According to psychoneuroimmunology, the starting point in patient care emphasizes the impact of what on health?

• A. Stress
• B. Diet
• C. Sleep
• D. Exercise

Answer: (A)

In psychoneuroimmunology, the starting point is recognizing how psychological stress drives the brain–neuroendocrine–immune cascade. Stress activates the HPA axis and the sympathetic nervous system, releasing cortisol and catecholamines that modulate immune cell function and cytokine production. Over time, this can alter susceptibility to infections, wound healing, and inflammation, influencing health broadly. So, addressing stress and teaching coping strategies can improve immune function and overall health outcomes. Diet, sleep, and exercise matter too, but the initiating factor in this framework is stress.
