Natural ways to Boost Immune System

In a hurried pace of life, you might consider your immune system for granted. Our immune system fends off the diseases and protects from all kind of infections. A strong innate immune response can considerably reduce the odds of getting sick. Nutritionists and health experts often points out how important is to maintain a good immunity. Let’s understand, how the immune system works.

How does the immune system gets activated?

An immune system gets activated by numerous substances but the body doesn’t recognize it. These can be understood as antigens. Antigens are substances which cause an immune response in the body by identifying substances in or markers on cells. In turn, your body produce antibodies to fights against these antigens, or harmful substances and tries to eliminate them out. Few antigens are proteins on the surface of bacteria, fungi or viruses. When the antigens attack the body, they get attached to special receptor cells in the immune system resulting a whole series of processes.  

The cells in your body also has certain proteins on their surfaces. But those proteins generally don’t trigger the immune system to fight the cells. Sometimes the immune system mistakenly identifies the very own cells as foreign bodies. It further attacks healthy and harmless cells in the body and this response causes auto-immune diseases.

Immune structure has two subsystems namely innate and acquired (adaptive) immunity. Both of them are closely linked and work together to protect the body from harmful pathogens.  The innate immunity provides self-defense against germs and substances, so it’s also known as non-specific immune system. It fights using natural killer cells and phagocytes in the body. Main function is to fight against germs that may enter through the skin or digestive system.  

The acquired or specific immunity creates antibodies and uses them to specifically fight certain pathogens that the body has previously encountered with. This is also known as learned or adaptive immune response. Because the immune system is learning and adapting, how the body can fight against bacteria or viruses that changes over time.
