As for being able to lose weight, this is even more impossible, because the advertisement itself is distorting the concept-first of all, it is said that exercising and sweating can lose weight. Exercise and sweating consume energy during exercise, so our body will decompose fat by itself, convert fat into glucose, and then absorb water from body muscle tissue and excrete it. This statement that "exercise and sweating can reduce fat" is scientific, and the advertisement that their products can replace exercise is obviously untenable. Because although you can sweat with "really relaxed", most of this "sweat" belongs to the steam generated by the machine and stays on people's skin, not the real "sweat". Even if there is sweat, it is a "cooling water treatment" that people do in order to reduce the body temperature in a high temperature environment, which is completely different from the sweat produced during exercise ~ ~ ~
I suggest you don't believe TV advertisements, which are generally false.
