Seasonal Affective Disorder (SAD) is a depressive illness caused by shortened day light hours and a lack of sunlight. Affecting a growing number of people in the UK, at any age, a number of treatments are available to help combat SAD but the least invasive and one of the most effective is light therapy through the use of SAD lamps. It is shown SAD lamps improve the symptoms of SAD by encouraging the brain to reduce the production of melatonin (a hormone that makes you sleepy) and increase the production of the mood-affecting hormone serotonin. For effective treatment, the SAD lamp has to be 10,000 lux (one lux is equivalent to the light of one candle). The TL 50 is a classified medical grade II product, offering 10,000 lux, as are all Beurer SAD lamps. Thanks to its compact size due to LED technology, the TL 50 is easy to place in your home or place of work without being intrusive. Its impressive rounded profile will illuminate your space with even, flicker-free light, while lending a contemporary touch to your interior styling.
