Wandering about ways to strengthen your immune system and lifestyle changes to boost your immune system?

The immune system is a defensive system of the body that contains a complex network of cells and proteins. This complex network protects the body of an individual from infectious environmental agents such as microbes and chemicals thus preserving the integrity of the body. When any foreign particle attacks the body, the immune system of the body creates an immune response against that particle which is in the form of innate immunity and specific immunity. Innate immunity provides the first line of defense and responds rapidly to protect the body against infection. Specific immunity involves producing antibodies against a pathogen to destroy it. Another very important role of this system is to keep a record of each infectious particle or microbe against which it has defeated to protect the body to recognize and kill the microbe rapidly if it enters the body later.
