Business Insider at KryoLifeBusiness Insider reporter Graham Flannagan inside KryoLife's cryo-chamber.Nestled in midtown Manhattan, just a couple blocks south of Central Park, is a self-proclaimed health and wellness center called KryoLife, where clients are blasted with super-chilled air that's between minus 184 and minus 264 degrees Fahrenheit.

They like it so much, KryoLife co-founder and CEO Joanna Fryben told Business Insider, that over 90% of first-timers come back a second time.

The chilly experience is widely used in Europe to relieve certain types of pain and is growing increasingly popular in America, especially among professional athletes and celebrities.

To see for ourselves what all the fuss was about, Business Insider sent a few of our reporters to the center where Graham Flanagan took one for the team.
