The human body needs sleep just as it needs oxygen, water and food to function at optimal level. Sleep deprivation has become an unrecognized epidemic as most people tend to experience some level of regular sleep disruption. We usually feel grumpy and foggy after a sleep deprived night but sleep deprivation affects almost everything about you - ability to lose weight, memory, health, looks, sex life etc.

Sleep deprivation kills your productivity and dumbs you down. A person who doesn't sleep enough is constantly sleepy, yawns too much, and is always irritable and tired during the day.
