The "fist bump"—the greeting used by U.S. presidents, sports stars and rappers—has been given a clean bill of health, according to university scientists who released new research Monday showing that it could be more hygienic than the formal and business-like handshake.
The transfer of germs via fist bumping is 90 percent less than a handshake, according to a new report by Aberystwyth University in the U.K. The same research said that a "high-five" could reduce germ transfer by over half.
"People rarely think about the health implications of shaking hands. If the general public could be encouraged to fist bump, there is genuine potential to reduce the spread of infectious diseases," Dave Whitworth, a senior lecturer at Aberystwyth University, said in the report on Monday.
Whitworth and Ph.D. student Sara Mela carried out the study to promote cleanliness in the workplace and the results have been published in the August edition of the American Journal of Infection Control.
