Spotted this posted in an empty storefront as I went about my day today. The web site shown on the poster does not appear to be active, but this description of cryotherapy from another spa sounds pretty awful:
“Therapeutic exposure of the entire body to extremely low temperature for up to 3 minutes duration. Body surface is cooled by vaporized liquid nitrogen that surrounds the body at temperature between -190 to- 256 F. During this process a systemic anti-inflammatory response is triggered that reduces inflamation, improves circulation, boosts body’s metabolic rate and invigorates the mind.”
