Hand-Washing: You’re Still Not Doing It Right
By Felicia Vance
The next time you reach out to shake someone’s hand, consider this finding: A recent study of hand-washing habits found only 5 percent of people who used the restroom scrubbed long enough to kill germs that can cause infections.
Thirty-three percent didn’t use soap, and 10 percent didn’t wash their hands at all, according to the study, based on Michigan State University researchers’ observations of more than 3,700 people in a college town’s public restrooms.
“These findings were surprising to us because past research suggested that proper hand washing is occurring at a much higher rate,” lead investigator Carl Borchgrevink, an associate professor of hospitality business, said in a university news release.
Among the other findings:
- Men were less likely than women to clean their hands. Fifteen percent of men and 7 percent of women didn’t wash their hands at all.
- People were less likely to wash their hands if the sink was dirty.
- People were more likely to wash their hands earlier in the day.
Hand washing is the single most effective thing a person can do to reduce the spread of infectious diseases, according to the U.S. Centers for Disease Control and Prevention. Failure to sufficiently wash hands contributes to nearly 50 percent of all foodborne illness outbreaks, the agency says.
It takes 15 to 20 seconds of vigorous hand washing with soap and water to effectively kill germs, the CDC says, but people only wash their hands for an average of about 6 seconds, according to the study, published recently in the Journal of Environmental Health.
