According to a new study, bathroom hand dryers spread bacteria in a big way. Researchers found that the dryers are home to up to 60 different colonies of bacteria, and all those germs get blown around the bathroom as soon as someone starts one up.
The safest bet for hand drying is the simple paper towel, which reduces the amount of germs spread around by over 400 percent, when compared to the hand dryer.
