Here are a few tips on how to keep your body free of pain this winter. 1. Check your shoes. Has the tread started to wear down? Falls on ice and snow can be prevented with the right footwear. 2. Stretch. Stiff muscles can make it hard to move freely, and if you trip or fall, your back is likely to be in far more pain than it is now. 3. Stay warm. This is critical to keeping your back healthy—or keeping your back injury from getting worse. Cold weather is one of the causes of joint pain and tense muscles.
