HOW TO PREVENT

Establish a lifestyle that fosters healthy sleep patterns.

What To Expect

DIAGNOSTIC MEASURES--

• Medical history and exam by a doctor.
• Laboratory thyroid studies, EEG (See Glossary).
• Tests in a sleep-study laboratory (sometimes).

APPROPRIATE HEALTH CARE

• Self-care after diagnosis.
• Doctor's treatment; psychotherapy or counseling, if the cause is psychological.

POSSIBLE COMPLICATIONS

• Transient insomnia becomes chronic.
• Increased daytime sleepiness that can affect all aspects of your life.

PROBABLE OUTCOME--Most persons can establish good sleep patterns if the underlying cause of insomnia is treated or eliminated.

How To Treat

GENERAL MEASURES--

• Seek ways to minimize stress. Learn and practice relaxation techniques.
• Don't use stimulants close to bedtime.
• Treat any underlying or medical cause.
• Relax in a warm bath before bedtime.
• Don't turn your bedroom into an office or a den. Create a comfortable sleep setting.
• Turn off your mind. Focus on peaceful and relaxing thoughts. Play soft music or relaxation tapes. Set a rigid sleep schedule.
• Use mechanical aids such as ear plugs, eye shades or electric blanket.

MEDICATION--Your doctor may prescribe sleep-inducing drugs for a short time if:

• Temporary insomnia is interfering with your daily activities.
• You have a medical disorder that regularly disturbs sleep.
• You need to establish regular sleep patterns. Long-term use of sleep inducers may be counter-productive or addictive.

ACTIVITY-- Exercise regularly to create healthy fatigue, but not within 2 hours of going to bed.

DIET--

• No special diet, but don't eat within 3 hours of bedtime if indigestion has previously disturbed your sleep. Drinking warm milk before bedtime helps some. Limit caffeine consumption.

Call Your Doctor If

• You have insomnia and self-help methods are ineffective.
• New, unexplained symptoms develop.
