Europe's 30,000 Heatwave Deaths: Health Risks to Know in Germany

Introduction

Provisional figures have confirmed what many people living through recent European summers already suspected: extreme heat is becoming a serious and deadly public health issue. Across Europe, more than 30,000 excess deaths were recorded during a single summer of back-to-back heatwaves and drought. Scientists have directly linked these events to man-made climate change, and Germany was among the countries affected.

For expats and immigrants living in Germany, this is a wake-up call. Whether you recently arrived from a hot climate and assume you are well-adapted to heat, or you come from a cooler country and find German summers surprisingly intense, the reality is that European heatwaves carry real health risks — and knowing how to protect yourself and those around you could be life-saving.

Why Europe Is So Vulnerable to Heatwaves

Many parts of Europe, including Germany, were built for cold weather rather than extreme heat. Older apartment buildings, which make up a large share of the housing stock in cities like Berlin, Hamburg, and Munich, are well-insulated for winter but can trap heat dangerously in summer. Air conditioning is far less common in German homes than in countries like the United States or southern Europe.

This combination — intense heat outside, poorly ventilated housing, and limited cooling options — creates conditions where indoor temperatures can remain dangerously high even at night, preventing the body from recovering. The result is heat stress, heat exhaustion, and in severe cases, fatal heatstroke.

Climate scientists warn that summers like the one that produced these 30,000 deaths are becoming more frequent, not less. What was once considered an exceptional event is increasingly the norm, and projections suggest temperatures will continue to rise in coming decades.

Who Is Most at Risk?

While anyone can be affected by extreme heat, certain groups face significantly higher risks:

• Elderly people: The body's ability to regulate temperature decreases with age. If you live with or near older relatives or neighbours, check on them regularly during heatwaves.
• Outdoor workers: Construction workers, agricultural workers, delivery drivers, and others who spend long hours outside in summer heat are at elevated risk. Many expats work in these sectors.
• People without access to cooling: Those living in top-floor flats, poorly ventilated rooms, or buildings without shaded outdoor space are more exposed.
• People with existing health conditions: Cardiovascular disease, respiratory conditions, diabetes, and kidney problems all increase heat vulnerability.
• Young children: Their bodies heat up faster and they cannot always communicate distress.

Practical Steps to Stay Safe During Heatwaves in Germany

Germany's national health authorities, including the Robert Koch Institut (RKI), issue guidance during heatwaves. Here are the most practical steps for expats:

Stay hydrated: Drink water consistently throughout the day, even if you do not feel thirsty. Avoid heavy alcohol consumption, which accelerates dehydration.

Keep your home cool: Close blinds and curtains on south- and west-facing windows during the day. Open windows at night when outdoor temperatures drop. If possible, stay in the coolest room in your flat.

Limit outdoor activity: Avoid strenuous exercise or physical work between 11:00 and 17:00 during heat warnings. If your job requires outdoor work, know your rights — German labour law requires employers to take protective measures during extreme heat.

Know the warning system: Germany uses an official heat warning system run by the Deutscher Wetterdienst (DWD), the national weather service. Warnings are issued at two levels: Hitzewarnungen (heat warnings) and strong heat warnings. You can sign up for alerts on the DWD website or via their WarnWetter app.

Use public cooling spaces: Public libraries, museums, shopping centres, and some community centres offer cool environments during heatwaves. Many cities in Germany designate official cooling points (Kühlräume) during extreme heat events.

Your Krankenversicherung and Heat-Related Illness

If you experience heat-related illness in Germany — from severe dehydration to heatstroke — your Krankenversicherung covers emergency medical treatment. If you are enrolled in public health insurance (gesetzliche Krankenversicherung), go to any hospital emergency department. If you have private insurance, carry your insurance card and contact your insurer as soon as possible after receiving treatment.

For non-emergency concerns, contact your GP (Hausarzt) or call the medical helpline 116 117, which operates around the clock.

Frequently Asked Questions

Does Germany have an official heatwave warning system I can follow?

Yes. The Deutscher Wetterdienst (DWD) issues official heat warnings across Germany, broken down by region. Download the free WarnWetter app or visit the DWD website (dwd.de) to receive alerts. During a warning, local authorities may also open designated cooling centres.

Do I have workplace rights during extreme heat in Germany?

Yes. Under German occupational health and safety law (Arbeitsschutzgesetz), employers are required to protect workers from health risks including extreme heat. For outdoor workers, this may include providing shaded rest areas, adjusting working hours, and supplying drinking water. If you believe your employer is not meeting these obligations, you can contact your regional Gewerbeaufsichtsamt (labour inspectorate) for advice.

Conclusion and Next Steps

Europe's 30,000 excess heat deaths are a serious reminder that summer heatwaves are no longer rare events — they are an increasing feature of life on this continent, including in Germany. Taking simple precautions now, understanding your rights as a worker, and knowing how to access medical care through your Krankenversicherung can make a real difference. Download the DWD WarnWetter app, talk to vulnerable people in your life about staying cool, and stay informed as Germany's summers continue to evolve.
