New study explains why men's noses are bigger than women's
Human noses come in all shapes and sizes. But one feature
seems to hold true: Men’s noses are bigger than women’s.
A new study from the University of Iowa concludes that men’s
noses are about 10 percent larger than female noses, on average, in populations
of European descent. The size difference, the researchers believe, comes from
the sexes’ different builds and energy demands: Males in general have more lean
muscle mass, which requires more oxygen for muscle tissue growth and
maintenance. Larger noses mean more oxygen can be breathed in and transported
in the blood to supply the muscle.
