Fun fact:
Löyly is a finnish word meaning the act of throwing water on the hot stones on the sauna's stove to create a wave of hot steam in the sauna (ex. "throw some löyly"). Suu is throwing löyly in the middle panel of page 4.
Some non-finnish saunas don't have a stove with rocks, instead the sauna is just a hot room. The word löyly doesn't seem to translate to other languages, I would love to know if the original text also called it löyly.
