In response to a severe heat wave that struck France in June, the government has enlisted postal workers to conduct welfare checks on elderly and isolated residents as part of a broader effort to prevent heat-related fatalities. The initiative aims to leverage the unique position of mail carriers who regularly visit homes across communities.

In Aix-les-Bains, a lakeside town in southeastern France, postal worker Harmony Simon has been visiting vulnerable individuals during her delivery rounds to ensure their well-being amid soaring temperatures. During one visit, she checked on Martine Combe, a 68-year-old retiree with diabetes and asthma, who was struggling with the heat in her apartment lacking air conditioning. Simon advised Combe on practical measures to reduce indoor temperatures, such as using reflective survival blankets on windows — a simple but effective method that can lower room temperatures by several degrees.

The program was launched following a deadly heat wave in June that resulted in nearly 6,000 fatalities nationwide, according to Santé Publique France, the country’s public health agency. Two-thirds of the deaths occurred among those aged 75 and older, many of whom lived alone. A notable increase in mortality was reported among people remaining at home, highlighting the risks faced by vulnerable individuals isolated during extreme weather events.

Prime Minister Sébastien Lecornu endorsed the measure, emphasizing that postal workers often represent one of the few regular points of contact for elderly or isolated citizens. In a letter to mayors, he outlined the government’s strategy to use the postal service’s network of approximately 65,000 employees to supplement local authorities' efforts in monitoring at-risk populations during heat waves. This approach also addresses limitations in current registries of vulnerable residents, which can be incomplete or out of date.

While French cities maintain lists of residents who have opted into welfare checks during heat emergencies, municipal officials acknowledge challenges in identifying all individuals in need. The postal service’s extensive presence in communities presents an opportunity to reach those who may not be registered or are otherwise difficult to contact.

The frequent and intense heat waves affecting France parallel trends across Europe, the continent most rapidly warming and characterized by an aging population. As extreme temperatures become more common, health and social services continue to adapt to mitigate risks, with programs like the postal welfare checks reflecting an innovative use of existing infrastructure to safeguard vulnerable citizens.
