The term “layering” gets bantered about with regularity when it comes to dressing for cold weather, but the mechanics of layering is often misunderstood and implemented improperly, resulting in frigid discomfort.
In order to understand how layering is supposed to work, you must first dispel with notion that clothes can make you warm. They can’t. The body actually generates the heat needed to keep itself warm, placing a particular emphasis on the heart and the brain. That is, if the heart or the brain starts cooling, the body will attempt to correct this by pulling heat away from the extremities. Our mothers knew exactly what they were doing, when they made us wear hats to go outside and play in cold weather!
