The Human Immune System: 5 Interesting Facts


More than any year in recent memory, 2020 has reminded us how important it is to have a healthy immune system. With the coronavirus still surging, you'll want to take steps to help your immune system fight off illness. At its core, the human immune system is a combination of cells, tissue, and organs that work together to fight off invading germs. Though most people are aware that the immune system is a critical component of good health, there is plenty about this system that isn't as well-known. Here are five interesting facts about the immune system.

White Blood Cells Are Crucial

In your immune system, white blood cells play an incredibly important role. They are what initially recognizes pathogens, alerting your body to begin its defense against the intruders. A particular kind of white blood cell, called lymphocytes, helps your body remember certain pathogens. This allows your body to more vigorously fight off the pathogen when it enters your body the next time.

Immune System Causes Allergic Reactions

When allergies cause a runny nose or itchy eyes, it's actually not exactly because of the allergen. Rather, it has more to do with your immune system misidentifying the allergen as a dangerous pathogen and then initiating a physical response.

Stress Can Reduce Immune Health

Stress causes the body to produce more cortisol, which is bad for the immune system. To reduce stress, there are many routes you can take, such as exercise, meditation, yoga, and seeing a therapist.

Immune System Can Attack Itself

Autoimmune diseases cause the immune system to attack its own beneficial cells. Multiple sclerosis and rheumatoid arthritis are two of the better-known autoimmune diseases.

Vaccines Are Highly Compatible with Immune System

A vaccine triggers your immune system to start creating antibodies against the pertinent pathogen. As the coronavirus vaccine becomes more widely available, it's important to remember that the vaccine is a friend to the immune system.
