Sleep plays a crucial role for everyone. In our lifetime, about 1/3 of the time spent in sleep. Most of us need around 8 hours of sleep each night to function at our best.
Short sleep may represent a cause of ill-health, and long sleep is believed to represent more an indicator of ill-health. Therefore, people tend to spend a great deal of time worrying about sleeping problems and whether they have had the right amount of shut-eye to feel sufficiently rejuvenated. Conversely, animals do not have these problems.
