Immune System Facts, Information and Resources

You may wonder why some people seem to catch cold after cold, while others sail through cold and flu season unscathed. The system in the body responsible for fighting off bacterial, viral, and other infections is the immune system. If you catch colds easily, you may want to think about strengthening your immune system. A robust immune system can crush invading pathogens before they can manifest illness.

The immune system works all year long, not just during the cold and flu season. A pathogenic organism can invade the body at any time, and the immune system needs to be prepared to stop it in its tracks. The human immune system has been designed by evolution to keep us healthy. But when it fails, a specialist in immunology can apply immunotherapy techniques to help improve immune system function.

The Body’s Natural Defense System

The immune system is the body’s innate defense system. It’s an elaborate and specialized network of cells, tissues, and organs that work together to defend the body against infectious invaders. Those infectious intruders can include viruses, bacteria, parasites, even types of fungus, all of which have the potential to make you sick. These pathogens are everywhere in our environment. 

A robust and vigilant immune system protects you by first creating a barrier that stops the invaders from entering the body. If one slips by the barrier, the immune system calls white blood cells and other chemicals and proteins into action to attack and destroy these foreign pathogens. Ideally, they find and get rid of them before they can reproduce. If it fails at this level, the immune system fires even higher to destroy the intruders as they multiply.

The immune system can recognize millions of individual pathogens. And it has the capacity to produce what it needs to eliminate nearly all of them. When the immune system is working correctly, this intricate defense system can keep threats to health, ranging from cancer to the common cold, in check.

The Immune System Can Break Down

The immune system can mistakenly identify a substance as being harmful when it’s not. When the immune system launches to fight these substances it mistakenly sees as invaders, such as pollen or pet dander, you can have an allergic reaction.

Additionally, your immune system might be lacking the ability to fight off every invader. Despite the elaborate and intricate design, the immune system can break down at times. These diseases that evade the immune system may be challenging to control, but specific lifestyle considerations are critical.

Factors such as unhealthy eating, a  sedentary lifestyle, not getting sufficient quality sleep, and undergoing chronic stress can all weaken the immune system. Bacteria, viruses, or toxins can overwhelm the body when the immune system is depleted, resulting in illness and disease.

A  holistic approach to boosting the immune system and supporting protection from disease may be the best option, as there is no single approach. Professional immunologists can do an in-depth assessment of immune functioning and recommend steps to correct function and bring the immune system back into balance.
