Amish minorities in the United States

Amish is a special minority community in the United States. People in this community almost do not use modern machinery and technology. Travel by horse-drawn carriage and maintain the same agricultural lifestyle as ancestors hundreds of years ago.

Families here often keep pets in the house. Children are exposed to nature from a young age. They often play with mud, contact with bacteria, fungi and farm waste. However, the rate of children with asthma, allergies and many infectious diseases is surprisingly low.

This is in stark contrast to the common Western concept of raising children. According to many experts, the reason may be because the living environment is too clean. The body is not acquainted with the causative agent. Leads to reduced immunity.

2. Hygienic theory

To explain the phenomenon, some experts have introduced hygiene theory. This is a hypothesis about medicine. Hygienic theory suggests that young people should be exposed to bacteria, including pathogenic bacteria and beneficial bacteria (such as intestinal bacteria), and parasites.

When this defects, the child’s immune system will not develop completely. Increasing the rate of infection and sensitization in children.

Some evidence shows that autism also has an immune cause. At the same time, it is the cause of the incidence of leukemia in adolescents in developed countries. Many families do not have pets in their homes.

3. Domestic pet farming affects the immune system

Domestic pet farming affects the immune system

When bacteria enter the body, the immune system will automatically classify as harmful or harmless. Pregnant women with cats and dogs will often come in contact with their fur, stains, and body fluids. This is confirmed to affect fetal immunity.

Healthy cells in the human body contain a special protein. By identifying this protein, white blood cells can differentiate normal cells and bacteria. If it is a pathogenic bacterium, leukocytes will destroy and save information. The next time you meet again, the immune system will quickly resist the disease.

Now science still does not explain how and how the mechanism affects the young body. But the percentage of children from families who have pets in their home is healthier than those who don’t.

4. Be careful when raising pets

Be careful when raising pets

Although proven to be beneficial, parents need to be cautious when raising pets. Because it is very dangerous if the immune system makes mistakes or cannot distinguish bacteria. The body will have an overreacting or unresponsive reaction.

There have been many cases of anaphylaxis after being stung by a bee. In the past 40 years, allergies and dyspnea due to anaphylactic shock have become popular in the West. The rate of increase is nearly double. Headaches for professionals and parents.

Exposure to pathogens is not synonymous with poor hygiene. Many bacteria and viruses have a strong attack on the immune system. Without protection, children are very vulnerable. There are many deaths from easily preventable diseases.
