As the temperature difference between your warm body and its frigid surroundings increases, heat is lost more quickly.

The process your body uses to break down foods serves as an internal heater.

When you enter a cold environment, your body redistributes blood to the torso, protecting and maintaining the warmth of the vital organs there.

Your body constricts blood flow to the skin, so less is lost to the environment.

Being physically active causes your muscles to contract, breaking down more nutrients, which generates additional heat.

The cold air saps the heat from your skin and your sweat evaporates.

To stay comfortable, your best bet is dressing appropriately, whether inside or outdoors this winter .
