What Causes Immune Deficiency? How To Boost Immune System?

Our body’s defense squad, the immune system, is like a shield that protects us from invaders like viruses and bacteria. It helps keep us healthy and fit, with no diseases, and no infections! But when this shield is weakened, it leaves us open to illnesses. We get more prone to infections, even if they are small. For instance, you can get attacked by cold and cough more frequently as compared to your peers. Some people even tend to fall sick as soon as there is a slight change in the weather. This is a bad sign and has to be solved.
