How did the lice on people come from in the seventies and eighties?

They bathed very rarely, and there was no laundry detergent at the time, which allowed the bacteria on their bodies to grow into the ultimate lice.

Because the conditions of people in this era are very poor. Their clothes cannot be washed in a timely manner. The body cannot be cleaned in time. Over time, it will be very dirty, and lice will grow.

At that time, people were poor, hygiene was poor, and lice were born on their own.

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?

Because a few decades ago the standard of living was not very high, and they did not have many places to bathe, now with the improvement of living standards, there are places where you can bathe in every family, and lice do not have the conditions to survive, so it is becoming less and less.

Because decades ago there weren't as many cleaning products as there are now. So sometimes the body will be very dirty, so there are lice. And now people are getting cleaner and cleaner, so there are no lice.

In the past, people lived in a lot of soil, and it was relatively dark and damp, and people could not bathe often and use good toiletries, but now people live in a clean and dry place, and can wash at any time, so now there are few lice on people.

Because people now use a lot of shower gel to bathe, and people are now more clean and hygienic, these aspects help to kill lice, so lice rarely appear on people now.

Now that people are living in the best place, they pay more attention to the quality of life, and they usually pay attention to hygiene, and lice rarely appear.

Because people at that time did not pay much attention to hygiene, and the conditions were difficult, lice were transmitted through direct or indirect contact, and if they had direct contact with a person with pediculosis, or came into contact with a person's headscarf, hat, clothing, and bedding, it could cause the spread of pediculosis.

At that time, people could not take a bath often, and some could even wash once a year. If you don't take a bath all year round, you can easily attract lice.

It is precisely because of the shortage of various resources in the seventies and eighties that people do not bathe often, so it is said that there will be such things on their bodies.

It came from pets and poultry, because in those days pets and poultry were free-range.

I think it's because it's so dirty, because the sanitation at that time was very poor, and everyone was dirty.

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

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.

There were lice in the eighties who were willing:

The main reason is that the economic conditions and sanitary conditions are too poor, and people do not take a bath and do not wash their hair. Even washing, there are no detergents, with pesticides, etc. It can also be said to be a standard ecological environment!

You can't completely kill lice when you have lice, you can only kill some of them manually, and the lice can reproduce too quickly, so there are so many lice on people.

1. There is no place to bathe, especially in rural areas, and the number of baths is less, which provides conditions for long-term parasitism of lice.

2. Living in poverty, there are few clothes that can be used for washing, and you can't change clothes frequently.

3. Lice will parasitize pigs, sheep, cattle, etc., and there are many of them. At that time, the rural pig barn and cow barn were close to the houses of the residents, and people had to feed, add grass, and set up cars, and there were many opportunities for contact with the livestock that parasitized lice, which provided good conditions for the spread of lice to people.

4. At that time, almost all the families slept on a big kang, and they could sleep several people in a row. If one person has lice, the whole person on the kang will pass it on.

Although the standard of living has changed dramatically compared to the past, when I talk to the elderly in the countryside, I still often hear them talk about the past. Some people often say that many foods are not as delicious as before, such as pork is not as fragrant as before, watermelon is not as sweet as before, and chicken is not as delicious as before.

In addition to these, I will also talk about some of my worries in the past. For example, in the 80s, in the countryside, almost everyone had lice, but now they don't. Why is that? Was it because of the lack of hygiene in the past, or was there another reason?

Nowadays, many post-80s and post-00s generations probably don't know lice, because many people have never seen lice look like at all. In the 80s, it was really a rarity if anyone didn't have lice on them. But today, if someone is found to have lice on them, it may be in the news.

I remember at the beginning of the year, the teacher of my daughter's class said that there was a student with a head grown, which caused a lot of sensation at that time, and many parents were very nervous.

First of all, it was caused by the environment of the countryside at that time. In the past, it was common for every household in the countryside to raise a lot of poultry and livestock, such as chickens, ducks, geese, pigs, dogs, cattle and sheep. And many animals are still free-range, and farmers often come into contact with them.

In this way, lice from these poultry and livestock can be transmitted to humans. In addition, the environment in the countryside at that time was not good, and many crops also had lice eggs, which then fell on people's bodies and hatched after a period of time.

At that time, it was not that they did not love hygiene, but that the sanitary conditions were generally poor, so lice appeared.

There are other reasons. In the 80s, rural life was backward and the environment was poor, and straw was used all year round to pad under the mattress, which was easy to grow lice.

In the countryside in the 80s, almost everyone had lice, not because they didn't care about hygiene, but because there were no natural enemies to remove lice at that time.

I don't like to pay attention to hygiene, and people rarely take a bath and wash their hair at that time, so lice grow a lot.

I think it was mainly for hygiene reasons, because the rural environment was poor at that time and there was no attention to personal hygiene, so it was easy to get lice.

In the countryside in the 80s, almost everyone had lice, not because they didn't love hygiene, because people lived a hard life at that time, and they were working hard to fill their stomachs, and they didn't have the energy to clean up after themselves.

In the countryside in the 80s, almost everyone had lice, in fact, it was largely caused by the restrictions on living standards and health levels.

I can't grow anything right now.

When I was a child, I lay down on the pillow of the neighbor's nanny for five minutes! There was one, but it was quickly extinguished.
