Athletes have been taking ice baths forever to relieve sore muscles and improve circulation, but could taking it one step further (and about -150 degrees colder!) have big benefits?

Dr. Ian stopped by to dish on the latest health trends, and cryotherapy was at the top of his list!

At its simplest, cryotherapy is all about exposing yourself to super-cold temperatures in a controlled environment, but instead of dipping into an ice bath, you enter a cryotherapy chamber or sauna, which is cooled by nitrogen.

And temperature is anywhere from -200 to -250 degrees!

Yes, you read that right!

Spend just two or three minutes in the chamber, and Dr. Ian says it’ll trigger a series of physiological responses in your body.

“It basically reduces your body’s temperature and can increase your circulation [and] your endorphins, which are your body’s happy chemicals, says Dr. Ian. “And it is also good for arthritis and joint pain.”

But, while that all sounds well and good, remember this: If you have any underlying health conditions, including heart disease, hypertension, high blood pressure or diabetes, you should check with your doctor first.
