Let’s face it: sleep is just as important as eating and drinking water. Despite this, millions of people do not sleep enough and experience insane problems as a result.
The National Sleep Foundation (NSF) conducted surveys revealing that at least 40 million Americans suffer from more than 70 different sleep disorders; furthermore, 60 percent of adults, and 69 percent of children, experience one or more sleep problems a few nights or more during a week.
In addition, more than 40 percent of adults experience daytime sleepiness severe enough to interfere with their daily activities at least a few days each month — with 20 percent reporting problem sleepiness a few days a week or more.
On the flip side, getting a healthy amount of sleep is linked to:

Increased memory
Longer life
Decreased inflammation
Increased creativity
Increased attention and focus
Decreased fat and increased muscle mass with exercise
Lower stress
Decreased dependence on stimulants like caffeine
Decreased risk of getting into accidents
Decreased risk of depression
