Mosquitoes don’t like blood type O the most, but…

Summer is here,

While enjoying "small beer and small barbecue",

The season of love-hate relationship with mosquitoes has also arrived.

That puzzling question comes again.

Why do mosquitoes always bite me???

Are the "urban legends" about mosquitoes true?

"O-type blood is sweet and most likely to attract mosquitoes"

"Type A blood smells bad, mosquitoes don't like it"

I got bit by a mosquito

Grandma will immediately spit on it for you:

"It's for itching!"

When pinching mosquito bites, make sure to make a cross

To "seal"

but

Most of these statements...

There is no scientific basis

The "mosquito blood type theory" has no scientific basis

What influences mosquitoes to bite is not blood type but smell. Compared with identifying blood type, mosquitoes prefer cool guys wearing black clothes who sweat easily and love to wear perfume.

Why do mosquito bites itch?

This is because when mosquitoes bite people, they inject their "saliva" into our bodies.

When mosquito saliva containing anticoagulant and anesthetic ingredients is injected into the human body, the body will release histamine, causing mosquito bites to form on the skin surface and producing an itchy sensation.

It is true that the more you scratch a mosquito bite, the more it itches.

Scratching mosquito bites will stimulate the continuous secretion of histamine, making people more and more itchy.

Applying saliva to mosquito bites does not relieve the itching

99% of human saliva is water. Applying saliva to the saliva is almost the same as applying water. It has no real effect on relieving itching. (Tell grandma quickly)

Is it useful to pinch a mosquito bite in the shape of a cross?

Yes, but not completely. Pinching the cross-bun relies on the pain to suppress the itching, which is temporarily effective. However, if the skin is broken and infected, it is not worth it.

Who is the “walking meal” in the eyes of mosquitoes?

People who exhale a higher proportion of carbon dioxide are more likely to be spotted by mosquitoes, who can sense such people from 50 meters away;

People with a higher basal metabolic rate and more active metabolism sweat more and are more attractive to mosquitoes;

Drinking a lot of alcohol, especially beer, will cause your sweat to contain alcohol and acidic substances such as acetic acid formed by metabolism, which will also attract mosquitoes.

Pregnant women have a higher metabolic rate and exhale 20% more carbon dioxide than normal people, so they are more attractive to mosquitoes.

People who wear dark-colored clothes, such as black, purple, and bright red, are more likely to attract mosquitoes.

What is the most effective way to prevent mosquitoes?

Make a wish: May mosquitoes go away this summer!
