Final answer:
The constant stress and frequent sickness experienced by Srinivas is known as psychophysiological disorders, where prolonged stress causes cumulative damage to the body and can lead to serious health issues.
Step-by-step explanation:
The wear and tear on Srinivas's body caused by his constant stress from attending college full-time, working part-time, and participating in on-campus groups is known as psychophysiological disorders. This concept stems from the idea that prolonged stress can lead to cumulative damage on the body’s tissues and organs, potentially resulting in various illnesses. As the body attempts to cope with ongoing stress, it may enter a stage of exhaustion where it is no longer able to adapt to the stressor, leading to physical wear and potentially serious health consequences.
Stress researcher Robert Sapolsky has highlighted how the physiological system evolved to handle acute physical emergencies, but long-term activation due to chronic stress can result in stress-related diseases. Additionally, the concept of general adaptation syndrome described by Hans Selye elaborates on the three-phase process of an initial jolt, subsequent readjustment, and later depletion of physical resources, which can set the stage for serious health issues, including those related to the cardiovascular system.
