A study published in the Journal of Environmental Health found that only 5% of consumers wash their hands correctly. Scientists trained 12 college students in the field of data collection. They then observed 3,749 people washing their hands in public toilets.
The observers found that 15% of the men and 7% of women didn’t wash their hands at all. Only 50% of men and 78% of women used soap. People were less likely to wash their hands if the sink looked dirty, and more likely if a sign telling people that hand washing is a good idea was hanging above the sink. And for some reason, more people wash their hands during the day than at night.
