Summer Wars: Say goodbye to the "buzzing" troubles, here are the mosquito repellent tips!

◆Why are mosquitoes so rampant in this hot summer?

The temperature is high in summer, mosquitoes grow faster and the density is higher, which is one of the reasons why mosquitoes are rampant in summer. In addition, mosquitoes lay eggs and reproduce in water. In summer, there is abundant rain, which easily produces various stagnant water, which also provides a breeding environment for the growth of mosquitoes. Some people say that type B blood is more likely to attract mosquitoes. Is the "blood type theory" about mosquitoes true?

Fake! What attracts mosquitoes is not blood type but smell. Mosquitoes prefer people who sweat easily and love to wear perfume, not people with a certain blood type as everyone thinks.

Of course, mosquitoes also like to track people who have high carbon dioxide emissions and high metabolism. This is because mosquitoes can easily perceive this human information, which is very attractive to mosquitoes and facilitates their directional tracking. In addition, mosquitoes also like people who wear dark clothes. Mosquitoes like to suck blood in low light conditions, so mosquitoes are most likely to "buzz" around your ears at night. During the day, people wearing dark clothes have a weaker ability to reflect light, which happens to cater to their preferences. For the same reason, mosquitoes are more likely to bite people with darker and redder skin.

◆What should I do if I get bitten by a mosquito?

When mosquitoes suck human blood, they also inject their "saliva" into the skin. This "saliva" can prevent blood from clotting, thus ensuring that the mosquito can suck blood smoothly. However, this "saliva" can also trigger a local immune response in the human skin. This reaction causes tissue fluid to leak out, which helps transport immune components (such as antibodies and white blood cells) to the affected area to resist foreign substances and potential pathogens brought by the "saliva". Due to individual differences, people have different degrees of immune response to mosquito bites. Common reactions are skin itching and rashes. Excessive scratching will stimulate the continuous secretion of histamine, making people feel more and more itchy, which may lead to secondary infection, pustules, and even allergic reactions, which are more serious.

So how can you stop itching quickly? One word: endure! According to relevant experimental results, if you do not scratch after being bitten by a mosquito, the itching will gradually decrease with the extension of time, and it will almost stop itching in about an hour. If the itching is really unbearable, you can apply wind oil, cooling oil, etc. to stop itching. If the reaction is serious, you should go to the hospital dermatology department for treatment in time.

◆Tips for preventing and killing mosquitoes at home

Install screen doors and windows, and repair damaged areas in time to prevent mosquitoes from entering the house; if there are mosquitoes at home, use mosquito coils (discs, electric heating sheets, electric heating liquids), aerosols and other sanitary insecticides to kill them in time; hang mosquito nets when sleeping at night to avoid mosquito bites; regularly clear all kinds of stagnant water in sewers, awnings, flower pot trays, bonsai, abandoned fish tanks, etc., and clean up garbage, as even small eggshells can become breeding grounds for mosquito larvae; try to avoid the peak activity period of mosquitoes when doing outdoor activities, wear long sleeves and long pants when going out, or apply mosquito repellent on exposed skin for protection.
