What is immunity? Or why do we get sick?

Have you ever thought about why we get sick? Or why some get sick more often and others much less often? And why do almost all children who have entered a new kindergarten or school get sick one after another?

If we ask these questions to a non-medical person, at best we will get some vague answers that it all depends on the person's immunity and how "muddy" his body is. And in principle, he will be right, but to the question "What exactly is immunity?" hardly anyone will give a clear answer.

For many people since childhood immunity is associated with some invisible armor that protects our body from germs and when this armor cracks, we get sick. But medicine has a precise definition of the concept of the body's immune status. So here is the exact definition "A person's immune status is a set of laboratory indicators characterizing the quantitative and functional activity of the cells of the immune system at a given time." In simpler terms, immunity is a kind of combination of different cells in our body that act in a kind of synergy to protect us from various challenges, both external (like infections) and internal (like cancer, for example). And the quantity and quality of their composition determines what our immune status is, i.e. how vulnerable we are to disease. Now you understand that immunity is not an abstraction, but a counterintuitive concept that can be determined by research. To put it more precisely, we can determine the quality and quantity of the cells in our body responsible for immunity such as: leukocytes (which include neutrophils, lymphocytes, basophils, monocytes, eosinophils) and proteins - immunoglobulins (A, E, G, M). A variety of qualitative and quantitative changes in each of these can lead to immunodeficiency, a condition characterized by a lack of immunity.

But if we have to talk about immunity in practice, here is how to know by secondary signs that the body has problems with immunity:

• frequent and/or prolonged infections, most often these are ENT and respiratory diseases in children and adults;
• recurrent or poorly amenable candidiasis of the skin and mucous membranes;
• persistent infections of the gastrointestinal tract;
• hidden infections and a low temperature without obvious reasons for it.

If you notice any of these signs, consider an immunostimulant. Bioshield offers a wide range of immunostimulants for children and adults. You can choose the most suitable for you and your child from the Biozin range.
