The good news is that your perception of temperature changes with the seasons. When we get that first bit of cold air, it feels awful, said John Castellani, a physiologist at the U.S. Army Research Institute of Environmental Medicine in Massachusetts. And then in March, you get that same temperature and it feels like it's time to go play golf. These changes start happening within about ten days of exposure, Dr. Castellani said.
Military researchers have gone to great lengths trying to help soldiers adapt to winter weather, with little success. A few people—the polar swimmer Lewis Pugh, for one—have demonstrated extraordinary cold tolerance, but they seem to be outliers. I don't dispute what they can do, said Stephen Cheung, an environmental physiologist at Brock University in Canada. But I don't think there are lessons that we can learn from them and apply to ourselves.
