Does cryosauna have cosmetic, psychological, or neurological benefits? Despite many claims of improved skin and cellulite etc., there is no evidence for its cosmetic usefulness—not even bad evidence. There is no evidence of any kind that it has a lasting effect on circulation, nervous function, depression or any other health issue. Promoters claim a myriad of health benefits, but provide no actual evidence, not even minimal anecdotal evidence. Overall, despite marketing statements that might sound like scientific evidence, WBC is physiologic nonsense that, as is sadly too common, oversimplifies how the human body works.
