Insomnia : Insomnia: The perception or complaint of inadequate or poor-quality sleep because of one or more of the following: difficulty falling asleep; waking up frequently during the night with
difficulty returning to sleep; waking up too early in the morning; or unrefreshing sleep. Insomnia is not defined by the number of hours of sleep a person gets or how long it takes to fall asleep.
Individuals vary normally in their need for, and their satisfaction with, sleep. Insomnia may cause problems during the day, such as tiredness, a lack of energy, difficulty concentrating, and
irritability.
Types of Insomnia: Insomnia can be classified as transient (short term), intermittent (on and off), and chronic (constant). Insomnia lasting from a single night to a few weeks is referred
to as transient. If episodes of transient insomnia occur from time to time, the insomnia is said to be intermittent. Insomnia is considered to be chronic if it occurs on most nights and lasts a month
or more.
Causes of Insomnia: Certain conditions seem to make individuals more likely to experience insomnia. Examples of these conditions include: advanced age (insomnia occurs more frequently in
those over age 60); female gender; and a history of anxiety , a medical problem, or the use of certain medications) occur along with the above conditions, insomnia is more likely.
There are many causes of insomnia. Transient and intermittent insomnia generally occur in people who are temporarily experiencing one or more of the following: stress, environmental noise, extreme
temperatures, a change in the surrounding environment, sleep/wake schedule problems such as those due to side effects .
Chronic insomnia is more complex and often results from a combination of factors, including underlying physical or mental disorders. One of the most common causes of chronic insomnia is depression.
Other underlying causes include caffeine , alcohol, or other substances; disrupted sleep/wake cycles as may occur with shift work or other nighttime activity schedules; and chronic stress.
Certain Behaviors: Behaviors that perpetuate insomnia in some people include: expecting to have difficulty sleeping and worrying about it, ingesting excessive amounts of caffeine, drinking
alcohol or smoking cigarettes before bedtime, excessive napping in the afternoon or evening, and irregular or continually disrupted sleep/wake schedules. These behaviors may prolong existing insomnia,
and they can also be responsible for causing the sleeping problem in the first place. Stopping these behaviors may eliminate the insomnia altogether.
Who Has Insomnia? Insomnia is found in males and females of all age groups, although it seems to be more common in females (especially after menopause ) and in the elderly. The ability to
sleep, rather than the need for sleep, appears to decrease with advancing age.
Diagnosis of Insomnia: Patients with insomnia are evaluated with the help of a sleep apnea or narcolepsy.
Treatment of Transient and Intermittent Insomnia: These may not require treatment since, by definition, the episodes of insomnia only last a few days at a time. For example, if insomnia is
due to a temporary change in the sleep/wake schedule, as with jet lag, the person's biological clock will often get back to normal on its own. However, for some people who experience daytime sleepiness
and impaired performance as a result of transient insomnia, the use of short-acting sleeping pills may improve sleep and next-day alertness. As with all drugs, there are potential side effects. The use
of over-the-counter sleep medicines is not usually recommended for the treatment of insomnia.
Treatment of Chronic Insomnia: The treatment of chronic insomnia consists of: - First, diagnosing and treating underlying medical or psychological problems.
- Identifying behaviors
that may worsen insomnia and stopping (or reducing) them.
- Possibly using sleeping pills, although the long-term use of sleeping pills for chronic insomnia is controversial. A patient taking any
sleeping pill should be under the supervision of a physician to closely evaluate effectiveness and minimize side effects. In general, these drugs are prescribed at the lowest dose and for the shortest
duration needed to relieve the sleep-related symptoms. For some of these medicines, the dose must be gradually lowered as the medicine is discontinued because, if stopped abruptly, it can cause
insomnia to occur again for a night or two.
- Trying behavioral techniques to improve sleep, such as relaxation therapy , sleep restriction therapy, and reconditioning.
Relaxation Therapy: There are specific and effective techniques that can reduce or eliminate anxiety and body stop "racing," the muscles can relax, and restful sleep can occur. It
usually takes much practice to learn these techniques and to achieve effective relaxation.
Sleep Restriction: Some people suffering from insomnia spend too much time in bed unsuccessfully trying to sleep. They may benefit from a sleep restriction program that at first allows only a
few hours of sleep during the night. Gradually the time is increased until a more normal night's sleep is achieved.
Reconditioning: Another treatment that may help some people with insomnia is to recondition them to associate the bed and bedtime with sleep. For most people, this means not using their beds
for any activities other than sleep and sex. As part of the reconditioning process, the person is usually advised to go to bed only when sleepy. If unable to fall asleep, the person is told to get up,
stay up until sleepy, and then return to bed. Throughout this process, the person should avoid naps and wake up and go to bed at the same time each day. Eventually the person's body will be conditioned
to associate the bed and bedtime with sleep.
