From pollution and poor diet to lack of sleep, various factors can hinder our body’s ability to ward off illnesses. The immune system is our body’s defense mechanism, helping fight off harmful bacteria, viruses, and other pathogens. It’s like the body’s own security team, and keeping it strong is crucial.
