The heat wave, which lasted from around June 20 to June 28, is being described by experts as one of the most intense on record in parts of Europe, with widespread exposure to prolonged extreme temperatures and unusually warm nights.
Public health experts say most deaths during extreme heat are not caused by heat alone in isolation, but by a combination of physiological stress and pre-existing medical conditions. When the body is exposed to prolonged high temperatures, it struggles to regulate internal heat through sweating and circulation. This can lead to dehydration, heat exhaustion, and in severe cases heatstroke, where core body temperature rises to dangerous levels.
Heat also places significant strain on the cardiovascular system, forcing the heart to work harder to cool the body. This can trigger or worsen heart attacks, strokes, and respiratory failure, particularly among older adults and people with chronic illnesses such as heart disease or diabetes. Medication effects and reduced ability to stay hydrated can further increase risk.
France reported 2,025 excess deaths, a 29.1% increase above normal levels. Authorities said deaths rose sharply in private homes, by more than 90% in the week of peak heat, while care homes and healthcare facilities also saw increases. Officials warned that final figures are likely to be higher.
Belgium recorded 1,222 additional deaths, describing the impact as 'unprecedented,' while the Netherlands reported around 480 excess deaths, concentrated in hotter southern and eastern regions.
Across Europe, more than two-thirds of the population experienced temperatures above 35°C, with record highs and unusually warm nights limiting recovery time. Experts say such 'night heat' is especially dangerous because it prevents the body from cooling down after daytime exposure.
The event has renewed concerns about Europe's preparedness for extreme heat, particularly as climate change increases both the frequency and severity of heat waves.
