Researchers examined three hand-drying options: |
| • |
Paper towels. |
| • |
Warm air dryers. These are the old fashioned blowers with a nozzle that shoots air downward onto your hands. |
| • |
Jet dryers. These are the newer devices with a slot into which you place your hands. They shoot out air at 300 mph. |
|
|
Scientists at the University of Westminster asked subjects to dip their gloved hands into a solution of a harmless virus, MS2. Then, after giving their hands a quick shake, they tried one of the three drying methods. |
|
Finally, samples were collected from the air and surfaces at different distances from where the drying took place. |
| The verdict? |
| The jet blower is a germ-spewing machine – an erupting Volcano of Germs.
|
| It spread 1,300 times more microbes around the bathroom than paper towels. Some of the virus particles landed 10 feet away. Jet dryers were 60 times germier than regular warm air hand dryers. |
| Researchers concluded that jet dryers not only put the person who is drying their hands at risk... They endanger others in the bathroom at the same time. The scientists said warm air blowers are somewhat better because they push germs towards the floor. Paper towels are the best option because they create little air movement. |
| Viruses blowing around you could result in the flu, a cold, diarrhea... even measles or chickenpox, scientists said. The findings echo those of a 2012 review in the Mayo Clinic Proceedings, which concluded that paper towels remove more bacteria than traditional air dryers. (They didn’t look at jet dryers.) Paper towels create friction and this helps physically remove bacteria, scientists said. |
| In fact, some experts believe this friction removes more microbes than actual washing. |
| The Right Way to Wash Your Hands |
| Handwashing is a crucial defense against contagious disease. But most people aren’t doing it right. Some don’t do it at all. |
| Washing your hands could help prevent the transmission of viruses and other nasty pathogens. But there’s a right way and wrong way to do it. |
| Here’s the right way: |
| • |
Put soap on your hands. Stay away from soaps containing triclosan or labeled “antimicrobial.” They’re linked to hormone problems and liver damage. |
| • |
Turn on the water. Studies show it doesn’t matter if it’s hot or cold. |
| • |
Rub your hands together for 20 seconds. Don’t neglect the back of your hands and between your fingers. |
| • |
Rinse thoroughly. |
| • |
Turn off the faucet using a paper towel or your elbow. |
| • |
Use a paper towel (not the jet dryer!) to dry your hands. |
| • |
As you exit, don’t touch the door with your hands. You’ll undo all your good work. Use a paper towel to turn the knob. Or push open the door with your hip or elbow. |
