Final answer:
Disturbances and stress play vital roles in the emergence and progression of psychophysiological disorders and immune system weakening, with chronic stress being particularly detrimental.
Step-by-step explanation:
Both disturbances and stress are thought to play critical roles in the onset and progression of psychophysiological disorders and in the weakening of the immune system. Chronic stress, in particular, has a lasting impact, inhibiting immune responses and increasing the vulnerability to various diseases. Stress activates the physiological system responsible for acute stress responses, but when activated chronically, it can lead to deleterious health effects, including cardiovascular disorders and asthma.
As described by researchers, stress-related diseases arise from prolonged activation of this system concerning mundane concerns like finances, relationships, and job performance. The field of psychoneuroimmunology is investigating how prolonged stressors contribute to the suppression of both innate and adaptive immune responses and how this suppression is linked to the increase in disease prevalence.
