Jet air hand dryers might be a quick and easy way to dry off, but scientists say they might actually be spreading germs around public restrooms. Researchers say the problem is that jet dryers blow bacteria around, where it can end up contaminating other areas of the bathroom like sinks.
In fact, a recent study found that bathrooms with jet dryers contained up to five times more bacteria than bathrooms with paper towels. That can be a major problem for people with weakened immune systems, which is why scientists are advising hospitals to move away from jet dryers.
