Genetics may be to Blame for Some Insomnia

Insomnia is a widespread problem experienced by many people; it is estimated that 20 percent of Americans and 50 percent of military veterans suffer from problems with sleep. New research has indicated that several genes may have a role in the development of sleep disorders. The scientists have also shown that there is a genetic link connecting psychiatric disorders like depression, insomnia, and poor health conditions like type 2 diabetes. Chronic insomnia can have a devastating impact on health; lack of sleep often has a domino effect. Long-term health problems can develop along with insomnia, including heart problems and mental illness. Many veterans know all to well that post-traumatic stress disorder (PTSD) and insomnia are also closely connected.
