Causes of low immunity and ways to strengthen it

In its fight against pathogens and viruses, the body does everything in its power to stay healthy and stay away from anything that harms it. However, viruses or others can reach the target and cause an infection of cough, runny nose or worse. 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 of Germany has stated that the immune system is a very complex system that spreads throughout the body and is an interaction between cells, tissues and chemical environments of all kinds.
Immunity starts with the skin

The specialist in internal medicine and the digestive system considers that the work of the immune system starts from the skin, which is a barrier against germs attacks; when the skin contains an acid pH, it somewhat prevents the infiltration of bacteria and other body elements. Membranes, nasal hair and bronchi prevent the passage of bacteria in the body.

If bacteria can enter the body through food, it is the saliva that tries to fight it. In case of failure, gastric acid takes over.

Natural and specialized defense

There is also what is called the "natural defense", which consists of body cells that devour everything that seems strange to the body. One of these macrophages is called "placenta" or only cells.

If this natural defense fails to eliminate the pathogens, the body then activates the specialized defense, called B-cells and T-cells, which belong to the white blood cell group. These cells develop antibodies that particularly affect known pathogens in the body.

The immune system has a similar memory and remembers that it had already been treated with these germs: if the body has to face a new attack by the same cause of the disease, the specialized immune system recognizes it and l & # 39; 39, eliminates quickly.

The person who has scarlet fever will no longer contract the disease, unlike the flu, because its composition continuously changes in composition, so you usually have the flu more than once in your 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, explained that drugs could be the cause of a weak immune system and could only be administered under the supervision of a doctor. Digestion is smooth.

Zellerberg said that the immune system can be strengthened with simple weapons of healthy and balanced diet, in addition to the practice of sports and outdoor activities, taking into account the fact of washing hands regularly.

A good weapon is also adequate sleep at night, while psychological stress can be fought through calioga relaxation techniques and meditation.
