SAD, Winter Blues and Light Therapy in Stockholm

Umea Energy has installed light therapy panels in 30 bus stops in a town north of Stockholm that gets only about five hours of daylight during its darkest winter months. The back-lit advertisements that once hung in the bus stop shelters will be replaced with these light panels for several weeks.

These panels are proven to help with Seasonal Affective Disorder (SAD), which is a result of lack of sunlight, causing one to feel tired and depressed from overproduction of the hormone melatonin.  Commuters are encouraged to stand in front of the panels with their eyes open—for a full 30 minutes for the maximum effect.
