Why don’t I sweat in the sauna?
KLAFS FAQ for well-being
There could be various explanations here. First, it could be purely technical – was the sauna cabin preheated for an adequate amount of time? If not, heat will not radiate sufficiently from all sides, and you’ll only feel the heat close to the heater itself. Or were your hands and feet cold when you entered the sauna? If so, your whole body will need to get up to temperature first, so there will be less time left to sweat properly. Or perhaps you didn’t dry off properly before entering the sauna? In this case, your body didn’t need to evaporate any moisture of its own – the moisture was already there on your skin. And in any case, the amount you sweat is highly individual. Men sweat more and faster than women. Sweating is also a matter of practice. If you find you don’t sweat much at first, or you often feel hot anyway, you can train your body to sweat by using the sauna regularly. You can feel the effect of such “training” almost instantly – most people sweat far faster during their second round in the sauna. Frequently, however, it’s quite simply that the air is so dry at first that it’s able to fully and instantly absorb all the moisture on your skin. You are sweating – you just can’t see it forming on your skin. In other words, “no sweat” isn’t quite the same as “no moisture loss”.
