Heat Health Risks in Germany: One in Three People Now Affected

Introduction

Germany is not a country typically associated with extreme heat, but that picture is changing fast. A new nationwide survey has found that one in three people living in Germany now report experiencing heat-related health problems — including exhaustion, disrupted sleep, and circulatory issues. For expats, particularly those from countries with hotter climates who might underestimate the specific risks of German urban heat, or those working outdoors or in warehouses without cooling, this is a practical health and workplace story worth taking seriously. Here is what the survey found, and what you can do to protect yourself.

What the Survey Found

The survey, conducted across Germany, found that heat is no longer a fringe concern but a mainstream public health issue. The most commonly reported problems were:

• Exhaustion and fatigue during hot periods
• Sleep disruption, particularly in urban areas where nights stay warm
• Circulatory problems, including dizziness, low blood pressure episodes, and in more severe cases, heat stroke symptoms

The findings reflect a broader trend: Germany has experienced a succession of record-breaking heat events in recent years, and urban areas — where the "heat island" effect raises temperatures further — are particularly affected. Cities like Berlin, Frankfurt, and Munich have all recorded temperatures above 38°C in recent summers.

People most at risk include the elderly, young children, outdoor workers, people with cardiovascular or respiratory conditions, and those living in poorly ventilated housing — a category that includes many expats renting older apartments without air conditioning.

What This Means for Workers in Germany

For expats working in Germany, particularly in outdoor roles, construction, delivery, or warehouse logistics, German labour law does contain some protections during extreme heat, though they are less prescriptive than in some other countries.

Under the German Arbeitsstättenverordnung (Workplace Regulation), employers are obligated to maintain a reasonable working temperature. For office environments, the guideline temperature is a maximum of 26°C, with recommendations to take action above that. For outdoor or industrial workers, the rules are more flexible but employers are still required to conduct risk assessments and provide protective measures during heatwaves — including adequate water, shade, and rest periods.

Importantly, Germany does not have a legally mandated maximum outdoor working temperature, unlike some EU member states. This means that in practice, worker protection during heat depends significantly on the employer's commitment to health and safety standards and whether a works council (Betriebsrat) is present to advocate for employees.

If you feel that your employer is not taking adequate heat safety measures, you can contact the relevant Gewerbeaufsichtsamt (Labour Inspectorate) in your federal state.

Practical Tips for Staying Safe

Regardless of where you work, there are straightforward steps you can take during hot periods in Germany:

• Hydrate actively: Drink water regularly throughout the day, even if you do not feel thirsty. Germany's tap water is safe and high quality everywhere.
• Adapt your routine: Do physical activity and outdoor errands in the early morning or evening. Avoid the 12–16:00 window on hot days.
• Protect your sleep: Use blackout curtains and keep windows closed during the day to trap cool air, opening them at night when temperatures drop.
• Know the warning signs: Dizziness, nausea, rapid heartbeat, or confusion during heat are emergency signals. Call 112 if you or someone near you shows signs of heat stroke.
• Check on neighbours: Isolation in hot weather is dangerous, especially for elderly people. If you live in an apartment building, a quick check on neighbours is worthwhile.

Frequently Asked Questions

Does Germany have official heat warning systems I should follow?

Yes. The Deutscher Wetterdienst (DWD), Germany's national meteorological service, issues official heat warnings (Hitzewarnung) when temperatures are forecast to exceed thresholds that pose health risks. These warnings are publicly available on the DWD website and app, and are broadcast through media channels. Local authorities and health departments also issue advisories. It is worth downloading the DWD app or checking their website during summer months.

Am I entitled to time off or reduced hours if it gets too hot at work?

Not automatically, no. German law does not give employees an automatic right to leave early or work reduced hours due to heat unless a collective agreement (Tarifvertrag) or individual employment contract specifies otherwise. However, your employer does have a duty of care. If indoor workplace temperatures exceed 30°C, employers must begin taking protective measures; above 35°C, the workspace is considered unsuitable without additional cooling measures. Document any concerns and raise them with your employer or works council first, then with the Gewerbeaufsichtsamt if needed.

Conclusion and Next Steps

Heat is a growing public health challenge in Germany, and one in three residents already feeling the effects is a significant figure. For expats — especially those in physically demanding jobs, older housing, or who have moved from cooler climates — being aware of the risks and knowing your rights is the best preparation. Follow DWD warnings, know your employer's obligations, and do not hesitate to seek medical help if you experience serious symptoms. Your Krankenversicherung covers heat-related medical treatment just like any other health issue.
