World Mosquito Day | Do mosquitoes have favorite groups? How to prevent mosquito bites scientifically?

In the hot weather, many people are "favored" by mosquitoes and are often "kissed" by them, but some people are not "visited" by mosquitoes.

There were several people together, but no one else was hurt, only he was covered in rashes. So who are more likely to attract mosquitoes? What should you do after being bitten by a mosquito?

0 1Which groups of people are more "favored" by mosquitoes?

Mosquitoes detect and locate targets mainly through factors such as carbon dioxide, heat, and volatile chemicals. Therefore, the following types of people may be more attractive to mosquitoes:

First, people who emit more carbon dioxide , such as people with large lung capacity, obese people, pregnant women and children with relatively active metabolism; after drinking or exercising, the amount of carbon dioxide emitted will also increase. These people are more likely to become the target of mosquitoes.

The second is people with well-developed sweat glands and high body temperature . These people love to sweat, and the smelly lactic acid or other components excreted on the surface of the skin will attract mosquitoes.

Third, people who love to wear makeup will also have a higher chance of being bitten by mosquitoes, because perfumes, face creams and other flower-scented cosmetics may also contain chemical ingredients that attract mosquitoes.

In addition, wearing dark-colored clothes such as black and red is more likely to attract the attention of mosquitoes. Mosquitoes prefer to suck blood in low-light environments, because dark-colored clothes have no reflective effect on mosquitoes and are more likely to be bitten by mosquitoes. In addition, dark-colored clothes have a strong ability to absorb heat, and mosquitoes like to bite people with higher body temperatures, which increases the chances of people wearing dark-colored clothes being bitten.

After being bitten by a mosquito, do not scratch it even if it itches, because scratching will cause the release of histamine (an important chemical transmitter in the body), making people feel more itchy. Scratching may also form subcutaneous nodules and scars. You can apply ice cubes to relieve itching immediately; or pat the bitten area gently, and then apply wind oil, cooling oil, etc. After about 15 minutes, the blister will gradually become smaller.

0 2How to prevent mosquito bites?

Install screens and mosquito nets. Needless to say, this method can completely isolate you from mosquitoes and avoid being bitten by mosquitoes.

Clean up the debris and stagnant water in the room. Stagnant water is a necessary condition for mosquitoes to breed. Pay attention to cleaning the stagnant water in water tanks, flower pots, trash cans, discarded cans, etc. Remove debris, ventilate and let light in, and do not provide mosquitoes with a place to live.

Light mosquito coils. Although mosquito coils can kill mosquitoes, they can also harm human health if used for too long. Therefore, remember that the place where mosquito coils are used must be well ventilated.

Wear light-colored clothes when doing outdoor sports. When you are in places with many mosquitoes, try to wear light-colored long-sleeved clothes and socks. This will not only reduce contact between people and mosquitoes, but also reduce bites when mosquitoes sense that human skin moisture is reduced and volatile substances on the skin surface are reduced.

Use repellents correctly. Repellents are drugs that are applied to the body to repel mosquitoes. They can be applied to exposed skin, such as arms, face, neck, and calves. They are generally effective for 4 hours, and should be reapplied after this time. In addition, pay attention to whether you have allergies. The effectiveness of the drug is related to the amount of activity and sweating. If you are outdoors, the duration of the drug effect may be shortened, so you should apply it in time.
