Insomnia Insomnia is a condition where people have difficulty in sleeping. It varies from restless or disturbed sleep to a reduction in the usual time spent sleeping and, in the extreme, may involve complete wakefulness. There can be many different causes for insomnia. Many elderly people typically sleep lightly and fitfully.
Sleeplessness is also common during pregnancy, especially in the later weeks.
In most cases, however, the core problem is emotional. There are a number of ways to help yourself fall asleep more easily. It is often possible to break the cycle of insomnia by deliberately staying awake for an entire night.
