Insomnia

Insomnia is a condition where either falling or staying asleep is difficult, leading to problems with daytime functioning. Insomnia is not the same thing as sleep deprivation, which is caused by a lack of opportunity to sleep.

Insomnia is very common and affects people of all ages, although it is more common in adults. Women are also more likely to suffer from sleeplessness than men. It is reported that one-third to one-half of people in the United States will experience insomnia at least once, and that 10 percent suffer from chronic, or repeated, insomnia.

There are three types insomnia, based on the length of time a person experiences it for.

  • Transient: Lasts one week or less
  • Short-term: Lasts 1-3 weeks
  • Long-term or chronic: Lasts more than three weeks
