How a way of life affects immunity in a modern environment: 100,000 words

I. Introduction: Immunity – body shield in the era of change

The modern environment, characterized by rapid technological progress, globalization and changing way of life, has a huge impact on human health, in particular, on the functioning of the immune system. Immunity, a complex and multi -level protection system, protects the body from pathogenic microorganisms, viruses, bacteria, fungi, parasites and own mutated cells. It plays a key role in maintaining homeostasis and preventing the development of various diseases, from ordinary colds to autoimmune disorders and cancer.

Understanding how a lifestyle affects immunity in a modern environment is crucial for maintaining health and well -being. Negative factors, such as chronic stress, environmental pollution, unhealthy nutrition and lack of physical activity, weaken the immune system, making the body more susceptible to diseases. On the other hand, a conscious and healthy lifestyle, which includes proper nutrition, sufficient sleep, regular physical exercises and effective stress control, can significantly strengthen the immune system and increase the body’s resistance to various diseases.

II. Key components of the immune system: the basis of body protection

To understand the influence of lifestyle on immunity, it is necessary to familiarize yourself with the main components of this complex system. The immune system consists of two main branches: congenital and acquired immunity.

A. Inborn immunity: the first line of defense

Congenital immunity is the first line of protection of the body, acting immediately after the penetration of the pathogen. It is characterized by a non -specific reaction, that is, it attacks any alien agent, not distinguishing its species or structure. The components of congenital immunity include:

  1. Physical barriers:

    • Leather: An impenetrable barrier that prevents the penetration of microorganisms.
    • Mucous membranes: Lay the respiratory tract, the gastrointestinal tract and the genitourinary system, secreting mucus that captures pathogens.
    • Eyelashes: Small hairs lining the respiratory tract, pushing mucus and captured pathogens outward.
    • Acidity of the stomach: Desters many microorganisms that fall into the stomach with food.

  2. Cells of congenital immunity:

    • Phagocytes (macrophages, neutrophils, dendritic cells): The pathogens are absorbed and destroyed by means of phagocytosis. Macrophages also play a role in activating acquired immunity.
    • Natural killers (NK cells): Destroy infected cells and cancer cells, without requiring preliminary sensitization.
    • Oblast cells: Histamine and other inflammation mediators release in response to allergens or infections.
    • Eosinophils and basophils: They fight parasitic infections and participate in allergic reactions.

  3. Soluble factors of congenital immunity:

    • Complement: The protein system, which enhances phagocytosis, causes inflammation and directly destroys pathogens.
    • Interferon: Proteins released by infected cells that protect neighboring cells from viral infection.
    • Cytokines: Molecules signaling between the cells of the immune system coordinating the immune response.

B. Acquired immunity: specific and long -term protection

Acquired immunity, also known as adaptive immunity, develops over time after the influence of pathogens. It is characterized by a specific reaction, that is, it is aimed at a particular pathogen and forms an immunological memory that provides long -term protection. The acquired immunity is divided into two main branches: cellular and humoral immunity.

  1. Cellular immunity:

    • T-lymphocytes: Key cells of cellular immunity that recognize antigens (fragments of pathogens) represented by the cells of the body. There are two main types of T-lymphocytes:
      • T-highpers (CD4+ cells): Coordinate the immune response, activating other immune cells, such as B lymphocytes and cytotoxic T-lymphocytes.
      • Cytotoxic T-lymphocytes (CD8+ cells): Destroy infected cells and cancer cells, recognizing antigens presented on their surface.

  2. Humoral immunity:

    • B-lymphocytes: They produce antibodies (immunoglobulins), which are specifically bind to antigens, neutralizing them or marking them to destroy other immune cells. There are various antibodies (IgG, IGM, IGA, IGE, IGD), each of which performs certain functions.
    • Plasmatic cells: Mature B lymphocytes that actively produce and secrete antibodies.
    • Memory cells: Long-living B-lymphocytes and T-lymphocytes that remain in the body after the primary infection and provide a quick and effective immune response with a repeated effect of the same pathogen.

C. Interaction of congenital and acquired immunity:

Congenital and acquired immunity work together, providing comprehensive protection of the body. Congenital immunity is the first to react to pathogens, and then activates the acquired immunity, which provides more specific and long -term protection. Dandrit cells, for example, are key cells connecting congenital and acquired immunity. They absorb pathogens and represent them antigens to T-lymphocytes, activating cellular immunity.

III. The effect of nutrition on immunity: food as a medicine or poison

Food plays a key role in maintaining healthy immunity. The lack of nutrients weakens the immune system, making the body more susceptible to infections. On the other hand, proper nutrition, rich in vitamins, minerals, antioxidants and other beneficial substances, can significantly strengthen the immune system.

A. Lack of nutrients and immune dysfunction:

  1. Protein deficiency: Protein is a building material for the cells of the immune system, including lymphocytes and antibodies. Protein deficiency reduces the amount and function of these cells, weakening the immune response.

  2. Lack of vitamins:

    • Vitamin A: It is important for maintaining the integrity of the mucous membranes that serve as a barrier against infections. Vitamin A deficiency increases the risk of respiratory infections and diarrhea.
    • Vitamin C: An antioxidant that protects the cells from damage by free radicals. It also stimulates the production and function of leukocytes.
    • Vitamin D: Regulates the function of immune cells, such as T-lymphocytes and macrophages. Vitamin D deficiency is associated with an increased risk of autoimmune diseases and infections.
    • Vitamin E: An antioxidant that protects the cells from damage by free radicals. Enhances the function of T-lymphocytes.
    • B vitamins B: Important for energy exchange and maintenance of the health of the nervous system. B vitamins deficiency can weaken the immune response.

  3. Lack of minerals:

    • Zinc: It is important for the development and functioning of immune cells. Zinc deficiency increases the risk of infections.
    • Selenium: An antioxidant that protects the cells from damage by free radicals. It is important for the functioning of the thyroid gland, which also affects the immune system.
    • Iron: It is necessary for the transfer of oxygen and the functioning of immune cells. Iron deficiency weakens the immune response.
    • Copper: Important for the functioning of enzymes involved in the immune response.
