MONDAY, Jan. 6, 2014 (HealthDay News) -- The record-shattering cold weather that's gripping much of the United States can pose extreme health risks, doctors warned Monday.

"It's best to limit your outdoor activity as much as possible, since prolonged exposure can lead to frostbite and hypothermia," said Dr. John Marshall, chair of emergency medicine at Maimonides Medical Center in New York City. "Both of these conditions can become serious, and even life-threatening if untreated."

The extreme cold, which meteorologists blamed on a "polar vortex," extended from Montana to Alabama on Monday afternoon and was expected to slam into the East Coast Monday night. Wind-chill readings were projected to be minus 55 Monday night in International Falls, Minn., before "rebounding" to minus 25 to minus 35 on Tuesday. A bit farther south, the wind chill was expected to hit negative 50 in Chicago and minus 35 in Detroit, the Associated Press reported.

When temperatures drop that low, there are many simple safeguards you can take to prevent severe injury, Marshall said.

They include:

  • Dress warmly. Layering your clothing will provide the best insulation and retain body heat. Wearing a non-permeable outer layer will minimize the effects of strong winds.
  • Protect your extremities. Hands and feet are at greater risk of frostbite because body heat is naturally reserved in the torso to protect vital organs. So wear an extra pair of socks, and choose mittens instead of gloves because fingers stay warmer when next to each other.
  • Wear a hat. You lose about 30 percent of your body's heat from your head. Particularly good are hats that cover the ears and nose.
  • Wear properly fitted winter boots. Boots that are too tight can limit or cut off circulation to the feet and toes. Also, choose a boot that's insulated and has treads on the bottom because treads provide traction on ice and snow.
  • Stay hydrated. The body uses a lot of energy to keep itself warm. Drinking plenty of fluids is important because your body will need frequent replenishing when fighting off the cold.
  • Get out of wet clothing as soon as possible.
