Be aware of the signs of frostbite – Frostbite occurs when skin is exposed to extremely low temperatures and can lead to permanent damage. Common symptoms include white or grayish-yellow skin, numbness and joint and muscle stiffness.

Avoid getting gasoline on your skin – If you’re operating a snow blower or fueling your car, be sure not to get any gasoline on your skin. It can cause your body to lose heat more quickly.

Dress warmly – In addition to hats, gloves, boots and scarves, dressing in layers will help your body retain heat. According to the CDC, wool, silk and polypropylene fabrics trap heat more effectively than cotton. 

Avoid exerting yourself – Low temperatures can put an additional strain on your heart and excessive sweating can cause your body to lose heat, according to the CDC. Refrain from performing difficult outdoor chores, if possible.
