Big swaths of the country are trying to stay warm while on polar vortex watch this week. Temperatures have plunged way below zero across the Midwest, with cities such as Chicago seeing lows in the negative 20s and wind chills dipping even lower. If you're lucky enough to live anywhere else, these polar vortex photos and videos can give you a glimpse of what people are going through.

Simply breathing outside can hurt, and any exposed skin can sting in these frigid temperatures, The New York Times reports. School was cancelled in many districts, the U.S. Postal Service wasn't delivering mail, and workers in many offices were told to stay home. There have been at least six deaths connected to the weather, including two people who died in a car crash and one person who was hit by a snow plow.

If you're in one of the areas experiencing extreme cold, be sure to take precautions. "If you can't stay cozy inside, be sure to cover any exposed skin!" the National Weather Service tweeted earlier this week. "There's cold, and then there's COLD! Extreme and dangerous COLD! is forecast this week from the Northern Plains through the Great Lakes." These pictures show what that looks like IRL.
