How does chronic stress affect the overall efficacy of the human immune system?

Answer

It floods the body with cortisol, which suppresses immune effectiveness over time

Chronic stress triggers the sustained release of cortisol, a hormone that, in high and persistent levels, functions as an immunosuppressant. When the body is under constant stress, this hormonal response diverts resources and diminishes the effectiveness of immune cells. Constructive stress management is therefore considered a direct intervention to reduce disease vulnerability and maintain a functional immune system.
