TUESDAY, Jan. 28, 2014 (HealthDay News) -- As the Northeast and
mid-Atlantic joined the Midwest in dealing with yet another deep
freeze on Tuesday, doctors are offering advice on dealing with
"It's best to limit your outdoor activity as much as possible, since prolonged exposure can lead to frostbite and hypothermia," Dr. John Marshall, chair of emergency medicine at Maimonides Medical Center in New York City, told HealthDay. "Both of these conditions can become serious, and even life-threatening, if untreated."
By Tuesday morning, many regions of the United States saw
temperatures plummet for a third time this winter,
The Weather Channelreported.
Even the South will not be spared, according to
USA Today: A rare winter storm is expected to dump ice and
snow from Texas to Virginia Tuesday and into Wednesday.
"Very hazardous travel is likely across a long swath of the South . . . in the Tuesday to Wednesday timeframe," reported Weather Channel meteorologist Nick Wiltgen.
When the weather turns this wintry, there are many simple
safeguards you can take to prevent severe injury, Marshall
When you're out in the cold, the part of your skin that's
exposed will chill rapidly, experts say. This can lead to decreased
blood flow and your body temperature can drop, leaving you
susceptible to frostbite and hypothermia.
According to Marshall, frostbite "starts with tingling or
stinging sensations. The face, fingers, and toes are the first body
parts to be affected. Then muscles and other tissues can become
numb." Additional signs of frostbite include redness and pain in
the skin. This can lead to discolored and numb skin, he said.
Hypothermia, which often goes hand-in-hand with frostbite, can
affect the brain, making it harder to think clearly. Warning signs
of hypothermia include shivering, confusion, slurred speech and
drowsiness, Marshall said.
"If any of these symptoms become noticeable, you should protect the exposed skin, get to a warm place and seek immediate medical treatment," he said.
Some people are especially vulnerable to the dangers of cold
weather. They include the elderly, those with diabetes, heart or
circulatory problems, and people who use alcohol, caffeine or other
drugs that inhibit the body's ability to protect itself against the
Dr. Robert Glatter, an emergency medicine physician at Lenox
Hill Hospital in New York City, said there are several key factors
that determine how long people can endure extremely cold
temperatures. Those factors are wind speed, how well a person is
dressed, and if their skin is wet or moist.
Dressing in layers may help. Use the "three-layers guideline" to
provide more effective insulation. The first layer helps to drain
moisture or sweat. The second layer serves as insulation, while a
third sturdy outer layer can help to block out the cold, Glatter
If you think you or another person is suffering from frostbite,
get to a health-care professional as fast as possible or call 911.
If you can't get immediate medical help for at least two hours,
re-warm the affected area with warm water. And drink warm,
non-alcoholic fluids, Glatter said.
Cindy Lord is director of the physician assistant program at the
Frank H. Netter MD School of Medicine at Quinnipiac University in
Hamden, Conn. She likes to use the acronym C.O.L.D. when advising
people on dealing with the cold.
And for those who will have to venture out to shovel snow from
driveways and sidewalks in the coming days, Lisa Hoglund, a
physical therapy professor at University of the Sciences in
Philadelphia, offered this advice:
