Instead of sitting in a tub of ice for 15 minutes, his company — Millennium ICE — has manufactured a machine called the Cryon-X that claims it can do better in three minutes.

While surrounding temperatures in an ice bath only get down to about 40 degrees Fahrenheit, Rauscher's device uses liquid nitrogen to crank the surrounding temperature up to minus 166 degrees Fahrenheit.

Rauscher says the device works on recovery because the body triggers its flight or fight response in order to try to maintain its temperature in the extreme cold. During that time, the blood rushes to the core and becomes oxygen-enriched.

When the person exits the device, the body immediately circulates that blood throughout the body. This helps decrease fatigue, muscle soreness.

Athletes have famously used hyperbaric chambers (oxygen therapy) to help them perform, so is this the next big thing?
