Often we may feel sluggish and low in energy during inclement weather; however, Seasonal Affective Disorder (SAD) is more than feeling the occasional winter or rainy day blues. Depression related to seasonal change can be severe and affects up to 6% of the general population. Symptoms of SAD usually manifest in the fall and continue throughout the winter months; although, some people experience symptoms beginning in the spring or summer months. In either situation, symptoms may begin mildly and become increasingly more severe as the season progresses.
Because Seasonal Affective Disorder is a subtype of Major Depressive Disorder (MDD), people often suffer with the same symptoms as in depression.
