Mosquitoes don't distinguish between human blood types. However, as we feel, mosquito bites do have a preference. What mosquitoes want is not blood, but sugary substances.
What blood group attracts mosquitoes most
For a long time, people have been debating why some people are more vulnerable to mosquitoes. In fact, mosquitoes do not distinguish between human blood types. However, as we feel, mosquito bites do have a preference. What mosquitoes want to eat is not blood, but sugary substances. Mosquitoes (female mosquitoes to be exact) bite people, but they want to improve their fecundity. Because human blood contains substances that ripen mosquito eggs. If your blood is rich in cholesterol or vitamin B, female mosquitoes prefer you. The 'chemoreceptor' on its tentacles is the tool to find you.
There is a relationship between blood type and disease. Russian medical experts have found many evidence of the correlation between blood type and disease. Experts believe that people with type O blood generally live longer; People with type a blood have little immunity to smallpox, and mosquitoes love to bite them; People with type B blood rarely get cancer; People with AB blood have high body immunity.
What kind of people do mosquitoes like to bite
Mosquitoes like people with developed sweat glands and high body temperature.
For people who like to sweat, the acidity in the blood is enhanced, and the sweat discharged makes the body surface lactic acid value higher, which is attractive to mosquitoes. In addition, there is a heat receiver in the antennae of mosquitoes. It is very sensitive to temperature. As long as there is a slight change in temperature difference, it can be immediately observed that sweating people's body dissipates heat quickly and will also be attractive to mosquitoes.
Mosquitoes like people in dark clothes.
Because black is the first choice for mosquitoes to attack, such as Aedes (also known as flower mosquitoes), they like to stop on black clothes. The second is blue, red and green. Mosquitoes don't like to bite people in white. Similarly, mosquitoes love to bite people with darker or redder skin.
Mosquitoes like people who are tired or breathe faster.
Mosquitoes look for prey by smell. Carbon dioxide has a strong attraction to mosquitoes. Mosquitoes have carbon dioxide receptors on their small tentacles, which can sense carbon dioxide, lactic acid and other substances. Mosquitoes can detect the carbon dioxide emitted by human exhalation 15 meters away.
After exercise or physical labor, people's breathing will speed up. At this time, more carbon dioxide will be exhaled. The carbon dioxide gas will form a moist and warm airflow about 1 meter above the head. Mosquitoes are sensitive to this and will smell it. Similarly, people with large lung capacity or fast breathing rhythm exhale more carbon dioxide, and mosquitoes swarm after smelling it.
Mosquitoes like pregnant women
Pregnant women are particularly vulnerable to mosquitoes. A medical study in the United States shows that pregnant women are particularly attracted to mosquitoes, and their chances of being bitten by mosquitoes are twice as high as other women.
Mosquitoes like people with fast metabolism
Generally speaking, men are more attracted to mosquitoes than women, young people are more attracted to mosquitoes than the elderly, and healthy people are more attracted to mosquitoes than patients, because there are more secretions on the surface of the skin. When women are on holiday, their secretions change and attract mosquitoes more. Mosquitoes have a 'feeding tendency', which is not what people think that some people have delicate skin and sweet blood to provoke mosquitoes. The main reason is that some of their breath attracts mosquitoes.
How does mosquito bite detumescence
Wipe toothpaste.
Just dip a little water with toothpaste and wipe it evenly on the bag. However, we should pay attention to the choice of toothpaste. Those with strong anti-inflammatory effect and strong alkalinity will have better effects!
Apply garlic slices.
Apply sliced garlic repeatedly on the bitten place by mosquitoes for several minutes, which has obvious analgesic, itching and anti-inflammatory effect. Even if the bitten place has become a big bag or is inflamed and ulcerated, you can wipe it with garlic. Generally, it can reduce inflammation and swelling after 12 hours, and the ulcerated wound can be cured after 24 hours. People with skin allergy should use it with caution.
Apply washing powder.
After being bitten by poisonous mosquitoes, the human body is not only swollen and itchy, but also unbearable. Wash the bitten place with clean water, do not wipe it all dry, and then apply a wet finger with a little washing powder on the bitten place, which can immediately stop itching and the swelling will disappear soon. After the swelling disappears, wash the washing powder with clean water.
soap.
Because being bitten by poisonous mosquitoes will have a kind of venom, which is acidic, alkaline soaping is also very effective. After washing with alkaline soap, pay attention not to scratch with your hands at ordinary times. It will be fine soon.
Correct mosquito repellent methods
1. Take a bath as soon as possible after exercise to keep your skin fresh. It's hot and sweaty. Wipe off the sweat with paper towels and handkerchiefs in time.
2. If there are many mosquitoes in the place of daily activities, wear long sleeved clothes. It's not because there are more layers of cloth on the body, so mosquitoes can't go in with mouth needles to suck blood. In fact, the mosquito's mouth needle is very sharp, even cow leather and thick jeans can penetrate, and the clothes worn in summer can't bear a 'bite'. The function of clothes is mainly to cover the smell of skin secretions such as sweat, so that mosquitoes can't track them.
3. It's best to wear white clothes for outdoor sports, because white clothes have strong reflective ability and have the effect of driving away Aedes.
4. Don't wear socks because it's too hot in summer. This will quickly volatilize the smell of sweat 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 mask the smell.
5, to mosquitoes and many places should not use perfume and other strong smell of cosmetics.
6. Soap silk + washing powder water. Place a basin in the house. Add some water mixed with soap silk and washing powder in the basin. The next day, there will be some dead mosquitoes in the basin. If you continue to use this method every day, you can hardly spray insecticidal liquid to kill mosquitoes. Moreover, there will be fewer and fewer mosquitoes.
7. Plant mosquito control is more environmentally friendly and effective. Flowers such as dried oranges or roses can be placed in the room to expel mosquitoes.
8. More efficient mosquito control: use electric mosquito repellent incense sheet or electric mosquito repellent incense liquid. Scientific and efficient, but pay attention to the side effects and effects of the product.
