Why do we sleep?

Sleep is an essential function that enables your mind and body to recharge and restore. Healthy sleep leaves you feeling refreshed and alert when you wake up.

Healthy sleep also helps the body function properly and fight infection.


Sleep deprivation can negatively impact every cell and organ system in the body.

A significant library of research over the past several decades has revealed many of the critical biological requirements of achieving the right amount of deep, restful sleep. Nevertheless, a great deal of new research will certainly provide even greater insights in the coming years. Perhaps as research reveals more, societal attitudes about sleep and common sleep disorders will also evolve.

Sleep disorders are prevalent and can lead to a variety of health concerns.

The average adult requires between seven and eight hours of sleep. Interrupted or poor sleep habits can lead to fatigue, poor decision-making and increased risk of accidents. Additionally, it is becoming more and more evident that sleep deprivation can lead to a variety of chronic health problems including pre-mature death.
