Overview
- EsSalud warned that adults over 65 and people with cardiovascular disease face heightened danger in temperatures above 30°C due to reduced thirst perception and lower body water.
- Doctors outlined early dehydration signs that often precede strong thirst, including dark urine, dry mouth, persistent fatigue, mild headaches and reduced concentration.
- Clinical guidance distinguishes insolación from heatstroke and instructs immediate actions: move to a cool, shaded place, remove excess clothing, cool with water or cold compresses to neck, armpits and groin, ventilate and call emergency services.
- Health advisories highlight children, older adults, outdoor workers and those in hot indoor settings as higher-risk groups, urging regular fluid intake and activity timing to avoid peak sun hours.
- Cardiologists cautioned that dehydration can worsen arrhythmias, hypotension or heart failure, especially in patients on diuretics, recommending 1.5–2 liters of fluids daily, cool environments and no medication changes without medical advice.
