It almost seems too simple to be true, but research shows submerging your forearms and biceps in ice cold water can prevent overheating. It's a technique the U.S. Army has embraced at bases across the country.
"It's low-tech, it's inexpensive, it's easy to implement," said Lt. Col. Dave DeGroot, who runs the Army Heat Center at Fort Moore. "It's a bucket of water."
When immersed for five minutes, an ice bath can lower core body temperature by as much as 1 degree Fahrenheit. Given that normal body temperature ranges between about 97 and 100 degrees Fahrenheit, one degree of internal cooling makes a significant difference.
