Decades ago, almost everyone had bloodthirsty parasites. No matter men, women and children, they can't escape his clutches, and they especially like to hide in people's hair. In order to stay away from them, many people shaved off their precious hair and became bald. So after 7080, many people shaved their hair in a few childhood photos. This nasty parasite is lice, which is a very strong memory of many people's childhood. In those days, lice were everywhere, but now they are rarely seen. He seems to have vanished into thin air. Why?

Lice are mainly divided into three types: body lice, head lice and crabs, which are distributed in different parts of the human body. Head lice are the most common and widespread. Scorpions are lice eggs, also called lice eggs. It is mainly milky white with transparent follicles on the outer layer, and its body size is only 1/3 of sesame. The body surface secretes a special mucus, which adheres tightly to the upper half inch and one inch of the hair root. Lice and Polygonum cuspidatum are mainly parasitic on human body and feed on human blood. They not only suck human blood, but also make people feel itchy and uneasy. When people scratch with their hands, it will cause skin damage, cause other skin diseases, and even infect many people with various diseases because of its heredity. The most infectious pathogen is relapsing fever, which can lead to periodic high fever, systemic pain and other symptoms.

Lice, an animal, had seriously affected people's lives at that time, so everyone tried their best to eliminate it. For example, use a special comb to comb the lice and lice off your head. But this method has little effect, because their reproductive ability is as strong as their transmission ability. Each female louse can lay 300 to 400 eggs in just one month, and these eggs can feed on their own when they evolve into scorpions. So everyone began to use various devious methods to remove lice on the U-turn, such as soaking the head with white wine, washing the hair with white vinegar, drawing on the body with chalk soaked in drugs, and even using five dichlorvos. These methods did not clean up the lion, and people were almost cleaned up. But this kind of lion, which was very hard to find decades ago, is now rare. Is it because it disappeared completely in some way?

In fact, lice and scorpions used to run wild. This is because people's economic conditions were not good at that time, which led to poor sanitary conditions. Many people take a long bath and can't change their clothes several times. In addition, there were not so many chemical products before, let alone any chemical pollution. Lice are very active in nature. When people go to work in farmland, it is inevitable to bring some home, and at that time there were no chemical bath products, such as soap, shower gel and shampoo, which did great harm to lice. Now these items can not only clean the stains on the body, but also have various sterilization functions. In addition, with the improvement of living conditions, almost everyone takes a bath and changes clothes every day, which is also very hygienic. Lice can't start with us, but now lions have not completely disappeared in our lives, and there will still be some areas where lice can be used.

Don't panic because lice appear on yourself or your children. Iron clothes with hot water first, and it's best to disinfect them yourself once. Then go to the drugstore to buy a shampoo that can get rid of lice. After washing your hair several times, there will be no more lions on your head. Only by paying more attention to hygiene at ordinary times can lice completely disappear from our lives. Do you still know those ways to get rid of lice?
