In spite of all the over-dramatization cinema and literature have given to the idea of insomnia, many people simply want to know, “Do I have insomnia myself?” Many people think that insomnia is a sort of terrible sickness or disease, deriving these thoughts from the heavy-handed influence of art. Actually, insomnia is merely a symptom, or a sign, of disease, and is not a sickness or disease itself.The simplest way to describe insomnia is as follows: insomnia is when you have difficulty falling asleep or remaining asleep. Of course, insomnia can vary greatly in severity, ranging from being a minor nuisance to preventing sleep altogether; this is important to keep in mind when deciding whether or not you would like to seek medical attention. For instance, if it generally takes you an hour of lying in bed each night before you can fall asleep, but if you thereafter find yourself sleeping through the night, it might not be worth seeking medical treatment. It might be something as simple as stress or uptightness that is causing this delay of sleep, or “light insomnia.” You will be rid of this insomnia as soon as you solve the stress itself. On the other hand, if you are dealing with a situation where you are extremely tired and sleep-deprived and are still unable to fall asleep or sleep through the night, you might be dealing with a more severe case of insomnia. Consider seeking medical assistance if you are experiencing such a situation, where you are unable to sleep through the night or to fall asleep at all, even when your body is immensely tired. Insomnia can be a symptom of any number of disorders, many of them dealing with mind- or muscle-related issues. Another common cause of insomnia is medication. If you have insomnia, it can be kept at bay with any number of prescribed drugs; or, you can remove the insomnia entirely by curing the disorder that is causing the insomnia. By seeking medical assistance when you have a severe case of insomnia, you can find out what is causing the insomnia, and you can take measures to solve this problem.
