FROSTBITE
Millions of Americans will take to the outdoors this winter. The health benefits of winter sports are numerous. The release of endorphins elevate mood and help ward off "cabin fever." Engaging in winter sports burns more calories than equivalent warm weather activites as it takes more energy for the body to maintain its body temperature in colder environments. But exposure to cold temperature, wind and wet weather may lead to freezing of the skin and underlying tissues, a condition called "frostbite."
