Quick Facts: An Insight into the Immune System

Whether you want to learn more about your body or wish to understand the complex journey it takes to fight off illnesses, you’re in the right place. Read on to discover some quick facts about your immune system and all that it does.

What Is The Immune System?

Your immune system is a super important part of your body. It is made up of different organs, cells, and proteins. These all work together to protect you from harmful invaders like bacteria, toxins, fungi, and viruses.

Facts About The Immune System

Fact #1: Vaccines Educate It

Your immune system works by “learning” which foreign invaders to fight off. Vaccines use this to their advantage.

When you are given a vaccine, your immune system will start to produce antibodies against it. This means that when your body encounters a specific invader in the future, it will know to fight it off.

Fact #2: It Knows The Difference Between “Good” And “Bad” Germs

It’s a common misconception that all germs are bad. However, this isn’t true. Many microbes live in your body and actually benefit from its function!

“Good” bacteria helps to provide a defense against “bad” bacteria while also providing your body with nutrients. A fully functioning immune system will be able to identify the differences between “good” and “bad” germs, allowing access to the beneficial ones.

Fact #3: It Can Be Affected By Stress

Research has shown that stress can lead to increased levels of cortisol. Cortisol is a steroid hormone that plays many important roles in the body. However, too much of it might affect your immunity. This suggests that stress might lead to poor performance of the immune system.

Fact #4: Vitamin D Is Its Friend

We’re often told about how important vitamins are for the normal functioning of our bodies. It’s no surprise to learn that the immune system also benefits from obtaining sufficient amounts of certain vitamins.

Vitamin D is one of the vitamins that are most commonly linked to the function of your immune system. Research has shown that it supports your immune system/natural defenses (EFSA, 2010).

Obtaining Vitamin D: The frustrating thing about vitamin D is that it cannot be found in many foods. Instead, your body produces it when exposed to strong enough sunlight. As this isn’t possible to come into contact with all year round, we highly recommend taking vitamin D supplements to safeguard your intake.

Fact #5: Allergies Signal False Alarms

An allergic reaction occurs when your body responds to a harmless allergen that it thinks is a threat. From cold-like symptoms to hives, there are many symptoms of allergic reactions to be aware of.

Fact #6: It Can Attack Itself

Did you know that the immune system can attack itself? Autoimmune diseases occur when your immune system fights against its own healthy tissues. This confusion can lead to a whole range of serious issues, including diabetes and arthritis.

While it’s not always perfect, your immune system does a fantastic job of protecting your body against harmful invaders. We hope you found these facts interesting!
