Why Most Indians Prefer NOT Wearing Chappals Inside The House

There are some rules that have been made for us right since our childhood. Just like you can’t wear whatever you wish to school or can’t bunk office at your convenience,  you cannot wear your shoes inside the house. While there maybe a few exceptions, most Indians have a habit of removing shoes outside the house.

And while most of us do it for hygienic reasons, we have finally got the answer to WHY we do so.


According to a study by the University of Arizona, there are almost 421,000 bacteria that are found on one’s shoes. Out of all the shoes that were examined, 96% of them had coliforms, which is a bacterial indicator of the level of sanitation of foods and water which is also said to have been found in faeces of humans and warm-blooded animals.

Apart from that, 27% of the shoes had seven different kinds of bacteria along wit E.coil, which included Klebsiella pneumonia, a bacteria responsible for causing urinary tract infections, and Serratia ficaria, a bacteria responsible for causing respiratory infections.

“The common occurrence (96%) of coliform and E. coli bacteria on the outside of the shoes indicates frequent contact with fecal material, which most likely originates from floors in public restrooms or contact with animal fecal material outdoors. Our study also indicated that bacteria can be tracked by shoes over a long distance into your home or personal space after the shoes were contaminated with bacteria,” explained Charles Gerba, a microbiologist at the University of Arizona.

You’ll be shocked to know that as per the research, public restrooms floors have an estimated 2 million bacteria per square inch, and an average toilet seat has about 50 square inches. Now imagine getting all of those into your house through your footwear?

Kelly Reynolds, yet another microbiologist and professor at the University of Arizona said, “We walk through things like bird droppings, dog waste and germs on public restroom floors, all of which are sources of E. coli. Think about rain water in the street. It can have gasoline in it and chemicals, and those get on your shoes and can be brought into your home.” There is no chance of getting rid of the bacteria and dirt present in the air. However, the only way to get least affected by the germs on your footwear is to wash your footwear in the washing machine. Cleaning your shoes in the washing machine kills the presence of germs almost by 90%. You must also clean your floor and carpets regularly to keep yourself away from any illness.
