People often say that health is wealth, this is not just a saying but an important message that we should heed. Humans are born with the inclination to make thoughtful decisions about things that matter the most. What is more important than human health in this regard? The human body consists of many systems, each of which performs a specific function to keep the body healthy. The immune system is one of the most crucial body systems. Just like a guard who protects your property, the immune system shields your body against foreign invaders including bacteria, insects, fungi, toxins, viruses, etc.
Types of the immune system
There are mainly two types of the immune system:
- Innate immune system (the first-line defense)
- Adaptive immune system (learn to identify enemies)
Functions of the immune system
The role of the immune system is as important as the heartbeat, as it impedes the invasion of any alien bodies into human systems. A brief list of roles that the immune system performs in the body is as follows:
- Strategic decisions
- Identify and memorize its enemies
- Kill enemies
- Cause inflammation
- Fighting worms
- Produce antibodies etc.
Factors that depress the immune system
There are a few factors that slow down the normal functioning of the immune system. Some of them are listed below:
- Excess weight
- Environmental toxins (smog, smoke, excessive alcohol)
- Poor Diet
- Older age
- Chronic disease
- Lack of rest and sleep.
In such cases boosting the immune system is of critical significance to keep it healthy throughout the year. The best trick is to improve your diet and take sufficient rest. Another crucial factor that strengthens your immunity is top taking immunity vitamins.
Vitamin deficiencies can pose a serious health risk. It is therefore important to take those vitamins in diet or in pills. Some of them are discussed below:
A fat-soluble vitamin, vitamin A is essential to our health. It functions for both our adaptive and innate immune systems. It plays a major role in the production of B-cells and T-helper cells. Vitamin A deficiency reduces antibody production and thus directly affects antibody-mediated response.

Vitamin B12 is a water-soluble vitamin. It plays a key role in the production of red blood cells and supports immune system health through fighting infection risks and modulating immune function.
