Do you know how the immune system works and what it takes to help keep it strong? Let's do a simple breakdown of the body's immune system and some tips for giving it some support.
Your immune system function is truly amazing – it has the ability to fight off new infections, and remember all the microbes it has ever fought before. It does so with some very specialized organs, cell and proteins.
White blood cells
These hunt around your body looking for microbes and attacking any that they find.
Antibodies
These are proteins that help white blood cells find and attack microbes.
Complement system
This is a series of proteins that assist white blood cells and antibodies in their defense duties.
Lymphatic system
This is a set of tubes, a bit like veins and arteries. Its roles include being a battleground for fighting microbes and cancer cells, plus managing our fluid levels.
Spleen
This is an organ that filters your blood, removing microbes and damaged blood cells.
Bone marrow
This is where your white and red blood cells originate from.
Thymus
This is another place where blood is filtered, and another source of white blood cells.
Being so complex, it’s not surprising that your immune system function can play up from time to time, or even on a regular basis. The reasons for this can involve too much or too little defense.
Too much defense can range from causing common allergies like hayfever, more serious conditions like peanut allergy, and some potentially lifelong autoimmune diseases where the body attacks itself (eg, psoriasis).
Too little defense, sometimes called immunodeficiency, can result from some inherited diseases, infectious diseases, and treatments that affect the immune system.
If you’re just plain sick of always being sick, getting into some good immunity habits might be just what you need. These are some great ways to boost and strengthen your immune system:
Start with the basics of a healthy lifestyle – a good diet and regular exercise
Maintain good hygiene – including taking care of your teeth
Get enough sleep – lack of sleep makes you more likely to get sick. Check out this article on how to improve sleep quality.
Manage stress – a little stress is okay, but too much can lower your natural defenses, so don’t forget to make time to relax
Avoid people who appear sick – look out for runny red noses!
Go for regular check-ins with a trusted health professional – prevention is better than cure! Read our tips for finding the right health professional for you.
