The competition begins with the sauna heated to a temperature of 230 Fahrenheit (110 Celsius)! Then, every 30 seconds, half a liter of water is thrown on to the sauna stove, which actually increases the heat. The last person to leave the sauna is the World Sauna Champion. Many contestants experience first degree burns from the intense heat. After the experience, some contestants may no longer even be interested in winning the competition prize--a sauna heater!
