Handshakes – firm or otherwise – transfer about 10 times more germs from hand-to-hand than a ‘fist-bump’. Eeuw.
This is actually a serious piece of research that was published in the August issue of the American Journal of Infection Control.
In a test that sounds like something out of the Bones or CSI labs, a researcher dipped one gloved hand into a container full of E.coli bacteria (a tame variety), then shook hands, high-fived and fist-bumped the clean, glove-covered hand of another researcher.
This Is What They Found
The dirtiest exchange of all turned out to be the handshake, spreading twice as much bacteria as a high-five and about 10 times more than a fist bump! The researchers ran the test again, but this time, they used paint, and with the same result.
Whether you shake, high-five or fist-bump, remember that washing your hands is the most effective way to keep yourself cold and flu-free.
