I am just curious as to if anyone has used these saunas to induce fever and if it has helped... I think my immune system is really messed up. Before the illness that caused my ME/CFS (in 2008) i was sick a lot. Like 4-6 times a year with chronic sinus infections. This lasted from around the age of 6 to my late 20s. (I'm 37 now). The Drs used to treat me with antibiotics like it was candy. I have spent the last year and a half rebuilding my gut flora and really focusing on specific flora for helping promote a good balance. Now I'm going to get tested for chronic viral infections to see if this is an issue for me. One major problem is that i run cold. I never get a fever and if i do its only a degree or two above normal. I'm not sure why this is. But I'm wondering if this is why i kept getting sick and not really recovering. I'm thinking about trying a heat sauna to induce fever as a therapy but I'd like to hear if anyone else has tried it and what their experience was. Does anyone know if viruses or bacteria could prevent you from getting a fever as a defense mechanism? Does that happen? Just curious... thank you!
