How to improve immunity with dietary supplements: full management

Section 1: Understanding the immune system and its role

The immune system is a complex network of cells, tissues and organs working together to protect the body from pathogens, such as bacteria, viruses, fungi and parasites. It is vital for survival, since it allows us to withstand constant attacks of pathogens present in the environment. Non -varnishes in the immune system can lead to various health problems, from frequent infections to autoimmune diseases.

  • Inborn immunity: The first line of the body’s defense. It provides an immediate, but non -specific response to invading pathogens. Key components include:
    • Physical barriers: Leather, mucous membranes, hair and eyelashes.
    • Cells: Macrophages, neutrophils, natural killers (NK cells) and fat cells.
    • Inflammation: Localized answer that attracts immune cells to the place of infection.
    • Interferon: Proteins that prevent the reproduction of viruses.
  • Adaptive immunity: It develops over time and provides specific and long -term immunity. He learns to recognize and memorize specific pathogens in order to fight them more effectively in the future. Key components include:
    • B cells: Produce antibodies that neutralize pathogens or mark them to destroy other immune cells.
    • T-cells:
      • T-highpers (CD4+ cells): Help b-cells and other immune cells to function.
      • Cytotoxic T cells (CD8+ cells): Destroy infected cells.
    • Immunological memory: The ability of the immune system to remember the pathogens with which it has encountered earlier, and more quickly and more efficiently respond to them in the future. This is the basis of vaccination.

Factors affecting immunity:

Many factors can affect the function of the immune system, both in the positive and in the negative direction.

  • Age: The immune system weakens with age (immunostation), which makes the elderly more susceptible to infections.
  • Diet: Unstable nutrition, deficiency of vitamins and minerals, as well as excessive use of processed products can weaken the immune system.
  • Stress: Chronic stress releases cortisol, which suppresses the function of the immune system.
  • Dream: The lack of sleep violates the production of cytokines, proteins that regulate immune answers.
  • Physical activity: Moderate physical exercises strengthen the immune system, while excessive training can temporarily suppress it.
  • Bad habits: Smoking and excessive alcohol use weaken the immune system.
  • Medical conditions: Some diseases, such as HIV/AIDS, autoimmune diseases and cancer, can seriously disrupt the function of the immune system.
  • Medicines: Some drugs, such as immunosuppressants, can suppress the immune system.
  • Genetics: Genetic factors also play a role in determining the strength and effectiveness of the immune system.

Section 2: Dans to support immunity: Review

Biologically active additives (dietary supplements) can be useful in supporting the immune system, especially when there is a deficiency of certain nutrients or when the immune system is stressed. It is important to understand that dietary supplements are not a replacement for a healthy lifestyle, which includes a balanced diet, regular physical exercises, sufficient sleep and stress management. Before taking any dietary supplements, it is recommended to consult a doctor to make sure that they are safe and suitable for your individual needs.

  • Vitamin C (ascorbic acid):
    • The mechanism of action: A powerful antioxidant protects cells from damage caused by free radicals. Supports the function of immune cells, such as phagocytes and T cells. Participates in the synthesis of collagen, important for the health of the skin and mucous membranes, which are physical barriers for infections.

The lack of sleep reduces the production of cytokines, which can lead to a decrease in immunity. Strive by 7-8 hours of quality sleep every night.
  • Stress: Chronic stress suppresses the function of the immune system. Stress releases cortisol, stress hormone, which can suppress the function of immune cells. Find the ways of managing stress, such as meditation, yoga, walking in nature, communication with friends and relatives, or classes of your favorite hobby.
  • Physical activity: Moderate physical exercises strengthen the immune system. Physical activity improves blood circulation, which allows immune cells to move more efficiently around the body and fight infections. It is recommended to engage in physical exercises of medium intensity of at least 150 minutes a week. Examples of moderate physical exercises include walking, swimming, cycling and dancing.
  • Hygiene: Compliance with hygiene rules, such as frequent hand washing, can help prevent the spread of infections. Wash your hands with soap and water for at least 20 seconds, especially after visiting public places, before eating and after coughing or sneezing.
  • Refusal of bad habits: Smoking and excessive alcohol use weaken the immune system. Smoking damages the lungs and reduces the body’s ability to fight respiratory infections. Alcohol suppresses the function of immune cells.
  • Vaccination: Vaccination is an effective way to protect against infectious diseases. Vaccines stimulate the immune system to the production of antibodies, which protect the body from specific pathogens. Discuss with the doctor which vaccines you need.
  • Maintaining a healthy weight: Obesity is associated with chronic inflammation and a decrease in the function of the immune system. Maintaining healthy weight with a balanced diet and regular physical exercises can improve immunity.
  • Regular medical examinations: Regular medical examinations allow you to identify and treat diseases in the early stages, which can prevent the weakening of the immune system. Discuss with the doctor your risks and necessary preventive measures.
