Improve Immunity

How does our IMMUNE System Work?

Immunity is the body’s defense mechanism that combats dangerous intruding substances ( antigens) which include infective microorganisms (pathogens) and irritations. It is comprised of different types of White Blood Cells (WBCs) and their interconnected system that can be compared to the structure and operation of an Army.

WBCs may contain significant granules (granulocytes or WBCs with granular structure) or otherwise (agranulocytes or Agranular WBCs). Granulocytes are composed of neutrophils, eosinophils along with Basophils in blood, as well as mast cells in tissues. They are able to produce substances within the Granules (like histamine, kininsperoxidase enzymes, etc.).) which fight any foreign substance (antigen) that has invaded the body. monocytes within the blood (transform into macrophages within tissue) are WBCs that have small, less prominent granules and thus are classified as Agranular Type. These cells, especially macrophages and neutrophils, are part of our natural immunity and are similar to soldiers in the army. They detect the molecular signatures of pathogens (PAMPs) on infectious organisms by using their surface ‘antennae’, also known as toll-like receptors (TLRs).

If the infection is serious, long-lasting, and uncontrollable by our soldiers in the army, the ‘officers’ of the army, which are lymphocytes (WBCs with no granules) are referred to as in. The lymphocytes (two kinds – B and T lymphocytes) are the source of our adaptive immunity. The T lymphocytes including helping T cells as well as the killer T cells are more sophisticated in their detection, strategy, and fighting strategies.

The helper cells (also known as CD4 cells) activate B lymphocytes in order to make specific antibodies (also known as immunoglobulins, Ig) that act on the outside of cells, by forming bonds to and eliminating that specific Antigen (humoral immunity). The different types of antibodies are IgM (formed during infections quicker but with a shorter duration), IgG (formed during later infections but lasts longer), IgE (formed in the case of allergies and parasite infections), and IgA (for local immune response at entry points). Therefore, in laboratory tests for any disease, the tests for antigens are positive right away, but it takes several days before testing positive for the antibodies.

Killer T cells (also known as T-cells that are cytotoxic or CD8) accomplish their tasks through direct destruction of the cell through the presence of antigens in the cell ( cell-mediated immunity). Immunity mediated by antibodies can be evident in all types of infections but, cell-mediated immunity is essential to effectively fight pathogens inside cell walls (intracellular). This includes fungi, viruses as well as certain organisms (like the one responsible for TB) along with parasites.

Thus, the adaptive immunity by lymphocytes is more specific in its approach and also has memory because of the IgG antibodies and a few T lymphocytes (helper and killer) that become long-term memories T cells. This is a way to have a more rapid and effective reaction to the antigen that is attacked repeatedly, and the destruction occurs before we realize it or display symptoms! This is referred to as “being immune” to an illness.

The need for regulatory checks is to ensure that no system is out of balance. This is accomplished in the immune system of our body by regulating T cells (also known as suppressor T cells). The Immune system also has messenger proteins known as Cytokines (interleukins as well as interferons) that circulate between cells to relay information and messenger cells, such as antigen-presenting cells (APCs) that aid in the activation of antigen-induced helper T cells.

The blood’s fluid (called plasma) is a source of proteins known as”the” immune system (C1-9) which are also involved in the immune system by helping granulocytes as well as antibodies in eliminating the irritant or infectious agent


Immune deficiencies are the result of a disorder in any component of the Immune system. They could appear or could be (genetic or exist from birth) such as the condition known as Severe Combined Immune Deficiency (SCID – a disorder of lymphocytes B and T), Chediak Higashi disease (defect of neutrophils and granulocytes), and other diseases of this kind.

In the majority of cases, immune deficiency tends to be more often secondary and can be seen in diseases such as HIV (a reduction in T helper CD4 lymphocytes) and in patients using bone marrow suppressing drugs (chemotherapy radiation) or long-term high dose corticosteroid drugs. It is also observed in patients with severe malnutrition seniors over 70 and patients who suffer from significant heart, lung, or kidney illness. Patients with these conditions are at risk of infections. Even minor infections can cause them to become extremely ill and can be life-threatening. Patients with these conditions require an extreme level of protection as well as rigorous treatment.

Reduced or sub-optimal immunity may be seen in many people due to inappropriate diet, lifestyle, stress, or during an illness/convalescence. It can cause a person to contract frequent and common infections rapidly and frequently as well as take longer healing time. These people are often diagnosed with cough, cold, and fever, as well as bowel issues as well as weakening of the body, and fatigue. This is easily cured or avoided by living a healthy and balanced lifestyle.

Important Factors to Maintain A healthy immune system

They are the five Big Five: Diet Lifestyle and Sleep, Physical Activity, and Hygiene Protection


A healthy diet with high levels of proteins as well as vitamins (A, B, C, D, and E) as well as minerals (zinc selenium, zinc-iron) together with a few spices and herbs are essential to maintain optimal immunity. A sufficient amount of drinking 10-12 glasses per day (at minimum 2.5 milliliters of preferably warm water) to maintain healthy drinking habits is essential.


Globally, modern lifestyles are associated with a great deal of stress. Stress is where the body is conditioned to deal with the stressors (physically as well as emotionally) than it could. Stress, anxiety, and tension result in an increase in the consumption of resources and nutrients and weaken our immune system. Stress results in releases of corticosteroids within the body, which can also reduce our immune system. A balanced family life, a positive attitude as well as a balance between work and life, as well as fun activities can reduce tension and stress. The likelihood of contracting infections or becoming in a state of illness is an indication of stress and weakening immunity. This is why it is important to think about being aware of control of stress. Smoking, chewing tobacco, or excessive drinking of alcohol can affect immunity.


Sleep can have a variety of impacts on the system of immunity, including the better function of lymphocytes APCs, cytokines, and the production of antibodies. A decrease in the time or the quality could decrease the immune system. It is therefore essential to establish a routine to get 8 hours of uninterrupted sleeping at night most days. Sleep deprivation and stress are often linked and be a vicious circle that can cause each to increase the other.

Physical Training

Regular, appropriate exercise that makes you feel fresh and energetic is linked with boosting your immunity. It is crucial to ensure that your exercise does not be strenuous, more intense and more strenuous than the one you are accustomed to, causing injuries or pain to the body, or be done in unwelcome surroundings, since in these circumstances it creates stress, which can negatively impact the body’s immune system.

If you are beginning a new fitness routine begin by increasing the intensity and intensity gradually, perform proper warm-ups and cooldowns and stop when the body shows stress or fatigue. The most appropriate physical activities include walking, swimming, and jogging or indoor activities such as Yoga and stretching exercises and walking on the treadmill cycling, and aerobics. Include these exercises for at least a half-hour every day for 5 days per week, along with breathing techniques is suggested and can boost your immune system. Games and sports in the outdoors can provide physical exercise, mental relaxation, and social connection.

Hygiene and Protection

Hygiene and cleanliness in the simplest everyday habits such as proper cleaning and bathing of body areas, wearing clean clothes hand washing before meals and when you come from outside, regularly brushing teeth and covering mouth and nose when coughing or sneezing not spitting out or throwing waste in public, and maintaining cleanliness in the environment, help in keeping infections at bay and improving the community’s health.

It is crucial to ensure that children as well as those in danger, such as those who have health issues are vaccinated in accordance with the recommended immunization schedule in order to protect them from more serious and dangerous illnesses. Vaccines utilize dead or weak live organisms (whole or part) that expose patients to the specific pathogen and activate the adaptive immune response that produces memories and antibody T cells. Thus, vaccinations provide long-term protection against that specific infection, without actually suffering from it. If a large portion of an entire group is vaccination-free (or exposed to the particular infection) and the spreading of the infection can be reduced even to individuals who aren’t vaccinated (or even exposed). This is known as herd immunity.

Certain methods like the administration of antibiotics to treat commonly-occurring viral illnesses, a lack of frequent exposure to the natural world, sunlight or fresh air as well as living in houses that are not ventilated can have a suppressive effect on the body’s immune system. It’s like reducing the ability to be alert and training the military!

If there is an outbreak or pandemic It is advised to adhere to the rules of health authorities pertaining to restrictions on movement, social isolation, and hygienic precautions. Although this doesn’t directly boost the immunity of people, it does allow the protection of people and slows down the spreading of the disease.

There are numerous products that are available on the market, including herbal and pharmacological mixtures, and claims that they are ‘ immune boosters or boosting the immune system. A majority of them do not provide solid or reliable scientific evidence that shows benefits that go beyond the benefits of a balanced, nutritious lifestyle and diet, whether in the immediate or long-term impacts. Supplements based on certain nutrients from your diet may not be effective in the absence of a healthy, holistic lifestyle and may in fact create a false impression of self-confidence. So, it is recommended to supplement these with the supervision of a physician or as directed by a medical professional for situations of restriction on physical or dietary activity or malnutrition and nutritional deficiencies found in laboratory tests, convalescence, or particular risk factors or medical circumstances.


Autoimmunity (autoimmune disorder or disease) is an illness in which the immune system perceives the tissue of the body as being foreign because itself against foreign recognition mistakes. The immune system is activated and the body’s antibodies (called autoantibodies) are made that attack and target these tissues of the body. These cells and tissues result in damage and illness. Autoimmune disorders include thyroid conditions, rheumatoid arthritis, type 1 diabetes, psoriasis, and lupus.
