The good news is that time spent in a sauna can actually help you lose weight. The bad news is that the weight you lose in a sauna is almost entirely water weight caused by heat-induced sweating.
Though many manufacturers of saunas tout their weight-loss powers, there is little science behind the idea that saunas magically make you burn fat or otherwise lose weight.
In this article, we’ll look at the scientific evidence regarding weight loss and saunas, and the quality of that science (spoiler: it’s not good). For those who are simply looking to cut a few pounds of water weight temporarily, we’ll also look at how to sauna for weight loss.
