löylys
Löyly is a Finnish word that refers to the steam that rises from a hot sauna stove when water is thrown onto the heated stones. It is a fundamental element of the sauna experience, contributing to the characteristic heat and humidity. The act of throwing water onto the stones to create löyly is called "löylyn heittäminen" or "löylyn ottaminen." The temperature and humidity generated by the löyly can be adjusted by varying the amount of water thrown and the frequency. Different types of water, such as fresh or salt water, can also influence the sensation and aroma of the löyly. In Finnish culture, löyly is often described as having a purifying and therapeutic effect, both physically and mentally. It is an integral part of social gatherings and a symbol of well-being and relaxation. The intensity and quality of the löyly are highly valued by sauna enthusiasts, and the creation of good löyly is considered an art form by some. The term is uniquely Finnish and does not have a direct English translation, though "steam" or "sauna steam" are often used as approximations.
