Washing Hands In Cold Water Works As Well
As Hot Against Germs
This is the study that gets you out of hot water.
When washing hands in a public restroom (when you visit a public restroom, it is often written that “please wash your hands”) But heres what! you no longer have to switch the tap to scalding to be assured your hands are germ-free.
Scientists at Rutgers have found that cold water for at least 10 seconds — with soap of course — is just as effective at washing off bacteria as hot water.
In their experiment, 21 participants got their hands dipped in harmless bacteria over a six month period and told to wash their hands in 60-, 79-, and 100-degree Fahrenheit temperature water. The researchers found that the temperature didn’t matter — just plain ol’ soap and water does the trick.
The study also found that people who regularly used lotion on their hands had fewer bacteria after washing than those who didn’t, this is probably because moisturizing can help repair dry and damaged skin that’s more difficult to clean.
Donald Shaffner, one of the study authors, said that this could have effects not just on personal hygiene, but also energy consumption. “Cold water saves more energy than warm or hot water,” he said in a statement. Currently, FDA regulations require hand washing temperature must be 100 degrees. But with this study the, it can be said that the time has come to change the rule!
