While this, too, varies between individuals – one can usually stay in the sauna until they begin to feel uncomfortable. Typically, remain in the sauna for about 10-15 minutes and then take a break to cool off for several minutes. Then you can feel free to return to the sauna for another “inning.” A Finnleo sauna experience can be truly relaxing and rewarding, but don’t stay in the sauna for extended periods of time. Set the temperature and humidity level (if you are using a traditional sauna) to your ideal level. If you begin to feel dizzy or uncomfortable, simply leave the sauna and cool off.
