Cardiovascular Responses to Academic Stress in Allied Health Students: A Comprehensive Narrative Review

Abstract

Background: Stress related to studies is a prevalent issue in higher education and a possible cause of physiological changes in the cardiovascular system with lasting effects, particularly for students in allied health who go through a rigorous training program consisting of coursework, laboratory work, and clinical assessments. Objective: To analyze the evidence regarding the cardiovascular response to stress in academics, primarily in the fields of allied health, the main physiological ways, and the factors controlling it that can be influenced. Methods: A narrative review of literature from 2000 to 2025 on student populations under stress from exams or studies and reporting on cardiovascular or related physiological outcomes (for example, heart rate, blood pressure, heart rate variability, cortisol/catecholamines, endothelial function) was conducted using PubMed, Scopus, Web of Science, and Google Scholar. Results: Academic stress is shown across the studies to cause an increase in heart rate and blood pressure, a decrease in heart rate variability, the activation of both the sympathetic nervous system and the HPA axis, and the temporary impairment of endothelial function. Also, during exams, there might be an increase in inflammatory and oxidative markers. The lifestyle habits that are common during stressful situations such as lack of sleep, unhealthy diet, eating more caffeine, and not exercising at all lead to the worsening of these cardiovascular responses. Also, there are indications that certain groups may be more exposed to such conditions (e.g., iron deficiency among females). The studies on stress-related physiological reactions in allied health students are still in the early stages but the findings are already suggesting that the stress levels experienced by this group are either comparable to or higher than those of general student samples. Conclusions: The effect of stress related somehow to the studies on cardiovascular system has been consistently observed in students, and it can be said with certainty that the consequent early exposure of risk to cardiovascular diseases might be the result of repeated stress through the academic cycles. Institutions should take into account the necessity of screening for at-risk students and providing them with multi-component intervention (sleep, nutrition, caffeine moderation, and structured physical activity) as a solution. Longitudinal studies integrating autonomic, endocrine, endothelial, and biochemical markers in allied health students are warranted.
