Ten schools were delayed and one was closed Monday because of the single digit temperatures and the wind chill factor.

Even though the sun was out you could hear the wind howling and only a few people were not sitting in their vehicles with the heat on at Civitan Park Monday afternoon.

It was the wind that made it feel colder outside and Doctor Ernest Miller of the Mid-Ohio Valley Medical Group recommends being prepared to stay out for awhile even if you aren't planning on it.

First he says dress for the weather. Wear a coat, a Gortex or nylon one if you're going to be out for a long period of time to protect yourself from the wind.

Also wear mittens, layer clothing, and put on appropriate footwear.

If you're going to a holiday party, a drink could even make you feel colder.

"Well alcohol it might make you feel good for a little while because it dilates up your blood vessels but overall it can drop your, if your extremities if you dilate blood vessels in your hands and feet. They cool rapidly and it can drop your central or core temperature low and you can become very cold very quickly that way," he said.

Wearing a hat is important Dr. Miller said because you can lose up to 30 % of your body heat through your head. Not bundling up could lead to hypothermia.

All in all he recommended being prepared to stay outside for a long time even if you aren't expecting to.

Some people's extremities can go numb when the temperatures drop below 35 degrees Farenheit. It's a condition called Raynaud's disease.

"The blood vessels constrict in the hands or feet will turn blue then pale and then when they dilate back up they get real red and that's when you get the pain," said Dr. Miller.
