Insomnia is a sleep disorder characterized by an inability to sleep and/or inability to remain asleep for a reasonable period. Insomniacs typically complain of being unable to close their eyes or "rest their mind" for more than a few minutes at a time.
Sleep disorderBoth organic and nonorganic insomnia constitute a sleep disorder. It can be caused by fear, stress, anxiety, medications, herbs, caffeine, depression, or bipolar disorder and sometimes occurs for no apparent reason. An overactive mind or physical pain may also be causes.
Finding the underlying cause of insomnia is usually necessary to cure it. Insomnia can be common after the loss of a loved one, even months or a year after the death, if they are not grieving correctly (pretending they are over it when they are not). It very often occurs when the person has a lack of food or not enough variety of foods (such as eating one food over and over again).
Statistics for insomniaAccording to the U.S. Department of Health and Human Services, approximately 60 million Americans suffer from insomnia each year. Insomnia tends to increase with age and affects about 40 percent of women and 30 percent of men.
The average American gets 7 hours of sleep, instead of the 8 to 10 hours recommended by doctors. Children however are recommended more than 8 hours.
