Given recent reports on the strain caused by heavy backpacks, you might be looking for an alternate way to schlep your belongings around. One time-honored option used in many cultures is to carry items on the head.
But despite what they may have told you in finishing school, carrying items on your head may not be the most efficient mode of transport, according to a new study. A team of scientists working in South Africa and Scotland set out to test whether a small previous study that seemed to recommend head-loading could be replicated with a larger sample. Carrying heavy loads on your head certainly frees up your arms for other uses, but as the researchers discovered, it no more efficient than carrying weight on your back and can lead to neck pain.
In South Africa, the team analyzed the movement and weight-bearing of 24 Xhosa women–13 of whom had over 10 years of experience carrying loads on their heads and 11 of whom had no previous experience. The women walked on a treadmill while carrying either no weight, weight on their back, or weight on their heads. They compared these results with those observed in 9 British women serving with the British Territorial Army who were experienced in carrying heavy loads in backpacks.
All of the women used roughly the same amount of energy, regardless of which transport mode they tried. Carrying items on the head was considered the most difficult option by the participants, and did not seem to get any easier with experience. In addition, the more experienced head-carriers reported experiencing neck pain related to the weight. Head-carrying was a preferred mode of transport over carrying things by hand only in areas where the terrain was especially difficult.
The research team is currently studying whether head-carrying may lead to long-term damage to the neck.
