Stars like Mandy Moore and minka Kelly are fans of cryotherapy. Dancers Derek hough and mark Ballas use it post-routine and even the king, Lebron James, takes to the icy chamber so why do they do it and should you? The makers of this claimed it first gained traction as a post-recovery plan and found applications for improving skin tone, reducing the signs of aging and even managing pain. All of the blood vessels in your arms and legs constrict and then when you come out, all that blood rushes back and in doing so it also releases endorphins and endorphins are your own body's way of managing pain. Reporter: The chamber is filled with icy air as low as 290 degrees below zero. And once you step in, you chill down for up to three minutes and results are supposedly instant.

I was freezing but the other thing a few minutes after you get out the blood rushes back in and legs from my waist itched so badly I came back in and thought my legs were falling off so it's pretty amazing. I did feel revitalized afterwards but you should always consult a doctor before trying something like this because patients with high blood pressure or heart conditions probably shouldn't be doing this.
