Summer is the season when mosquitoes are rampant. Will mosquitoes attack you when you get up early in the morning? What blood type do mosquitoes like best? Why do some people especially like mosquitoes? Do you know why? Let's have a look.
O. Type B bite more
Different kinds of mosquitoes have different 'tastes'. For example, Anopheles sinensis, which spreads malaria, likes to suck type B blood. According to the experimental results, people with type B blood are most vulnerable to the attack of Anopheles sinensis, followed by type a blood. Aedes aegypti, which spreads yellow fever and dengue fever, likes to bite people with type O blood.
Mosquitoes also like to bully women and children
Secondly, mosquitoes are also very fond of biting black clothes. Wearing black is the best way to attract mosquitoes!!!
Wearing dark twill jeans is easy to bite
For mosquitoes, the carbon dioxide and sweat emitted by the human body are effective information to guide them to find prey. It mainly relies on the olfactory organs, that is, the upper corner of the head, to sense the 'information' from the air and follow it. Don't look down on mosquitoes that are less than one centimeter long. They have a strong search ability. The longest distance they can search is 60 kilometers. In this range, the stronger the 'signal' target, the easier it is to be locked by them.
Because of the relatively high concentration of carbon dioxide around, the 'image' presented in the mosquito's field of vision is relatively clear, which is convenient for the mosquito to conduct directional tracking. Therefore, in a group, people with large lung capacity, fat people and people with heavy breath are more likely to be bitten by mosquitoes. Pregnant women are active in metabolism and exhale higher carbon dioxide.
Sweat from the human body evaporates in the air and can also send a 'signal' to mosquitoes. Usually, people who sweat a lot and are prone to sweat are more likely to be attacked by mosquitoes, which is enough to explain why we often find out that there are several big 'red envelopes' on our bodies unconsciously after exercise. Mosquitoes love to bite people with rough skin and large pores, usually because such people tend to have developed sweat glands or discharge more secretions such as sweat. Therefore, sometimes men are more attractive to mosquitoes than women and young people than old people.
It has been found that women 'recruit' mosquitoes especially during menstruation or pregnancy, which may be related to the high level of sexual hormone secretion, so that 'mosquitoes like to bite sexy people'. Xu pointed out that this is actually because the endocrine of women in the above-mentioned stages has changed, metabolism is accelerated, sweat output is often more, and the stimulation and guidance of mosquitoes are stronger. In the same way, it's easy for teenagers in their developmental stages to recruit mosquitoes.
Before giving birth, a pregnant woman breathes 21% more than a woman who is not pregnant, and the exhaled moist gas and carbon dioxide are attractive to mosquitoes, according to data. In addition, the abdominal temperature of pregnant women was 0.7 times higher than that of non pregnant women, and the higher the body temperature, the more volatile substances on the skin surface.
If you don't dress properly, you will attract mosquitoes. It turns out that mosquitoes are afraid of light but don't like too dark light. They like to suck blood in low light environment. During the day, when people are wearing dark clothes, the reflected light is darker, just like it is. In addition, mosquitoes like to bite people with high temperature, while dark clothes have strong heat absorption ability. When several factors are added together, the mosquito attraction index of dark clothes will increase greatly. People often think that black clothes are the most attractive for mosquitoes, but in fact, wearing dark twill jeans is the most vulnerable to mosquito bites, according to Professor Xu.
