state. We tend to think of sleep as a time when the mind and body shut down.

They have examined, for example, what happens when humans or other animals are deprived of sleep. Proponents of energy conservation theory believe that sleep's primary job is to minimize an individual's energy requirements and expenditure during certain times of the day or night .

Through natural selection, this behavioral strategy presumably evolved to become what we now recognize as sleep.A simple counter-argument to this theory is that it is always safer to remain conscious in order to be able to react to an emergency (even if lying still in the dark at night). National Library of Medicine Afforestation alone is difficult to offset carbon .
