NOTE: In catalogue, place next to SAD Light with SAD info box that applies to both products The most effective light therapy in the world Valkee is a little like a Walkman or an i-Pod with light coming out of the earphones instead of sound. It beams a specific wavelength of light through the ear canal directly onto the most photo-sensitive part of the brain to give you the natural mood-lifting effects of being in the sun. Bizarre as it sounds, scientific studies have found that just 8 minutes using this CE Class II (a) medical device is even more effective than two hours of the best conventional SAD light. In trials at the University of Oulu, one of Finland’s largest universities, 92.3% of participants said that Valkee gave them more energy, reduced mood swings & anxiety, & enhanced sleep & mental performance. The research programme also showed dramatic results for other sleep problems, especially jet lag. Trials are now ongoing in other areas, & early results for migraine are particularly promising.
