Here’s how soap, sanitizer and warm water is protecting you from COVID-19
Washing hands can kill nasty bacteria and potentially lethal viruses that have plagued humans for centuries -- including influenza and several other coronaviruses.
If you are tired of washing your hands for 20 seconds each time and your fingers have started to prune or feel like sandpaper, please do not stop. The entire world is counting on you to help prevent the spread of Covid-19, the deadly new disease.
Washing hands can kill nasty bacteria and potentially lethal viruses that have plagued humans for centuries — including influenza and several other coronaviruses.
Water and washing your hands are necessary because the combination produces more soap bubbles, which interrupt the chemical bonds that allow viruses, bacteria, and other germs to stick to surfaces.
Now, when you wash your hands, all the germs that have been hurt, trapped, or killed by soap molecules are washed away.
You often hear that wash your hands with warm water, but why?
A chemist, Bill Wuest, an associate professor at Emory University who studies disinfectants, told a source, “Warm water with soap creates a much better foam and more bubbles. These bubbles are a sign that the soap is trying to compress the dirt (bacteria and viruses) in them.”
A professor of preventative medicine and infectious disease at Vanderbilt University School of Medicine in Nashville, Dr. William Schaffner, said, “Alcohol-based hand sanitizers could be as useful as soap if they are correctly used. The sanitizers need to have at least 60 percent of alcohol in them. It is the alcohol that kills the virus.”
Alcohol is quite effective at killing germs, but it does not wash away stuff. If somebody just sneezed into their hand, and their side is covered with phlegm, they would have to use a lot of alcohol to inactivate that bacteria or virus. Therefore, if somebody’s hands are grossly contaminated, soap and water are better.
So next, time, when you wash your hands, take pride in all those foamy bubbles you are creating and enjoy the pleasure of imagining those tiny, dead creatures circling the drain.
