When is it “Too Cold” for Outdoor Activities?

Never. According to a recent article in the New York Times.

At least that’s what Dr. John Castellani says. He’s an exercise physiologist and expert on environmental medicine. “The big question was, ‘Is it ever too cold?’” Dr. Castellani said. “The answer is no. People go to the poles, people are out there when it’s minus-50 degrees, people do incredible things, and safely. There really isn’t a point where you can tell people it is not safe anymore.”

Common Myths…

Bundle Up
Yes, wear enough clothing to keep you warm. Try not to leave too much exposed skin. But don’t overdress. Wearing too much can make you sweat and sweating can keep you wet and eventually cold.

Take Breaks
No way. Keep moving, this will keep you warm. Stopping will only slow your heart rate and make you colder.

It Can Damage Your Lungs
Wrong. By the time air reaches your lungs it is body temperature, says Kenneth W. Rundell, the director of respiratory research and the human physiology laboratory at Marywood University. However, cold air can sometimes be dryer. So if you experience any problems it is most likely due to the dryness of the air, not the coldness.

With all that said. Hypothermia and Frostbite are real. Don’t stay out too long or expose yourself to extreme conditions for long periods of time. But moderate exercise in cold weather is just fine. Well, there goes that excuse. I guess I should get outside and do something…
