Final answer:
Chronic stress can weaken the immune system by decreasing its ability to initiate inflammation and interfering with the formation of antibodies.
Step-by-step explanation:
Chronic stress can lead to a decreased ability of the immune system to initiate inflammation and interference with the formation of antibodies. When the body is under chronic stress, the persistent secretion of steroids, such as cortisol, can weaken the immune system. Cortisol has been shown to weaken the immune response by suppressing inflammation and hindering the production of antibodies, which are essential for fighting off infections. This can make individuals more susceptible to illnesses and infections.
