What’s the most hygienic way to dry your hands?
These questions are even more critical now than ever before.
According to the article posted by Harward Medical School, using hand dryer for 30 seconds after washing your hands may place, on average, from 18-60 colonies of bacteria on your hands.
This study was done by the University of Connecticut and Quinnipiac University.
The conclusion was that most of the bacterial splatter from the hand dryers had come from the bathroom air.
How did it get there? Apparently, every time one flushes a lidless toilet, it puts out a fine mist of fecal cloud into the air. Bacteria are naturally attracted to heat while the hand dryer circulates and pulls it from the bathroom air, condenses it, and puts it right back at your newly washed hands.
After washing our hands for a minimum of 20 secs, as recommended, and drying them with the hand dryer, we think we did our part, and our hands are now sterile. We then go on with our lives casually touching our phones/face/eyes/hair and handshaking with friends and family, thus unknowingly and unintentionally becoming the ones spreading germs and bacteria.
So what’s the most hygienic way to dry your hands?
Paper towels are still the answer. Due to the friction, they help with removing the leftover bacteria from your hands after washing them.
I have seen some travelers even brushing their teeth and/or shaving in public bathrooms. If you are one of those frequent travelers, then you may want to drop the habit
