In summer, some people are easily bitten by mosquitoes, while others are not. Why?

There is a lot of warmth and beauty in summer, but there are also annoying mosquitoes! At this time, all we have to do is drive away mosquitoes. Some people get scared when they hear the sound of mosquitoes, hoping that this species will become extinct on the earth. In the office or in the car, when a mosquito sees a spot, it "bites" your foot and wants to fall asleep in bed at once, but it "purrs" in your ear, just like Tang Priest chanting. According to the entomology laboratory of the University of Kentucky, mosquitoes don't like everyone's blood. Most mosquitoes like sweets and beer lovers, because both alcohol and sweets will raise the body temperature of drinkers and make them sweat more, thus attracting mosquitoes.

Sometimes when you are in the same place with other people, mosquitoes often chase you and bite you, perhaps because you unconsciously become a mosquito magnet. Doctors and experts want to tell you that this is actually the case! "。 Who else does mozzie like? Athletes release a lot of lactic acid during exercise, while mosquitoes like the smell of lactic acid on their skin. Exercise will also raise your body temperature. Therefore, after exercise, the skin temperature rises and lactic acid secretion increases, making it difficult to attract mosquitoes. Obese human mosquitoes have an maxillary antenna and are extremely sensitive to carbon dioxide. A study in 2007 found that the tentacles of mosquitoes can sense the level of carbon dioxide 50 meters away. People who produce more carbon dioxide are more attractive to mosquitoes. Generally, overweight people, the more vigorous their metabolism, the more carbon dioxide they exhale and the more mosquitoes they have. Pregnant women and babies have higher body temperature, faster metabolism, more volatile substances on the skin surface and heavier body odor.

These are all signs to attract mosquitoes. People wearing dark clothes have dark surroundings and are mosquitoes' favorite. If you wear dark clothes, the reflective effect will make people's vision slightly dim, thus attracting mosquitoes. So wearing bold colors such as black, red and dark blue will attract mosquitoes. Special reminder: whether mosquitoes recruit or not has nothing to do with blood type. Mosquitoes are attractive for many reasons, but most of them are related to temperature, sweat or the color of clothes, not your blood type. Some people on the Internet say that blood type O will attract mosquitoes. This paradox comes from a poorly designed test that only considers blood type, but does not consider sweat, lactic acid or carbon dioxide. Mosquitoes are really annoying. They not only buzz in your ear, but also stare at your skin mercilessly, leaving you with a few mosquito bags that make you itch and can't help scratching all the time. But the most terrible thing is that the harm of mosquitoes is far more than that.

Mosquitoes not only "give" you itchy "red envelopes", but also spread various diseases at will, which is extremely hateful. If you accidentally take a big bite, it will make you itch and scratch, leading to redness, allergies, and even a cold and fever caused by the virus. For mosquitoes! Try not to light mosquito-repellent incense! The effective components of most mosquito-repellent incense are pyrethroid insecticides, organic fillers, adhesives, dyes and other additives. Therefore, the smoke of mosquito-repellent incense contains many harmful substances, which may cause asthma and other diseases. The tiny particles released by mosquito-repellent incense will enter and stay in the lungs, which will lead to asthma in the short term and cancer in the long term. Then there are carcinogens produced by incomplete combustion of mosquito-repellent incense basic materials, and some compounds that can stimulate the upper respiratory tract will poison the nervous system.
