Chronic stress has a detrimental impact on immune function, leading to increased susceptibility to infections and diseases. When stress persists, the body produces higher levels of cortisol, which can suppress the immune response and reduce the effectiveness of immune cells. Over time, this can hinder the body's ability to fight off pathogens, resulting in longer recovery times and an increased risk of chronic illnesses. Learning stress management techniques, such as mindfulness and relaxation exercises, is crucial for maintaining a healthy immune system and overall well-being.
