The immune system is essential for human survival. Its main purpose is to defend the body from infectious chemicals, germs, and changes in cells that may make you sick. Without the immune system, you would be constantly falling ill. 

The immune system works by recognising the difference between your body’s cells and ‘alien’ cells and destroying any of the latter that could be potentially harmful. 

Protecting Your Body

As you come into contact with germs from pets, other individuals, and your environment all the time, a healthy and properly functioning immune system lets you go through your daily routine. 

Without a healthy immune system, you could pick up pathogens and infectious diseases more easily, and the consequences could be severe or even fatal. 

The first line of protection for your body is its physical barriers. 

If viruses and bacteria manage to penetrate these barriers, there are specialised cells that will spring into action.

For one, the white blood cells in your bloodstream and main areas of your body can kill and destroy the viruses and bacteria they encounter.

However, there are also times, such as when one has hay fever or autoimmune conditions, when your immune system may overreact and even invade your body’s own cells. 

Reinforcing Your Immune System

It is important to take care of your immune system. Make sure it is strong and healthy so that it will take care of you.

There are a few ways you can protect and strengthen your immune system.

You can eat more greens, stay hydrated and exercise regularly. Read more on how you can strengthen your immune system here.
