Sleep disorders are of different kinds and the reason behind each disorder varies. This may include difficulty falling or staying asleep, falling asleep at inappropriate times, excessive total sleep time or abnormal behaviors associated with sleep. The brain regulates the circadian clock and the sleep-wake up patter. So when the body is deprived of sleep, it is the brain that we look up to, for treatment. Scientists have found that a protein found in muscles play an equal role in sleep regulation.
