In its fight against pathogens and viruses, the body strives to maintain its health and stay away from anything that harms it. However, sometimes viruses, etc., reach the target and the infection causes coughing, runny nose or even more serious.
If this happens frequently, it indicates the weakness of the immune system. But, what is the immune system?
To answer this question, Professor Ulrich Fulch, a specialist in internal medicine and gastrointestinal tract, said that it was a very complex system that spread throughout the body and is an interaction between cells, tissues and chemical media.
The action of the immune system begins with the skin, which provides a protective barrier against germs attacks and contains a slightly acidic pH that prevents bacteria and others from entering the body.
Membranes, nasal hair and bronchi prevent the passage of bacteria in the body.
If the bacteria can enter the body through the food, it is the saliva that tries to fight it, and if it fails, the acid from the stomach takes over.

Natural and specialized defense
He pointed out that there is also a so-called "natural defense", namely that the body's cells simply eat anything that looks strange to the body. These macrophages are called "macrophages" or individual cells.
If this natural defense fails to eliminate pathogens, the body activates the specialized defense, called B-cells and T-lymphocytes, mainly belonging to the group of white blood cells.
These cells develop antibodies that particularly affect known pathogens in the body.
He says that the immune system has a similar memory and remembers that he had already been treated with this bacteria.If the body undergoes a new attack of the same pathogen, the specialized immune system recognizes it and eliminates it. quickly.
The person who has scarlet fever will not contract it, unlike the flu, because its composition changes constantly, so that the flu manifests itself more than once in his life.
Causes of immunodeficiency
Infections occur when the immune system weakens. This weakness is due to several reasons, including lack of sleep and constant psychological stress, as well as chronic diseases such as diabetes and AIDS.
Ursula Zellerberg, a German pharmaceutical company, pointed out that drugs could be at the root of a weak immune system and that antibiotics could only be administered under the supervision of a doctor. The digestion process is smooth.
The immune system can be strengthened with simple weapons for a healthy and balanced diet, as well as regular exercise and outdoor activities, taking into account regular hand washing, Zellerberg said.
A good weapon is also to get enough sleep at night, while psychological stress can be fought through relaxation techniques such as yoga and meditation.
