Unexpected truth hidden under your nails

The latest research shows that hand washing cannot be as clean or 99.9% clean as ads.

Hand washing is a great way to prevent the spread of germs. But we can see how good hand washing and hand sanitizing are, doctors or food sellers still have to use gloves during work.

The reason is because hand washing only helps people remove bacteria on their skin, while the bacteria that reside underneath their nails are "inviolable".

Nails and truth . horror

In the middle of the human nail layer and the finger flesh exists a small space called subungual.

By the end of the 1980s, scientists had conducted "dissection" to study what was beneath human fingernails.

And in an experiment in 1988, the trio of scientists from the Department of Dermatology at the University of Pennsylvania (USA) conducted a nail study of 26 volunteers.

The research results show that there is a small space called subungual in the middle of human nail layers and finger flesh. This is the ideal place to "harbor" harmful bacteria for humans. The number is . up to hundreds of thousands of species.

The subungual area is considered to be a suitable place for the collection of bacteria because this place fully converges the elements to help them grow. The nail layer acts as a shield to protect bacteria from external physical impacts, and also helps maintain moisture.

Nails are home to hundreds of thousands of different species of bacteria.

Natural nails are still the best

Some studies also show that bacteria grow and multiply not only in natural nails but also in artificial nails or painted nails. Even the amount of bacteria on these types of nails is much larger than on natural nails.

In 1989, the United States fluttered about a topic, whether it was permitting nurses to apply nail polish before taking care of patients.

Those who wear fake nails also tend to wash their hands over loudspeakers and they themselves don't know.

There are 56 nurses who are invited to experiment, and the results show that the amount of bacteria on their fingernails is much more than the number of nurses to natural nails, including before or after washing hands.

However, only bacteria on their fingertips are more, so this does not mean that nurses can transmit more bacteria to the sick person. This is only true in the case of nurses painting their nails.

According to research from 2002, fake nail wearers also tend to wash their hands over loudspeakers that they themselves don't know, making the amount of bacteria left in their hands relatively large.

False nails contain a large amount of bacteria.

In addition, the nurse's fake nails were also criticized during the early 21st century. False nails contain a large amount of bacteria and can even tear used gloves. once in the hospital.

Each year 2 to 3 million people die from diarrhea, and pathogens can come right from your nails.

Therefore, experts also recommend that we only keep our nails short and clean. In addition to being more careful, you should also prepare a brush to scrub your nails when washing your hands with soap.
