Good Morning Boys and Girls. Mrs. Ferrara here with your Physically Fit health tip. Knock. Knock. Who’s there? Frostbite. Frostbite who? Frostbite your food and then chew it. :) Good-bye Polar Vortex. Hello warm weather this weekend. But today, boys and girls, it’s cold outside. Has Jack Frost nipped at your nose? Actually, frostnip is a very real type of injury caused by exposure to cold temperatures. It is a milder version of the better known frostbite. Frostbite occurs when body tissues literally freeze. Usually this happens to skin tissue, but sometimes deeper body tissues. Kids are at greater risk for frostbite and frostnip than adults. This is because kids lose heat from their skin faster than adults. Another reason is that kids are usually having way too much outdoor fun to notice that they need to go inside and warm up.
Frostbite develops in extreme cold within minutes. It can affect any area of the skin. It is a serious condition that requires emergency care. Signs of frostbite include pain or numbness of the hands, feet, face and ears. The skin feels hard and waxy and has a white or grayish-yellow color. Bedside extremely cold temperatures, wet clothing, high winds, and poor circulation increase your chances of developing frostbite. Poor circulation can happen when clothes or boots are too tight. It can happen if you stay in a cramped position for too long or even when you are tired. Some medicines can cause circulation problems.
So what can smart, responsible 4th and 5th graders do to prevent frostbite when you go outside? It’s pretty clear that you should wear warm clothing. A coat, hat, scarf, gloves or mittens are essential when you go out for recess. Dressing in layers is the way to go. The first layer of clothing should keep moisture away from the skin. Thermal long johns and undershirts, cotton socks, mitten or glove liners are best for layer number one. The second layer should be loose clothing that resists dampness. Things like heavy pants, sweaters or a sweatshirt. Finally, layer number three means tightly woven, moisture resistant outwear – your coat, jacket, hat, scarf, boots, gloves or mittens. Another smart way to prevent frostbite and frostnip – go inside at intervals and have an adult check your fingers and nose for signs of exposure to the cold weather. Also, you may want to eat a handful of cherries to boost your immune system!
We are lucky that we don’t live in Frostbite Falls, Minnesota. Do you know who does live there? Stop by and tell me if you know the answer. I will leave with this MATH problem about cold weather. If it is zero degrees outside today and it is going to be twice as cold tomorrow. How cold is it going to be? Stay warm and have a physically fit Friday.
