Steam and sauna

I’ve been using a steam room for a few months. I go about 3 times a week for 15 minutes each time.

I really don’t know what the hell I’m doing but I like to sweat bullets with no effort. It makes me feel as though I’ve done something. I feel relaxed when I finish too.

Wondering though what the actual health benefits are and how often I should be doing it or if I need to limit it or cut it out completely. I read some stuff about harm to adrenal glands due to the loss of fluid.
