a technique developed by U.S. Army researchers in Alaska. In a room that's a comfortable temperature, submerge your hands in a container of warm water for three to five minutes. Then go into a freezing room (outside in wintertime unless you have access to a walk-in freezer) and again dip your hands in warm water for 10 minutes. The cold environment would normally make your blood vessels constrict, but the warm water makes them open. Repeatedly training vessels to open despite the cold around them may enable you to counter the restriction reflex even without the warm water.
