Do you take your shoes off when you enter the house? If the answer is negative, you risk your health.

There are many reasons why it is necessary to stop wearing shoes in your house.

Bacteria

Some bacteria are good for us, and there’s some harm. A study at the University of Arizona examined the microbes on their shoes and discovered that on them has about 421,000 bacteria on average and in nine different strains. Among the harmful species was and E. coli, which causes intestinal infections, diarrhea and, in rare cases, meningitis.

Klebsiella pneumoniae, which can cause urinary tract infections, and Serratia ficaria which causes respiratory inflammation is also found.

“Street trample different areas, bird and dog faeces and germs from the floor of public toilets,” explains Kelly Reynolds, a microbiologist and professor at the University of Arizona.

“If you wear the same shoes in the house, that you wear outside, the bacteria will settle under your house and continue to breed.”

Toxins

Another potential problem are the toxins, because the chemicals that treat grassy areas can be easily entered into the house.

A study conducted by Baylor University showed that people who live near paved roads, whose construction is used and tar, often suffer from cancer. Toxins are found in the dust flying all around us and most are attached to the shoes while we walk.

Filth

“Filth itself is not harmful,” says Dr. Reynolds, but adds that you should reduce it to a minimum, especially if you have a small child in the house. “Children often put fingers or toys in their mouths and this is the reason why you should maintain the floors and other surfaces maximum clean.”
