Depression increases your risk of a number of diseases and other conditions by, for example, increasing levels of stress hormones such as cortisol or adrenaline. Depression can affect the immune system, making it harder for your body to fight infection. Vaccinations are even less effective in people with depression.
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.
