These brittle temperatures and relentless snow storms can really have a physical toll on the body. Among many, two common effects of the cold weather are frostbite and injuries from shoveling snow.

Frostbite is a medical condition where "localized damage is caused to the skin and other tissues due to extreme cold." Typically it can be seen in body parts farthest from the heart and in large exposed areas.

Factors that contribute to frostbite include extreme cold, inadequate clothing, wet clothes, wind chill and poor circulation caused by tight clothing or boots, cramped positions, fatigue, medications, smoking, alcohol use, or diseases affecting the blood vessels.

To treat frostbite, you should slowly warm the area by going inside, covering with blankets and warm clothing. If frostbite is further progressed, it might require medical attention.

According to HealthDay News, snow shoveling injuries cause an average of 11,500 injuries and 100 deaths per year, effecting both adults and children. The most common injury is the back, followed by arms, hands and the head.

Heart problems are also common, more typical with adults age 55 and older and among men.  Freezing temperatures contribute to the cardiovascular demands of snow shoveling. The heart's workload is increased, especially if it is not conditioned for strenuous shoveling, adding to the chances of a heart-attack in at-risk individuals. Chest pain in women is atypical. If you are experiencing chest pain while shoveling, stop immediately and seek medical attention.

It is important to stretch before shoveling, be careful not to lift too much snow at one time, bend your knees when scooping the snow and take breaks. If you are at high-risk for heart issues, consult a doctor prior to shoveling.

During these winter months, it is important to bundle up in , wear appropriate outerwear to keep your body warm and be extra cautious with shoveling and outdoor activities.
