What can cause Insomnia?

Treatment for transient and short-term insomnia

Transient and short-term insomnia: This type of insomnia may not require treatment since these episodes may last few only a few days at a time. For some people who experience daytime sleepiness and impaired performance may benefit from the use of short-acting sleeping pills, which may improve sleep and next-day alertness. There are always potential side effects associated with the use of any type of sleeping aid. Please consult your physician prior to use.

Treatment for chronic insomnia consists of:

Consulting your physician for diagnosing and treating any medical or psychological problems.
Identifying any personal behaviors that contribute to your insomnia.

Any patient taking sleeping pills should be under the supervision of a physician. Your physician needs to evaluate the effectiveness of any sleep aids and to minimize any side effects associated with the sleep aids.

Behavioral techniques to improve sleep, such as relaxation therapy, sleep restriction therapy, reconditioning, and/or bright light therapy may try.

Relaxation Therapy. There are specific and effective techniques that can be used to reduce or eliminate anxiety and body tension so that your body can relax and you may obtain restful sleep.

Sleep Restriction. People suffering from insomnia may spend too much time in bed trying to fall asleep. A sleep restriction program may benefit the insomniac by trying only a few hours of sleep during the night then gradually increasing your time period in bed until a more normal night’s sleep is achieved.

Reconditioning. Reconditioning is a treatment that reprograms you to associate the bed and bedtime with sleep. For example, not using their beds for any other activities other than for sleep and sex. i.e. no eating, reading, watching t.v., or working in your bed. With this, the person is advised to go to bed only when they are sleepy. If you are unable to fall asleep, you should get up and stay up until you are feeling sleepy, and then return to bed. When trying this process, you should avoid taking naps and go to bed and wake up at the same time each day. With this exercise, your body will be conditioned to associate the bed and bedtime with sleep.

Bright Light. Try resetting your internal clock by waking up the same time every morning and allowing as much bright light into your bedroom in the morning as possible. If you are having trouble staying awake in the evening, make it as bright in your home as possible.

Sleep State Misperception: Sleep state misperception is where a person will sleep most of the night but believe that they did not sleep at all.
