An observational, analytical, cross-sectional, and quantitative study was conducted on 69 employees. Total serum cortisol was measured via chemiluminescence in fasting morning samples (reference: 110\u2013692 nmol\/L). Burnout was assessed using the Maslach Burnout Inventory\u2013General Survey (MBI-GS). A total of 96.6% of participants fell within the normal range for serum cortisol. MBI-GS dimensions reported mean scores of: exhaustion 1.54 \u00b1 1.17, cynicism 0.93 \u00b1 0.89, and professional efficacy 5.60 \u00b1 0.60. High exhaustion prevalence was 16.9%, high cynicism 6.8%, and low efficacy 3.4%. Profile classification showed 67.8% \u201cengaged,\u201d 13.6% \u201coverextended\/worn-out,\u201d and 5.1% with \u201cburnout.\u201d No significant association was found between cortisol and burnout dimensions: exhaustion (r = 0.069, p = 0.605), cynicism (r = \u22120.135, p = 0.309), and professional efficacy (r = 0.044, p = 0.742). Mean cortisol comparisons between high and low dimension groups showed no statistically significant differences (p &gt; 0.05). The study documented a low prevalence of established burnout and an absence of significant association between morning serum cortisol and MBI-GS dimensions, suggesting a relatively healthy work environment; however, the prevalence of high emotional exhaustion warrants preventive interventions. Multilevel organizational strategies like workload management, job stability, role clarity, and psychosocial support are recommended for worker mental health protection.<\/jats:p>","DOI":"10.3390\/ijerph23080995","type":"journal-article","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T17:01:46Z","timestamp":1785344506000},"page":"995","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Association Between Morning Serum Cortisol and Burnout Syndrome in Healthcare Workers in Boyac\u00e1, Colombia: A Cross-Sectional Study"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3018-8759","authenticated-orcid":false,"given":"Juan Pablo","family":"Carvajal","sequence":"first","affiliation":[{"name":"Carvajal Laboratorios IPS SAS, Tunja 150003, Boyac\u00e1, Colombia"},{"name":"School of Business Administration, Faculty of Business Administration, Universidad de Manizales, Manizales 170004, Caldas, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0723-3240","authenticated-orcid":false,"given":"Fred Gustavo","family":"Manrique-Abril","sequence":"additional","affiliation":[{"name":"School of Medicine, Faculty of Health Sciences, Universidad Pedag\u00f3gica y Tecnol\u00f3gica de Colombia, UPTC, Tunja 150003, Boyac\u00e1, Colombia"},{"name":"Faculty of Nursing, Universidad Nacional de Colombia, Bogota 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"456","DOI":"10.62438\/tunismed.v104i03.6332","article-title":"The prevalence and associated factors with burnout among healthcare workers in Morocco: A systematic review","volume":"104","author":"Ouabrk","year":"2026","journal-title":"Tunis.
