Studies find that a jet air dryer spreads 1,300 times more germs than paper towels. 😯
There’s a chill in the air, tree branches are bare, and the holidays have come and gone. It can mean only one thing: Cold and flu season has officially arrived.
Fortunately, you can take some steps that really safeguard against germs. But others you may have heard of don't work as well, or at all. Here, two germ experts weigh in on which ones are worth it and a couple that aren't.“Hand sanitizers have gotten better in recent years,” explains Charles Gerba, PhD, a germ expert and environmental biologist at the University of Arizona. Look for one that contains 60% alcohol. That's the amount needed to kill germs.
You don’t have to overdo it, Gerba says. Use it once or twice during a typical day, as well as after using public transportation, when you get home, or before you eat .This isn’t a free pass to skip the sink. Hand washing, especially after using the restroom or before you eat, is still crucial for protecting yourself from cold and flu germs. But you may not need to lather up after every handshake when hand sanitizer kills germs just as well.
If it gives you peace of mind, go for it, but that thin piece of paper isn’t going to do much good, since fluid can go right through it, says Philip Tierno, PhD, microbiologist and clinical professor of pathology at New York University. But chances are good you’re not going to come in contact with anything that can infect you, he says.The ground-floor button, which everyone touches, can get especially grimy, Gerba says.Explain that you’re not being rude; you’re protecting your health.
