How does stress affect the immune system?

Stress can have a significant impact on the immune system, primarily by suppressing the immune response. When the body experiences stress, it releases stress hormones such as cortisol and adrenaline. These hormones are part of the body's natural fight-or-flight response and can lead to various physiological changes.

Cortisol, in particular, has been shown to inhibit the function of immune cells, such as T-cells and B-cells, which are critical in fighting infections and diseases. This suppression can lead to a decreased ability to respond to pathogens, thereby making the body more susceptible to infections and illnesses. Chronic stress can result in prolonged exposure to these hormones, further weakening the immune system and increasing the risk of various health issues, including autoimmune conditions and infections.

Understanding the relationship between stress and immune function is crucial, as it highlights the importance of stress management techniques for maintaining a healthy immune system and overall well-being.
