Why do rats bite sleeping people, and do rats bite sleeping people

When our human body is sleeping, the blood supply to the limbs will become relatively small, but the blood supply to our brain and heart is mainly guaranteed, so the temperature of the limbs is relatively low, including the peripheral circulation is relatively poor. In such a state, the temperature is relatively low, and rats will not eat anything alive. In this state, he thinks that we are dead, rotten, transgendered things, so he gnaws.

So we wonder why rats bite people who are asleep. The main reason is that we have a poor learning cycle. If we have a school body temperature at a temperature, or if we move the project, rats will not bite us.

Because they are as timid as a mouse.

Some say they eat everything, some say they can't kill anything, and some say they bite.

Today, I will give you a science popularization, those unknown facts about mice.

There are more than 480 species of rats in the world, some larger than dogs.

If the small house mouse already scares you, the next rat size may scare you.

The African giant rat can reach a body length of up to 1 meter, which is larger than some dogs, while the capybara, the largest rodent animal, is even larger than the African giant rat, which can reach a body length of more than 1 meter.

According to archaeologists, the rats that lived in the past were much larger than these animals, as can be seen from the extinct fossils of giant rodents, but thankfully, they are a thing of the past.

Have you ever seen a rat with a nursery bag?

The rat family is strange, but like kangaroos, it is rare to have a nursery bag.

Possums, which are mainly native to Latin America, have a very easily recognizable pocket that functions just like kangaroos.

The most distinctive feature of the possum is its "play dead stunt".

When in danger, it will feign dead, behaving in a very similar way to that of an "epileptic patient", convulsing incessantly, and if this does not deceive the predator, it will also secrete a foul-smelling yellow liquid that will make the predator more sure that it is a decomposed corpse, so as to escape.

It may be that the person who is asleep does not move for a long time, and the rat does not feel dangerous.

It is possible that there have been reports of rats biting sleeping people in the middle of the night.

On October 22, 2012, Qilu Evening News reported:I was sleeping at night, and my finger was bitten by a mouse. On the evening of October 19, 2012, Ms. Wang, who was working at a construction site, encountered such an incident.

Because vaccines were hard to find, Ms. Wang went to four hospitals.

On February 13, 2017, according to Anhui Business Daily, the reporter learned from the Provincial Consumer Protection Committee that during the Spring Festival, Mr. Zheng from Dongzhi County, Chizhou City, returned to his hometown to get married. In the meantime,When the bridesmaids were staying in the hotel, they were woken up by rats while sleeping.

The old man has some traditional concepts, you say he's right, you can't verify it, you say he's wrong, you can't say it's wrong, so this thing makes people very contradictoryFor example, the old man said that when he was dreaming, he was bitten by a mouse while sleeping, which is a very unlucky symbol, because in the eyes of the old man, the mouse is a representative of filth. <>

Personally, I think this situation is relatively unlucky, and it is not a particularly serious thing, such as being bitten by mosquitoes when you sleep, bitten by cockroaches and bitten by centipedes, it may be a special environment in which your home is located, if it is a normal settlement area, then basically the possibility of these mosquitoes appearing should be relatively small,Not to mention rats, he avoids people in the general activities of rats, and he may appear in people's homes, but he runs quickly after seeing people, and will not take the initiative to attack humans. <>

It is difficult to encounter these things in the modern people's home, if you live in a residential commercial house, then it is basically difficult for you to have rats in your home, because the house is built with a concrete structure, unlike the old house is a loess, lime and stone structure, the concrete structure is very strong, and the rat has no place at all, not to mention that your home is in more than a dozen floors, and the rat can't go up at all, so it is impossible for your home to touch these things, don't think so muchSome of these things were only rumored decades ago, and now basically no one knows about them. <>

Chinese culture has been inherited for thousands of years, and there are good places and bad places, so we must uphold an attitude to take its essence and remove its rough and really useful traditional virtues, we must pass it on, those feudal superstitions are unreliable, we must gradually abandon it, but the concepts held by the older generation, you can't absolutely deny himBecause he believes in this thing, he has believed it all his life, and you suddenly say that he is not right, do you think he can not quarrel with you? There is no need to quarrel about this kind of thing.
