Durham, N.C. -- The winter months are a time when many people find themselves feeling a little depressed. Psychologist Ruth Quillan with the Duke University Center for Living says this is a fairly typical reaction to the lack of sunlight -- short days and long nights. But for some people, that depression comes back every year and continues for weeks or even months. These folks may be suffering from what is called "Seasonal Affective Disorder." Quillan says if you suspect you have S-A-D, there is something you can try.

"There's clear evidence, both clinically and empirically, that using artificial light -- particularly a light that mimics the sun -- can help. They actually sell light boxes that people can purchase to spend 20 to 30 minutes in front of in the early morning. They help people's moods dramatically."

Quillan says feeling "blue" every once in a while on a gray day is common, but having it happen consistently and for long periods of time is not.
