The term "Löyly" comes from the Finnish word for the steam and heat that is released when water is thrown onto hot stones, creating an intense humidity that engulfs occupants in a cocoon of warmth, cleansing the skin and opening pores, enhancing the detoxifying effects of the sauna.
In traditional Finnish culture, löyly is the very spirit of the sauna - the essence that makes it more than just a hot room, and a sensory and spiritual experience for the soul.
