There are so many people in this world.

There are so many people in this world,

In the crowd, a mosquito flew.

My fascinating eyes last,

In the middle of the night, you have no shadow.

There are so many people in this world,

What a sin, a mosquito only loves me,

The morning and dusk in this long fate,

I often let me, the bag out of the bag ...

Bleak

After singing, I still can't figure it out.

Why do you go to work, eat, watch TV, swing dragon door array, play mahjong, walk, and the pig teammates, girlfriends, and colleagues next door will always be good.

Below, Dr. Li Mengmeng from the Department of Dermatology of Huaxi Hospital of Sichuan University will come to tell you what kind of people who like mosquitoes, and now so many methods of mosquito repellent and mosquitoes are reliable and which are rejuvenated.

1

Not all mosquitoes will bite people blood sucking

There are thousands of mosquitoes in the world, but not all mosquitoes will bite people blood blood. Male mosquitoes generally do not bite, but mainly sucking the juice or nectar of planting plants. Both the vampires are female mosquitoes, because their ovaries require a lot of protein to develop eggs, and the juice or neither of the plant's juice or neither of them requires the blood of people or animals to meet the demand for spawning.

No matter how high the floor is, there will be mosquitoes

I do n’t know how many people were buying a house when they were buying a house.

Don't underestimate the little worms like mosquitoes. Although the wings of people are not inciting for birds, they are really flying!

Many studies have confirmed that mosquito is a fighter in the aircraft. In 2019, a research team from the National Institute of Health in the United States published an article in a very good magazine "Nature" to study the mosquito flight ability. Essence With the help of the wind, they not only flew far, but also flew high. In the space 40 to 290 meters above the ground, mosquitoes were found, and the number was a lot.

What is the concept of 290 meters? For example, the Gemini Tower of the Financial City is high enough, but the height is 218 meters. The IFS building on the Chunxi Road feels higher, yes, but the height is 248 meters, and the 10th floor is 10 floors from 290 meters. It looks like. So don't feel that mosquitoes can't fly up.

The lights come out, not because of the good vision of mosquitoes

Do you find that all mosquitoes appear in the middle of the night, and the lights buzzed at a level off. Wait for you to turn over and open the lights to open the light, but then quietly, because the mosquito has good vision, and I saw the lights turned on the lights. Just hid?

In fact, mosquito bite people does not rely on vision to lock the target, but to "navigate" themselves by the temperature, carbon dioxide concentration and odor in the room.

The human body itself exudes high calories, causing the surrounding temperature to rise, and breathing will also produce high concentration of carbon dioxide. These factors can allow mosquito to lock you without vision. In order to take a few more buns, mosquitoes will incite wings to find opportunities around. It stimulates the wings very fast, which can reach more than 600 times per second. This kind of annoying buzzing sound appears. And when you turn on the lights, the light will emit calories, and the mosquito will suddenly be aggressive in a short time. Mofa 100%locks where people are, and naturally will slow down.

After being bitten by a mosquito, the first reaction of many people is to pick and pinch it, because the bite will itch. This is because the mosquito is bite and blood, and will also inject saliva into the human body. The protein in the saliva will be Causes a slight immune response to the human body, and then releases a histamine, which makes you feel itchy.

But in fact, after being bitten by a mosquito, in addition to itching, there may be some serious consequences.

1

Infect

When mosquitoes injected saliva into the human body, the first reaction of the skin is to start a bag. Most people may just be a small bag. Some people with strong reactions. This bag is swollen than ordinary people, and it will be painful, even Pustcts appear infected.

In addition, after many people were bitten by mosquitoes, they all liked to go to the bag. If they were not enough, they had to pinch a rice, and then they were chrysanthemum. Although the moment of is comfortable and not so itchy, it is really easy to cause infection. Especially the little milk baby's skin is delicate, and after being bitten by mosquitoes, it is more prone to infection.

2

infectious disease

Compared with a bunch of bags on the body, the greater risk after being bitten by mosquitoes is that it will spread a variety of diseases. According to incomplete statistics, there are more than 80 types of pathogens and diseases that can be spread by mosquitoes. Type -type encephalitis, yellow fever, etc. This is also the most important reason for everyone to do a good job in mosquito prevention.

ask:

"Doctor, although I still want to ask, will mosquitoes infect AIDS and new crown viruses?"

Answer: According to the current research, no.

Mosquito transmission virus is actually a very complicated process. Scientists have studied AIDS's spread for many years. At present, a positive conclusion has also been obtained: 1. Mosquito will not spread AIDS; 2. AIDS virus will not survive in mosquito bodies. Reproduction; 3. No cases in the world were reported to AIDS by mosquito bites.

For the new crown virus, the World Health Organization has also officially responded. So far, there is no evidence that the COVID-19 can be spread through mosquitoes. three

Sometimes mosquitoes are particularly dedicated. Even if there are several people sitting at the same time under the same roof, it prefers some people and stares for bite. In fact, mosquitoes like you so much because of some characteristics on your body, making it easier for mosquito to find you. For example, the following five types of people are easy to get mosquitoes.

the first sort

Fat and love sweaty people

The fat man is afraid that you love sweating. Everyone knows that it is not enough to say. There are also some metabolism people who sweat more, and mosquitoes like you to be hot.

Second category

Sportsman

After exercise, the body's temperature rose and exhaled a large amount of carbon dioxide, accompanied by a strong sweat, which was equivalent to the active beckoning to mosquitoes and called it to come to you quickly.

Third category

Pregnant mothers, infants

The body temperature of pregnant mothers and little milk baby will also be higher than ordinary people. There are more carbon dioxide, and mosquitoes must not let you go.

Fourth category

Those who love "Stinky Beauty"

Most cosmetics and skin care products have odors. Some of them are derived from a substance called "hard fat acid". In the study Friends, it is more likely to be aimed by mosquitoes!

Fifth category

People wearing dark clothes

Dark clothes are more likely to absorb light and calories, so it is easier to make mosquito notice you than to wear light -colored clothes.

ask:

"Doctor, isn't it that type O blood is easily bitten by mosquitoes?!"

Answer: Mosquito is very smart and capable, but it has not been able to discriminate human blood types across the skin, so the mosquito bites you with your blood type without any relationship! Don't believe you ask you around you, type A, B, and AB have very mosquito people.

Ask again:

"Do you, I don't like to be fat nor sports, have no pregnancy, do not like to wear dark clothes, but a mosquito is to stare at me to bite?!"

Answer: Although there are many related research on mosquitoes, even many researchers do not hesitate to contribute their arms and blood to let mosquito bite, just want to understand it thoroughly. However, while deepening it, some problems are still found to have no solution, so in response to this situation, we persuade you, so don't think about it. King.

Preferred mosquito net

It can effectively isolate mosquitoes and does not contain any chemical preparations. But mosquito nets are not universal. For example, put a mosquito in accidentally, oh open, that is simply bite inside.

Other physical mosquito repellent

Except for mosquito nets, mosquito anti -mosquito, electric mosquito, screens, and gauze are all good physical mosquito repellent tools.

outdoor

It is recommended to use mosquito repellent water, mosquito repellent spray, etc., especially the following four ingredients are the most annoying taste of mosquito:

1

Moisturine

Its taste is easy to volatile, similar to the taste of human sweat, and it takes effect by blocking 1-ethyne-3-alcohol that blocks insect's olfactory receptor. It is recommended that children can be used for more than 2 months, and the concentration does not exceed 30%.

Answer: Mosquito repellent stickers and mosquito repellent bracelets may contain the above four ingredients. After all, it is worn on the hand, on the feet, and put it on the clothes. The role cannot be said to have nothing, but it can be said that it is very limited.

five

As I said earlier, in order to prevent infection and swelling, it is not recommended to scoop up the packets bitten by mosquitoes, let alone catch or pull. Facing the packets sent by mosquitoes, the processing is correct:

1 You can rinse or apply cold water;

2 If itchy, you can use camphor, mint ointment and compound coating agent under the guidance of a doctor, or oral anti -group amine, such as deedtiidin, Simetlizine, etc.;

3 For continuous bite reactions, it is necessary to use glucocorticoids locally.

Under the guidance of a doctor, children can use weak effects to medium -effective glucocorticoids in the short term, such as ground Needa, bran acid Momatson, etc.; Adults can use strong or super -efficient sugar corticosteroids, such as halogen,; of course, it is not advisable to, it is not advisable A variety of joint use, and it is usually unnecessary for long -term applications;

4 If the abscess blisters occur with the infection, use antibacterial ointment under the guidance of a doctor, such as Fuzyi acid, Mapiro Star, etc. ask:

"Doctor, I took my baby in my old life, and I like to apply water to the baby's bag. Do you want to persuade them?

Answer: This movement in the old life is that saliva can disinfect and swell. In fact, 99%of people's saliva is water, and the rest is some organic matter and inorganic objects. They do not have the effect of disinfection and swelling, let alone itching. It is painted on the mouth, the baby is useless, and you are useless.

Du, brave

You are flying to fly, you, buzz, you make mistakes

Do not hide

My forehead bag, mine, itching, my despair

Whether it is a blood -sucking youth, you

Still me in the dark at night,

You look like me so much

They are all lonely people in life ...
