Almost everyone has the unpleasant feeling of being "bitten" by mosquitoes, in fact, it should be said that they are "stung" by mosquitoes. Mosquitoes can't open their mouths, so they won't bite on the **, it actually uses 6 needle-like structures to pierce people**, these short needles are the center of the mosquito's edible mouthparts.
These short needles suck human blood in the same way that they draw blood; The mosquito also releases saliva containing anticoagulants to prevent blood from clotting, so that it can feast peacefully. When the mosquitoes are full of food and drink and float away, all they leave behind is an itchy lump.
However, the itchy sensation is not caused by a short needle pricking or chemicals in the saliva. We feel itchy because the body's immune system releases a protein called histamine to fight foreign substances, and this immune response triggers an allergic reaction at the bite site. Histamine causes swelling of the tissues around the bite when blood flows to the bite site to speed up tissue recovery, and the intensity of this allergic reaction varies from person to person, with some people having a more severe allergic reaction to a mosquito bite.

Mosquitoes first secrete an acidic poison on the surface of the human body to soften it before they can stab it and suck blood. After a mosquito bites, the bite will be swollen and itchy, which is actually an allergic reaction to acidic toxins. Immediately after being bitten by a mosquito, wipe the bite with soap, which can relieve itching and quickly reduce swelling, because soap is alkaline and can neutralize acidic toxins.
But wiping it long after being bitten has no effect.

1. Reason for bagging: After the mosquito bites, the bitten part will release more histamine, and histamine will cause part of the body fluid to penetrate into the subcutaneous, which will cause the phenomenon of local ** bagging. People with sensitive physique will have large bulges and even blisters after being bitten by mosquitoes due to strong personal allergic reactions;
2. Cause of itching: After being bitten by a mosquito, in the process of histamine against formic acid, the blood will accelerate the flow to the bite to help accelerate recovery, and a large concentration of histamine will lead to itching. In addition, when the capsule becomes larger, it will compress the peripheral nerves on the surface of the **, resulting in local itching.
If scratching is carried out, it will lead to the release of more histamine locally, and the more scratching will occur, the more itchy it will be, and it is recommended that the patient transfer the attention in time to avoid scratching as much as possible. If itching is intense, you can apply it topically with soapy water, other anti-itch sprays, or calamine lotion. If the infection is caused by scratching, anti-inflammatory and antibacterial** is required, such as a wet compress with a topical boric acid solution, and oral anti-inflammatory drugs, such as penicillin, metronidazole, etc.
If the allergy is severe, antihistamines such as loratadine, chlorpheniramine, etc., can be used under the guidance of a doctor. It is recommended that patients spray mosquito repellent as much as possible when going out, or wear long pants and jackets to reduce the possibility of mosquito bites.
Sweat contains a lot of amino acids, lactic acid and ammonia compounds, to which mosquitoes are very sensitive. Young people who exercise a lot, people who are fat, people who breathe heavily, and people who have a high body temperature are more likely to be bitten. Before labor, the exhalation volume of pregnant women is 21% greater than that of women who are not pregnant, and the exhaled moist gas and carbon dioxide are quite attractive to mosquitoes. >>>More

This is because it has a suitable breeding environment, which can be seen from the growth cycle of mosquitoes. First of all, the temperature, judging from the mosquito's reproductive cycle, when the temperature rises in spring and summer, the mosquitoes hatch from the pupae. Secondly, the calm and stale water is a place for mosquitoes to breed, and thirdly, the number of natural enemies of mosquitoes cannot eliminate more mosquitoes, and the ecology is unbalanced. >>>More
