Winter is here, and red noses are aplenty. Big coats shield us from the icy cold, and boots work their hardest to keep our feet nice and warm. Still, the chill of winter wind sends a shiver through the body every time a breeze blows by just the right way. Logically speaking, it makes sense to think that between our bodies constantly working to keep us warm in the winter months, that the body would obviously burn more calories in cold weather – right?
Not exactly, but kind of.
Cold weather is not the sole deciding factor dictating whether or not our bodies go into calorie-burning mode. It’s more so the process our bodies undergo once we start shivering from a temperature drop. This process is called thermogenesis. One way of this happening is to shiver, which is when the muscles contract involuntarily in order to create warmth and help maintain a healthy body temperature.
