Exercising in the winter can help avoid some holiday weight gain and improve mental and physical well-being, but it should also be done right to avoid frostbite or hypothermia.

Eric Turner with Jet Physical Therapy in Washington says dressing for spending time outdoors this winter can vary depending on the kind of activity being performed, but he gives some advice for staying warm, “We need to be able to try to stay dry. If we have too many layers and we’re sweating that can eventually, if we continue to be outdoors, that can eventually make someone more cold actually. And then we need to have layers, or if we have layers on, not so bulky that you can’t move and be agile and perform activities in kind of a safe manner so we need to think about those things.”

Turner says it’s always better to wear too many layers rather than too little, as they can be taken off depending on the weather conditions. He also recommends wearing waterproof shoes with good traction in the case of slippery surface conditions, recreating with a friend, and carrying a cell phone in case of any safety hazards.
