Heat waves are becoming more frequent and intense. Why classic crisis preparedness must be expanded to include heat protection — and what you can do concretely before the next summer.
Crisis preparedness is traditionally associated with cold, darkness, and scarcity — winter blackout, heating failure, missing warmth. But climate change is inverting the risk profile: heat waves are the underestimated catastrophe of our time.
Heat Kills — More Than All Other Natural Disasters Combined
This isn't an exaggeration. The European Environment Agency documents: in Europe, more people die from extreme heat than from floods, storms, and earthquakes combined.
The 2003 heat summer alone killed over 70,000 people in Europe. In 2022, an estimated 4,500 people in Germany died from heat-related causes.
And these numbers will rise — that's not a prediction, it's the current scientific consensus on climate change.
Why Cities Are Especially Vulnerable
The urban heat island effect makes cities several degrees warmer than their surroundings. Concrete, asphalt, and lack of green space store heat. At night, urban areas barely cool down.
Heat as a Crisis
Physical limits: Above a certain core body temperature (over 40°C), heat stroke threatens — life-threatening if not treated immediately.
Energy spiral: Air conditioning dramatically increases electricity consumption. During a heat wave combined with peak grid load, the blackout risk rises.
Food safety: Without refrigeration, food spoils at 35°C in hours rather than days.
Practical Heat Crisis Preparedness
Make your home heat-resistant:
- Exterior roller blinds (far more effective than interior blinds)
- Night-time cross-ventilation when outside temperature < indoor temperature
- Keep closed and darkened during the day
Secure water supply:
- At least 3–4 liters per person per day during heat (vs. normal 2L)
- Cooling bags and ice packs in the freezer as buffer
Protect vulnerable people:
- Regular contact with elderly, children, chronically ill
- Know cool retreat locations (libraries, shopping centers)
First aid for heat stroke: Recognize symptoms: confusion, hot dry skin, no sweating despite heat, consciousness disturbances
Immediate action: cooler environment, cool the body with wet cloth (neck, armpits, groin), call emergency services
Conclusion
Heat waves aren't an exotic threat — they're the most common climate-related cause of death in Europe. Good crisis preparedness in 2025 includes heat protection, water supplies for hot periods, knowledge of heat stroke first aid, and awareness of vulnerable people in your environment.
