The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is really a collection of reactions and responses that the body makes to damaged cells or infection.ancer can weaken the immune system by spreading into the bone marrow. The bone marrow makes blood cells that help to fight infection. Weakening of the immune system happens most often in leukaemia or lymphoma.
How stress weakens the immune system. When long term stress becomes chronic, many systems in the body are affected. Chronic stress results in high levels of cortisol and other corticosteroids circulating in the blood for a long period of time.. It lowers the immunity of those who otherwise might have a healthy immune system. According to Dr. Mary Meagher, âpeople exposed to chronic social conflict experience high levels of stress and consequent dysregulation of the immune system, thereby increasing vulnerability to infectious and autoimmune diseaseâ.
