Why do people get lice, and what should I do if I get lice on my body?

For the prevention and control of lice, first of all, we must do a good job of cleanliness and hygiene, do a good job of our own cleanliness and hygiene, change clothes frequently, wash hair frequently, and bathe frequently. In addition, we should also do a good job of the hygiene of our home environment, so often wash our floors, carpets and clean all kinds of environments in our home.

Suggestions: Use high temperature to kill lice, then when lice are found, we can kill the adults, nymphs and eggs of lice at 65 degrees Celsius, as long as it takes 15 minutes to 30 minutes, so as to achieve the purpose of controlling lice. The third is drug fumigation, drug fumigation, we can not use it casually, we need to carry out under the guidance of experts, the commonly used drugs are methyl formate and other drugs, this kind of medicine is relatively safe for humans and animals, but its dosage, and the period of medication should be carried out under the guidance of experts.

In addition, there is traditional Chinese medicine, the hundred parts of traditional Chinese medicine have a good insecticidal effect on lice, and often use the hundred parts of the alcohol soaked in the hundred infusion, which is used to kill lice, and the effect is very good.

Long-headed lice are mainly caused by infection, mainly by wearing hats to each other, using combs, and playing together.

First cut the hair short, then wash it with shampoo, then rub it on the scalp for a few minutes with Yujin Shile Essence Balm, and rinse it off with water. Stick to it for 5 days.

After washing with hot water soap with a comb, hat, bandana, pillowcase; Pay attention to cleanliness and hygiene. Don't use other people's belongings casually.

You need to bathe and change your clothes frequently.

Long lice are a type of parasitic disease, and there are many types, such as head lice, pubic lice, and body lice, which are named because of the different parasitic sites.

Most of them are caused by bad personal habits, or not paying attention to personal hygiene, or coming into contact with people with head lice, or animals. This is because lice are usually parasitic on the hair of humans or animals.

Adults and nymphs of lice suck blood on the host for life. Lice have a lifespan of about six weeks, and each female lays about ten eggs a day, which adhere firmly to human hair or clothing.

Ways to get rid of lice:

1.Blanching: lice are not heat-resistant, 50 degrees Celsius, 30min can remove lice and eggs.

2.Dry heat: For sweaters, leather jackets, cotton clothes, bedding and other items that are afraid of moisture and high heat, dry heat can be used to kill lice, and the temperature should be maintained at 65 80 degrees Celsius for 30 60min.

3.Medication**: You can use Yujin Shile Essence Cream, use it 2-3 times a day, and insist on it for about 5 days.

Spray the peacock directly with a fly toxin solution or treat it with medicine.

Put it on warm water with sterilized toilet water, soak it in it for a few minutes, or scrub the whole body, and after a few times, the packet will be eliminated

Take a bath and pay attention to hygiene.

1. Lice **

Lice are a parasite that can be found in both animals and humans. Humans are parasitized by lice since ancient times. Lice can spread through clothing, bed sheets, towels, etc.

For example, if a person with lice stays in one place, it is easy to leave the lice in that place, and the next person may be infected with lice when they enter the place. In addition, lice can also be infected by lice through contact with people who are infected with lice.

It is important to note that lice do not usually stay on humans for long because they need blood for food, and as long as there is no blood flow on the body, lice do not choose to stay on the body.

2. The harm of lice

Lice aren't just disgusting to look at, but more importantly they can cause discomfort. First of all, the mouthparts of lice can puncture human ** and suck human blood, which can cause pain in humans. Secondly, when lice suck human blood, they may transmit some parasites, viruses and other microorganisms, which can cause diseases.

For children and the elderly, the harm of lice is even more obvious. Because the child's body immunity is relatively weak, and lice will steal the nutrients in the body when they are parasitic, resulting in an imbalance in the child's body nutrition; The ** of the elderly is relatively thin, and the bite of lice is easy to cause dermatitis, serious infection and other problems.

3. How to prevent lice

In order to prevent the production of lice, we should do a good job in the following aspects:

1.Maintain personal hygiene: Keep your body clean, take frequent baths, change clothes, wash bed sheets** and other items to minimize the living environment of lice.

2.Maintain environmental hygiene: ventilate and clean the room frequently, and clean up accumulated stains and garbage in a timely manner to minimize the chance of lice growth and reproduction.

3.Correct use of drugs: Some drugs can kill insects, such as sulfur oil, lice water, etc., but when using drugs quietly, they should be used according to the instructions and should not abuse drugs.

4. How to ** lice

If you find yourself or someone else bitten by lice, you should take the following measures promptly**

1.Wash the bite site: Wash the bite site with soapy water or alcohol to avoid infection.

2.Topical cold compresses: Dry ice or ice can be applied to the bite site to relieve itching and pain.

3.Prevent infection: If the symptoms are obvious or the infection at the bite site is obvious, you should consult a doctor in time to obtain scientific methods.

Problem description: Why don't you bathe often If you don't change your clothes for a long time, you can get lice? Lice come from? It can't be that people have lice eggs on their bodies all the time, right? Rice can also grow worms when left for a long time, where do these bugs come from? Is it the rice itself, or is it floating in the air?

Analysis: When it comes to the parasite "lice", everyone probably has a sense of disgust. However, it is by studying two types of lice that parasitize on the human body that American scientists have recently speculated that the ancestor of today's human beings, "modern man", and the ape "Homo erectus" may have had "close contact" during evolution.

Scientists at the Florida Museum of Natural History in the United States report in the latest issue of the Public Biology Library webjournal that they have studied two types of lice that are present in all species today. Surprisingly, although the morphology of these two body lice is almost identical, their genetic material, deoxyribonucleic acid (DNA), is very different. Judging by the differences between the two, they diverged on the path of evolution as early as 1.2 million years ago, when they were parasitic on different races of people living on different continents.

So, why do two completely different lice parasitize modern humans? One of the most likely explanations, the researchers believe, is that one of the lice has been parasitic on our ancestors, "modern humans." And 20,000 years ago, when "modern humans" began to multiply in Asia, another type of lice was transferred from "Homo erectus", who also lived in the region at that time, to "modern humans".

Researchers point out that only direct contact such as fighting, wearing clothes, or ** can transfer lice from one species to another. Therefore, it is certain that "Homo erectus" must have had close contact with "modern man" before it became extinct.

Some experts disagree, with Max Planck, an expert in human evolution at the German Institute for Evolutionary Anthropology, saying that the findings were based on the premise that the common ancestor of the two body lice lived 1.2 million years ago, and that the age of this was determined by the number of body lice at that time. Therefore, if the estimate is wrong, the conclusion of the study is also wrong.

Still, scientists point out that lice and other parasites are very useful for studying human evolution, and it is only when two hosts come into contact that they can transfer from one host to the other and begin to reproduce. "No matter what evolution humans have undergone, lice are recording exactly the same history," the researchers said.
