How does the "SAD Light" work? In autumn and winter, the seasons with the least sunlight because of shorter days, the lack of sunlight, and a problem with certain brain chemicals stop the hypothalamus from working properly. The lack of light is thought to affect the production of the hormone melatonin (which makes you sleepy). "SAD Light" uses bright lights to simulate the sunlight during the darker autumn and winter, whilst eliminating the dangerous UV rays contained in sunlight. The additional light helps your brain to reduce the production of the hormone melatonin, adjust the levels of melatonin that can help the symptoms of SAD or winter depression.
