sauna's for detoxing?

someone mentioned in one of my posts that i should use the sauna for detoxing. i thought i read somewhere that this could be bad with candida. is it good or bad. anyone know?

also, does anyone know how much salt you should put in a detox bath. anything else i should add to the bath besides salt? i take baths a few times a week but haven't been putting anything in them and i figured it was time i started. thanks!
