(CNN) - Schools in Minnesota are closing, Illinois' governor is warning
residents about hypothermia, and hundreds of flights have been canceled
at Denver Airport.

Even parts of the United States accustomed to cold weather are preparing
for the worst.

About 220 million people -- or 75% of the continental US population --
will endure below-freezing temperatures this week.

The biting cold already has caused at least one death in Minnesota and
another in Illinois. In many parts of the country, the coldest weather
is yet to come.

If you're 25 years old or younger, "you've never felt this cold before,"
CNN meteorologist Tom Sater said.

The winter storm has also led to the cancellation of 3,480 US flights on
Monday, Tuesday and Wednesday, according to Flightaware.com.

Across the Midwest and Great Lakes, the brutal cold will likely shatter
dozens of records, CNN meteorologist Dave Hennen said.

Between Tuesday and Thursday, temperatures will plunge to 20-40 degrees
below zero in the Upper Midwest and Great Lakes, Hennen said. Wind
chills will plummet to 35-60 below zero.

But the deep freeze is only half the story. The Dakotas are grappling
with blizzard conditions, the National Weather Service said. And heavier
snow is expected in the Upper Midwest and Great Lakes, meaning
"dangerous to impossible travel conditions."

Yes, wind chill is a real threat. It can and will harm you.

(CNN) - Do you ever walk outside, having just checked the weather, and
the wind punches you in the face?

The exposed parts of your body may feel like they're freezing. This
phenomenon is called wind chill.

That's right, the weather term isn't a myth. Wind chill is real, so
here's some facts to help you understand what it means and how to
protect yourself:

What is wind chill?

Wind chill is essentially how cold people and animals feel when they're
outside, according to the National Weather Service.

Wind chill is based on how much heat is lost from exposed skin while
it's windy and cold. The faster the wind, the more heat is drawn from
the body, which lowers the skin temperature and, ultimately, the
internal body temperature.

"The critical thing is how long you can expose your skin before
freezing," said Tom Sater, CNN meteorologist. "When the winds are
stronger, it can whip the heat away from your body quicker."

Wind chill only applies to people and animals, the NWS says. The only
effect wind chill has on inanimate objects -- such as cars or water
pipes -- is that it shortens the amount of time it takes for the object
to cool.

Why is it dangerous?

Wind chill can lead to frostbite, hypothermia and, ultimately, death.

Frostbite is caused by freezing of the skin and underlying tissues. It's
most common on the fingers, toes, nose, ears, cheeks and chin, according
to the Mayo Clinic. Severe cases can kill body tissue.

Hypothermia occurs when your body loses heat faster than it can produce
it, the Mayo Clinic says. Left untreated, it can lead to the failure of
the heart and respiratory system and, eventually, death.

How is wind chill measured?

Since weather/climate seems be your main interest, why not go and
study climatology, ecology and economics. Then you can come back
and tell us what you know, and 99% of people will just go right on

In western "culture" the short term
imperatives of self interest (individualism) drown out the long
term benefits of wisdom.

Most wisdom needs consultant fees sometimes our lives?
