MADISON (WKOW) -- Wisconsin deer hunters had to deal with chill and wind for the opening day of the state's nine-day gun deer season.
The Department of Natural Resources reports about 616,000 gun deer licenses sold in 2013, with more female hunters registering this year.
Doctors are urging people to take precautions in the cold weather this weekend. They suggest people be careful not to wear too many layers when moving around a lot, to avoid the base level of clothes getting sweaty. That increases the chance of hypothermia and frost bite.
"I would try to do passive warming measures," says Dr. Eric Grube, with Mayo Clinic Health System. "Hand heaters. If you need to, you need to get out of the woods and start moving around, which will help circulate your blood through your extremities."
