löyhii
Löyhii is a Finnish term that broadly refers to the steam in a Finnish sauna. It is considered a crucial element of the sauna experience, contributing to the characteristic heat and humidity. The generation of löyhii is typically achieved by throwing water onto the hot stones of the sauna stove, known as a kiuas. The amount and timing of the water thrown can influence the intensity of the löyhii, allowing individuals to customize their sauna experience.
The sensation of löyhii is described as a wave of heat and moisture that envelops the body.
