WHO Warns Europe Could Face More Deadly Heatwave Weeks as New Extreme Temperatures Loom

The World Health Organization (WHO) has warned that Europe may experience “more deadly weeks” as another powerful heatwave builds over the Atlantic. Health officials say the next wave of extreme temperatures could place millions of people at risk, particularly older adults, young children, people with chronic illnesses, and outdoor workers.

According to the WHO Regional Office for Europe, temperatures in parts of Portugal and southern Spain could reach 43°C (109°F), while France, Belgium, the Netherlands, and neighboring countries are expected to experience another surge in dangerous heat.

Why the WHO Is Concerned

Heatwaves are more than uncomfortable weather events—they are a serious public health emergency. Prolonged exposure to extreme heat can lead to dehydration, heat exhaustion, heatstroke, and can worsen heart, lung, and kidney conditions.

WHO Regional Director Dr. Hans Henri P. Kluge said that countries with well-prepared heat-health action plans were able to respond more quickly and better protect their populations during the recent heatwave. However, the organization also noted that fewer than half of the countries in the WHO European Region currently have national heat-health action plans in place, leaving many communities vulnerable.

Countries Prepare for Another Heatwave

Following the recent spell of record-breaking temperatures, governments across Europe are increasing emergency measures. Authorities are expanding cooling centers, issuing health alerts, and encouraging residents to avoid outdoor activities during the hottest hours of the day.

Some cities have also improved coordination between health services, emergency responders, and weather agencies to reduce the impact of extreme heat. Despite these efforts, experts warn that preparation remains uneven across the region.

Health Tips to Stay Safe During Extreme Heat

If you live in or travel to an area affected by high temperatures, consider these precautions:

• Drink plenty of water, even if you don’t feel thirsty.
• Stay indoors during the hottest part of the day.
• Wear lightweight, light-colored clothing.
• Use fans or air conditioning whenever possible.
• Check on elderly family members and neighbors.
• Never leave children or pets inside parked vehicles.
• Seek medical attention immediately if someone shows signs of heatstroke, such as confusion, fainting, or a very high body temperature.

Climate and Public Health

Scientists continue to warn that climate change is increasing the frequency and intensity of extreme heat events across Europe. Public health experts say stronger preparedness, improved urban planning, and better public awareness will be essential to reducing future heat-related illnesses and deaths.

Final Thoughts

The WHO’s latest warning serves as an important reminder that extreme heat is a growing health challenge. While governments continue to strengthen emergency response systems, individuals also have a vital role to play by staying informed, following official guidance, and taking simple precautions to protect themselves and their families.

As Europe prepares for another period of intense heat, awareness and early action remain the best defenses against heat-related health risks.
