What is seasonal depression?
As the seasons change and the days get shorter, some people develop symptoms of depression, known as Seasonal Affective Disorder (SAD). SAD is related to seasonal changes in the amount of daylight that can bring about feelings of hopelessness and sadness, a drop in energy level, fatigue, irritability, difficulty concentrating, and avoidance of social situations, changes in appetite, decreased physical activity, and sleeping for long periods of time. Symptoms of SAD tend to reoccur at about the same time every year. Four to six of every 100 people are diagnosed with SAD. Some people experience symptoms severe enough to affect their quality of life, and 6 percent require hospitalization. SAD appears to be more common in Northern states.

Is treatment available for seasonal depression?
The treatment of choice is Bright Light Therapy (BLT), which uses a particular type of light called “white light” to match the radiation one gets from natural sunlight shortly after sunrise or before sunset. This treatment is often taken at home, and exposure ranges from 15 minutes to 3 hours, depending upon the brightness of the light source. Some people need a combination of Bright Light Therapy, psychotherapy, and medication. Persons with SAD also may benefit from using self-care tips, such as monitoring one’s energy level, taking advantage of available sunlight, staying physically active, and maintaining a positive attitude when the winter season approaches. If you think you may be experiencing symptoms of SAD, consult with a health care provider or mental health professional.
