Many people in the countryside in the 80s had lice on their bodies, did they not care about hygiene,

In my opinion, the hygiene awareness of rural people in that era was really poor, so there were lice on people's bodies. Lice are still very contagious, and they are not hygienic, so many people get lice.

It is unhygienic. Because at that time, the problem of food and clothing for rural people had not been completely solved, and there were no conditions for bathing at all.

I think it was because of the lack of hygiene, so few people would go to the bath at that time, because the conditions were still quite difficult at that time, and it was necessary to boil hot water, so it was because of hygiene.

This little creature is used to living on people's dirty hair and **. It lives by absorbing human sweat, secretions, body fluids, dust, and other dirty substances. It reproduces quickly, adapts strongly, and is very harmful to human **.

It also secretes lice toxins, which are harmful to human health. Lice are parasites on the body's unclean hair and **.

First of all, lice prefer a dirty living environment the most.

In rural areas in the past, due to economic difficulties, farmers lacked money and could not afford high-grade detergents such as soap and shampoo. Even if they do, they are reluctant to use them. Bathing and shampooing should only be washed with clean water.

For human secretions that are insoluble in water, there is no way to wash them off. As a result, the cleanliness of the human body is poor. This filth has become an ideal environment for lice to parasitize, breed and live.

Secondly, lice do not like a clean and hygienic environment.

Lice like to hide in people's hair and have an ideal place to live. If a person's body is very clean and hygienic, and the dirt secreted daily is removed immediately, the lice will have no food to eat and will lose their living environment. Therefore, the human body pays attention to hygiene and cleans the hair every day, lice will lose their living environment, and lice on the human body will be eliminated naturally.

Thirdly, lice are most afraid of soaps, shampoos, and other detergents.

When people work every day, their bodies secrete a lot of waste products that are excreted from the body. Soaps, soaps, body washes, shampoos, and other cleansers are chemicals that have a lethal killing effect on lice, preventing lice and nits from surviving properly. (3) Laundry detergent must be used for laundry, and laundry detergent is a chlorine-containing substance.

Washing clothes with a certain amount of laundry detergent ingredients can cause lice to lose their living conditions. Therefore, after people regularly use this cleaner, it is now very clean and hygienic, and chemical cleaners have become the scourge of lice, so that lice do not have the conditions to live at all, and of course lice are basically extinct.

Because the standard of living is improving now, everyone is clean now, so there are no lice.

Because now people's cleaning products are more powerful, and they also pay more attention to their own hygiene.

I feel that the quality of life of people has improved, so now it is no longer visible.

Why did people 30 years ago have so many lice on their bodies? The truth makes people sweat.

This should be because people nowadays have requirements for their own cleanliness.

For the post-60s, post-70s, and most post-80s people in rural areas, they should be no strangers to lice. In the countryside at that time, almost everyone, young and old, had lice. Since the main hiding place of lice is in the hair, some parents will shave their children's heads in order to avoid lice bites, and even girls will be treated in this way.

In the past, the vast majority of people in the countryside had lice, because the rural conditions at that time were very difficult, and they did not pay much attention to personal hygiene. This sweat and rain provide relief for bacterial growth, and also create conditions for lice to grow. Add to this the fact that lice are very adaptable, reproduce quickly, and are also transmissible.

As long as one person has lice on his body, almost the whole family will have lice on them.

Lice can be transmitted not only from person to person, but also from animal to human and human traffic. In the past, every household in the countryside raised chickens, ducks, pigs, dogs and other animals, and these animals ran everywhere, and they were full of fleas and lice. These animals are free-range, and they walk around the house every day, and the farmers have very frequent contact with them, so the lice on these animals are also transmitted to the farmers.

After sweating every day, I will take a shower in time, change into clean clothes frequently, and use shower gel, shampoo, etc. to wash, and clothes will also use laundry detergent. Everyone's body is clean and hygienic, and there is no environment for lice to grow, so there is no more.

Don't panic if you have lice on your body, there are some special medicines now, use it to wash your hair, and then wash your clothes again, you can quickly get rid of them. Now the big guy should understand why there are no lice on people now.

Now people's quality of life has improved, and they are also very hygienic, because now people's food and clothing are sterilized, so there are no more lice.

Lice appear on the human body because the environment at that time could not ensure hygiene, and now, ensuring one's own hygiene is the most basic thing, so lice will no longer appear on the body.

This is because people nowadays pay great attention to hygiene, often take baths, and the conditions are getting better and better, so lice are not often seen now.

It is because people have begun to pay attention to personal hygiene, wash and change clothes frequently, and after a long time, they will disappear.

In the 80s of the last century, why did people have so many lice? You never knew the answer.

Why were lice so hard before the 80s**? Before the 80s of the 20th century, lice were common and difficult to **. Why?

This is mainly because lice have a strong ability to reproduce. The life cycle of lice is about 45 days. A female lice can lay 10 eggs per day.

The egg will hatch into a small lice after eight days. Little lice don't need to "learn", but are born to suck blood. The main thing is that the eggs of lice are small, sticky, stuck to people's clothes, hair, and difficult to remove.

So, even if you catch and kill all the lice, after a few days, when the eggs hatch, you will still have lice. Because, before the 80s of the 20th century, the social productive forces were limited, people could not change clothes all the time, and if you wore old clothes for a long time, it was difficult to be sure that you would not have lice eggs, lice eggs, you would have lice. You know, there were a lot of lice in the wild back then.

There are two "phenomena" that can support this claim: First, there are many more lice on animals than in humans. Why?

It's because animals don't know how to bathe, how to keep clean, and don't know how to change clothes. Second, in ancient times, there were very few lice on the upper body of a large family, but there were always lice on ordinary people? It's because everyone is in a good situation, you can take a shower and change your clothes.

Ordinary people don't have this situation, so many lice. This time, friends should know why there were lice on people in the past.

What are the lice on our body coming from? What kind of species is it?

In the past, the medical and health conditions were relatively poor, and the crops needed to stay with livestock, and people did not have a good sense of cleanliness and hygiene habits, so there were many lice, but now the medical treatment is developed, people's health awareness has also improved, and there are more cleaning products, and there are no lice.

In the past, poor sanitation conditions easily led to the spread of lice, and in the countryside, people had to deal with animals every day, which was easy to cause lice on animals to spread to people.

A large proportion of lice are found in domestic animals. In the past, the conditions did not support the prevention and eradication of parasites, but now the standard of living in the country has been greatly improved, so lice are now rare in people.

The reason why there are no lice now is that everyone pays great attention to hygiene, so there is no such thing, lice are a fungal infection, mainly through unclean **.
