About Insomnia

Insomnia is a common and distressing problem and includes difficulty in falling asleep, getting back to sleep or waking too early.  Most adults have experienced insomnia at one time or another in their lives. An estimated 30 to 50% of the general population are affected by insomnia, and 10% have chronic insomnia.  In a recent Australian study it was found that almost 20% of the people were chronically sleep restricted and 12% were chronically sleepy.  The author of the study states that “this prevalence of chronic sleep restriction is likely to have a significant influence on public health in Australia.”1
