Insomnia is a subjective disorder and is usually long term. Insomnia affects up to 1/3 of adults in Western countries, women more than men. There are many different types of causes.
Circadian rhythm disorders are sleep disorders in which there is a mismatch between circadian rhythms and the required sleep-wake cycle. Parasomnias are unusual episodes or behaviors occurring during sleep. Many of them affect children which they usually outgrow. Sleep apnea and restless leg syndrome are two other sleep disturbances that I will cover in another hub.
It is important to treat insomnia because the condition causes decreased quality of life; is associated with impaired functioning in many areas; and leads to increased risk for depression, anxiety, and possibly cardiovascular disorders. The goal of course, is to lessen the anguish of living with insomnia and always being tired. I made a list of suggestions of things you can do to help yourself.
