Company Overview

Sleep is a behavioural state characterized by little physical activity and almost no awareness of the outside world. Most scientists think that sleep does something important — something vital for life, although research has not yet identified specifically what sleep does. Nevertheless, we all know when we need to sleep — we can feel this need. We also know when sleep has done its work — we feel rested and that we have slept enough. Another important feature of normal sleep is that it can end quickly. Although a sleeper may appear to be unconscious; unlike someone who is actually knocked-out, anesthetized or in a coma; a sleeping person can be easily awakened and can resume normal waking activity within a minute or two.
