Finland has been ranked first in global happiness levels for six years in a row. Löyly (the closest attempt to transcribe it into Hebrew would be olu - but the letter Y should be pronounced like the German letter ü, meaning a sound that is between ou and ei) is basically the Finnish word for steam.
In Finnish culture it is associated with the sauna experience, with the warm and fragrant air that surrounds the body and seemingly penetrates the soul.
