Living environment is too clean and harmful to human health

Living environment is too clean and harmful to human health

We have been educated since childhood to be a good boy who is clean and clean, but as we grow older, the rules of the world have changed again.

Many people love clean people. In an overly neat environment, they are easy to breed diseases.

And some people who are less fierce about the environment and their own requirements can better adapt to it. What is going on?

Research tells us that sometimes “dirty” will make you healthier.

  In a sense, cleaning is healthy and hygiene is clean.

  The latest research shows that the fragile makes the creature overcome the resistance.

  Blessed are those who are lazy and unruly.

In the face of criticism from the cleansing elements, you can be justified and dirty, and healthier.

  This is scientifically based.

The study of pigs by Denise Kelly, a disability immunologist at the University of Aberdeen in the United Kingdom, found that there is a direct relationship between a spacious living environment, immune health and gene expression.

If piglets grow freely outdoors, they will get beneficial bacteria and get along with bacteria and viruses in the future to get the best immunity.

  When the free pig researchers selected 54 piglets, they were randomly divided into three groups, living together outdoors, grouped in captivity, and another group feeding them antibiotics every day to live in an environment that was completely replaced with the outside.in.

The researchers then killed the piglets at 5 days (neonatal period), 28 days (weaning period) and 56 days (near maturity) to study their own tissues and feces.

  These three groups of pigs have different lifestyles and their appearances are also different images.

The pigs that live freely outside are exposed to nature and roll in the mud, which looks dirty and ugly.

The post-primary pigs that are housed indoors are white and fat.

The difference in appearance will of course reflect the difference in the internal conditions of the body.

Contrary to the traditional notion that cleanliness is health, the tiny piglets that grow freely outdoors are better at immunity.

  The researchers found that 90% of the bacteria in outdoor pigs are thick-walled, most of which are lactobacilli.

The bacteria are good for health, and they bring piglets with the ability to inhibit pathogenic bacteria such as E. coli and Salmonella.

About to say, in the pigs that are housed in the house and the antibiotics are completely isolated from the outside, the thick-walled bacteria are less than 70% and 50%, respectively.

At the same time, the proportion of bacteria from the genus Lactobacillus is also small.

Therefore, the type of bacteria in the body can be ground, and the pigs that grow freely outdoors have higher immunity and stronger disease resistance.

  As such, differences in the microbial population within the piglet also affect gene expression associated with the pig’s immune system.

Piglets growing in an isolated environment express more genes involved in infections and plasma synthesis, but pigs that grow freely outdoors have more gene expression associated with immune T cells.

Although it is difficult to judge the mechanism of action of inflammatory immune response and cholesterol gene expression and whether it is beneficial to the organism, the excessive expression of genes associated with T cells indicates an enhanced immunity to the organism.Since cells are the main immune cells of mammals including humans, cellular immune functions are performed.

Therefore, if this immune mechanism of pigs is applied to humans, intervention in bacteria during early childhood may reduce future allergies and other autoimmune diseases.

  For a study by researchers at the University of Aberdeen, Glenn Gibson, a food microbiologist at the University of Reading in the United Kingdom, sees this as a direct argument for a relationship between living environment and immune response, and previous research.Just indirect inference.

This shows that the immune response is indeed linked to microorganisms in the body.

At the same time, researchers at the University of Aberdeen are now taking a step forward, as this study shows that gene expression is consistent with immune response.

However, since the research was carried out on pigs, it cannot be said that the same diffraction can be caused to humans.

  Too much attention will lead to a civilized disease. In fact, there have been many studies that have proved that some dirty environments can enhance the performance of immunity.

For example, in the same situation where the stubborn mice in the gutters and farms live in a comfortable sterile laboratory, the former’s immune system is healthier and less susceptible to sensitivity and disease.

An allergic disease study conducted by Arizona researchers in 1,246 children showed that if a baby is often in contact with other children during the first 6 months of life, the probability of illness can be greatly reduced.

Moreover, the proportion of babies who are not in contact with other children and who are rarely exposed to other children may be a small part of the babies who are cared for by nurses or caregivers.

  There are more research results to illustrate the problem.

In today’s society, high blood pressure, hay fever and allergic dermatitis are known as civilized diseases, which are growing at speed in Japan and West Germany.

The comparison of history is very interesting.Unlike West Germany, the incidence of such civilizations in East Germany is much lower than in West Germany.

After investigation, it was found that the sanitary conditions in East Germany were not as good as those in the former West Germany, and the environmental pollution was higher than that in West Germany. Therefore, the children in East Germany had high rates of parasites such as aphids, and as a result, their immunoglobulin E values also followed.It is elevated, thereby inhibiting diseases such as hypertension, hay fever, and allergic dermatitis.

  Moreover, the results from animal experiments are even more alarming.

White rats infected with two aphids and not infected with aphids were infected with dysentery. All of the former survived and all died.

In other words, parasites can only prevent organisms from allergies and provide the ability to fight against acute protozoa.

These conditions indicate that people need to be in full contact with nature, not to close themselves or to kill microorganisms or parasites because of pathogenic bacteria and parasites, because they are essential to enhance our own immunity.

  However, the problem now is that if the concept of clean and dirty is aimed at people, parents and educators realize that they have different requirements for children.

For example, rural children and urban children have different requirements for cleaning because of the different opportunities and time of contact with nature.

Rural children will be dirty, the children of the city will be clean, but the immunity of the former is definitely stronger than one.

Therefore, scientists and educators need to establish a child’s natural contact with the line, and accept the idea that the child is slightly dirty may be better, because it will help to enhance their natural immunity.
