saunajuoksu
Saunajuoksu, translating to "sauna running" or "sauna sprint" in English, is a unique and demanding physical activity that combines the practice of sauna bathing with short, intense bursts of running. The core concept involves alternating between periods of intense heat exposure in a sauna and strenuous physical exertion, typically running. Participants may enter the sauna for a short duration, experience the heat, and then immediately exit to perform a run, often around a designated circuit or track. This cycle of heat and exercise is repeated multiple times, pushing the body's endurance and heat tolerance to its limits.
The origins of saunajuoksu are not widely documented but it is often associated with Finnish sauna culture
