(WZZM) -- With temperatures in the single digits and lower, it's important to really bundle up against the cold.
It only takes a few minutes to get frostbite if you're out in the elements, that's why you have to create a sealed envelope of air around your body.
A thermal camera shows which body parts let the most heat escape when outside. The head, face, and neck give off the most heat, but body heat also escapes from inside your jacket along the zipper and seams.
To keep that heat trapped, wear several thin layers and a scarf made of wool or synthetic fibers under your coat's zipper.
Losing too much heat can lead to frostbite or even hypothermia.
If you remove your glove in this cold, it takes less than one minute for the body heat to disappear. The fingers lose heat first as the body draws the heat toward your core to protect your essential organs.
Remember, your fingers, toes, nose and ears are the most vulnerable to frostbite.
