The Valkee bright light headset makes the treatment of SAD (or general glumness) as effortless as popping in a pair of ear buds. Traditional light therapy treatments typically require the subject to sit in front of a light therapy box, which bathes them in simulated sunlight. Valkee, however, directs this bright light through the ear canal to the light-sensitive portions of the brain, via light-emitting ear buds connected to a portable headset. Six to twelve minutes of daily, on-the-go use is purported to increase energy and prevent moodiness, with effects rivaling a 30-minute to two-hour session in front of a traditional light box.
