Remember how Sheldon Cooper gave us all a reason to avoid hand-dryers until the end of time? Turns out, science does indeed have his back.
In results published in the journal Applied and Environmental Microbiology (via CNBC), they found the plates blasted with air carried 18-60 colonies of bacteria on average, whereas exposure to regular bathroom air saw less than one colony on average.
The authors of the study said: ‘These results indicate that many kinds of bacteria, including potential pathogens and spores, can be deposited on hands exposed to bathroom hand dryers, and that spores could be dispersed throughout buildings and deposited on hands by hand dryers.’
