The “winter blues” might be more than just blues, it could be seasonal depression, which is also known as seasonal affective disorder, or SAD.

According to Mental Health America, in a given year, about 5% of the U.S. population experiences seasonal depression, and the prevalence of seasonal depression up to 10% of the population, depending on geographic region.

Seasonal affective disorder is a type of depression that is related to changes in seasons. Symptoms of the seasonal depression tend to start and end at roughly the same time every year. In most cases, symptoms appear during the late fall or early winter months and stop during the spring or summer months.
