The design concept of the Nordic Light Hotel features a look that changes with the seasons. Light, being an easily adjustable medium, therefore takes on a central role here. Light scenes with slow and soft transitions interpret the diffuse light of these latitudes, while brilliant effects and projections are evocative of phenomenon such as the Northern Lights. The hotel rounds off its health and relaxation facilities with special photo-therapeutic treatments: insipid infrared light is held to increase blood circulation and make the skin soft and smooth. To combat winter depression, guests can lie for half an hour under a mobile 10,000-lux light system, which promotes melatonin production.
