Everybody's heard about athletes taking ice baths after a hard game, and it sounds like a nightmare. KryoVitality delivers the benefits of the extreme cold without all of the discomfort of spending an hour in it. Here, athletes, runners, and people with overworked muscles spend between 30 seconds and 3 minutes in the cryotherapy chamber. The temperatures plummet to a staggering -240 degrees, which chills the muscles but doesn't affect core temps. The short treatment is long on benefits, including improving resistance to muscular fatigue, boosting immunity, and increasing empathy for penguins. The sessions also provide a number of immediate cosmetic benefits by burning between 500 and 800 calories per session, tightening skin, and reducing wrinkles. For those reasons, cryotherapy has been used by celebrities including Demi Moore, Jennifer Aniston, and Victoria's Secret models.
