Causes of insomnia
Insomnia is commonly defined as a sleep disorder or an individual’s difficulty falling asleep or maintaining sleep. Insomnia is interesting because it can be considered as being both an independent disorder on its own and a symptom of another disorder or condition. Because of these characteristics, Insomnia can be grouped into Two sub categories; primary and Secondary Insomnia. Primary Insomnia is a sleep disorder that is not the result of a medical, psychiatric or environmental cause, while Secondary insomnia is insomnia that is secondary to another condition, and thus is considered a symptom brought upon by the condition. Insomnia is a very serious condition that affects a lot of people around the world.
