Question 5: Why do you get red envelopes when bitten by mosquitoes? Mosquitoes inject a venom into people's skin in order not to be detected before sucking blood. This venom will paralyze people's nerves, so that mosquitoes will not be found in the process of sucking blood. However, it will be wrapped up afterwards, which is very itchy. Mosquito venom is acidic, and it doesn't feel itchy when washed with alkaline things. For example, there is also a saying that there is an acid-base balance in human blood, and human blood is weakly alkaline. When mosquitoes bite people, they should be injected into subcutaneous blood vessels first. This substance that prevents blood coagulation contains protein, and protein is a foreign body in human body, which destroys the acid-base balance of human blood, thus changing the viscosity of blood here, destroying the microcirculation of blood, causing small-scale blood coagulation and causing people's own immune response. If someone reacts strongly, it will swell into a small bag and feel itchy. It's not obvious if someone reacts weakly. After a few days, when the human blood reaches the acid-base balance again, the symptoms of bagging will disappear.
