Bad for immunity: protection of the body in the cold season

Part 1: Understanding the immune system and its role

The immune system is a complex network of cells, tissues and organs that work together to protect the body from harmful invaders, such as bacteria, viruses, fungi and parasites. An effective immune system is able to recognize and destroy these threats, preventing the development of diseases and contributing to general health. Understanding the main components and mechanisms of the immune system is critical of a conscious approach to its support, especially during periods of increased incidence.

1.1 components of the immune system:

  • Leather and mucous membranes: The first line of defense, a physical barrier that prevents the penetration of pathogens. The skin emits antimicrobials, and the mucous membranes lining the respiratory tract and the digestive tract contain immune cells and substances that neutralize viruses and bacteria.

  • Leukocytes (white blood cells): Key players in the immune response. There are several types of leukocytes, each of which performs its own specific function:

    • Neutrophils: Fagocytes that absorb and destroy bacteria and fungi. They are the first to arrive at the infection.
    • Lymphocytes: They are divided into B cells, T cells and NK cells (natural killers).
      • B cells: They produce antibodies, specific proteins that are associated with pathogens and neutralize them or are noted for the destruction of other immune cells.
      • T-cells: They help B-cells produce antibodies (T-highpers), kill infected cells (cytotoxic T cells) and regulate the immune response (regulatory T cells).
      • NK cells: Infected cells and cancer cells are killed, without requiring preliminary sensitization.
    • Monocytes: They turn into macrophages, phagocytes that absorb and digest pathogens, cell garbage and other foreign substances. They also present antigens of T-cells, launching an adaptive immune response.
    • Eosinophils and basophils: Participate in the fight against parasites and allergic reactions.

  • Lymphoid organs: Places of ripening, storage and activation of immune cells:

    • Bone marrow: The formation of all blood cells, including leukocytes.
    • Timus (thymus iron): The ripening place of T cells.
    • Lymphatic nodes: They filter lymph, contain lymphocytes that are activated when antigens are detected.
    • Spleen: He filters blood, removes old and damaged blood cells, contains lymphocytes.
    • Tonsils and adenoids: Protect the upper respiratory tract from infections.
    • Payerovs of plaques (in the small intestine): They contain lymphocytes that control the bacterial flora of the intestine and respond to pathogens.

1.2 types of immunity:

  • Inborn immunity: The first line of protection, nonspecific. Includes physical barriers (skin, mucous membranes), cells (neutrophils, macrophages, NK cells) and proteins (complement). He reacts quickly, but does not provide long -term protection.

  • Adaptive immunity: Specific immunity developing in response to the effects of antigens. Includes B cells and T cells. It reacts more slowly than congenital immunity, but provides long -term protection (immunological memory).

1.3 Factors affecting the immune system:

Many factors can affect the function of the immune system:

  • Age: The immune system is less effective in infants and elderly people.
  • Nutrition: The lack of nutrients, such as vitamins, minerals and proteins, can weaken the immune system.
  • Stress: Chronic stress can suppress the immune system.
  • Dream: The lack of sleep can weaken the immune system.
  • Physical activity: Moderate physical activity can improve the function of the immune system, but excessive physical activity can suppress it.
  • Smoking and alcohol: Smoking and alcohol abuse can weaken the immune system.
  • Diseases: Some diseases, such as HIV/AIDS, autoimmune diseases and cancer, can weaken the immune system.
  • Medicines: Some drugs, such as corticosteroids and immunosuppressants, can weaken the immune system.
  • Genetics: Genetic factors can also affect the function of the immune system.
  • Environmental factors: Environmental pollution can weaken the immune system.

Part 2: Dietary supplements to support immunity: review and action mechanisms

Biologically active additives (dietary supplements) can play a role in maintaining the immune system, providing the body with the necessary nutrients and other compounds that can improve its function. However, it is important to remember that dietary supplements are not a replacement for a healthy lifestyle, including a balanced diet, sufficient sleep, regular physical exercises and stress management. Consultation with a doctor or a qualified nutritionist before taking any dietary supplements is required, especially if there are any diseases or medication.

2.1 Vitamin C (ascorbic acid):

  • The mechanism of action: Vitamin C is a powerful antioxidant that protects the cells from damage by free radicals. It is also important for the function of immune cells, such as neutrophils and lymphocytes. Vitamin C promotes the production and functioning of leukocytes, enhances phagocytosis (absorption and destruction of pathogens) and stimulates the production of interferon, protein, which prevents the multiplication of viruses. It is also necessary for the synthesis of collagen, an important component of the skin and mucous membranes, which are physical barriers that prevent the penetration of pathogens.

  • Dosage: The recommended daily dose of vitamin C varies depending on age, floor and health. For adults, 75-90 mg per day is usually recommended. During periods of increased incidence, dosage can be increased to 200-1000 mg per day, but it is important not to exceed the upper permissible level of consumption (2000 mg per day) in order to avoid side effects, such as stomach disorder.

  • Forms: Vitamin C is available in various forms, including tablets, capsules, powders and chewing sweets. Liposomal vitamin C can have better bioavailability than ordinary vitamin C.

2.2 Vitamin D (cholecalciferol):

  • The mechanism of action: Vitamin D plays an important role in the regulation of the immune system. It binds to vitamin D (VDR) receptors, which are present on immune cells, such as macrophages, dendritic cells and lymphocytes. Vitamin D promotes the activation of macrophages, enhances the products of antimicrobial peptides (defensins and katelicidin), which destroy bacteria, viruses and fungi, and regulates inflammatory processes. Vitamin D deficiency is associated with an increased risk of infectious diseases, autoimmune diseases and cancer.

  • Dosage: The recommended daily dose of vitamin D is 600-800 IU (international units) for adults. During periods of increased incidence and with vitamin D deficiency, the dosage can be increased to 2000-4000 IU per day under the supervision of a doctor. It is important to regularly check the level of vitamin D in the blood to avoid an overdose.

  • Forms: Vitamin D is available in the form of vitamin D2 (ergocalciferol) and vitamin D3 (cholegalciferol). Vitamin D3 is usually more effective than vitamin D2.

2.3 zinc:

  • The mechanism of action: Zinc is necessary for the normal functioning of immune cells, including neutrophils, NK cells and lymphocytes. It is involved in the regulation of cellular immunity, antibodies and inflammatory processes. Zinc promotes the ripening of T-lymphocytes in the thymus, enhances the activity of the NK cells and stimulates the production of interleukin-2, an important cytokine for activating T-cells. Zinc deficiency is associated with an increased risk of infectious diseases, slowed down wound healing and growth disorders.

  • Dosage: The recommended daily dose of zinc is 8-11 mg for adults. During periods of increased incidence, dosage can be increased to 15-30 mg per day, but not more than 40 mg per day, to avoid side effects, such as stomach disorder and a violation of copper assimilation.

  • Forms: Zinc is available in various forms, including zinc gluconate, zinc sulfate, zinc picoline and zinc acetate. Qing Picoline can have better bioavailability than other forms of zinc.

2.4 Selenium:

  • The mechanism of action: Selenium is an important trace element that is involved in the antioxidant protection and regulation of the immune system. It is part of selenoproteins that play the role in protecting cells from damage by free radicals and regulate the immune response. Selenium promotes the activation of NK cells, enhances cytokine products and modulates inflammatory processes. Selenium deficiency is associated with an increased risk of infectious diseases, autoimmune diseases and cancer.

  • Dosage: The recommended daily dose of selenium is 55 mcg for adults. During periods of increased incidence, dosage can be increased to 100-200 mcg per day, but not more than 400 mcg per day to avoid side effects, such as nausea, diarrhea and hair loss.

  • Forms: Selenium is available in various forms, including selenometionine and sodium selenite. Seleenomeininin can have better bioavailability than sodium selenite.

2.5 probiotics:

  • The mechanism of action: Probiotics are living microorganisms, which, when used in sufficient quantities, have a positive effect on the health of the owner. They contribute to maintaining a healthy intestinal microflora, which plays an important role in the immune system. Probiotics compete with pathogenic bacteria for nutrients and attachments in the intestines, produce antimicrobials, stimulate the production of immunoglobulin A (IGA), antibodies that protect the mucous membranes from infections, and modulate the immune response. Healthy intestinal microflora helps to train the immune system, improving its ability to recognize and destroy pathogens.

  • Dosage: The dosage of probiotics varies depending on the strain and the product. It is usually recommended to use probiotics containing several billions of colony -forming units (CFUs) per day.

  • Strains: Some of the most studied and useful strains of probiotics include Lactobacillus Rhamnosus GG, Lactobacillus Acidophilus, Bifidobacterium Lactis and Saccharmyces Boulardii. It is important to choose probiotics containing strains, the effectiveness of which is proved by clinical research.
