Chronic stress can have a detrimental impact on the immune system, leading to a higher susceptibility to infections and illnesses. Prolonged stress responses can inhibit the function of immune cells, impairing the body's ability to fight off pathogens. Additionally, stress increases the production of cortisol, which when elevated can suppress immune function. Chronic stress may also lead to unhealthy coping mechanisms like poor diet and lack of exercise, further weakening the immune system. Addressing and managing stress through relaxation techniques, mindfulness, or physical activity can significantly enhance immune resilience.
