Light makes the melatonin dissapate. It's secreted in the dark, and makes a person sleepy, even sluggish or worse. In "nature", the light of dawn would dissapate the night's melatonin. Some say that even a cloudy day has a lot more light than a room lit with an ordinary bulb. You can imagine that during the winter, especially when the weather is cloudy, a person doesn't get enought light to feel good. The light box mimics an early, bright dawn and in a sense tricks the brain into thinking it's a bright, long, summery day. Not sure about why you would get a headache in the sun- maybe it's got to do with your own chemistry? Now I'm curious, Phillippa. Do you experience a winter slump such as SAD?
> Monte it reduces melatonin why is that? And why headaches out in the sun without sunglasses. Love Phillipa
