What's up with alarmist warnings that a hatless head will lose 50 percent of our body heat? Not true, says ftiness researcher Jolie Bookspan, writing on Healthline. Bookspan, who spent years studying how the human body performs in extremes, says head heat loss is usually less than one-third to one-fifth of total heat loss. But, she says, head heat loss increases as the temperature decreases. At 0 degrees Centigrade, up to 35 percent of heat could be lost through your head at rest. And head heat loss changes with how much you exercise. When exercising at about a work rate of 50 percent of aerobic capacity, head heat loss falls to less than half of heat loss at rest.
