Whether waiting for a bus, playing outside or walking the dog – during the colder winter season, everyone is looking for ways to stay warm. Luckily, the process your body uses to break down foods serves as an internal heater.
If you’ve ever had to work in a draughty office, warehouse or classroom, you’ve probably been tempted to keep your coat on inside. And you were probably also advised against it because you wouldn’t “feel the benefit” when you went outside. This might seem counter intuitive. If you’re cold already, surely you should do whatever you can to retain warmth? It turns out things aren’t that simple. To understand what’s really going on, we need to know a bit about why we feel cold in the first place.
