Warm hand dryers increase bacteria by 254%
Warm air hand dryers cause an average 254% increase in the number of bacteria on the palms of people’s hands as well as contaminating the surrounding area, according to a recent study by University of Westminster in London.
The study also showed that on average, paper towels reduce bacteria on the hands by 77%.
The University’s School of Biosciences conducted a study of three different hand drying methods; paper towels, regular warm air dryers and the new generation “jet” air dryers.
Each drying option produced radically different results with warm air hand dryers causing an alarming increase in the amount of bacteria found on palms and finger pads.
