All people want to be he althy. After all, not only the physical, but also the psychological state of a person depends on this: the desire to live, create and just enjoy every day. But why does immunity and the immune system sometimes fail?
Definition of concept
In simple terms, everyone knows what immunity is. This is what is responsible for the he alth of each person. But if you dig deeper and delve into the essence of things, then the work of the immune system is a huge undertaking, a whole chain of mechanisms of the human body, which is responsible for its safety, protects it from the effects of any viruses and bacteria that are dangerous to he alth. What the immune system and the immune system actually do: recognize cancer cells, remove toxins, neutralize free radicals, kill various viruses and microbes that enter the body. The very essence of human immunity is to maintain he alth in any way.
Structure
Immunity and the immune system are born with a person and die withhim. But it should be noted that immune protection can be of several types: both innate and acquired. If everything is clear with the first, because it has existed and developed together with man since ancient times, then the second is third-party he alth assistants. Congenital defense is a cough, runny nose, vomiting and diarrhea, as well as other manifestations of the body, with the help of which it tries to get rid of "unwanted guests" - various viruses and infections that threaten human he alth. Acquired immune protection is various vaccinations, as well as the resistance of the body, which arose as a result of previous diseases: rubella, chickenpox and the like.
Diseases
But a person's immunity and immune system may not always be in perfect condition. And such important elements for he alth sometimes also give various failures. Such diseases are dangerous because when the immune system is damaged, the whole body suffers from this, because it simply turns out to be unprotected against numerous dangers. They are divided into two large groups: autoimmune diseases, when the body takes its own tissues as enemy and attacks itself (arthritis, sclerosis, diabetes, etc.); immunodeficiency, when the immune system and the immune system do not work at full strength or simply refuse to perform their duties. Most often, diseases such as hepatitis C, AIDS, and tuberculosis are associated with this.
Help
It should be noted that the immune system and the immune system are able to receive help from outside. Simply put, you can constantly improve your he alth in various ways. The simplest and least expensive of them: proper, balanced nutrition, he althy sleep and sufficient rest to restore strength, an active lifestyle and moderate physical activity. The consumption of vitamins, exposure to fresh air have a good effect on immunity. Hardening also helps a lot - it makes a person stronger and more resilient. It is necessary to teach children such methods of maintaining their body from early childhood, explaining what immunity and the immune system are. The abstract in this case is a great helper. Also, various articles, notes of doctors can be used as supporting material.
