After the beginning of spring, many people have this feeling: mosquito activities are becoming more and more frequent.
It's really hateful, but it's helpless.
Mosquito repellent water, mosquito repellent liquid, and mosquito repellent patches are also indispensable.
But it still can't stop the mosquitoes from staring at you.
Obviously, I couldn't see many mosquitoes, so I scratched the "red envelopes" one by one on my body silently
The following picture of a child being bitten by a mosquito shocked many parents.
The child fell asleep one night when his ear was bitten by a mosquito. The next morning, when the mother got up to make milk for the baby, she was shocked to see the child.
The child's right ear is swollen with a big bag, like a "big ear Tutu", looking at the child's swollen ears and tears, parents really feel funny and distressed.
Many children are bitten by mosquitoes, and they will be swollen severely, which makes parents feel very worried. But there are also some children who are bitten and the reaction is not so severe, why is that?
In fact, when a child is bitten by an insect, its reaction depends on the child's sensitivity to the toxins released by the mosquito. Some children are highly sensitive to toxins and have a naturally very severe reaction.
In addition to causing redness, swelling and pain, it is also easy to cause allergic reactions, and the swelling will not go away for a long time.
Mosquito bites have always been a nightmare for many people. Not only do they cause stinging and itching, but they can also spread disease.
However, some people seem to be more likely to be targeted by mosquitoes than others.
This raises a common question:Why do mosquitoes only bite certain people in a group?
There is a common misconception thatMosquitoes prefer to bite people of a specific blood type.
It is said that mosquitoes are more inclined to bite people with blood type O and relatively less bitten people with other blood types.
This view has been circulating for some time, but its scientific basis is not sufficient.
In fact, there are 5 real reasons:Personal body odor, surface chemicals, personal habits and behaviors, home environment and attractiveness, as well as genetic factors and immune system
More on that below:
1.Personal body odor.
Mosquitoes will passPerceive the chemicals emitted on ** to select the bite target
Some people's body odor may attract mosquitoes, which is related to theirsMetabolism, diet, and personal health statusRelate.
In addition, mosquitoes pairCarbon dioxide and lactic acidChemicals produced in the body are sensitive, and these substances may be higher in some people, making them a preferred target for mosquitoes.
2.**Surface chemicals
Chemicals on the surface of the human body can also influence mosquito selection.
For example, mosquitoes on some **bacteria and microorganismsThere are preferences. Some people may have more of these microbes present on the **, increasing the likelihood of mosquito bites.
In addition, some people's sweat may contain specific chemicals such as:Lactic acid and ammonia, these substances are attractive to mosquitoes.
3.Personal habits and behaviors
Individual habits and behaviors may also influence mosquito bite choices. For example,Wearing dark-colored clothing attracts mosquitoes because they are more sensitive to black and dark-colored clothing.
Also, if you are active in mosquitoesGo out during peak hours, orExposed surfaces, all of which increase the risk of being bitten by mosquitoes.
Therefore,Personal habits and the use of protective measuresIt is closely related to the frequency of mosquito bites.
4.Family environment and attractiveness
In terms of the home environment, mosquitoesPrefer a humid and warm environment, as these conditions are conducive to their reproduction and survival.
If your home environment provides exactly that, then you are likely to be a prime target for mosquitoes.
In addition, mosquitoes are also easierInNocturnal or twilight activity, as the temperature is cooler and the humidity is higher at this time.
Household goods and chemicals such as:Perfumes, shampoos and laundry detergents, which may also be attractive to mosquitoes.
5.Genetic factors and the immune system
Genetic factors and an individual's immune system may also play a role in mosquito bite selection.
Studies have found that some people's genetics may make them more susceptible to mosquito attraction, while others have a higher resistance to mosquito bites.
Some studies have shown that:People with stronger immune systems have lower sensitivity to mosquito bites.
The spring day melts and sleeps, and when the sleepiness is thick in the morning, I am suddenly awakened by a buzzing sound that lingers in my ears. "What?! No, there are mosquitoes! That's right, although the spring cold is not over, the "mother mosquito" has really returned.
After the sting, the animals that have survived the harsh winter stretch their bodies, including the overwintering female mosquitoes. After a few spring rains, everything recovered, and the eggs that survived the long winter in hidden corners also sensed the signs of recovery.
Due to the lower temperatures in spring, mosquitoes grow much slower than in summer and autumn.
In summer and autumn, it only takes 2 to 3 days for female mosquitoes to mature from sucking blood to developing and maturing their ovariesIn the spring it is 10-20 days. It takes only 7-10 days for mosquito eggs to develop from eggs to adults in summerIn the spring, it takes more than 30 days.
Therefore, spring is the best time to eradicate the first generation of mosquito larvae.
Spring "overwintering mosquitoes" should not be underestimatedMosquitoes that have been hungry for a winter are particularly poisonous, sometimes even more severe than in summer. If you're not careful, you'll be able to get a big bag. The baby ** is very white and tender, which is what mosquitoes prefer. Because of this, parents should take protective measures.
Some people think that it is because the baby is young, delicate, and the blood is sweet, so it is so easy to attract mosquitoes. In fact, mosquitoes generally look for "food" through smell, which has little to do with sweetness, and the real reason is here, after parents understand, they may know how to prevent mosquitoes for their children.
1.The smell of children's sweat attracts mosquitoes
When the weather is hot, children are more likely to sweat from exercise, which is actually one of the reasons for attracting mosquitoes. We all know that the sweat discharged by the human body sometimes smells sour, and these sour smells have a fatal attraction to mosquitoes. The lactic acid produced by this sweat will make mosquitoes not far away smell the smell and rush to eat a delicious meal.
2.The child's "active" attracts mosquitoes
The amount of exercise of the child is much greater than **, and the child's metabolism is faster than that of ordinary people, exercise and metabolism exude a higher calorie and "popular" taste in the child's dignity, and the "bloodthirsty little maniac" who is naturally sensitive to temperature and smell can accurately determine the specific location of the child according to these at once.
3.The child's "breathing" beckons mosquitoes
Due to the imperfect development of the child's lungs, so under the same exercise, the child's breathing frequency should be higher, and the exhaled CO2 will be more, and these gathered gases will form a special smell of airflow in an area of one meter around the child, surround the baby, and the little mosquito can easily find the exact location to suck blood by following the smell.
It can be seen that mosquitoes love to bite children, not because the child's skin is thin and the meat is fragrant, but because the child's own "smell" is greater and more attractive to mosquitoes.
When a child arrives in a new environment, the rash is usually worse than that of the local childThis is because local children have tolerated it.
Parents are even more worried about the more than 80 mosquito-borne diseases, and dengue fever is one of them.
Among all the medical insects, it should be said that the most harmful is the mosquito.
In addition to bites, mosquitoes have transmitted more than 80 kinds of diseases, the most common of which are Japanese encephalitis, dengue fever, malaria, chikungunya fever, Zika fever, yellow fever and other zoonotic diseases, which can seriously disable and kill people.
Malaria affects 300 million to 500 million people worldwide each year, and it kills a staggering 1.5 million to 2.7 million people, including 1 million infants and young children under the age of five. Especially after the 90s of the last century, malaria has spread widely in many countries, ascending to the throne of the world's eight deadly diseases, and is the number one killer in Africa.
In the early years, the cumulative number of confirmed dengue cases in Singapore reached 35,315 and the cumulative number of deaths reached 32, which was the highest number of confirmed dengue fever cases in Singapore.But not every mosquito is capable of transmitting every virus. Certain species of mosquitoes transmit specific species of viruses, and such mosquitoes are called vector mosquitoes. For example, malaria mosquitoes transmit the malaria parasite, causing malaria in humans.
If a virus is absorbed by a non-vector mosquito, the enzymes in the mosquito's digestive system will automatically break down the virus and make it infectious.
Mosquitoes have been listed by the World Health Organization as the number one deadliest animal killer in humans. It is estimated that about 700 million people worldwide are currently bitten by mosquitoes each year to transmit various diseases, and nearly 700,000 people die each year from diseases transmitted by these mosquitoes.
What should I do if my child is bitten by a mosquito and is swollen and itchy?
Thousand! Ten thousand! No! Want! Use! Force! Scratch!
Remember! After the baby is bitten by a mosquito, the more he scratches it, the more itchy.
Because when tickling, the squeezing of ** by the fingers will accelerate the blood flow, so that the local anticoagulant protein and the histamine secreted by the body will spread to a larger area, and the bite will naturally get bigger and more itchy.
If a child is bitten by a mosquito, the most important thing is to deal with it as soon as possible, and we can deal with it from the following points:
1.Apply alkaline soapy water immediately, which can prevent bagging, redness and swelling.
2.If the bag is lifted, quickly apply a cold compressto stop the spread of inflammation.
For example, use an ice towel to cool the compress, or directly use a towel to wrap ice cubes in the cold compress, if there is a bottle of saline in the refrigerator, it is better, directly soak the disinfectant cotton or gauze and then apply a cold compress to the swollen area.
3.If it is very itchy, you can apply calamine lotion to relieve itching.
It is generally available in pharmacies, and infants and young children can use it with confidence. You can apply it several times a day, and you can rub it for a while after each application to let ** absorb, and don't scratch it to avoid infection. However, calamine lotion may have a slight peeling phenomenon after use, which is a normal reaction, so don't worry.
It is not recommended to use toothpaste to relieve itching, especially for the most damaged places, it is necessary to use it with caution.
5.If the injury is pre-existingDo not use insect repellent lotion that contains alcohol, not only will it stimulate the child's **, but the child will feel very painful, which is not conducive to wound healing. The baby's nails should be trimmed regularly to avoid being too itchy and scratched**.
6.It is not recommended to use wind oil essence and cooling oilAlthough this type of product can have a mosquito repellent effect and relieve itching, it has an effect on the nervous system and is not recommended for children under 2 years old.
Of course, it is more important to take precautions in advance than to treat your child's wounds afterwards! Parents are advised to carry out mosquito prevention work now to prevent their children from being attacked by mosquitoes.
Lived with mosquitoes for n years.
Do you really understand it?
Mosquitoes drink your blood, just like you drink bubble tea. You drink milk tea and pearls, while mosquitoes drink plasma and blood cells. The mosquito stops, and it kind of sucks some fat and walks away.
If the blood-sucking mosquito is so annoying, why not wipe it out in one fell swoop? It can only be said that the strength does not allow it.
Eliminating mosquitoes may destroy the earth's ecological chainSome scientists have done a "sterilization plan" for mosquitoes by modifying male mosquitoes, but mosquitoes are intertwined in the biological world, and they cannot be eliminated if they want to.
As the saying goes, to exist is to be reasonable. On the earth, as such a tiny species, it can survive for hundreds of millions of years, and there must be something special about it, and the natural world also has its necessity for existence.
The destruction of any part of the ecosystem is unimaginable. The role of mosquitoes in nature is to spread diseases, create plagues, and accelerate the death of other speciesMaintain ecological balanceMosquitoes (larvae) are also food for other animals.
What's more, only female mosquitoes bite。The male mosquito is so wronged, he has been scolded by humans for so many years, but in fact, he is a vegetarian.
Therefore, the war between humans and mosquitoes cannot be easily ended.
1. Check the blind spots of mosquito repellent at home one by one
1. The best environment for mosquito larvae to grow - a place with a lot of stagnant water
Mosquitoes are mainly caused by stagnant water, so there are potted plants in the homeRegularly clean up the plant tray from stagnant water and soil.
Also available in the bedroomPut a pot of mint, mosquitoes will hide from the smell of peppermint.
2. The favorite living environment of mosquitoes - a place with poor hygiene
Sanitary dead ends at home,For example, the back of the closet and sofa is not cleaned in placeIt can easily become a hiding place for mosquitoes.
2. Physical mosquito repellent
Mosquito nets and window screens are used
If at homeIf you have a newborn or baby who is active at home for a long time, the window at home must beInstall window screensIf it is inconvenient to install a screen door on the door, it is best to reduce the number of times the door is opened; When sleeping at night, it is also important to install mosquito nets to prevent your baby from being disturbed by mosquitoes
The air conditioner was turned on
Generally, when the air conditioner is on, the room temperature is relatively low, and mosquitoes will not move wildly, which can reduce the possibility of the baby being bitten.
Wear light-colored clothing
Mosquito bites have a lot to do with the color of the clothes people wear, if you wear dark blue or brown clothes, the probability of being bitten by mosquitoes will be greater, so in summer, Ma Ma should try to wear light-colored clothes for the baby.
Myth 1: "Children's mosquito coils" are safe and non-toxic, and children can use them with confidence
China does not divide the applicable population of specific mosquito coils into categories, such as **, children, and infants.
The so-called "children's mosquito coils" on the market are just gimmicks made up by some merchants themselves to attract customers to buy. In fact,Mosquito coils in China belong to the category of pesticide management, and its main mosquito repellent ingredient, pyrethrin, is low-toxicity or micro-drug。Therefore, mosquito coils generally have a certain toxicity, but the toxicity is very weak, but it is impossible to be completely non-toxic.
For younger children, it is best not to use mosquito coils too much.
Children's respiratory tract is not yet mature, and excessive inhalation of irritating smoke and dust is more likely to lead to damage to the respiratory tract; In addition, children with allergies or asthma should be more cautious when using mosquito coils.
Myth 2: Mosquito coils can be burned all night with doors and windows closed
Some people are accustomed to burning mosquito coils all night after closing doors and windows, believing that this is a better mosquito repellent. However, a survey report on 8 types of mosquito coils on the market pointed outThe emission of benzopyrene in the flue gas after burning a plate of mosquito coils is equivalent to the burning of 4 cigarettes, and the emission of polycyclic aromatic hydrocarbons (PAHS) is equivalent to the burning of 137 cigarettes.
It can be seen that mosquito coil smoke has become an important part of indoor air pollution.
Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals with AI-causing properties, while benzopyrene is the most toxic of the polycyclic aromatic hydrocarbon compounds. Inhalation of these substances in small amounts can be metabolized and eliminated in the body normally, but excessive intake can lead to genetic damage and increase the risk of cellular AI changes.
Myth 3: Mosquito coils can achieve the effect of completely killing mosquitoes
Many people may think that mosquito coils are an insecticide that completely kills mosquitoes. But in fact, the mosquito repellent effect of mosquito coils is higher than the mosquito control effect.
The main active ingredient of mosquito coils, pyrethrin, is a nerve agent for mosquitoes, which does have the effect of killing mosquitoes. But,Pyrethrin must reach a certain concentration to have a mosquito killing effect.
Generally speaking, the content of pyrethrin added to mosquito coils is not high, so the concentration of pyrethrin when burning mosquito coils in the room is low, which is not enough to achieve a complete mosquito control effect.
You can't hide from it in your life
Disgusting and scarypeopleWhat are the animals?
