The FDA recently approved Wellbutrin XL for seasonal depressive episodes (often called Seasonal Affective Disorder or S.A.D.). Fortunately for folks who have this condition, some recent research has also shown light-therapy to be as effective (if not more so) than medication. The belief is that being outdoors and in sunlight contributes to optimal human functioning. Since people spend more time indoors (especially during the winter in some parts of the world), the loss of light contributes to depressed mood and lethargy. According to the study, the standard light-therapy dose is 10,000 lux for 30 minutes as soon as a person wakes up in the morning (work with a professional to determine the best option for you). This can help improve mood with very few side effects (skin irritation, headaches, eye strain, etc) and can even work faster than medication. Working with a psychologist to help in adjusting to seasonal change and to create a prevention strategy could also be a helpful part of the equation.
