The past ten years have brought increased awareness of a condition known as Seasonal Affective Disorder; also know as SAD or Winter Depression. Its symptoms are similar to depression. The main difference being that SAD occurs mainly during the winter. For many who suffer depression year round their symptoms get worse during the winter.

Although much is still unknown it is generally believed that people who suffer from SAD are sensitive to the decline of light during the darker season. Our exposure to light effects our hormone levels. Serotonin, a hormone associated with mood elevation, increases when you’re exposed to bright light. Melatonin, the sleep hormone, decreases when we are exposed to light and increases with darkness. Increased melatonin tells our bodies it’s time to rest. This may explain why we are more tired in the winter.Many studies show that people suffering from seasonal affective disorder feel better after exposure to bright light.
