How to tell if you have a weak immune system If you have been experiencing persistent and recurring infections, you may have a weak immune system. Some causes of a weak immune system like age and certain diseases are out of our control, but there are still various factors that you can control. It is scientifically proven that unhealthy habits like not getting enough sleep, a poor diet, and stress directly correlate with a weakened immune system.
What is immunity? Our immune systems are our body’s defense against external and potentially harmful bacteria. Doctors and health care professionals highlight time and again the importance of a healthy immune system. It is a system that gets stronger as we grow from infants, protecting our bodies from bacteria and disease. This macrophage is one of the cells of our immune system When our bodies produce specific cells that resist a particular disease, we can say that we are immune to it.
The immune system is a complex defense network that protects the body against potentially harmful agents and can respond to millions of antigens. Through orchestrated reactions, that is, the immune response, the immune system can recognize and remove pathogens. It serves to distinguish “non-self” from “self” and acts to ensure tolerance of self, food, and other environmental components and commensal bacteria inherent in the body. However, any mistake or alteration in tolerance pathways may lead to a disordered immunological process.
