For those of you with winter-SAD, it is not simply a winter condition -- it is a light-deficiency condition. Any time the light levels fall too low -- even in midsummer -- you are at risk for symptoms.
The snow, the ice and the chilled wind keep us inside more than we might like. Some of us, however, are affected more than others. Folks who suffer from Seasonal Affective Disorder display symptoms of extreme SAD-ness: boredom, depression, exhaustion and burn out.
