Saunas are generally a hot/cold cycle. Sit inside for 5-10 minutes, then cool off with a cold shower, a dip in the pool or just resting outside for a bit. Then you can re-enter the sauna.
It is not an endurance test. It is best to be guide by how you feel.
As you gain more sauna experience, you may build endurance and be able to stay longer.
When using the our Tylo Combi "steaming" heater, you can often stay longer as the heat is less intense.
