Extreme heat causes record mortality and health crises in Spain and Mexico
Extreme heat is causing significant health crises across several regions. In Spain, the MoMo monitoring system estimates that 5,232 deaths attributable to high temperatures have occurred so far this year, marking a historic high. The majority of these fatalities involve individuals over 65, particularly those over 85, with women accounting for 60% of the total. In the Community of Madrid, over 260 heat-related deaths have been recorded this summer.
Medical professionals report that emergency services are being strained not only by heatstroke but by the exacerbation of chronic cardiovascular, respiratory, and renal conditions. Vulnerable populations, including children and the elderly, are at highest risk. In Querétaro, Mexico, health authorities reported four cases of heatstroke and one death between March and August 2026.
In Guatemala, health experts warn that high temperatures in the central highlands can reach 30 degrees Celsius, necessitating strict hydration and heat avoidance to prevent symptoms like confusion, vomiting, and extreme weakness.
