2. What is SAD? • Seasonal Affective Disorder (SAD) is a type of winter depression that affects an estimated half a million people every year. It is believed to be caused by an imbalance of chemicals in the brain. • In the winter there is a decrease in the amount of natural light that reaches us. This is due partly to less daylight hours and partly to changing weather patterns. • This lack of sunlight causes a reduction in serotonin production and an increase in the level of melatonin. This produces the symptoms associated with SAD.
