People have carried burdens balanced on top of the head since ancient times, usually to do daily work, but sometimes in religious ceremonies or as a feat of skill, such as in certain dances.
In Ghana, affluent residents of the southern cities employ young women who migrate from the poorer northern region to work as "head porters", called kayayei, for $2 a day.
The research did not support the notion that head-loading is less exerting than carrying on the back, "although there is some evidence of energy saving mechanisms for back-loading at low speed/load combinations".
One observer during the American Civil War noted the impressive sense of balance and dexterity that the practice gave women in South Carolina: "I have seen a woman, with a brimming water-pail balanced on her head, or perhaps a cup, saucer, and spoon, stop suddenly, turn round, stoop to pick up a missile, rise again, fling it, light a pipe, and go through many revolutions with either hand or both, without spilling a drop".
[6] Until the turn of the 20th century, African-American women in the Southern states continued carrying baskets and bundles of folded clothes on top of their heads, when they found work as washerwomen, doing laundry for white employers.
[7]Head-carrying was used in London's Covent Garden market in the late 19th century, with porters competing to carry up to 15 stacked baskets on their head.
[8] In describing "the most cosmopolitan fruit market in the world" just before the Great Depression in the late 1920s, the United States department of Agriculture said the porters carried produce on their heads, backs, or in barrows.
They were told to model themselves after "the Egyptian water-carrier, with the jug of water poised so prettily on her head, and her figure so straight and beautiful".
