Light Device Helps Beat Winter Blues, University of Oulu Study

People who suffer from Seasonal Affective Disorder (SAD) — a condition that comes with a shortage of daylight hours — may have a new weapon to fight off those winter blues, according to a study by Finnish researchers. These researchers explain that the human brain is as sensitive to light as the eyes, making it possible to treat SAD with a new headset — much like headphones — that beams light, rather than music, into the ears.
