According to medical statistics, in the past 30 years, lung cancer in our country.
The incidence has increased by 465% and it has gone to replace liver cancer.
It is the number one cause of death due to cancer.
In people over 80 years of age, lung infections are the number one cause of death, while in people over 90 years of age, lung infections can account for half of all deaths.
Lung infection, as the name suggests, is when bacteria from the outside world enter our lungs and cause an infection. So where in life could there be such bacteria?
In fact, in our water pipes, there is a type called Legionella.
of bacteria. It got its name because in the 70s there was a group of veterans who stayed in a hotel at the same time, and the veterans contracted the bacteria on the same day. After it enters our body, it multiplies, eventually leading to the occurrence of severe inflammation and even death.
This bacterium often attaches to our water pipes, and when we turn on the faucet, it will come out with the water, and when we open the faucet too much, it will also disperse into the air with the sprayed water, and if we inhale these bacteria at this time, it may cause infection. But this bacterium has a peculiarity, which is that it will be killed in 100 degrees of water, so we can kill this bacterium by boiling water. That's why we don't recommend drinking raw water.
In the United States, the incidence and number of diseases caused by this Legionella bacteria far exceed that of our country, one of the reasons is that we Chinese like to drink hot water, and they like to drink cold water. In addition, this bacterium can also grow in the condensate of the air conditioner in our home, so this reminds us to clean the air conditioner regularly. This bacterium can also be found in external areas such as fountains or in our hot springs, which can invade our bodies and cause diseases.
In addition to the legionella we mentioned, there are also some bacteria that we will be exposed to in our lives.
In order to improve the greenery of our houses, many people have cultivated plants at home, and with the arrival of autumn and winter, the fallen leaves will also increase. It is often said that these are also placed in the pots of plants as nutrients. In fact, it is precisely this process that causes a species called mucormycetes.
of hyperplasia. The humid and warm environment in the pot creates a good environment for bacteria to grow.
So when we come into contact with these bacteria while sorting these flowers and plants, if they invade our lungs, it can cause infection. Therefore, it is best for everyone to do a good job of protection when tidying up. In fact, in addition to flower pots, many old clothes, old newspapers, and even some old houses will have this kind of mold in our lives.
It's a good idea to wear a mask and gloves to prevent germs from attacking.
Many actions in life have their scientific basis, such as drinking boiled water and opening windows frequently for ventilation, which can help us reduce the chance of getting sick, because the occurrence of illness is not sudden, but caused by these or those carelessness in life.
Finally, if you feel cancer.
It is not preventable, so I suggest you take a look at the following column, 16 types of cancer have a way to prevent:
-
In the lungs of the human body, if there are too many bacteria, it can lead to lung infections. However, normally our lungs have an epidemic prevention system, so we usually do not get infected.
-
Inhaled through the nostrils, there are a lot of nose hairs in the nostrils, and the eyelashes can filter out the bacteria, and then enter the lungs, which undergo a filtration process.
-
Bacteria enter our lungs with our breathing.
A moderate amount of bacteria can enhance the lungs' ability to prevent the virus. If you breathe in too many bacteria, it can make us sick.

The bacteria were first discovered by the Dutchman Antonie van Leeuwemhoek (1632-1723) on the tartar of an elderly man who had never brushed his teeth, but it was thought to be a natural occurrence.
It wasn't until later that Pasteur pointed out with a gooseneck flask experiment that bacteria are produced by bacteria already in the air, rather than producing stuffy babies on their own, and invented the "pasteurization method", which was hailed as the "father of microorganisms" by later generations. Noisy and sleepy.
The term bacteria was first coined by the German scientist Christian Gottfried Ehrenberg (1795-1876) in 1828 to refer to a certain type of bacteria, and the word ** means "little stick" in Greek.

After about two breaths, a bacterium entered the nasal passage.
In recent years, air pollution has been severe, and the amount of microorganisms in the air has also increased, but the number of microorganisms varies greatly depending on the environment. The index of air pollution is 1000 m, and in cities that are not polluted by air, the maximum microbial content in the air of 1m (1000L) is 1000, and the intake volume of a person is about 500ml (
Therefore, in the air that is not polluted, you can inhale at most one bacteria in one breath, that is, you can inhale at most one bacteria in two breaths.
In the process of respiration, whether bacteria can be killed or not is a process of "game" between the respiratory tract and bacteria, and whether bacteria can colonize respiratory tract infections.
or be removed, depending on the individual's physical condition.

The reason why there are bacteria in the air is because the bacteria are small in size and light in weight, and they are easily suspended in the air, and because the air contains a lot of particles, bacteria often combine with particles to form bubbles, which can absorb water and nutrients from the suspended particles in the air, so that bacteria can survive for a long time. Regarding whether there are bacteria in the vacuum, this question is very obvious, there is definitely no (of course, this problem is only limited to the creatures on the earth, it should be the creatures of outer space, we don't know how amazing the creatures are), it is very simple that any organism has osmotic pressure and internal pressure, as well as the appropriate survival temperature, if it is a vacuum state, it will not be able to maintain internal pressure, and the temperature is likely to drop to a state where the organism cannot survive, resulting in the leakage of the contents and the cessation of metabolism to death, simply put, it is like you put people in a container, Then start vacuuming, no doubt that the person will burst from the content department is a truth, or throw a person into a bottle of liquid nitrogen, haha, what a bloody example! Of course, if the scope reaches the universe, it is difficult to say, after all, astronauts can spacewalk by relying on spacesuits, and who can guarantee that there is no creature in the magical nature that has evolved a structure similar to that of a spacesuit, so it is really difficult to say whether there are bacteria in the universe, and it is very likely that it cannot be called bacteria.
Depending on the Earth's environment, bacteria need nutrients, temperature, stress, and so on to be able to stock them!

-
Yes, bacilli, pigment-producing bacteria and fungal spores are common in outdoor air; Overall, there are more microorganisms in indoor air than outdoors.
-
There is air in ordinary air, but there is no air in the ultra-clean table that has been filtered and sterilized.
-
Do you know how much dust there is in the air?
It's easy to rub against the air, and it can be charged so that small things like bacteria can be attached to it, and the air is not dry in most places, so bacteria can survive for a long time.
The vast majority of bacteria are not pathogenic!
If a small number of pathogenic bacteria want to enter the human body, they must also penetrate ** (break the mouth), or enter from the respiratory tract, oral cavity and other places.
**There are hair on the surface, nasal hair in the nasal cavity, which has a mechanical cleaning effect; At the same time, sebaceous glands, sweat glands, and oral salivary gland secretions have a certain bactericidal and removal effect; Oral cavity and body surface symbiotic bacteria have a certain antagonistic effect on foreign bacteria.
If the first line of defense is blocked, the human body will not react at all. Even if it is broken, there is a second line of defense, mainly lysozyme in body fluids, etc., as well as phagocytic cells. When the second line of defense is activated, there will be mild symptoms, such as local redness and swelling.
The second line of defense cannot be prevented, and when the third line of defense [Specific Immunity] is activated, it is possible to have significant illness at this time!

Analysis: Hello, there are a lot of bacteria in the air, so as long as your place is not bad, you should not be infected.
Guidance: Usually strengthen physical fitness, functional exercise, enhance physical fitness, and then eat more high-protein and high-calorie food. Take a protective measure.

Yes, there are a lot of invisible bacteria in the air. And our body has a lot of anti-virus systems that can effectively filter these bacteria (and wear a mask).
-
There are really a lot of bacteria in the air.

Bacteria do not necessarily need air, some bacteria need air to survive, but some bacteria do not need air, such as anaerobic bacteria, which is a kind of bacteria that grows better in an aerobic environment than in an aerobic environment.
Bacteria are widely distributed in soil and water, and some bacteria live in symbiosis with other organisms, and the bacteria are very small, and the smallest bacteria are only microns long, so most of them can be seen under a microscope.
Bacteria are generally unicellular and have a simple cell structure that lacks a nucleus, cytoskeleton, and membranous organelles, such as mitochondria and chloroplasts, because of these characteristics, so bacteria are prokaryotes.
Some bacteria are pathogenic bacteria, however, most types of bacteria are not pathogenic and are very useful, most bacteria are decomposers, and some bacteria are consumers and producers.
1. Bacteria are widely distributed in nature, and there are a large number of bacteria in the air, soil, water, human body surface and pipelines that communicate with the outside world (such as respiratory tract, digestive tract, and genitourinary tract)! >>>More
Watermelon is a great fruit to cool off in summer, especially chilled watermelon, which quenches thirst and cools down. The reason why watermelon is very popular with everyone is mainly because watermelon has more water and tastes sweeter. >>>More
A superbug is a drug-resistant bacterium that can cause sores and blisters in people, and even gradually make people die of muscles. What's even more terrifying is that antibiotic drugs don't work against it, and the patient will have terrible inflammation due to the infection, high fever, convulsions, coma and finally death. The terrible thing about this germ is not its lethality to people, but its resistance to ordinary bactericidal drugs - antibiotics, for which people have almost no medicine. >>>More
Yes. If the refrigerator is used for a long time, a large number of bacteria will be parasitic due to the spoilage of food scraps. If the refrigerator has a UV disinfection lamp, it is recommended to open it frequently for disinfection. >>>More
Some nitrifying bacteria are added directly to the filter media, such as filter cotton, activated carbon, and porcelain rings are added. If you open the cylinder as new, pay attention to oxygenation.
