How does the "Daylight" 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 stops the hypothalamus working properly. The lack of light is thought to
affect the production of the hormone melatonin (that makes you sleepy). "Daylight" uses very 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 to production of hormone melatonin, adjust the
levels of melatonin that can help the symptoms of SAD or winter depression.
