If you go outside in the cold weather you should wear a nice warm sweater and a thick coat to keep your body shielded from the cold temperatures.
Wearing coveralls is another good way to stay warm and protect yourself from the cold and also wearing a stocking hat since a lot of heat escapes out of your head.
Keeping your head warm is essential especially in frigid temperatures.
Covering your ears with earmuffs and wearing a scarf around your neck is another good idea to keep yourself warm during cold weather.
During freezing temperatures only go outside for a little while at a time and take at least 30 to 40 minutes breaks to come inside the house or other warm building to keep warm again.
If you're outside in the cold temperatures gloves are also a must especially during below freezing temperatures since unprotected fingers can get frostbit in a matter of minutes during frigid weather.
