I was bitten by a mosquito-like bug when I traveled to Sichuan, and now I am still itching for a month.

1. Studies on the causes of biting show that mosquitoes bite people selectively, and those who can bring mosquitoes rich cholesterol and vitamin B are most favored by mosquitoes. Mosquitoes use smell to find the object that suits their appetite best from the crowd. Cholesterol and vitamin B are essential nutrients for the survival of annoying insects such as mosquitoes, which they cannot produce by themselves. Mosquitoes have a strong sense of smell. When humans exhale carbon dioxide and other smells, these smells will spread in the air, and these smells are like the bell for dinner, telling mosquitoes that a good meal is just around the corner. When a mosquito tracks its target, it always twists and turns with the smell of human breath until it touches the target, then it falls on the skin to patiently find a "breakthrough", and finally it directly inserts the "needle tube" into the skin to suck blood for 8-1 seconds. Second, the following kinds of people are easy to attract mosquitoes: First, people with developed sweat glands and high body temperature. Second, people who are tired or breathe faster. Third, people who like to wear dark clothes. Fourth, people with fast metabolism. Fifth, people who have made up. Sixth, pregnant women. Seventh, people who drink.

Sweat a lot in hot weather, so wipe off the sweat with paper towels and handkerchiefs in time. 2. If there are many mosquitoes in the daily activities, you should wear long-sleeved clothes. This is not because mosquitoes can't stick their needles in to suck blood because of the extra layer of cloth. In fact, the mosquito's mouth needle is very sharp, even cowhide and thick jeans can penetrate, and the clothes worn in summer are simply unbearable. The function of clothes is mainly used to cover the smell of skin secretions such as sweat, so that mosquitoes can't track it. 3. It is best to wear white clothes for outdoor sports, because white clothes have strong reflective ability and have the effect of driving away Aedes mosquitoes. Don't wear socks because you are too hot in summer, which will make the smell of sweat evaporate quickly and attract mosquitoes to attack other parts of the human body. Wearing socks with good sweat absorption effect can not only effectively reduce skin humidity, but also cover the smell. 5. It's not advisable to use strong-smelling cosmetics such as perfume when going to places where there are many mosquitoes. Fourth, take the following measures to relieve itching: 1.

At this time, alkaline substances can be used to relieve itching, for example, ammonia water can be used to relieve itching, and soap can also be dipped in water to smear on the redness, which can relieve itching within a few minutes. 2.
