Dr. Gordon Geisbrecht, PH.D
Dr Gordon Giesbrecht is a professor of thermophysiology at the University of Manitoba in Winnipeg where he runs the Laboratory for Excercise and Environmental Medicine, and studies human responses to excercise and work in extreme environments.
Gordon combines practical experiences as a wilderness instructor with 20 years of human cold research, conducting hundreds of lab and field trials which have led to the publication of more than 100 articles about cold physiology and pre-hospital care for human hypothermia. In 2006, Gordon teamed up with outdoors expert Jim Wilkerson to publish 'Hypothermia Frostbite and Other Cold Injuries'.
Gordon has been featured on the Discovery Channel, National Geographic and a number of television networks including David Lettermen's Late Show where he actually immersed himself in ice water on live TV to demonstrate the effects of Cold Water Immersion. He has also popularized the effective slogans 'one minute-ten minutes-one hour or 1/10/60' for immersion in icy water and 'Seatbelts-Children-Windows-Out' for escaping vehicles in water.

TO GORDON GIESBRECHT, the world's leading authority on freezing to death, a midwinter dip is just another day at the office. Believing that the best way to study the effects of cold on the human body is to get intimate with the elements, this 45-year-old physiologist and director of the University of Manitoba's Laboratory for Exercise and Environmental Medicine has lowered his body temperature below 95 degrees, the threshold of hypothermia, a mind- and body-numbing 33 times.
The masochism doesn't stop there. In March 2001, to learn more about how the body metabolizes various energy sources in subfreezing temperatures, Giesbrecht and four other men each dragged 180 pounds of gear across the frozen surface of Lake Winnipeg, a body of water roughly the size of New Hampshire, for 19 days. Then there was that winter 1999 experiment during which, in an effort to cool his body core while keeping his skin temperature constant, he had a colleague inject, over a one-hour period, more than a gallon of nearly frozen saline directly into his bloodstream. "He's a risk taker," says William Forgey, a 60-year-old physician who is the past president of the Colorado Springs-based Wilderness Medical Society. "If he needs to take it to the edge, he does it himself. While the expertise is there and the risk is controlled, it's still dangerous stuff. He's like a race-car driver."
There is, of course, a very good reason why Giesbrecht keeps getting behind the wheel: This winter, like every winter, athletes, adventurers, and hapless innocents will get themselves into trouble in the cold. While no organization keeps detailed statistics on cold-related deaths in the outdoors, each year hypothermia kills an estimated 700 Americans. An additional 1,800 or so are thought to perish in cold-water drownings.
Giesbrecht has devoted his academic career to improving the odds for such victims of exposure. He is Professor Popsicle, the King of Chill. He may have a cliché for every occasion—"Keep cool, but don't freeze," he'll say, smirking like Mister Rogers—but he is one of a kind. Or at least a few: There are roughly a dozen scientists worldwide who specialize in human thermoregulation, the study of how the body responds to temperature changes. Only a handful undertake human experiments, and no one goes as far as Giesbrecht, who has intentionally taken his core temp lower—down to 88.2 degrees—than any other researcher. "I'm the scientist who does things for real," he says, "to make sure I really know what I'm talking about."
