    (CNN)Would you dare to freeze yourself fit by stepping into a chilling chamber colder than Antarctica?

    Golfers are used to frosty fairways, stormy tees and soggy greens but Padraig Harrington is taking the plunge with a real deep freeze.
      Ireland's three-time major winner is following in the chilling footsteps of actor Daniel Craig and super-fit soccer star Cristiano Ronaldo by exposing himself to cryotherapy in preparation for the 2015 season.
        "I've used whole body cryotherapy for several years," Harrington commented to CNN.
        "Guided by research from Setanta College, it's played a key part in my recovery, especially between competitive periods."
        Cryotherapy translates as cold cure -- but for some the intense chill goes beyond words.
        "The cold floods your brain and you can't process much more than putting one foot in front of another," Mike Moynihan, a columnist for the Irish Examiner, recalls of his experience in the chiller.
        "Your body is in revolt and won't allow you to relax. It's so different, to be that cold, that I had a real notion of what people mean when they refer to a hostile environment -- but that only came afterwards, when I was outside."
        Chill with a thrill
        For others, cryotherapy is an ecstatic chill with a thrill.
        "I call it 'legal doping,' says Eduardo Bohorquez, who runs New York's only cryotherapy center. "When you come out you feel so euphoric."
        Those brave enough to enter the cryotherapy chamber expose themselves to tingling temperatures of -130 degrees Celsius or -200 Fahrenheit.
        That makes Antarctica -- where NASA recorded the coldest spot on earth as -92 degrees Celsius at the end of December 2013 -- officially warmer.
