Have you ever remembered the "winning lottery" of which lives could not bear last year?
Food stalls skewer beer, only you are lucky to be visited by mosquitoes.
In the same bedroom, mosquitoes only "buzz" in your ears, ready to leave a "kiss mark".
After dinner, go out for a walk, others have nothing to do, you are already a leg bag.
Are mosquitoes also picky eaters? If you can use search engines skillfully, you will definitely go online to understand:
"Blood Sweet Bitter Says": Mosquitoes love to bite people with blood sweet (star eyes).
"Blood type theory": Mosquitoes love to bite people with blood type O and blood type B (thinking face).
"Sexy to say": Mosquitoes love to bite people with high levels of sex hormone secretion and strong sexual desire (shy face).
"Good or bad skin": Mosquitoes love to bite people with smooth and white skin (proud lady's face).
The grumpy little doctor is also a person who is often picked by mosquitoes, but sorry, I have AB blood, Buddhist coldness, black and rough (for the rumors to go out!). As for whether the blood is sweet or not, I haven't tasted it, or you can try it?
Today, the violent brother will transform into a mosquito to "bite" these unreliable statements!
1, your human blood type, the baby does not understand ah
For a long time, the "blood type theory" about mosquitoes has been widely spread in the folk. The common saying is that mosquitoes prefer people with blood types O and B, and do not like people who bite blood type AB. But in fact, type A blood and AB blood have not been spared by rumor makers!
Therefore, mosquitoes like blood type O, blood type B, blood type A, blood type AB blood??? Perfect, but also genuinely fraternal.
In fact, mosquitoes do not understand human blood type at all.
Mosquitoes mainly rely on more than seventy kinds of odor and chemical receptors throughout the body, such as carbon dioxide receptors, taste receptors and heat receptors, to search for their targets. Mosquitoes can be precisely targeted at 50 meters through human exhalation and sweat[1], and they are particularly sensitive to carbon dioxide.
Mosquitoes prefer people with large pores, rounded bodies, and sweating to thin people. Especially in people who often sweat, there is lactic acid excreted on the surface of the skin, and the smell is particularly attractive to mosquitoes. So, people who have just finished exercising in the park are careful, sweaty and deep breathing, making it easy for you to become a mosquito's "lunch on the plate".
2, I love people who suck blood sweet? Don't make trouble, is it difficult to have sour, bitter, spicy blood?
Some people say that the baby's blood is pure and sweet, especially attracting mosquitoes. Some mothers will chase after their children and give them insect repellent creams and sprays. But according to this, isn't it easier for sugar friends to become "ding-dong households"?
Human blood pH is 7.3 to 7.4, is weakly alkaline, has a fishy taste, and has a slightly salty taste, and there is no sweetness.
Research from Wageningen University in the Netherlands found that the factors that affect mosquito bites lie in the different combinations of bacteria on the skin. These bacteria can make non-volatile substances volatile and odorous.
Research from the University of Florida in the United States shows that the bacteria mentioned above can produce more than 300 chemical components that change the body's odor, some of which attract mosquitoes and some of which can make you a "human flesh repellent" [2].
In fact, mosquitoes don't want to suck blood, and sucking blood is not just because they are hungry. The most likely to bite people are the female compatriots of the mosquito world, who need to improve their reproductive ability by sucking blood. Because people's blood contains substances that promote the maturation of mosquito eggs, such as cholesterol. If your blood is rich in these substances, the female mosquitoes must like you more. (Isn't that the fat man, who said he received 10,000 critical hits)
3, I can't tell the difference between men and women, but I want to throw myself into the arms of my pregnant mother
Whether you are a man or a woman, as long as you are identified, mosquitoes will send big red envelopes.
However, mosquitoes prefer pregnant mothers because the gas they exhale contains a variety of chemicals that can easily attract mosquitoes. And with the assistance of the fetus, the abdominal temperature of the pregnant mother is higher, the higher the body temperature, the more volatile substances on the surface of the skin, so pregnant women are easy to become "targets".
Small babies are even more difficult to escape the clutches of mosquitoes, "delicious meat", metabolism and sweat volatilization are faster than the average person, will produce more trimethylamine, has a strong attraction to mosquitoes Oh ~ ~ ~
4. Want to drive me away after drinking some wine? In fact, you are more "charming"
You're naïve to think that way. Alcohol can only smoke away girlfriends, mosquitoes can not eat this set.
Changes in body odor and breathing after drinking alcohol will make the mosquito quickly locate your position, making you the appetizer of the mosquito.
Mosquitoes still heavy taste. Sometimes, mosquitoes approach you, but they don't necessarily take their mouths, depending on the smell of your skin [3].
If you have also applied makeup and sprayed hairspray, there is a high probability that stearic acid in cosmetics will remain on your body, which can be more tempting to mosquitoes [4]. At this time, you are a walking "mosquito absorber", smelling incense and eating more fragrantly.
5, looking black is not necessarily my dish, or you wear a black dress to try?
Mosquitoes have long lived in dark environments such as sewers, and they have a special love for black.
But if you want mosquitoes to bite you, you must meet the characteristics of "full color and fragrance", and simple dark skin is not enough to attract them!
But when mosquitoes encounter carbon dioxide, they are attracted to dark-looking visual objects. If you add a black coat to your wheat-colored skin, you have a high probability of becoming a target of mosquitoes. Also, dark clothes absorb heat and raise your body temperature, and mosquitoes will immediately attract you to them.[6]
Through heavy screening, the following types of talents are the favorites of mosquitoes, let's see if it's you:
Goal 1: People with big heads and fast breathing;
Goal two: people who love to sweat;
Goal Three: People with fast metabolisms;
Goal Four: People who don't love to bathe;
Goal Five: People Wearing Dark Clothes;
Goal Six: People who love makeup.
Next, Brother Tyrant will teach you how to extinguish the arrogance of mosquitoes:
In summer, when it is early in the morning and outside is brighter than inside, mosquitoes will take advantage of this time to feed, and at this time, the windows can be opened to let the mosquitoes out.
Before returning home from work, look around before opening the door, observe whether there are mosquitoes on and around the body, and pat and pat clothes before entering the door.
Before sunset, close the doors and windows of your home to prevent mosquitoes from flying in after turning on the lights. However, the interior should also ensure ventilation and ventilation, if there are many mosquitoes, it is recommended to install screen curtains and screens on the doors and windows.
Whether it is mosquito repellent water or mosquito coils, it is not as reliable as physical mosquito repellent, in addition to screen windows, the home must be equipped with mosquito nets.
Wear light-colored clothes when you go out, and avoid places where mosquitoes gather, such as grass, flower beds, and ponds. If you want to go out, you can spray some mosquito repellent water beforehand. The "DEET" in the mosquito repellent water or mosquito repellent dew actually has a certain effect on masking odors, so that mosquitoes cannot find targets. It should be noted that the repellent water should be selected to contain "DEET" or less toxic "repellent ester" (BAAPE). Also, it is best not to use it for children under 2 years of age, and use it away from an open flame.
Dry or change into dry clothes as soon as possible after sweating.
In the summer, I use less perfume and hand cream.
In a word: less "waves" can prevent mosquitoes.
