Why others don't get sick? Because they care about themselves – This is the simplest answer. In the war with the disease outside the already mentioned guards (cilia) A strong immune response to a germ attack is important. The defense capabilities of the nose and entire respiratory tract depend primarily on the rate of mobilization and the number of so -called. immune cells, efficient secretion of immunoglobulins, etc.. A strong immune response consists of the efficient operation of all immune mechanisms. Attention! You can train them. How? By hardening the body in recent years. You need to get used to the capillaries of the nasal mucosa and upper respiratory tract to sudden temperature changes. Of course, nobody tells you to run naked in snow and frost. The sauna will certainly be invaluable. Not, not, Hardening can be a pleasure.
Cold viruses first destroy the nasal and throat mucosa cells. The effect of this activity is acute inflammation of the mucosa (His symptoms are: train, cough, sore throat, itching of the throat), and consequently abundant release of irritants. The body begins to fight with itself, because, as a result of the virus invasion, some epithelial cells are dead and peeling. Craze cells that remove mucus with viruses and impurities falling into the nose and cup cells producing defensive substances are also destroyed. After their damage, the viruses already have an open path to the whole body.
When it comes to preventing colds and flu, You must remember, that even being completely healthy, You are most likely infected with many viruses. Some even always "live" in your body. As long as they are kept in check by the immune system, They are unable to hurt you. Lots of viruses "live in" your respiratory and digestive system. The latter are even necessary, because they help you digest. Even these helpful viruses will become absolute pathogens, If you allow even minimal weakening of immunity. Most often, immune mechanisms are damaged by fatigue. So especially in autumn, take care of enough sleep, outdoor movement and avoid too long and exhausting trampling at work. If you already have to sit in it, Take care of it at least, not to work during weekends. However, instead of sitting at home, Go somewhere outside the city and be sure to turn off your mobile phone.
