A new study published in The Journal of Environmental Health found that after using the bathroom, many of us aren’t washing our hands properly – or even at all!
Researchers discreetly watched 3,749 people, 60 percent of them women, after they used public restrooms in a Michigan college town. In total, 10.3 percent did not wash their hands at all, and 22.8 percent used no soap. The rest of those observed did use soap, but only 5.3 percent washed for longer than 15 seconds, soap or no soap.
According to the Centers for Disease Control and Prevention (CDC), proper washing means rubbing vigorously with soap and water for at least 20 seconds.
Men did worse than women — almost 15 percent of them did not wash at all, compared with 7.1 percent of women. Of note, people were more likely to wash their hands properly if there were motion-detection faucets, a clean sink or a sign encouraging the practice. Researchers also pointed out that having even discreet observers probably increased the likelihood of hand washing.
