A: Sweating is a way for your body to thermoregulate. Your internal body temperature has to remain at around 37 degrees, with very minimal fluctuations. As a result, sweating allows your body to cool off when your internal body temperature gets above 37 degrees. This is why you can stay in the sauna and do absolutely no activity and sweat more than most people would who were doing an intense exercise. In this case, individuals are not “burning” calories but rather producing sweat which is mainly composed of water and salts. So next time you weigh yourself after an intense workout and notice you are a couple of pounds lighter than you were beforehand, remember that you most likely lost a couple of pounds of your water weight because you had to cool off through sweating! It is also important to note that thermoregulation is a big contributor to your fitness. The more fit someone is, the earlier and quicker they are able to sweat.
