01:20 How Long Does it Take to Get Cold? The Weather Channel meteorologist Alex Wallace finds out just what it is like to be in below freezing temperatures for an extended period.

Hypothermia has been blamed for the deaths of at least 22 people as an arctic blast, known as the Siberian Express, continues to push through the central and eastern parts of the U.S.

The toll includes 11 people in Tennessee, six in Pennsylvania, two in Illinois and one each in Indiana, Ohio and Kentucky. Several other deaths suspected of being related to the cold are still being investigated.

In addition, Canadians are mourning the death of a three-year-old boy who wandered out into extreme cold in Toronto this week and was later found dead of exposure according to The Weather Network, Canada's equivalent of The Weather Channel.

"This week ranks among the most intense arctic outbreaks so far in the 21st century for the eastern U.S., and it is certainly one of the most impressively cold air masses we've seen this late in the winter season, coming only a month before the spring equinox," says weather.com senior meteorologist Nick Wiltgen.

At least 500 daily record lows have been broken since Sunday, according to figures from NOAA's National Climatic Data Center and the National Weather Service. More record lows are expected Saturday morning in the Northeast.
