I am thinking heavily of getting a personal steam sauna (not FIR). I heard these were especially good for Bio-toxin illnesses such as Lyme etc. I contracted Tyhus a while ago which is akin to Lyme in some ways. My only concern is replacing the lost minerals I am sweating out with the sauna. Already I have poor absorption and my mineral levels need building up, but sweating out will decrease some minerals even further. My doc said it was OK and she just said,"remember to replace electrolytes", but that was it. Any comments on replacing minerals or sauna therapy in general?
