If there is sauna with low humidity, it is of course ok. But going to a sauna world, where are many saunas with different temperature and humidity, but could be in the proper Finnish sauna only (where should be 10 to 20 %, of course if they properly control it, which does not happen always), is quite unpleasant.
Some saunas can be also outdoor, so you are going out and in. Everybody who wears glasses can confirm, that when you go inside from outside in winter, the glasses fog up. Of course, there are some situations when not, but it happens quite often. This is not theoretical exercise. I have already tried for you. Disposable contact lens are best.
