What is the immune system for?

It’s for fighting against diseases and other invaders that threaten your health.

How does the immune system work?

To fight invaders, the immune system works through a complex network containing different types of

  • immune cells, each type performing different functions. For example, macrophages swallow invaders.
  • Immune substances such as antibodies
  • Organs such as lymph nodes
  • Messengers for cells to communicate with each other

All these work together in order for the immune system to function.

To be effective, the immune system also shares an interdependent relationship with other systems of the body:

  • Circulatory
  • Skin
  • Endocrine
  • Nervous
  • Musculoskeletal
  • Reproductive
  • Respiratory

  1. Hi,

    I’ve heard a lot of good things about the immune system and seems like it’s one of the best ways to prevent illness from happening in the first place.

    I’m very interested in how to boost your immune system naturally.

    You mentioned to eat less meat. Do you mean it’s best to not eat at all? Or just eat a little less? If so, how much?

    Thanks for sharing!

    Cheers,
    Anh

    1. Hi Anh! It would be great for your health if you could stay away from meat altogether. But if you’re not happy being a total vegan, it’s perfectly fine. Just keep meat intake at a minimum daily. Replace whatever meat you reduce with fruits and vegetables.

      Here’s some research to help you make an informed decision:

      In research published in March 2016 in the European Journal of Clinical Research, over 20 years of follow up with more than 11,000 people showed that a once-a-week meat diet or vegetarian diet DID NOT reduce the risk of breast, lung, or prostate cancer.

      In June 2016, a review of past studies on this subject published in Food and Chemical Toxicology revealed that high intakes of red meat and processed meat increases colorectal cancer risk. Processed meat like sausages contribute to diabetes and cardiovascular disease risk.

      The link between processed meat and certain diseases is more apparent. If there’s anything to eliminate immediately, it would be hotdogs, ham, sausages, bacon and any other preserved or processed meats.

  2. So it sounds to me like veganism is the key to strengthening the immune system, am I right? You said to cut back on meat, and dairy based products so that’s what the conclusion that I am coming up with. I haven’t eaten meat in months but dairy products are hard to stop eating. I will try to eat more vitamins of different types more often now, thanks for the post!

    1. Hi Jose! It’s difficult, which is why I haven’t said eliminate them completely. As long as you’re cutting down from your current consumption, it’s a good start.

      While a vegan diet is ideal, it takes the right knowledge to eat right too. Be sure to do the vegan diet right by

      taking vitamin B12

      Eating many different fruits and vegetables

      Ensuring that you obtain enough iron from the fruits and vegetables you eat

      Do not resort to vitamin pills as they can do more harm than good in the body.

  3. Hi,

    Great article and a lot valuable information you provide! For me the immune system is still some abstract idea, because it’s active through the whole body instead at one place like the stomach or heart. Or am I wrong? I like take cold showers in the morning as they say it would be good for the immune system. I don’t know why though. Can you maybe explain that to me as the health expert?

    Thanks in Advance!

    1. Amazingly, the effects of cold showers on immunity have been scientifically tested. In 2013, a group of researchers put some volunteers through meditation, immersion in cold water, and breathing techniques. Compared to volunteers who didn’t do any of these, they had less pro-inflammatory substances in their bodies and showed less flu symptoms.

      Why does this happen? When subjected to such treatment, your nervous system produces more epinephrine, a hormone. This leads to more anti-inflammatory substances and less pro-inflammatory substances in your body.

      Thanks for bringing this up and showing us how closely linked our other systems are with the immune system!
