"Sleep is related to everything: your metabolism, your
physiology, your digestion, everything.
a. A natural periodic state of rest for the mind and body, in which the eyes usually close and consciousness is completely or partially lost, so that there is a decrease in bodily movement and responsiveness to external stimuli. During sleep the brain in humans and other mammals undergoes a characteristic cycle of brain-wave activity that includes intervals of dreaming.
b. A period of this form of rest.
c. A state of inactivity resembling or suggesting sleep; unconsciousness, dormancy, hibernation, or death.
