Seasonal affective disorder (SAD) is a condition that can occur among individuals who have normal mental health through most of the year. These individuals tend to experience and exhibit depressive symptoms at the same time annually. This is most commonly seen during the winter season.
Seasonal affective disorder has been thought to be due to the body’s response to the reduction of sunlight. Treatment includes medication, light therapy, cognitive behavioral therapy, melatonin supplementation, and ionized air administration.
In the United States, seasonal affective disorder ranges from 1.4 percent in Florida to 9.9 percent in Alaska.
