Champion jockey Tony McCoy is the latest high profile sports star to turn to kriotherapy to help speed up a return from injury.
The so-called "ice chamber treatment" sees the patient spend up to two and a half minutes in temperatures as low as minus 130c.
It has previously been used by international rugby players, footballers and jockeys and its reputation is growing.
Kriotherapy, popular in Japan and Poland, works by stimulating the hormone system and enhancing blood circulation, leaving the patient feeling extremely alert.
In addition to helping recovering athletes it has been used to help people suffering from depression.
