Reconsidering the steam room

Ned's many friends may recall that he mused recently on the possible health benefits of regular visits to a steam room, since research has shown that breathing in a salty mist is good for one's sinuses. However, recently Ned has come down with two annoying minor sinus infections (here he is practicing medicine without a license, since he would never put his health in the hands of the medical cranks for such a minor complaint). He is now moved to wonder whether in fact the steam room may not be an incubator for germs of all stripes and persuasions, given the wet conditions and warm temperatures. Therefore, from now on he will confine his (all too few) leisurely moments at his gym--er, health club, to the salt water hot tub.
He will report on his findings at a later date.
