The Valkee (http://valkee.com) bright light headset channels bright light direct to the human brain via the ear canal to prevent and cure depression, mood swings and circadian-rhythm disorders such as jetlag. In clinical trials, 9 of 10 patients suffering from severe seasonal affective disorder - also known as winter blues - experienced total relief from their symptoms in 4 weeks with a daily 8-12 minute dose.
