Putting down the toothpaste and the wound is simply worse. According to the experience of the older generation, toothpaste, soy sauce and vegetable oil should be applied when scalded, but in fact these are unscientific. The mint in toothpaste may temporarily cool the wound, but it is easy to cause bacterial growth and wound infection. Similarly, applying soy sauce and vegetable oil after scalding can not only reduce the injury, but also stimulate the wound and increase the chance of infection.
Constipation is a trivial matter, and a banana can solve it.
Cooked bananas can really relax the bowels, but raw bananas are counterproductive. Cooked bananas are rich in dietary fiber, which can increase the volume of feces and promote intestinal peristalsis. At the same time, the sugar content of banana is above 15%, and it contains a lot of water-soluble plant fiber, which can cause hyperosmotic gastrointestinal fluid secretion, thus absorbing water to solid parts, making feces soft and easy to discharge. However, if it is an immature raw banana, it contains more tannic acid, which will inhibit the secretion of gastrointestinal fluid and gastrointestinal peristalsis. If you eat too much, it will cause constipation or aggravate constipation.
If you have a fever, wrap yourself in the quilt and sleep. Just cover yourself with sweat.
Sweating is the result of fever, not the cause of fever. I believe many people will use "covering sweat" to reduce fever, but in fact this method is not scientific. Fever is a struggle between the immune system and disease. When the invading substance was destroyed by the immune army, all the functions of the human body returned to normal, and the elevated body temperature gradually dropped to normal. At this time, sweating occurs, and the body heat is taken away through the evaporation of sweat, and the body temperature returns to normal. So sweating is the result of fever, not the cause. The method of "covering sweat" is not desirable, especially for Xiao Baobao, which may lead to a series of serious consequences such as "covering heat syndrome" and shock. ?
04, look up when nosebleeds.
When the weather is dry in winter, some children will have symptoms of getting angry and nosebleeds. When a child has a nosebleed, many parents will make the child look up and even raise his hand, claiming that "the nosebleed can be suppressed". Medical experts say that raising your head when nosebleeds can not only prevent nosebleeds from flowing out, but also make blood flow to the back of nasal cavity, mouth, and even trachea and lungs. Once nosebleeds flow into the trachea or lungs, it may lead to bronchitis, pneumonia, and even dyspnea, which is directly life-threatening!
05, cold smoked vinegar
When I was sick and caught a cold when I was a child, the smell of smoked vinegar filled my home. But smoked vinegar can't make a cold get better faster at all! Media experiments show that although a certain concentration of acetic acid has the function of disinfection and sterilization, it is difficult to achieve the effect of sterilization and disease prevention with smoked vinegar because of the low concentration of acetic acid in vinegar. Moreover, when the concentration of vinegar is too high and the time is too long, it will also stimulate the respiratory tract and cause bronchitis, emphysema, asthma and other diseases.
Also, cutting eyelashes will make them longer, pinching your nose will make your nose stiff, and trimming your eyebrows will make your eyebrows thicker. It's all unreliable old methods.
