Introduction

Nearly everyone has occasional sleepless nights, perhaps due to stress, heartburn, or drinking too much caffeine or alcohol. Chronic insomnia is defined when you have problems falling asleep, maintaining sleep, or experience nonrestorative sleep that occurs on a regular or frequent basis, often for no apparent reason.

How much sleep is enough varies from person to person. Although 7 1/2 hours of sleep is about average, some people do well on four to five hours of sleep. Other people need nine to 10 hours of sleep each night.

Insomnia can affect not only your energy level and mood, but also your health as well because sleep helps bolster your immune system. Fatigue, at any age, leads to diminished mental alertness and concentration. Lack of sleep caused by insomnia is linked to accidents both on the road and on the job.

Insomnia is a common problem that may be temporary or chronic. As many as one in 10 Americans have chronic insomnia, and at least one in four has difficulty sleeping sometimes. But that doesn't mean you have to just put up with sleepless nights. Some simple changes in your daily routine and habits may result in better sleep.
