What is Insomnia?
Insomnia is a sleep disorder in which a person has trouble falling asleep and, in many cases, cannot stay asleep. It is also characterized by the inability to achieve a deep, restful sleep for long periods of time. While many people can fall asleep and maintain a REM state for several hours, they cannot achieve the deep, non-REM sleep needed that allows the body to begin to heal itself. Without this deep sleep, the body can begin to deteriorate physically, resulting in a higher risk of injuries and muscle weakness. Individuals who live fast-paced, stressful lives often complain about having insomnia or not being able to get enough sleep.
