Sleep is the regular period in every 24 hours when consciousness is suspended and we become unaware of our environment. It is a natural state of rest for both the body and mind which helps keep us healthy. Whilst we sleep the nervous system is inactive, hormones are released into the bloodstream and the body has an opportunity to recuperate from the day’s activities.
