Paris emergency services report around 50% increase in interventions after June heatwave

Paris – 23 July 2026: When stifling heat builds up in apartments and the night brings no relief, phones at Paris emergency services ring more often. Samu de Paris reported an approximately 50% increase in interventions during the June heatwave. This figure shows how extreme temperatures can quickly turn a weather phenomenon into urgent pressure on emergency services and hospitals.

The head of Paris emergency services said that older people are particularly frequently affected. For them, dehydration, overheating and the worsening of existing illnesses can quickly become life-threatening. At the same time, emergency services are also seeing younger patients suffering cardiac arrests. Samu de Paris coordinates medical emergencies in the capital and must decide under time pressure whether to dispatch a team, provide medical advice or arrange transport.

Exceptional heat affected the entire Île-de-France region. Paris and the region’s seven other departments were at times under France’s highest heat alert level from 21 to 28 June. The alert situation had already begun on 17 June. For many people, this meant keeping shutters closed during the day, exhausting nights and concern for relatives living alone or with pre-existing health problems.

The newly published figures from Paris are consistent with regional health data. Santé publique France recorded an increase in emergency admissions and subsequent hospitalizations during the June heatwave. The symptoms monitored mainly included overheating, dehydration and electrolyte imbalance. The number of heat-related treatments by SOS Médecins also rose.

On 22 July, the national health agency also published an initial estimate of excess mortality during the heatwave from 17 June to 2 July. According to this estimate, at least 5,764 more deaths than statistically expected were recorded in the 92 affected departments. This figure includes all causes of death and does not allow direct conclusions to be drawn about individual emergency calls or specific medical developments in Paris.

For rescue teams, the experience shows that heat affects not only older people and those in need of care. People who live alone in high temperatures, have chronic illnesses, perform physical work or underestimate their own limits can all end up in an emergency situation. Samu Paris therefore also indirectly calls on those around them to pay attention: neighbors, families and care staff can recognize warning signs such as confusion, weakness or impaired consciousness early and call for help.
