Geriatric specialist Gregorio Jiménez Díaz explains the challenges older adults face in maintaining a stable body temperature. As people age, their thermoregulation mechanisms begin to fail, making them more vulnerable to heat and cold. Jiménez Díaz, from the Príncipe de Asturias University Hospital and the Spanish Society of Geriatrics and Gerontology, highlights this decline as a key aspect of care for the elderly. This diminished ability to regulate temperature requires increased attention, particularly during extreme weather conditions. Understanding these physiological changes is crucial for protecting the health and well-being of senior citizens. The specialist’s insights emphasize the need for proactive measures to support thermal comfort in an aging population.
