I have long been tormented by the question, and that, in fact, is a cold? Where does it come? Man suffers from this disease, if it is, of course, the same disease, at least two times a year and find any interesting information about the disease, it is difficult on the internet. How can we think about the prevention or treatment of the disease, when it is difficult to understand even its essence? I will clarify, the word “cold”, I mean not the viral infection that can be picked up on public transport, supermarket, or anywhere else where there is a lot of people, including sneezing, a disease which befalls us when our body’s “studio”, that is cool. This mysterious disease can be picked up even during a hike in the woods when we are not in contact with any one person. But the infectious nature of the disease, indeed, for a group of diseases does not cause any doubts.
As the bacteria get to us
So, where does come from bacteria that cause colds? And they are to live in our bodies, in the mucous membranes of the respiratory tract. Just the growth of their number hinders our immune system, which works on these mucous membranes. Therefore, we see no signs of a cold. It happens, you can say, sluggish, and very weak border war. We did not even feel it. Which bacteria are storming our body’s mucous membranes, special importance has not. From the immune system, fights are “frontier guards”, the main force in the fight did not come, so there are no symptoms such as fever, runny nose, cough, and so on.
When we super cool, ie “with a cold”, the situation changes dramatically. Under the influence of low temperature, our body tends to increase heating, and at the same time, reduce the heat consumption. To increase the heating, it “throws wood into the furnace” – speeds up the metabolism, so we feel hungry when frozen. And in order to reduce the heat, our body makes – narrows blood vessels of the skin (which is where does the “goosebumps”), and, at the same time, constricts blood vessels of the mucous membranes. From this mucous receives less blood, and hence less those cells which we call immunity. Our border troops are weakened. It’s like at customs, almost gave up the slack, and the flow of immigrants poured into the country. Arrived call their relatives, have children, and, behold, the indigenous population is already in the minority. Only then did the emigrants – a bacteria.
What happens to the unprotected body?
If a person does not train your body, it teaches him not too cold hardening by the reaction to the cold he did not have adequate. For example, when the average villager wet feet, while the other parts of his body are still warm, he is not that hard to curse and all. But when the same thing happens with the average city dweller, his effeminate body begins to react immediately as if he had been placed in the freezer. He immediately shows signs of a cold. Vasospasm becomes stronger and prolonged, respectively, even a little cold causes fainting protective response in the mucous of the respiratory tract.
Here then begins a sore throat, or, in scientific language, tonsillitis, i.e. a cold treatment which will be long and difficult. Bacteria break emigrants on mucous begin to multiply rapidly and engage in various filthy things. Roughly speaking, they begin to eat our body and do not like it, and come in a regular army already. White blood cells multiply in the lymph nodes become more aggressive and rush into battle. They are true patriots when they cannot kill the enemy, try to at least fill up his body – the so-formed pus on the tonsils. The body declares general mobilization – to white blood cells and other “soldiers” was easier to multiply, the temperature rises. And to throw new crowd “invaders” from the body, begins a runny nose and cough, washing away bacteria and throws them at a speed of about 60 km / h.
And the reason is quite small – the same wet feet, or just a little cold at the bus stop. Smoking, which always enhances any vascular spasms, only helps to capture the process of our body by various bacteria. It is corruption at the customs.
