Insomnia is characterized by difficulty falling asleep or difficulty staying asleep. Intermittent insomnia affects about two thirds of Americans and about nine percent of Americans will have it more than twice a week.
Insomnia may also be a symptom of a more serious sleep disorder such as Obstructive Sleep Apnea. This is frequently seen when someone has multiple awakenings throughout the night.
Avoiding naps, going to bed at the same time each night and waking up at the same time each morning may help. It also helpful to abstain from alcohol, tobacco, and caffeine.
Cognitive Behavioral Therapy is a set of learned behaviors that may aid in falling back to sleep. These are classically learned from a psychologist but may also be obtained online.
In some cases medications can be prescribed by your physician that may also contribute to your treatment.
