Inuit Sweat Patterns Favor Faces

In 1974, researchers compared 37 Inuit men with 21 white men and found that the Inuit participants had more active sweat glands on exposed facial areas, including the nose and cheeks. Their trunks and limbs, which Arctic clothing normally covered, showed much less sweat-gland activity. The researchers suggested that this Arctic adaptation could allow the exposed face to release heat during exertion while heavy clothing covered the rest of the body.
