Insomnia means difficulty sleeping. By not sleeping normally, the body is saying that something is not right. Any number of factors may be the cause such as stress, illness, overweight, depression, anxiety, or drugs. Jet lag, arguing, or lack of exercise may also cause it. Insomnia is not a side effect of aging. It is likely to be a symptom for physical or emotional problems. Symptoms of insomnia:
* Trouble falling asleep (taking longer than 45 minutes).
* Cannot stay asleep during the night.
* Waking up several times in the night.
* Problems with waking up earlier than usual.
* Increased daytime fatigue and agitation.
* Trouble coping.
* A combination of any of the above symptoms.

Types of insomnia:
* Short-term insomnia may last until the problem is resolved. It is often due to worry over a stressful situation such as divorce, noise, pain, stress, work stress, or grief.
* Long-term insomnia may persist for months or years. Causes may be factors like general anxiety, chronic pain, depression, other physical disorders, or drugs.

Restful sleep restores energy and allows the body to renew itself. It keeps the body's immune system strong. Restful sleep is important to well-being. Try these tips to improve sleep and avoid insomnia:
* Lose weight if you're overweight.
* Don't watch TV, or do work while in bed.
* Eat lightly if it is late at night.
* Do not drink alcohol within 6 hours of bedtime.
* Avoid caffeine after the morning hours.
* Avoid daytime naps.
* Exercise 30 to 60 minutes every day.
* Try a hot bath and a cup of warm milk before bed.

If these tips do not work, you may have a medical condition that needs to be evaluated. Never take over-the-counter sleeping aids, including melatonin, without seeking medical advice first. Sleeping pills of any kind should be a last resort.
