Whenever someone feels ill, people will start talking about their immune system. But what exactly is natural immunity, and how does it work to protect us?
Your body’s immune system is the inbuilt, complex network of cells and organs which help protect you from infection. If a virus, bacteria, or parasite invades your body, your immune system fights back to protect you and get you back to full health.
The clever thing about immunity is that it learns and adapts. The first time you are exposed to a specific infection, your body’s immune cells learn exactly how to see the infection off. The body will always remember this first episode and will store the memory for the rest of your life. If you ever come into contact with that same infection in future, your body will know what to do (even if it’s decades later). This is what we mean by being immune to an infection.
Your body has two sets of defensive mechanisms, one called ‘innate immunity’ and another called ‘adaptive immunity’.
The immune system is more complex and clever than we imagine!Shop our Vitamins & Supplements range.
