Age-associated alterations-including diminished thermal perception, impaired autonomic responsiveness, reduced thermogenic capacity due to sarcopenia, and decreased cardiovascular adaptability, exacerbate the vulnerability to hypothermia. Concomitant comorbidities and polypharmacy further compromise thermal homeostasis in geriatric patients. Anesthetic agents compound this risk by lowering the thresholds for vasoconstriction and shivering and attenuating the magnitude of thermal responses. Consequently, geriatric populations are predisposed to significant perioperative temperature decline, particularly in cooler operating room (OR) environments. Intraoperative hypothermia is associated with an increased incidence of adverse outcomes, including increased cardiac events, surgical site infections, coagulopathy, protracted pharmacodynamic effects, extended recovery, and hospitalization duration. Although recent investigations suggest a diminished incidence of hypothermia due to minimally invasive surgical techniques and enhanced temperature management protocols, the intrinsic susceptibility of the aged thermoregulatory system persists. Effective temperature management requires precise core temperature monitoring and maintains appropriate OR temperatures. Furthermore, the implementation of multimodal warming strategies, including passive insulation, active warming modalities, warming of intravenous fluids, and prewarming before anesthesia induction, is critical. Therefore, a comprehensive and proactive thermal management approach is essential in mitigating hypothermia-related risks and optimizing perioperative outcomes in the geriatric patients.<\/jats:p>","DOI":"10.17085\/apm.25294","type":"journal-article","created":{"date-parts":[[2025,7,31]],"date-time":"2025-07-31T05:15:42Z","timestamp":1753938942000},"page":"189-199","update-policy":"https:\/\/doi.org\/10.17085\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Cold
