If you have a tendancy to pack on a few extra pounds during the winter months, you might be able to blame lack of sunlight. University of Alberta researchers have found that fat cells that lie just beneath out skin shrink when exposed to the blue light emitted by the sun. Senior study author, Peter Light, explains, "the insufficient sunlight exposure we get eight months of the year living in a northern climate may be promoting fat storage and contribute to the typical weight gain some of us have over winter." Still, he cautions that way more research is needed on the topic so you shouldn't expose yourself to sunlight in an attempt to lose weight.
