the sun has just risen, and it shines on a ranch in Mongolia.
Bayar, a little boy living in a Mongolia bag, is still asleep. The parents went out to work early in the morning, accompanied by a big rooster. I saw the big cock jumped into bed, and then less than a year old Bayar slowly opened his eyes. He stared at the endless passenger station at the head of the bed and fluttered his wings.
the same rays of sunlight skim over an aboriginal tribe in Namibia, Africa. A few months old, from the morning, he appeared with his mother on a wasteland. While the adults are doing their work, the little ones are crawling up and down, sometimes playing with their brothers and sisters. Sometimes she picked up a dry bone from the dirt pile and chew it up with relish. The morning of
Losangeles and Tokyo is equally sunny. Soon after birth, Hardy was sitting in a special baby carriage, covered with dust gauze and ready to go outing with his parents. Zhizaki Masako went to the early teaching lesson with her mother. In a classroom, many children together do exercises and play games with their teachers.
this is a clip from the documentary "sunshine baby". The film records four babies living in different regions, starting from birth.
in addition to being attracted by the lovely actions of children, I was surprised to find that the sanitary conditions of their living environment were so different. Bayar and pen's growth environment is close to nature, but has more opportunities to contact bacteria. In particular, Peng Ni Qiao, the main place of his daily activities is full of dusty land, thirsty to drink water in a dirty ditch. Hadi and chicazi, who live in big cities, even go out to avoid the sun.
according to WHO data, children under 10 million and 5 years of age die each year. Pneumonia, diarrhea and malaria are the main reasons. In Namibia, about 42 children per 1000 children died before the age of 5 and 41 in Mongolia, while in the United States and Japan, only 8 and 4 were in the United States and Japan, a survey showed.
this has something to do with children's living environment. For example, every 30 seconds, an African child died of malaria. The solution was only to set up an insecticide treated mosquito net.
on the other hand, there are data showing that children in the city are at a higher risk of certain diseases, such as allergies, asthma, and autoimmune diseases such as type I diabetes, multiple sclerosis and inflammatory bowel disease, compared with the babies in the rural areas of the less developed countries, although the living conditions are superior.
according to the "hygiene hypothesis" theory put forward in the 90s of last century, these contradictions are not surprising. According to this theory, proper exposure to bacteria and viruses during childhood can help the body fight allergic reactions. If there is no such contact, the immune system of the human body may be in disorder, causing human mechanism problems and immune diseases.
there is a saying that exposure to a certain amount of bacteria and dust at the beginning of life will activate the body's immune system and prepare for future threats. In 2010, a report from the Journal of the Royal Society said a long-term survey of 1700 Filipinos from birth to 21 year old showed that those who had grown up in the living environment of chickens, ducks, pigs and dogs have had a few dysentery when they were young, and the C reaction to egg white in the adult body was lower. C reactive protein is an inflammatory marker and is associated with cardiovascular disease.
scientists also counted the incidence of hay fever and eczema, and found that many brothers and sisters were less likely to get these two kinds of diseases. According to his judgment, children from large families have many opportunities to contact each other and have more opportunities for cross infection. Their immune system has been trained to identify real enemies.
some experts even believe that if they are sent to the nursery after a few weeks of birth, the risk of leukemia will be low. In nurseries, infants cough, drool, suck their fingers, and the immune system they are forming is placed in an environment containing various bacteria. In this way, the immune system is always active and the body's resistance is enhanced. According to this statement, perhaps minibus and Xiaopeng will be healthier. The former babysitter has a goat besides the big cock. When he came home like a clay figurine on the prairie, his mother would wash him in a small basin. At this time, the thirsty goat would stretch out his head and take a drink in the bath water, and then walk away as if nothing happened.
may add a sentence: "be clean, live without disease!"
