The correct answer highlights the well-documented understanding of how stress affects the body. In health psychology, it is recognized that stress can lead to a variety of physical health problems due to its influence on the immune system. When a person experiences stress, the body undergoes a series of biological changes, including the release of stress hormones such as cortisol. Chronic elevation of cortisol can suppress immune function, making an individual more susceptible to infections, autoimmune diseases, and other health issues.

Additionally, prolonged stress can lead to various conditions such as cardiovascular disease, metabolic disorders, and gastrointestinal problems. This understanding emphasizes the interconnectedness of mental and physical health, aligning with the biopsychosocial model in health psychology that views health as a product of biological, psychological, and social factors. This model underscores the importance of managing stress not only for mental well-being but also for maintaining physical health.
