How Your Immune System Works

your_immune_systemWhen somebody says “immunity” or “Oh! Your immune system must be down” we can assume that they mean our body’s defences are low, and therefore we are more susceptible to illnesses and disease.

But how this system works often goes under the radar, with not many people really understanding how they can boost it up, or why boosting their immune system is important.

However, understanding the way that it works can lead you to make better choices regarding your diet and lifestyle, and make you feel a lot better too!

The immune system is a great defender of our health.

By this, I mean that it is the bodies’ mechanism for keeping diseases and illnesses at bay.

Of course, if everyone’s immune systems worked at their optimal level, we would never get sick.

Unfortunately, diet and lifestyle choices mean that a lot of the time, the mechanism that protects us is unable to work at its optimal level, and because of this it lets pathogens (the nasty bacteria, virus or organisms that make you sick) slip past it’s defences causing you to become ill.

When pathogens slip past it’s defences, the immune system is also the system responsible for making you feel well after being ill.

Again, if your immune system is weak, this process will take a lot longer, even for simple illnesses like colds.

But how does it work?

Well, when a pathogen enters your body, its main aim is to reproduce itself.

At this point the pathogen is a teeny tiny cell, and it needs to take over your body and make you sick to survive.

Fortunately for us however, there are cells that make up part of our immune systems’ called macrophages.

These macrophages pretty much patrol our bodies’ looking for anything out of the ordinary, or an “intruder”.

A majority of the time these “intruders” are pathogens, however, sometimes things such as pollen or anything that is an allergen can be identified as such.

When they find these pathogen cells, they immediately aim to destroy them.

If they are unable to destroy them, then the immune system goes into its secondary phase of producing extra T and B cells.

At this point you will probably feel the illness taking a hold, but they do work to fight it as soon as they can, and collect data so that the same bacteria will not be able to harm you again.

Pretty fantastic right?
