Seasonal affective disorder (SAD) is a type of depression that occurs during certain seasons, usually during the winter months. A common treatment for SAD is light therapy, where patients are exposed to bright lights for a few hours each day. If exposure to bright lights helps alleviate the depression, it may suggest that the depression is due to SAD. Therefore, determining if exposure to bright lights helps alleviate the depression is one way to determine if the depression is due to seasonal affective disorder or to some other form of depression.
