Americans suffer from a chronic sleep disorder, and an additional 20 to 30,000,000 are affected by minute sleep related problems. However an overwhelming majority of sleep disorders remain undiagnosed and untreated. Sleep deprivation and sleep disorders are estimated to cost americans over million annually in lost productivity, medical expense, sickleave, and property and environmental problems. And estimated 100,000 reported crashes are caused by drowsy drivers each year. These crashes result in more than 1500 fatalities and 71,000 injuries.
