Effective additives to increase immunity in the cold season
Chapter 1: Understanding the immune system and the seasonality of diseases
-
1 The fundamental principles of the immune system:
- Inborn immunity: The first protection line, including physical barriers (skin, mucous membranes), chemical barriers (acidity of the stomach, lysisocym in saliva and tears) and cell components (macrophages, neutrophils, NK cells). Macrophages, for example, are phagocytes that absorb and digesting pathogens. Neutrophils are the most numerous leukocytes, also participating in phagocytosis and the release of cytotoxic substances. NK cells (natural killers) destroy infected cells and tumor cells, without requiring preliminary sensitization.
- Acquired immunity: It develops over time after exposure to antigens (foreign substances). Includes humoral immunity (B cells that produce antibodies) and cell immunity (T cells that directly attack infected cells or regulating the immune response). B cells recognize antigens and differentiate into plasma cells that secrete antibodies. Antibodies bind to antigens, neutralize them or facilitate their destruction by other immune cells. T-highpers coordinate the immune response, activating the B cells and cytotoxic T cells. Cytotoxic T cells (CD8+ T cells) destroy cells infected with viruses or other intracellular pathogens. T-regulatory cells suppress the immune response, preventing autoimmune reactions.
- The role of cytokines: Signal molecules used by immune cells to communicate with each other and coordination of the immune response. Examples include interleukins (IL), interferons (IFN) and tumor necrosis factor (TNF). Interleukins regulate the growth and differentiation of immune cells. Interferons have antiviral activity and activate immune cells. The factor of tumor necrosis is involved in inflammation and apoptosis (programmed death of cells).
- Immunological memory: The ability of the immune system to quickly and effectively respond to antigens that it had previously encountered. It is based on the formation of memory cells (B cells of memory and T-cells of memory), which remain in the body after the primary infection and are quickly activated when the same antigen is repeated.
-
2 Factors weakening immunity:
- Lack of sleep: Violates the production of cytokines and reduces the activity of NK cells. The lack of sleep (less than 7-8 hours a day) can lead to increased susceptibility to infections.
- Chronic stress: Increases the level of cortisol, which inhibits the function of immune cells. Chronic stress negatively affects the function of T cells and reduces the effectiveness of vaccination.
- Inal meals: The lack of necessary nutrients, such as vitamins, minerals and protein, weakens immune cells. The deficiency of zinc, selenium, iron, vitamins A, C, D and E can seriously disrupt the immune function.
- Dehydration: Reduces the volume of blood and lymph, making it difficult to transport immune cells. Dehydration can also lead to a decrease in mucus production, which is an important barrier against pathogens.
- Lack of physical activity: Reduces the circulation of immune cells. Moderate physical exercises (for example, walking, jogging, swimming) can improve the function of the immune system. However, excessive physical activity can temporarily suppress the immune function.
- Smoking and drinking alcohol: Damage immune cells and mucous membranes. Smoking damages the cilia in the respiratory tract, making it difficult to remove pathogens. Alcohol disrupts the function of neutrophils and macrophages.
- Some drugs: For example, corticosteroids and immunosuppressants suppress the immune system. These drugs are often used to treat autoimmune diseases and organs transplantation, but they increase the risk of infections.
- Environmental pollution: The influence of toxins and pollutants can weaken the immune system. Air pollution, for example, can damage the lungs and increase susceptibility to respiratory infections.
-
3 Seasonality of colds:
- Winter period: Favorable conditions for the spread of viruses due to low humidity and more frequent stay of people in closed rooms. The low humidity allows the viral particles to stay in the air longer and is easier to spread.
- Vitamin D: A decrease in the synthesis of vitamin D in the skin due to the smaller effects of sunlight in the winter months. Vitamin D plays an important role in the immune function, and its deficiency can increase susceptibility to infections.
- The condition of the mucous membranes: Cold and dry air can cause dryness and damage to the mucous membranes of the respiratory tract, making them more susceptible to infections.

- Excessive physical activity: Excessive physical activity can temporarily suppress the immune function.
- Recommendations: Try to engage in moderate physical activity of at least 30 minutes a day of most days of the week.
-
8 Hygiene:
- Regular hand washing: Frequent washing with soap and water is one of the most effective ways to prevent the spread of infections.
- Avoiding the touch of the face: Avoid touching the face, especially the eye, nose and mouth, as this allows pathogens to penetrate the body.
- Covering the mouth and nose with coughing and sneezing: Cover your mouth and nose with an elbow or a napkin when coughing and sneezing to prevent the spread of drops containing pathogens.
-
9 Sufficient water consumption:
- The importance of hydration: Dehydration can reduce the volume of blood and lymph, making it difficult to transport immune cells. Dehydration can also lead to a decrease in mucus production, which is an important barrier against pathogens.
- Recommendations: Try to drink at least 8 glasses of water per day.
