Some nights it seems you never drop off at all. There are three medically recorded types of insomnia . Transient insomnia lasts only a night or two, or, at most, a week. It is usually caused by some outside influence like excitement or worry. Worry over other health problems, business or relationships can bring on a bout of short term insomnia.
Chronic insomnia is a serious problem.
These three types may often overlap. Although anyone can become a victim of insomnia, some people are more susceptible than others. The elderly , for instance, are often afflicted, perhaps because of physical and mental problems or because some medications promote sleeplessness. Those who suffer from chronic depression also sometimes suffer from insomnia because of their poor state of mind brought on by depression and worry. Women are more often victims than men.
