As the saying goes: All things have spirits, except mosquitoes.
In the blink of an eye, summer has arrived, and the most annoying little animals have arrived.
Not only has it been harassed and unable to sleep, but it has even left us with a deep "kiss", taking away our blood at the same time, but also leaving us with a deep "kiss mark".
But did you know?
----- mosquitoes are the creatures that kill the most humans.
Why does a small mosquito have such a big "ability"?
According to the data, there are currently about 3,000 kinds of mosquitoes in the world, of which only 80 kinds of bite humans, mainly Anopheles, Aedes mosquitoes and Culex mosquitoes.
And the reproduction rate of mosquitoes is extremely fast, a mosquito can produce hundreds of eggs at a time, and its larvae can live in places where there is almost no water.
Because of their high fecundity, mosquitoes are now a serious global public health problem, and few insects can match the threat posed by mosquitoes to humans.
The biggest threat of mosquitoes is the transmission of diseases, and it can be confirmed that there are more than 80 kinds of diseases transmitted by mosquitoes, the most common of which are malaria, yellow fever, dengue fever, Japanese encephalitis and so on.
According to statistics, about 700 million people in the world are infected with various diseases due to mosquito transmission every year, and 1 in every 17 people dies.
Obviously in the same room, why am I the only one who is so deeply "attached" to mosquitoes?
We've all been bitten by mosquitoes, but sometimes we wonder why ---- are in the same room, some people are bitten by mosquitoes to "scales all over the body", while others are unscathed?
In fact, it is mainly mosquitoes that usually travel long distances through carbon dioxide gas to find the object of the bite. Also because of the smell based on carbon dioxide, mosquitoes can lock on to targets at a distance of about 50 meters.
If the body sends a stronger "signal" to the mosquito, the greater the chance of being bitten by the mosquito.
Some people have found that mosquitoes have a very strong sense of smell through research, and when the carbon dioxide exhaled by humans or the odor emitted from the body is more obvious, it may attract mosquitoes and become the target of mosquito attack.
Who do mosquitoes like to bite?
1. People who sweat often
Because the summer temperature is particularly high, it is easy to cause the body to sweat frequently, but for some people who are particularly prone to sweating, it is easy to cause a sour smell on the skin and clothes.
If from a physiological point of view, people who often sweat will have more acidic substances in their blood, so it will lead to an increase in the lactic acid value on the skin, and mosquitoes are particularly sensitive to this smell, so they like to bite such people.
2. People with fast breathing rate
People with a fast breathing rate also exhale a particularly high amount of carbon dioxide.
The antennae of mosquitoes are very sensitive to carbon dioxide and can be detected at about 15 meters away, so they will fly to such people non-stop and then find opportunities to bite people with fast breathing rates.
3. People who wear dark clothes
Mosquitoes have a habit of darkening, so in the summer, they like to wear darker colors, such as blue, red, green and other colors, it is easy to attract the attention of mosquitoes, which will increase the probability of being bitten by mosquitoes.
In addition, people with darker skin will often be bitten by mosquitoes, while women with whiter skin will have a much lower chance of being bitten by mosquitoes.
4, people with fast metabolism
People with fast metabolism are more likely to be bitten by mosquitoes, because fast metabolism means that the body is relatively healthy, and mosquitoes are particularly interested in healthy people, so they will constantly harass and bite such people.
For women, the elderly and patients, the probability of being bitten by mosquitoes will also be greatly reduced due to the relatively slow rate of metabolism.
Fat people are more likely to be bitten by mosquitoes?
As mentioned above, people who exhale more carbon dioxide, sweat often, and have a faster metabolism are more likely to be liked by mosquitoes.
Usually fat people are more likely to meet the above three points, so they are more likely to be "attacked" by mosquitoes.
Therefore, small mosquitoes pose such a great threat to human health.
Although some diseases can be prevented and treated through vaccines or drugs, the most important prevention and treatment method is still to prevent mosquitoes, kill mosquitoes, and cut off all transmission routes.
