Paris: The recent heatwave that swept across Europe has been linked to at least 3,700 excess deaths in France, Belgium and the Netherlands, according to preliminary official data released by health authorities. Officials cautioned that the toll could rise further as additional mortality records are analysed.

The prolonged spell of extreme temperatures, which lasted from around June 20 to June 28, pushed mercury levels well above seasonal averages across much of Western Europe. Scientists have described it as one of the most severe heatwaves ever recorded on the continent, with climate experts saying the intensity of the event was almost certainly amplified by climate change.

The scorching conditions disrupted power generation, strained healthcare services, damaged infrastructure and prompted governments to issue emergency health advisories, particularly for elderly residents and other vulnerable groups.

France records more than 2,000 excess deaths

France reported the highest number of excess deaths among the three countries, with Health Minister Stéphanie Rist confirming that 2,025 additional deaths were recorded during the heatwave.

According to France’s public health authority, the increase was particularly noticeable among people aged above 45 years.

Authorities also reported a sharp rise in deaths occurring at home during the period. Between June 22 and June 28, deaths at home increased by 91 per cent compared with the previous week. Nursing homes and healthcare facilities also witnessed a significant rise in mortality during the same period.

Health officials stressed that the current figures remain provisional and warned that the final death toll is expected to be higher once complete mortality data becomes available.

The French government has continued urging citizens to follow heat safety measures, including staying hydrated, avoiding outdoor activities during peak afternoon hours and checking regularly on elderly family members and neighbours.

Belgium reports unprecedented mortality

Belgium also experienced a significant rise in deaths during the heatwave.

The country’s Health Ministry said around 1,200 excess deaths were recorded between June 18 and June 29, describing the mortality levels as unprecedented during a heatwave.

Of the total deaths, approximately 530 occurred among people aged 85 years and above, highlighting the severe impact of extreme temperatures on older populations.

Authorities also noted that around 180 excess deaths involved individuals younger than 65 years, indicating that the heatwave affected people across multiple age groups rather than only the elderly.

Belgian officials said such a high level of excess mortality during a single heatwave had not previously been recorded in the country.

Netherlands sees rise in deaths among elderly

The Netherlands reported around 480 excess deaths linked to the heatwave.

Dutch authorities said the majority of those who died were aged over 80 years, reinforcing concerns that prolonged exposure to extreme heat remains particularly dangerous for older adults and people with underlying health conditions.

Health officials have continued advising residents to remain indoors during the hottest parts of the day, drink sufficient water and avoid unnecessary physical exertion.

The country also activated various public health measures to protect vulnerable citizens throughout the heatwave.

Scientists link extreme heat to climate change

Climate scientists have said the recent European heatwave was almost certainly intensified by human-induced climate change.

Rising global temperatures have increased both the frequency and severity of extreme weather events, including prolonged periods of exceptionally high temperatures.

Experts note that warmer baseline temperatures make heatwaves more intense, longer-lasting and more dangerous, particularly in urban areas where concrete infrastructure traps heat and limits overnight cooling.

The latest event also placed considerable pressure on electricity networks due to increased demand for cooling, while affecting transport infrastructure and agricultural production in several countries.

Healthcare systems across affected regions also faced increased admissions related to heat exhaustion, dehydration and other heat-related illnesses.

Vulnerable populations remain at greatest risk

Public health authorities across Europe continue to warn that elderly people, infants, outdoor workers and individuals with chronic medical conditions remain the most vulnerable during periods of extreme heat.

Medical experts recommend staying hydrated, wearing light clothing, avoiding direct sunlight during afternoon hours and ensuring adequate ventilation indoors.

Governments have also encouraged local communities to regularly check on older residents living alone, as many heat-related fatalities occur inside homes without immediate medical attention.

With climate models projecting more frequent and intense heatwaves in the coming decades, several European countries are reviewing long-term adaptation strategies aimed at improving urban planning, healthcare preparedness and early warning systems.

Conclusion

The preliminary figure of 3,700 excess deaths across France, Belgium and the Netherlands highlights the growing human cost of extreme heat events in Europe. As authorities continue analysing mortality data, the final toll is expected to increase further. The latest heatwave has renewed calls for stronger climate adaptation measures and improved protection for vulnerable populations as Europe faces increasingly frequent episodes of extreme weather.
