Scientists have shown that mosquitoes are selective in their bites, bringing rich cholesterol and vitamin B to the mosquitoes most favored by people. Mosquitoes use the smell from the crowd to find the most suitable for their “appetite” object. Cholesterol and vitamin B these two substances are mosquitoes and other annoying insects necessary for survival, but they can not produce their own nutrition. O blood type people generally long life; A blood type people almost no immunity to smallpox, mosquitoes also love to bite them; B blood type people rarely get cancer; and AB blood type people have a high muscle immunity. Mosquitoes are relatively less interested. Mosquitoes have a strong ability to smell. When humans exhale carbon dioxide and other odors, these odors will be spread in the air, and these odors are like the opening bell, telling mosquitoes a good meal is just around the corner. Mosquito tracking its target, always with the human exhaled odor zigzagging forward until contact with the target, and then fall to the skin patiently looking for a “breakthrough”, and finally the “syringe” directly into the skin to suck blood for 8-10 seconds. Most cosmetics contain stearic acid (a fatty acid), so people who wear makeup than people who do not wear makeup more by the mosquito “welcome. As for a person’s cholesterol levels, but will not affect the judgment of mosquitoes, unless there is enough cholesterol stored in close proximity to the epidermis. Of course there are some odors that mosquitoes hate, such as bay leaves, lemongrass oil, lemongrass, garlic and the smell of geraniol. Another study shows that pregnant women are mosquito bites than women who are not pregnant chances are 1 times higher. Researchers believe that: women during pregnancy exhaled gas contains a variety of different chemicals, thus becoming the target of malaria mosquito bites. In addition, pregnant women’s body temperature is higher, sweating is also more, is a good base for the breeding of skin bacteria. These two reasons make pregnant women than other women are more likely to get mosquitoes “patronage”. Mosquitoes do have this “tendency to eat”, which is not people imagine that some people have delicate skin, blood sweet attract mosquitoes, the main reason is because of its body of some breath to attract mosquitoes. Generally speaking, the following kinds of people mosquitoes will also be its “love”: 1, sweat glands developed, high body temperature people. People who like to sweat, the acidity of the enhanced blood, the sweat discharged makes the body surface yellow information, moderators please delete the acid value is high, the attraction of mosquitoes. In addition, the mosquito’s tentacles have a heated body, it is very sensitive to temperature, as long as there is a little temperature change, it can immediately detect, sweating people’s muscle heat dissipation fast, will also be attractive to mosquitoes. 2, tired or faster breathing rate of people. People engaged in sports or physical labor after breathing will accelerate, some people have greater lung capacity, or breathing rhythm itself faster. This exhaled relatively more carbon dioxide, carbon dioxide gas will be in the head about 1 meter or so to form a moist warm airflow, mosquitoes are more sensitive to this, will smell and smell. This means that your body has been overwhelmed, should immediately go home to rest, do not overdraw physical strength, so as not to cause greater problems. 3, people who like to wear dark clothes. Mosquitoes are ambulatory, mainly because they have a tendency to dark habits, if wearing dark clothes, at night will present a black shadow, mosquitoes will chase to a darker place and go. Clothing color such as black is the preferred object of mosquito attack, followed by blue, red, green, etc., mosquitoes do not love to bite white. Similarly, mosquitoes love to bite people with darker or reddish complexion. 4, fast metabolism of people. Therefore, children are vulnerable to mosquito bites, the elderly is the opposite. 5, people who drink alcohol. People in drinking, eating beef and lamb or after taking antihypertensive drugs, will also become vulnerable to mosquito bites. Mosquito repellent device should have a role, but the best way to repel mosquitoes in summer should be a mosquito net it. How to “refuse” mosquitoes “gift” of “red packets”? 1, after exercise should be showered as soon as possible to keep the skin fresh. Hot days and sweating, to use paper towels, handkerchiefs to wipe away sweat. 2, if more mosquitoes in the place of daily activities, should be dressed in long-sleeved clothes. This is not because the body more layers of cloth, mosquitoes will not be able to use the mouth needle to suck blood. In fact, the mosquito’s mouth needle is very sharp, even cowhide and thick jeans can penetrate, the summer wear clothes simply unbearable “bite”. The function of the clothes is mainly used to cover the smell of sweat and other skin secretions, so that mosquitoes can not track and come. 3, outdoor sports best to wear white clothes, because white clothes reflective ability, have the effect of repelling Aedes aegypti. 4, do not wear socks in summer because it is too hot, which will make the smell of sweat quickly evaporate, the mosquitoes attracted to other parts of the body to launch attacks. Wear good sweat-absorbing socks can not only effectively reduce skin humidity, but also to cover up the smell. 5, to the mosquitoes should not use perfume and other odor-rich places.
