The feeling of a mental breakdown may seem like the worst of all but what is even worst is having to suffer through something so not in your control which breaks your body and makes you question all your life decisions about health. Your body is something to be respected and well maintained, but what to do when some uninvited guests visit the immune system and start messing with its healthy working?
Viruses from the outside environment enter our bodies, and while some may cope with them because of a strong immune system, some fall prey to them and fall sick. When an outside virus enters our, it forms antibodies to beat it, but sometimes the process fails for various reasons, the topmost being a failed immune system which is very common. Ever since we can stand and eat on our own, our parents provide us the healthiest they can; they make us eat less junk and more home food. In a bone structure, our backbone may be the backbone of our body, but it is the immune system that holds it together.
Falling sick may not always mean something very above the line but also can be something as simple as the cold flu. The cold flu, in layman terms, is just a cold you know where you have a running, red nose, distorted speaking, difficulty in breathing, and no sense of smell. It may last a few days and can be cured with a course of antibiotics.

What can a strong immune system do?
A healthy and carefully built immune system is your wall of defense against any outside virus trying to enter or has already entered your body, and no, you must nourish it. From school days, we have had chapters of a healthy immune system and how to keep a healthy diet or what a healthy diet constitutes, but how many of us do believe it or act upon it? Fair to say, not even a handful, we keep delaying providing our body the nutrients it needs regularly.
