Now the child is more and more prone to allergies, not moving on the cold sneezing, body rashes, many parents are puzzled, when we were in poor conditions are very skinny, why now the child is in good condition but more and more delicate? Don’t play with the sand, don’t touch the dogs and cats …… now children “too clean”! In the public place to see parents with four or five-year-old children, often hear “don’t move!” “Don’t touch!” “Dirty!” …… such reprimands. In an urban family, from the day the baby is born, the whole family starts the big project of washing, boiling and sterilizing. Clothes are washed every day and diapers are changed all the time. The bottles are the most frequently cleaned, and every time they are eaten, they are boiled in a pot. When children are older and can run and play, there are a lot of “rules and regulations” that bind them: “Don’t play in the sand, don’t touch cats and dogs, and don’t roll on the grass”, in short, the word “don’t” is always on parents’ lips. In short, the word “don’t” is always on parents’ lips. Allergies are a reaction of the body’s immune system to external substances, including pollen and animal hair. If your immune system is rarely exposed to these things, then when it is, the immune system is out of whack. From antiseptic soaps to hand sanitizers to the widespread use of air-insulating gaskets on windows and doors, the modern urban home is becoming more and more of a “mecca” for cleanliness and hygiene. The body’s immune system is being “protected” by more and more artificial means, including vaccines and antibiotics. “Our push for clean lifestyles has resulted in an immune system that is less militant and more prone to allergies.” said a physician specializing in pediatric allergies at the University of Michigan Health. The immune system needs “stimulation” may be appropriate for the child “free-range” After the birth of the children, if they can continue to contact the external environment of some of the dirty things, their immune system is a challenge, in the process of accepting these challenges, the immune system continues to strengthen, so that even if some bacteria encountered later on, the immune system is not a challenge. In the process of accepting these challenges, the immune system is constantly strengthened, so that even if they encounter some bacteria, viruses and other undesirable elements in the future, they will also be “not alarmed”, not to the onset of disease. If you grow up living in a very clean environment, the body’s immune system due to “not much seen in the world”, a little bit of small stimuli will let them make a strong reaction, that is, in the body embodied in the allergy symptoms. The more “sophisticated” the family, the higher the incidence of allergic diseases. Clinical statistics show that the incidence of allergic rhinitis, asthma and other allergic diseases is on the rise in major cities such as Beijing and Shanghai. Parents pay too much attention to hygiene, so that children have no immunity at all to their surroundings.” Since the child can not live in a vacuum, the small environment at home to get even cleaner, the child is inevitably exposed to the outside world germs everywhere in the environment, so it may be worth letting go a little bit, learn from rural parents, the child to take the appropriate “free-range” policy, the child may be healthier, stronger. Expert Opinion: The right and proper “free-range” Let the child pay attention to hygiene is of course very necessary, but to grasp a good degree, do not reprimand the child this can not touch, that can not play. Playing in the sand, scratching bugs or rolling in the grass with the dog is fine. If your child comes home with a sweaty, muddy face, just wash it off. Pay attention to washing hands before and after meals, don’t let your child eat unclean food, as long as you pay attention to these basic hygiene matters, your child won’t have big problems. In addition, it is important to maintain good indoor ventilation, often open the window ventilation can be a lot of harmful germs blowing out, and air circulation of the room is not conducive to the growth of dust mites, to help prevent the occurrence of allergies. As for disinfecting antibacterial or disinfecting products, if there is no patient in the family, it is better to use less, often use these products, will only make the child’s resistance become weaker.
