Insomnia is characterized by an inability to sleep and/or 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. Both organic and nonorganic insomnia constitute a sleep disorder [http://www3.who.int/icd/currentversion/fr-icd.htm?gg40.htm+g47. It is oftenly caused by fear, stress, anxiety, medications, herbs or caffeine. An overactive mind or physical pain may also be a cause. Finding the underlying cause of insomnia is usually necessary to cure it.

Types of insomnia


Three different types of insomnia exist. Insomnia may be classified as transient, acute (short-term), and chronic. Insomnia lasting from one night to a few weeks is referred to as transient. This is generally the case for most people, as one often suffers from jet lag or short-term anxiety. If this form of insomnia continues to occur from time to time, the insomnia is classified to be intermittent. Acute insomnia is the inability to consistently sleep well for a period of three weeks to six months. However, after this time, the person does not experience insomniatic episodes. Insomnia is considered to be chronic, the most serious, if it persists almost nightly for at least a month, and sometimes longer.

Common causes of insomnia


A person can have primary or secondary insomnia. Primary insomnia is sleeplessness that is not attributable to a medical or environmental cause. Secondary insomnia means that a person is having sleep problems because of something else, such as a health condition, an example of which would be generalized anxiety disorder.
