Specialized Cameras Show How Your Body Responds to Cold

COLUMBUS -- Low temperatures can turn deadly for people who are not dressed properly, emergency officials warned during Monday's freeze.

Any exposed skin means heat is escaping the body.

Washington Township Fire Department has equipment to show exactly how this heat is lost.

"If you look through the camera you can see the white faces, the white hands," Tom Vagnier said. "You can see the heat coming through."

The crew tried an experiment: Firefighter Jack Egan wore all his winter fire-fighting gear while Lt. Greg Kelley wore a sweatshirt and pants before embracing the negative four-degree weather.

The camera showed heat loss where skin was exposed. The more layers on the body, the less significant the heat loss.

"The gentleman with just the sweatshirt, he was going down fast," Vagnier said.

In addition to layering up before going outside, it is important to stay hydrated, Vagnier said.

He also said one's overall fitness, age, and diet could influence a body's reaction to the cold.
