It's very hot. What if there are more and more mosquitoes?

Cause of biting

In fact, male mosquitoes do not suck blood, but only plant juice, so they generally do not enter the house. Only when it gets cold in autumn will it run indoors to avoid the cold. Blood-sucking mosquitoes are all females. Blood-sucking is to increase nutrition and reproduce. When they are full, they will find a place with water to lay their eggs.

Mosquitoes generally start to go out in May and reach the peak in the middle and late August. When the climate gets cold in autumn and the temperature drops below 10 degrees Celsius, it will stop breeding, go into hibernation without eating, and come out after waking up the next spring. My favorite temperature is about 30 degrees Celsius, which is unbearable. Their living and breeding environment must have water, so mosquitoes often breed in groundwater, sewers and other places. Mosquitoes choose their targets by smell.

Scientists' research shows that mosquitoes bite people selectively, and those who can bring mosquitoes rich cholesterol and vitamin B are most favored by mosquitoes. Mosquitoes use their sense of 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, and they cannot produce these substances by themselves.

Mosquitoes have a strong sense of smell. When humans exhale carbon dioxide and other smells, these smells will spread in the air. These smells are like the bell for dinner, telling mosquitoes that a good meal is just around the corner. When a mosquito tracks a target, it always twists and turns with the smell of people's breath until it touches the target and then falls on the skin, patiently looking for a "breakthrough". Finally, directly insert the "needle tube" into the skin to suck blood for 8- 10 seconds.

Mosquitoes do have this "food preference". This is not because some people think that their skin is tender and their blood is sweet, which attracts mosquitoes. The main reason is that some of their breaths attract mosquitoes. Generally speaking,

The following kinds of people and mosquitoes will have a soft spot for them:

First, people with developed sweat glands and high body temperature. People who like sweating, the acidity in the blood is enhanced, and the discharged sweat makes the lactic acid value on the body surface higher, which is attractive to mosquitoes. In addition, mosquitoes have a heated body in their antennae, which is very sensitive to temperature. As long as the temperature difference changes a little, it can be detected immediately. People who sweat lose heat quickly and attract mosquitoes.

Second, people who are tired or breathing faster. People will breathe faster after engaging in sports or manual labor. Some people have larger lung capacity or faster breathing rhythm. In this way, the exhaled carbon dioxide is more, and the carbon dioxide gas will form a moist and warm airflow at the height of 1 m above the head. Mosquitoes are sensitive to this and will smell it.

This shows that your body is overwhelmed, so you should go home and rest immediately, and don't overdraw your physical strength, so as not to cause more problems.

Third, people who like to wear dark clothes. Mosquitoes don't sleep during the day and go out at night, mainly because they have the habit of dark. If they wear dark clothes, they will have a black shadow at night, and mosquitoes will chase them to darker places. The color of clothes, such as black, is the first choice for mosquitoes to attack, followed by blue, red and green. Mosquitoes don't like to bite white. Similarly, mosquitoes like to bite people with dark skin or red skin.

Fourth, people with fast metabolism. So children are easily bitten by mosquitoes, while old people are just the opposite.

Fifth, people who have made up. In order to verify the allure of smell to mosquitoes, American scientists tested and analyzed more than 3,900 substances with olfactory instruments. It is found that hair gel, hand cream, facial cleanser and other cosmetics are very attractive to mosquitoes. Most cosmetics contain stearic acid (a fatty acid), so people who wear makeup are more favored by mosquitoes than those who don't wear makeup.

Of course, there are also some smells that mosquitoes hate. The smell of bay leaves, lemongrass oil, citronella, garlic and geraniol will keep mosquitoes away.

Sixth, pregnant women. Pregnant women are particularly prone to attract mosquitoes. A medical study in the United States shows that pregnant women are particularly attracted to mosquitoes, and the probability of being bitten by mosquitoes is twice that of other women.

Seventh, people who drink. People are also easily bitten by mosquitoes after drinking alcohol, eating beef and mutton or taking antihypertensive drugs.

How to refuse "red envelopes"

1. Take a bath as soon as possible after exercise to keep your skin fresh. It's hot and sweaty, so wipe off the sweat with paper towels and handkerchiefs in time.

2. If there are many mosquitoes in daily activities, wear long-sleeved clothes. This is not because mosquitoes can't stick needles in it to suck blood with an extra layer of cloth. In fact, the needles of mosquitoes are very sharp, even cowhide and thick jeans can penetrate, and the clothes worn in summer are simply unbearable. The function of clothes is mainly to cover up 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 can drive away Aedes mosquitoes.

Don't wear socks because it is too hot in summer, which will make the 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 up odor.

5. It is not advisable to use irritating cosmetics such as perfume in places where there are many mosquitoes.

The following measures can be taken to relieve itching:

1. Most people will have symptoms such as redness, itching and pain after being bitten by mosquitoes. At this time, you can use alkaline substances to relieve itching, such as ammonia water, or you can use soap dipped in water to apply it to the redness and swelling, which will stop itching in a few minutes.
