If you plan to be outdoors this winter, shoveling snow, hiking, walking the dog, sledding or creating a snowman, dress in layers. When you are active, your body generates heat. Layers give you the flexibility to adjust your body temperature by removing or adding layers. And if you are looking for a great way to burn some calories and take in Central Ohio’s natural beauty during the winter months, check out one or all of the MetroParks winter hikes, beginning in January. Here is the schedule.
