Final answer:
Chronic stress has been linked to the suppression of NK cells, thus inhibiting the body's ability to fight off diseases. This field of study, known as psychoneuroimmunology, is still new but holds great potential in providing advances in our understanding of immune system function. Short-term stress, however, can enhance the body's immune response.
Step-by-step explanation:
Stress has indeed been linked to the suppression of NK cells, also called Natural Killer cells, which play a vital role in the immune system's defense against diseases, especially viral infections and certain types of cancer. Under situations of chronic stress, the body's ability to activate these cells can be compromised, leading to immunosuppression. This has been observed in occurrences like extended caregiving, prolonged work stress, or significant life changes, leading to a decrease in the body's ability to ward off diseases.
This phenomenon is also known as psychoneuroimmunology, a relatively new field that studies the interaction between psychological processes and the nervous and immune systems. Deeper understanding in this area can potentially revolutionize our comprehension of diseases and how to fight them.
Remember, short-term stress can enhance innate immune responses, however, chronic stress significantly reduces immune response and is not good for one's health.
