Finland

In Finland, it is estimated that there are 3.5 million saunas. They even exist in fast food restaurants. And no steam is left unexplored with guide Samuel Aarnio, who represents a younger generation that holds fast to the centuries-old sweat bathing tradition. Samuel and Mikkel start their sauna adventures in Helsinki and venture outward, island hopping by boat, visiting old friends for a traditional smoke sauna, and testing their limits in 60+ saunas at the Mobile Sauna Festival in Teuva. They even discover new ways of cooking meals by sauna, and indulge in the purity of a remote sauna village, deep in Finland's countryside.
