Handshake is the least sanitary greeting: Study (Fotolia)


 

If you're looking for a less germy greeting, go for a fist bump over a handshake or high five, new research shows.

The researchers, from Aberystwyth University in the United Kingdom, state the fist bump still provides the culturally expected hand contact but without spreading as much bacteria.

To come to the results, one researcher wore a sterilized glove and the other wore a glove that had been contaminated with germs and dried. The researchers then exchanged a handshake, high five or first bump for varying lengths of time and the gloves were analyzed for exchanged germs.

A handshake shared twice as much bacteria as a high five, and significantly less bacteria was transmitted with a fist bump. The longer the greeting, the more germs were shared.

"It is unlikely that a no-contact greeting could supplant the handshake; however, for the sake of improving public health, we encourage further adoption of the fist bump as a simple, free and more hygienic alternative to the handshake," author David Whitworth said.
