Insomnia is more than just simply not being able to fall asleep at night. Waking frequently during the night, or waking extremely early are also common in insomnia sufferers. While most of us have dealt with insomnia at some time or another, it is estimated that over 30% of the general population are true insomniacs. That is, they have recurring difficulty getting tosleep, or staying there.
There are two general types of insomnia. Secondary insomnia is usually brought on by a temporary situation, such as stress, illness, noise, or medication. This type of insomnia often goes away after a week or less, without any form of medical treatment. Making changes in diet, such as avoiding caffeine and not eating late in the day, can help relieve secondary insomnia.
