Some studies suggest that one in three Americans suffers from chronic insomnia. Most emotional disorders can cause sleep disturbance. Chronic insomnia can be a symptom of depression, anxiety, dementia, or panic disorder. A number of medical problems can also cause insomnia. Cardiovascular disease, heartburn, asthma, and thyroid disease are among the most common.
Drugs are also common causes of insomnia.
Stimulants like caffeine can disturb sleep. Chronic use of sedatives can also create worsening insomnia. Last but not least, substance abuse can also cause sleep problems. If you are experiencing a problem with your sleep, a visit to your primary care doctor's office is highly recommended. Always consult your own doctor about any opinions or recommendations with respect to your symptoms or medical condition.
