Sleeplessness is something we've likely all experienced at some point in our lives. Whether it was brought on because of stress, caffeine, or a genuine sleep disorder, those hours of tossing and turning, when your mind feels wired and your eyes refuse to get heavy, are so uncomfortable they're hard to forget.

What is Insomnia?

According to the National Heart, Lung and Blood Institute, there are two varieties of insomnia: secondary and primary. In secondary insomnia, the difficulty sleeping isn't the condition, but is rather a side effect of another condition, such as anxiety, depression, pain, medicine, tobacco, or another sleep disorder. Primary insomnia, where the sleep disruption isn't caused by an outside factor, is far less prevalent, and tends to persist for at least a month. The different types of insomnia and their effects on different populations are discussed further at the Web sites below.
