According to studies, most of the adult population has experienced sleeplessness or insomnia at one point or another during their lifetime. Insomnia has been observed to affect around 30 to 50% of the public, 10% of whom suffers from chronic insomnia. By definition, the term insomnia is identified as “difficulty initiating or maintaining sleep or both” (Nabili, 2008, n. p. ). It may be due to either inadequate quantity or quality of one’s sleep. Basically, insomnia is considered as one of the most common complaints in the medical field.
It does not only make an individual feel unrefreshed after waking up, but the said condition also affects an individual’s capability to function during the day. Likewise, insomnia also affects a person’s mood or energy level, health, performance, and quality of living (Mayo Clinic Staff, 2009). Researches show that insomnia can be experienced by all age groups. In the case of adults, it was found that insomnia is prevalent among women than men, and the incidence tends to increase as a person ages.
It was also stated that such sleeping disorder is more common for people who are chronic alcoholics and mentally ill, as well as those in the lower socioeconomic bracket (Nabili, 2008). Because the amount of sleep in order to be considered enough varies from one person to another, insomnia cannot be defined as such by merely identifying the specific number of hours that a person sleeps; rather, it is categorized based on the duration of the problem.
If the symptoms of the condition last for less than one week, it is classified as “transient insomnia. ” Symptoms that are experienced between one to three weeks indicate “short-term insomnia,” while recurring symptoms for more than three weeks are already classified as “chronic insomnia” (Nabili, 2008).
