So, what is the harm after mosquito bites? The greater the mosquito bag, the greater the toxicity? How to prevent bite by mosquitoes?

Come and learn together today ...

What is the harm after mosquito bites?

There are two types of mosquito lethality:

The first is to absorb blood and the harm is lighter.

Many people will have allergies, redness and pain, itching and unbearable local skin after being bitten by mosquitoes, redness and pain, itching, and serious situations such as cracking infection after scratching the skin.

The second is to spread fatal diseases and heavy lethality.

Mosquitoes first ranked first among the 15 most deadly animals to humans, and the number of human harm to humans exceeds the sum of the number of other animals in the rankings each year.

There are three genera that are closely related to human health, that is, the genus Mosquito (family mosquito), a mosquito (genus of malaria), and the genus Iraq (black spot mosquito) in my country. Essence

When mosquitoes absorb human blood, different categories of mosquitoes can cause different diseases and clinical characteristics.

Generally, malaria is mainly transmitted by mosquito, and clinical characteristics are manifested as the body's fever, sweating, and intermittent chilling; the clinical characteristics of the mosquito by bite human transmission are unclear consciousness and high fever in the body; It can spread a variety of diseases, such as dengue fever, yellow fever, and Kidon Kenya disease, which are the mosquitoes.

The greater the mosquito bag, the greater the toxicity?

After being bitten by a mosquito, the mosquito wrapped in the body is closely related to the strength of the personal immune system mechanism, which has nothing to do with the toxicity of the mosquito.

After being bitten by people with a strong immune system, they can be unscathed after being bitten, but most people have physical reactions, mildly show raised mosquito bags, and have obvious itching sensations. The skin lesions are manifested as erythema, pimples, wind masses and other symptoms. Essence

For those with weak immune systems, especially those with sensitive constitutions, after being taken blood, a large number of histamine and cytokines will be released, and they will appear in the future. If the reaction is fierce, it takes a long time to completely alleviate it.

In addition, scratching by hand will increase the release of organic nitrogen -moisturizing compounds, resulting in tissue damage or inflammation, resulting in local tissue edema.

When it feels itching, you can apply mint paste and flower dew water in time to relieve it instead of choosing to scratch.

What kind of blood does mosquito prefer? It is related to blood type, blood sweetness ...?

Mosquitoes are very sensitive to factors such as CO2, calories, volatile chemicals, etc., and their sense of smell can quickly detect and accurately locate these substances. The secretion of these substances is closely related to individual metabolism, such as urea, lactic acid, fatty acids, etc. of the body's metabolism products, etc. Therefore, when your CO2 emissions are large, sweat secretion is frequent, and the body's metabolism is strong, it is easier to get the favor of mosquitoes.

Mosquitoes, mainly through the smell in the air to identify the object of vampire, so whether the mosquito is not directly associated with the blood type.

Is it useful for mosquito bags?

Answer: useful -psychological effect, mainly using human pain to transfer.

Imagine that with nails on the mosquito bag, the subconscious will feel pain, and it will not feel itchy. In fact, the itching feeling does not disappear, but the pain is too itchy. It is completely my own psychological role Essence

Correctly handle the tips:

① When itching, it can be neutralized by alkaline substances, such as baking soda, soapy water at home, and itching effect is very good.

In addition, the use of salt water can be softened to soften the masses and can achieve pain relief and itching effect.

② Do not scratch your hands, especially at the skin of the skin, otherwise tissue damage will cause infection.

Because ticking may speed up the blood flow in the capillaries, at this time, some flower dew water can be sprayed in a small range. Most of the flower dew water contains alcohol. Large -scale use will experience alcohol allergies. Pain, should be discontinued immediately and seek medical treatment.

③ For mosquito bags on the skin, cold compresses can be used to relieve pain, such as wrapped frozen drinks with towels floating on the affected area. Drugs are always prepared in the home such as Di Narid cream and Ailoson cream.

④ When the mosquito bite appears red and swollen, first apply the ice cubes, and then use external drugs according to the doctor's order, such as 1%mint calamine washing agent or 1%mint cream.

⑤ When the bite is obviously infected, it is necessary to use anti -infective treatment drugs in time, such as Mapiro Star Ointment. If it cannot be relieved, medical treatment will be treated in time.

How to avoid being bitten by mosquitoes outdoors?

Remember the three words "avoiding, driven, destroying".

1 — avoid

Choose as light and light -colored trousers and long sleeves as outdoor activities to avoid grass, shade, warehouses, water edges, dark places, while avoiding dark clothing, keeping skin clean and non -stickiness, and the exposure of the body when the body is exposed in the wild.

2 —— drive

Choose a dew and mosquito repellent liquid containing the ingredients of Miramine and Irinin. When using mosquito repellent products, the "quantity" of the medicine is not as good as possible. You can choose a small amount for multiple times during outdoor activities.

Mosquitoes are scared of light. If it is outdoor activities at night, it should be taken with lighting equipment to avoid.3 ——

Because mosquito eggs, larvae, and pupae live in water, their growth and development cannot be separated from the water, so blocking the breeding and reproduction of mosquito from the source, the use of chrysanthemum exterior mosquito extinguishing agents to keep the ground clean and no water, do a good job of doing wellEnvironmental sanitation, trying to clear its own places and strengthen the natural enemy of mosquitoes, such as bats, swallows, dragonflies, spiders, gecko, frogs, etc., let them eliminate mosquitoes, use biological control to avoid environmental pollution.
