Chronic stress leads to sustained high levels of cortisol, a hormone released by the adrenal glands in response to prolonged stress. Elevated cortisol can interfere with the normal functioning of the immune system by reducing the production of cytokines, which are crucial for cell signaling in immune responses. This suppression can leave the body more vulnerable to infections and diseases, as the immune system is less able to identify and combat pathogens effectively.
Additionally, chronic stress is linked to increased inflammation, which can exacerbate various health issues such as heart disease, diabetes, and autoimmune disorders. When the body remains in a state of heightened alertness due to stress, it may also contribute to unhealthy behaviors, such as poor diet, lack of exercise, and inadequate sleep, further compromising overall health. Therefore, managing chronic stress is essential not only for maintaining immune function but also for promoting long-term physical and mental well-being.
