Go for break once you feel you're done, go take a dip in a lake or roll in the snow (or a cold shower). After that, another 10-15 minutes in the sauna should feel nice. Repeat if you feel like it. Here in Finland, it's customary to enjoy a cold beer in the sauna as well (or more, but that kinda nullifies any health benefits). Cooling your mouth down makes the sauna experience better -- if you don't want a beer then sparkling water will also do the trick.
