The immune system of your body is strong enough to fight infections and viruses. And to make your immunity stronger, you should do exercise on a regular basis and eat well.
Immune system booster foods – Oranges
Oranges are rich in vitamin C which boosts body’s defences in a number of ways. First, it promotes the production of white blood cells and antibodies which both help your body fight viral infections. Secondly, vitamin C is an antioxidant which means that it protects the cells of your body and your immune system from free radicals (harmful by-products that are released when your body uses oxygen).
