What is insomnia?

Insomnia is difficulty falling asleep, staying asleep, or getting sufficient sleep. This lack of sleep affects your ability to function during the day, and can cause distress. An estimated 30% - 60% of adults are affected by insomnia, with more women being affected than men. Its incidence tends to increase with age.

Insomnia is not defined by getting a specific number of hours of sleep, because people vary in their sleep needs. Adults who get between 6 and 7 hours of sleep per day tend to be the healthiest and longest-lived. However, regularity of sleep is more important than the amount, as discussed in Grow Youthful.
