Introduction to sleep
Sleep is the natural state of rest during which a person’s consciousness is suspended. When a person is sleeping, their muscles are relaxed and there is no voluntary activity. The pulse will slow down and the respiratory movements will be less frequent, but more profound. There will also be less blood in the cerebral vessels.
