Bad for immunity: myths and reality. Immersion in the world of immunomodulators and their impact on health.

Section 1: What is immunity and why is it important?

Immunity is a complex body of protecting the body aimed at recognizing and destroying foreign agents, such as bacteria, viruses, fungi, parasites and other potentially dangerous substances. This is not just a single organ or system, but a combination of cells, tissues, organs and mechanisms working in a close relationship.

  • Inborn immunity: The first line of defense of the body, acting immediately against any threats. It includes physical barriers (leather, mucous membranes), chemical barriers (saliva, tears, gastric juice), as well as fagocytes (neutrophils, macrophages) that absorb and destroy foreign agents. Congenital immunity does not have specificity, that is, reacts equally to all threats.
  • Acquired immunity (adaptive immunity): It develops throughout life after contact with antigens (foreign substances). It has specificity, that is, it remembers the antigen and reacts to it more effectively with re -infection. The acquired immunity is divided into:
    • Cellular immunity: It is provided by T-lymphocytes (T-killer, T-Helpers). T-killers destroy infected cells, and T-Helpers help other cells of the immune system.
    • Humoral immunity: It is ensured by B-lymphocytes that produce antibodies (immunoglobulins). Antibodies bind to antigens and neutralize them or facilitate their absorption by phagocytes.

The role of immunity in maintaining health:

A strong immune system is vital for protection against diseases, maintaining overall health and longevity. She plays a key role in:

  • Protection against infections: Prevents or reduces the severity of infectious diseases.
  • Removal of damaged cells: It destroys old, damaged or mutated cells, preventing the development of cancer.
  • Regulation of inflammation: Supports the balance between inflammation and its suppression, preventing chronic diseases.
  • Wound healing: Participates in the healing process of wounds and tissue restoration.

Factors affecting immunity:

Many factors can affect the state of the immune system, both positively and negatively. These include:

  • Age: Immunity weakens with age (immunostation).
  • Nutrition: The lack of nutrients, such as vitamins, minerals and proteins, can weaken the immune system.
  • Dream: The lack of sleep suppresses the immune function.
  • Stress: Chronic stress weakens the immune system.
  • Physical activity: Moderate physical activity strengthens the immunity, while excessive physical activity can weaken it.
  • Chronic diseases: Some chronic diseases (diabetes, cardiovascular diseases, autoimmune diseases) can weaken the immune system.
  • Medicines: Some drugs (immunosuppressants, corticosteroids) can suppress the immune system.
  • Smoking and alcohol: Smoking and alcohol abuse weaken the immunity.
  • Environmental factors: The impact of environmental pollution can weaken the immune system.
  • Genetics: A genetic predisposition also plays a role in the strength of the immune system.
