Insomnia is most often caused by sleep disorders, but other causes include fear, stress, anxiety, medications, herbs and caffeine. An overactive mind or physical pain may also be a cause... According to the U.S. Department of Health and Human Services, approximately 60 million Americans each year suffer from insomnia. Insomnia tends to increase with age and affects about 40 percent of women and 30 percent of men."
