Key Points

• The first heat wave alert of the summer of 2024 began on July 28 and, as of July 29, affects 41 departments under an orange alert across 7 regions. The heat wave is still ongoing.

• The regions of Auvergne-Rhône-Alpes, Centre-Val-de-Loire, Nouvelle-Aquitaine, Pays de la Loire, and Provence-Alpes-Côte d’Azur are all affected by at least one department under an orange heatwave alert and are hosting Olympic events.

• Analysis of emergency care utilization indicates a slight increase in the iCanicule composite health indicator (heatstroke/hyperthermia, dehydration, hyponatremia), though overall numbers remain relatively low.

• The initial health impacts observed underscore that heat poses a health risk, especially since health effects may be delayed by a few days and worsen with continuous exposure over several days. It is important to implement preventive measures to protect the population.
