There's a reason putting ice on an injury works. That drop in temperature reduces inflammation in, say, a sprained ankle or stubbed toe. But the theory works on a much grander scale, too -- cold temperatures can reduce inflammation and pain all over.
In fact, athletes and spa-goers even have a remedy of sorts available for muscle recovery. A 2011 study found that, at extremely low temperatures, such treatments, called cryotherapy
, did more for athletes to recover from physical activity than simply resting. Runners who were exposed to temperatures as low as -166 degrees F recovered from exercise faster than those who given other therapies or told to rest, The Atlantic reported.
At spas, cryotherapy chambers appear much like steam rooms -- with, of course, the opposite effect. And while the majority of us probably won't be taking a trip to the cold room
, it certainly beats summer swelling!
