What Is Seasonal Affective Disorder (SAD)?

This particular article discusses Seasonal Affective Disorder (SAD) as a predictable form of depression triggered by the reduction of sunlight during the autumn and winter months. This environmental shift disrupts the body's internal clock and lowers serotonin levels, leading to physical symptoms like oversleeping, carbohydrate cravings, and persistent fatigue. The article emphasizes that SAD is a biological condition rather than a personal weakness and highlights effective treatment options—including light therapy, lifestyle adjustments, and EMDR—to help individuals recalibrate their nervous systems and maintain emotional balance throughout the year.
