It's a fact the arctic blast has settled over Indiana, but not everything you hear about cold weather is true.
The numbers, as low as they are, don't lie. But the cold blast brings some pretty tall myths that have become widely held beliefs.
For example, you wouldn't think about going outside without a hat because an exposed head is where the body loses most of its heat, right?
That's just one of the myths debunked in books written by Doctors Aaron Carroll and Rachel Vreeman, two pediatricians and researchers at Indiana University School of Medicine.
In the follow-up to their 2009 hit book, "Don't swallow your gum!: Myths, half-truths and outright lies about your body and health," the doctors tackle the hat for heat in cold weather.
Research shows that you don't lose any more body heat from an uncovered head than you would from an uncovered arm or leg.
And, you can't get a cold from being in the cold too long.
Cold aren't caused by weather, but by rhinoviruses. Still, separating fact from fiction won't make the weather less dangerous with the extreme cold hanging on.
