26 Effective Home Remedies To Boost Your Immune System August 3, 2016

Is it possible to make your immune system stronger? Well, the answer is yes. Immunity fortifies the body against external invasion by microorganisms, allergens, and parasites. People suffering from low immunity are prone to fall sick frequently and are susceptible to fatal diseases. That is why strengthening the immune system is a prerequisite for keeping various ailments at bay.

How Does the Immune System Work?

The immune system performs the function of defending our body against the disease causing micro-organisms. Failure of the immune system to perform its function effectively results in increased susceptibility to diseases and infections. The immune cells play a major role in preventing the entry of pathogenic bacteria and viruses into the body. These cells comprise of lymphocytes or T-cells which directly fight invading molecules and B-cells which produce antibodies that respond to harmful molecules, facilitating their removal by other immune cells. The immune system also contains phagocytic cells such as macrophages and neutrophils, which eliminate the debris created from the destruction of harmful cells and tissues at the site of infection. Impairment of any of these functions can weaken your immune system [1].

Prevention is better than cure and, therefore, it is important that we maintain a strong immune system. Our immune system requires balance and harmony to function efficiently. It can be efficiently improved by incorporating a few changes in our diet and lifestyle.
