Effects of Chronic Stress on Neuroendocrine and Immune Function: Clinical Implications for Early Intervention in Psychosomatic Disorders

Abstract

Chronic stress is increasingly recognized as a major physiological and clinical factor in the development of psychosomatic disorders. Prolonged
exposure to psychological or environmental stressors can disrupt the body’s adaptive regulatory systems, particularly the hypothalamicpituitary-
adrenal axis, autonomic nervous system, and immune-inflammatory pathways. This paper examines the effects of chronic stress on
neuroendocrine and immune function and discusses the clinical implications for early intervention in stress-related psychosomatic conditions.
The review highlights how persistent stress may alter cortisol secretion, impair feedback regulation, increase sympathetic activity, reduce
parasympathetic balance, and contribute to immune dysregulation through pro-inflammatory cytokine activity and glucocorticoid resistance.
These biological changes may present clinically as fatigue, sleep disturbance, pain sensitivity, gastrointestinal symptoms, mood changes, and
other medically unexplained or stress-aggravated complaints. The paper further emphasizes that psychosomatic symptoms should not be viewed
as purely psychological but as possible indicators of underlying mind-body dysregulation. Early identification of stress-related physiological
patterns may support timely intervention through integrated approaches such as cognitive behavioral therapy, mindfulness-based strategies,
sleep optimization, physical activity, nutrition support, and structured clinical monitoring. Overall, the paper argues that early intervention in
chronic stress can reduce symptom burden, improve quality of life, and prevent progression toward more complex psychosomatic disorders.
