Hi All, I've heard that sauna & cryotherapy (hot to cold) treatments can benefit autoimmune conditions as well as some skin conditions (psoriasis / eczema). Wondering if anyone has tried either or both of these and if you saw or felt any improvement in symptoms? I've read it can help with itching and slow regrowth. Willing to try as it's low risk - would love to hear from any of you who have tried.
