Does Climate Affect Human Height?


There is some evidence to suggest that climate may affect human height, but the effect is small and inconsistent. In general, taller people are found in colder climates while shorter people are typically found in warmer climates. This may be because tall people have more body heat than short people do, and cold weather can suppress this heat.

It has also been shown that there is a correlation between latitude and average heights around the world. This suggests that taller individuals tend to live closer to the equator where it’s warm year-round whereas shorter individuals cluster near the poles where it gets cold periodically. While these findings are interesting, they do not prove that climate affects human height directly or consistently.
