Even mosquitoes know that mosquitoes are extremely harmful insects. They not only bite a person, which is already unpleasant, but their bites also cause severe itching, which, by the way, can worry more than one day. And sometimes the consequence is the strongest allergic reaction. Why mosquito bites are itching and what to do to cope with this problem - this is what I want to understand right now.
Why does a gnat have human blood?
You have to start from the main thing. But still, before delving into the theory of why mosquito bites are itching, it must be said that in fact it is an insect and does not bite. It only drinks human blood. Bite, or rather bite, the skin of an insect is needed in order to achieve its goal of mosquito.
Blood is mandatory first of all to females. So, the amino acids that are in its composition, give individuals strength and ability to put up to one hundred eggs of offspring at a time. A hungry female egg can also be put off, but only one. That is why, following the instinct, mosquitoes go in search of their victims, carriers of such valuable and useful blood for them.
How the victim is defined
Why is the mosquito bite? We will deal with this a little later. Now I want to understand how these insects find people. Thus, a certain fraction of a substance, such as isoleucine, is contained in a person's blood. This is exactly what females need to reproduce. This substance, by the way, is larger in large animals. And it is them that mosquitoes prefer first of all. But if there is no alternative, they agree to a lower-quality - human blood. They find their victims by the heat radiated by the body, sharp movements, and also by smells (primarily on the fragrance of sweat).
About the mosquito bite process
It's time to figure out why mosquito bites itch. But to understand this, you need to know the whole process of action of an insect. So, the female does not immediately sits down on the man. She some time looks after itself the best place for a bite. After landing, it can also slightly move around the body, choosing the soft phase, that is the place that will be easier to pierce with their proboscis. Then with the help of this occurs on puncture of the skin. At the same time through the proboscis into the wound saliva of the mosquito. This prevents the blood clotting, giving the female the opportunity to feast on this human biological fluid enough to meet their needs.
About unpleasant sensations
But why are mosquito bites itchy? This question is often asked by people to each other. The thing is that the saliva of this insect contains proteins that, when ingested into the human body, cause itching, swelling of the bite and other unpleasant sensations. Histamine, which is also injected under the skin, triggers immune processes that often lead to an allergic reaction to a mosquito bite. It causes the abovementioned pruritus, swelling and redness.
An interesting feature
So, we understood why the mosquito bite is scratched. This is due to the special composition of the saliva of the insect. But it must also be said that the more a person bites mosquitoes, the sooner the body adapts to it. That is, those people who are more often bitten by mosquitoes, less often there are various unpleasant sensations, such as itching or swelling. All because the body gets used to the proteins of the saliva of females and no longer reacts to them as foreign elements.
On the dangers of mosquito bites
Why is the mosquito bite? Because at the moment of contact with a person, the insect injects under his skin a little of his saliva. And this is fraught with negative consequences. After all, as already mentioned above, mosquitoes also feed on the blood of animals, including rat. These animals, in turn, can be carriers of a variety of infections. That is, it turns out that a mosquito can easily become a so-called transmitter of diseases from animals to humans. This is the most important danger. Doctors also say that mosquitoes can tolerate infections such as encephalitis, malaria, certain types of fever, and elephantiasis.
What to do? How to be saved?
Knowing why a mosquito bite itches, you can try to protect themselves from the attack of these nasty insects. Thus, modern scientists have invented many different ways. It's different sprays, ointments, creams and lotions, after which around the human body is formed something like a shield. To pierce his insects for certain reasons can't.
How to relieve uncomfortable sensations
We now know why mosquitoes bite and why their bites are itching. But you also need to tell about how you can calm down unpleasant sensations in the event that this insect has already bitten.
- To prevent swelling and itching, ice or cold can be applied to the bite site.
- It is possible to soothe the itch by a concentrated solution of soda and water.
- You can also treat the bite site with a solution of boric acid or a lemon.
- Help to cope with itching vodka, vinegar or cologne, which need to handle the lesion on the skin.
Well, the main thing about which you need to remember: you can not comb the place of bite, because unpleasant sensations from this will only increase.
