Light therapy has been around for quite some time. It helps to fight against SAD (Seasonal Affective Disorder), sleep disorders and skin problems. It’s also known as phototherapy and heliotherapy.
In 2012, one energy company installed phototherapy lights in bus stops in the northern Swedish town Umea. The lights were placed underneath the bus stops in order to help people fight off the winter blues they were experiencing during the cold season. Since light hours in Sweden are reduced to just 4 to 6 hours daily during the winter months, Swedes tend to become depressed by the lack of natural light. The energy company’s light therapy uses renewable sources of artificial light such as hydropower, wind and even solar energy.
The project seems useful, although some Swedes have been complaining about the lights. According to them, they are too bright and even dazzling, which makes it difficult for many drivers to pass them when it’s dark outside.
