Insomnia is a sleep disorder that occurs when a person has difficulty falling asleep. This condition makes the sufferer do not have the amount of sleep the body needs. This causes the physical condition of people with insomnia to not be fit enough to carry out activities the next day.
Â
This problem can occur in the short term (acute) to long term (chronic). In addition, sleep is an unconscious state that occurs naturally to allow the body to rest. During sleep, the body will go through cycles that alternate between fast eye movement sleep and non-rapid eye movement sleep.
Â
A person may go through four or five sleep cycles in one night. One sleep cycle lasts approximately 90 minutes. This cycle begins with the four stages of non-REM sleep, ranging from light sleep to deep sleep. Then, it is followed by REM sleep and it is at this stage that the dream process occurs.Â
