One of the most common and complicated rhythms of the human being is that of sleep. Individuals spend a large portion of their life in a sleeping state. There are many reasons why people sleep . Sleep is necessary in order for the body to “restore depleted reserves of energy, eliminate waste products from muscles, repair cells, strengthen the immune system, or recover physical abilities lost during the day”. With continuous and prolonged failure to sleep, the human body begins a downward spiral that may lead to illness or death in more severe cases. Thus, sleep is vital for adequate levels of functioning. However, many people suffer various types of sleep disturbance in which the ability to have restful sleep is disrupted. One such disturbance is called insomnia. The purpose of this paper is to discuss how insomnia is diagnosed and the types of treatment that are currently available.
Insomnia is a type of dyssomnia which refers to difficulties in sleeping an appropriate amount or in when the individual falls asleep . There are three major symptoms of insomnia. Any symptom alone can result in the inability to sleep. The first symptom involves the individual having difficulty going to sleep. In other words, he or she goes to bed but does not fall asleep. Another symptom of insomnia is not being able to stay asleep throughout the night. Here, the person is able to go to sleep, but he or she cannot stay asleep for the time necessary for the body to go through its many restorative processes. The last or third symptom is not achieving adequate sleep with regard to quality. Thus, the individual is able to sleep, but it is not restful. An individual can have any of the symptoms mentioned above and be diagnosed with insomnia, if it is determined that the sleep difficulties are of a chronic nature or pattern. In other words, if an individual only has a few days of not being able to sleep properly and then the pattern returns to normal, he or she may not necessarily have insomnia.
