French hospitals face year-round strain as heatwave becomes new normal
A recent heatwave caused a 40% surge in emergency activity and 817 excess deaths, and officials warn that hospitals are now dealing with continuous seasonal stress.
From 27 July to 20 August, 79 French departments experienced a heatwave that matched the longest recorded episode in 1983, resulting in 817 excess deaths and a 40% increase in activity for SAMU and emergency services. Health officials note that the system continues to treat heat as a short-term event, despite it becoming a year-round concern, which strains staffing plans and crisis protocols. Yann Penverne warned that winter pressures are already emerging while the summer heat has not yet been absorbed.
Hospital staffing models still assume a low-activity summer, leading to scheduled vacations, bed closures, and delayed hiring, all of which are now misaligned with reality. Moreover, many hospital buildings were designed for cooler climates, making rooms that cannot stay below 32 °C unsuitable for vulnerable patients. Investment decisions currently prioritize capacity and energy efficiency, leaving thermal resilience largely ignored, forcing a choice between costly retrofits or losing summer capacity.
Why it matters
Continuous heat stress threatens hospital staffing, patient safety, and the capacity of France's health system.
