While the necessities of life are food, water, and shelter, many forget that sleep is just as important to survival. Humans spend one third of their lives sleeping, but when something disrupts the ability to sleep, quality of life suffers. It's estimated that 50-70 million Americans don't get enough sleep on a daily basis. Research has found that chronic sleep deprivation has been associated with a range of health-related consequences. However, by understanding the brain and sleep correlation, researchers have been able to develop behavioral and medical treatment options that help people with sleep disorders live a more restful and healthy life.
