The coldest place on earth is not, as one might expect, in Antarctica or Siberia. Believe it or not, it is in southern England. Champneys health resort in Hertfordshire specializes in Cryotherapy, a medical therapy that uses extreme cold to treat everything from sports injuries and psoriasis, to depression and fatigue, according British tabloid the Daily Mail.

One staff reporter bravely volunteered to experience the extreme cold and reported from the Cryotherapy chamber at the resort.

According to the report, the temperature inside the chamber is an astounding minus 130 degrees Celsius. The lowest temperature ever recorded in a natural environment was minus 89 degrees Celsius at the Vostok research station in Antarctica in July, 1983.

The resort has even had some famous visitors. The report said that Tony Blair visited on the last Saturday in January before going back to his duty as Middle East envoy.

“He’s been here half-a-dozen times, I suppose,” said general manager Patrick Lemaigre.

Wrapped up in a mask, gloves and bandages, the reporter stayed in the chamber for about three minutes. He described getting out afterwards into a room of 20 degrees Celsius as feeling like “sizzling under the Caribbean sun.”

“It feels like I am walking on air,” he described of the feeling. “This is an endorphin rush far better than anything I’ve enjoyed after a gym session.”
