Overview

• US temperatures nearing 40°C drive the CDC to stress hydration, avoidance of peak sun hours and lightweight, loose-fitting clothing.
• Spanish SUMMA 112 teams handle about 3,500 daily heat-related calls and are deploying rapid cooling methods and intravenous serums for severe cases.
• UK experts warn that altered behaviour such as confusion, slurred speech or irritability can signal heatstroke and demands immediate action.
• Young children, seniors and people with chronic health issues face heightened risk and should watch for symptoms like dizziness, nausea and dry skin.
• Climate scientists warn that human-induced warming will make heatwaves more frequent, intense and prolonged, intensifying future heatstroke risks.
