4. Little knowledge about children's life in autumn
Autumn health care
First, strengthen nutrition autumn has come, the weather has turned cold, the interference of summer has ceased to exist, the body has gradually returned to a good state of operation, and appetite and digestive function have been automatically adjusted to the best level. This is a godsend opportunity to make up for the loss in summer. It is necessary to strengthen the nutrition supply and add "oil" to the growth of children. Meat, eggs and milk are indispensable, and fruits and vegetables should also be increased to achieve a reasonable mix of staple food and non-staple food, vegetarian food, coarse and fine, and lean.
Second, timely pest control experts believe that the effect of pest control in autumn is the best. Judging from the life history of ascaris lumbricoides, although children can be infected with eggs all year round, they have the most opportunities in summer. If you suck your fingers, the eggs will enter the body, and after a period of evolution, they will eventually become insects and settle in the small intestine. It's autumn now. At this time, taking pesticides (such as enterotoxin) can be caught in the net, leaving no future trouble.
Third, prevent diarrhea. Babies are most prone to diarrhea in summer. After the autumn, the incidence of diarrhea showed a downward trend, but the heart of prevention must not be slack. Because a microorganism called rotavirus is ready to move, it often attacks children's digestive tract in September or 10 and causes diarrhea, which is called "autumn diarrhea". To this end, parents should help their children grasp the following points: First, block the entrance. Specific measures include paying attention to food hygiene, not eating cold food, boiling and disinfecting toys and utensils regularly, and washing the mother with warm water before feeding the baby. At the same time, we should do a good job in environmental sanitation and eliminate flies and other carriers that spread viruses and germs. In addition, the sick children were immediately treated in isolation, and the excreta was handled well. Healthy children should avoid contact with sick children.
The dry climate in autumn can easily lead to yin deficiency and body fluid loss, such as dry skin and body fluid loss. At the same time, dryness can hurt the lungs, causing symptoms such as dry cough, lack of phlegm or lack of phlegm, dry throat pain, dyspnea, wheezing, chest pain, and even damage the lung collaterals, leading to epistaxis and blood in phlegm.
Because the child's skin is delicate, the breathing frequency is high, and the kidney's concentration function of urine is poor, more water will be lost through the skin, lungs and kidneys. Autumn dryness will be more common in autumn if drinking water and diet are not properly adjusted.
Children's autumn dryness is characterized by nasal congestion, dry mouth, paroxysmal cough and even fever, and a series of symptoms similar to upper respiratory tract infection. But there should be no symptoms such as fever and cough.
Only some dry throat, chapped lips, dry nose, bleeding, dry stool and so on. It is also called "infantile dryness" in medicine.
The key to prevent Sjogren's syndrome in children is to replenish water and eat more fruits with high water content, such as pears, grapes and persimmons. And drink more boiled water or light tea, soy milk, milk and other drinks. Try to eat less salty, too sweet or barbecue food, so as not to cause further exhaustion of vaginal fluid and body fluid, which will only lead to excessive internal heat and dryness.
The living environment should maintain proper humidity. If you feel dry indoors, you can put a basin of water in the bedroom or sprinkle water on the floor appropriately. In addition, let children develop the habit of going to bed early and getting up early, and work and rest regularly, and can't over-entertain or stay up late.
