Cryotherapy chambers are a relatively new device. The machines use liquid nitrogen or electricity to chill a small enclosed space down to a mind-numbing minus 150 degrees Fahrenheit or even lower.

Cryo fans say you can boost your metabolism and burn anywhere from 500 to 800 calories by spending just three minutes in a cryotherapy chamber set to -306 degrees Fahrenheit.

With the cryo-chamber, one can exit it and start exercising within five-10 minutes. In addition, the effect of the treatment can last anywhere between six-eight hours.

If I wake up at 3:30, I can go to the golf course at 6:30, be done by 8:30, and then be home and then do the rest of my stuff: work with a physiotherapist, get treatment, hit the cryo chamber ...

Some cryo chambers have built-in screens that show a heat map of your body, so you can see yourself cooling down (or freezing, whatever you want to call it) in real time. Are there any risks? Um, yes.
