With another wave of dangerous cold heading for the U.S. South on Friday, experts say the risk of hypothermia heightens for people in parts of Mississippi and Tennessee who are entering their sixth day trapped at home without power in subfreezing temperatures.
“The longer you’re exposed to the cold, the worse it is,” said Dr. Hans House, a professor of emergency medicine at the University of Iowa. “The body can handle cold temperatures briefly very well, but the prolonged exposure is a problem."
