Age-20 sex-male. how often can i go for a steam bath in a week? i want to lose body fat.

It won't work: A person can lose a bit of weight after a steam bath, but it is almost all water weight and promptly regained. It has no role in permanent weight/fat loss. And there are risks: infection (germs thrive in that moist environment), severe dehydration, rise in core body temperature possibly leading to infertility in men. An occasional steam bath for relaxation is ok; dry heat/sauna is better.
