Can't Sleep? What to know about insomnia.. :D

Insomnia, which is Latin for "no sleep," is the inability to fall asleep or remain asleep. Insomnia is also used to describe the condition of waking up not feeling restored or refreshed. According to Dr. Mark Mahowald, Professor of Neurology at the University of Minnesota Medical School and Director of the Minnesota Regional Sleep Disorders Center at Hennepin County Medical Center, insomnia refers to the inability to get the amount of sleep you as an individual need to wake up feeling rested.

Insomnia can be a disorder in its own right, but often it is a symptom of some other disease or condition. Half of all those who have experienced insomnia blame the problem on stress and worry. In the case of stress-induced insomnia, the degree to which sleep is disturbed depends on the severity and duration of the stressful situation. Sometimes this may be a disturbing occurrence like loss of a loved one, loss of a job, marital or relationship discord or a tragic occurrence. Anticipation of such things as weddings, vacations, or holidays can also disturb sleep and make it difficult to fall asleep or remain asleep. Insomnia can also occur with jet lag, shift work and other major schedule changes.

If you have difficulty sleeping, it is essential to determine whether an underlying disease or condition is causing the problem. Sometimes insomnia is caused by pain, digestive problems or a sleep disorder. Insomnia may also signal depression or anxiety. Often times, insomnia exacerbates the underlying condition by leaving the patient fatigued and less able to cope and think clearly. For insomnia related to a medical condition or pain, ask your doctor about nighttime pain aids.

If your sleep trouble is confined to difficulty falling asleep, the time you are choosing to go to sleep may not be synchronized with your biological clock. The biological processes that initiate and maintain sleep in humans are active throughout the night. Opposing this sleep tendency, however, is the alerting action of the biological clock that is active throughout the day. When the biological clock is active at your scheduled bedtime, you will have sleep-onset insomnia.

The prevalence of insomnia is higher among older people and women. Women suffer loss of sleep in connection with menstruation, pregnancy, and menopause. Rates of insomnia increase as a function of age but most often the sleep disturbance is attributable to some other medical condition.

Some medications can lead to insomnia, including those taken for:

• colds and allergies
• high blood pressure
• heart disease
• thyroid disease
• birth control
• asthma
• pain medications
• depression (especially SSRI antidepressants)

 Some common sleep disorders such as restless legs syndrome and sleep apnea can also lead to insomnia.

Sleep is as essential as diet and exercise. Inadequate sleep can result in fatigue, depression, concentration problems, illness and injury.

• Make sure your bedroom is quiet, dark, and cool. Noise, light, and heat can interfere with sleep. Try using a sound machine or earplugs to mask outside noise, an open window or fan to keep the room cool, and blackout curtains or an eye mask to block out light.
• Stick to a regular sleep schedule. Support your biological clock by going to bed and getting up at the same time every day, including weekends. Get up at your usual time in the morning even if you’re tired. This will help you get back in a regular sleep rhythm.
• Avoid naps. Napping during the day can make it more difficult to sleep at night. If you feel like you have to take a nap, limit it to 30 minutes before 3 p.m.
• Avoid stimulating activity and stressful situations before bedtime. This includes vigorous exercise; big discussions or arguments; and TV, computer, or video game use. Turn off all electronics at least an hour before bed.
• Limit caffeine, alcohol, and nicotine. Stop drinking caffeinated beverages at least 8 hours before bed. Avoid drinking in the evening. While alcohol can make you feel sleepy, it interferes with the quality of your sleep. Quit smoking or avoid it at night, as nicotine is a stimulant.

• Use the bedroom only for sleeping. Don’t work, read, watch TV, or use your computer in bed or the bedroom. The goal is to associate the bedroom with sleep alone, so that your brain and body get a strong signal that it’s time to nod off when you get in bed.
• Get out of bed when you can’t sleep. Don’t try to force yourself to sleep. Tossing and turning only amps up the anxiety. Get up, leave the bedroom, and do something relaxing, such as reading, drinking a warm cup of caffeine-free tea, taking a bath, or listening to soothing music. When you’re sleepy, go back to bed.
• Move bedroom clocks out of view. Anxiously watching the minutes tick by when you can’t sleep—knowing that you’re going to be exhausted when the alarm goes off—is a surefire recipe for insomnia. You can use an alarm, but make sure you can’t see the time when you’re in bed.
