Heatwave prevention measures according to the Regional Health Agency (ARS)
Faced with the increasing frequency of heat waves, particularly in the Châteaubriant region of Loire-Atlantique, the recommendations of the Regional Health Agency (ARS) are essential to protect the population. In 2025, the ARS emphasizes systematic prevention and vigilance measures, especially for vulnerable individuals, to limit the health risks associated with these extreme weather events. Staying informed, adopting the right practices, and benefiting from local support will contribute to a safer and more peaceful summer in the Châteaubriant-Derval inter-municipal community and beyond.
Essential measures to prepare for heat waves in the Châteaubriant inter-municipal community:
Preparing in advance is the first essential step in the face of the heat waves that affect the Châteaubriant region and Loire-Atlantique. According to the ARS, identifying vulnerable individuals – the elderly, disabled, or those with underlying health conditions – is vital to organizing effective assistance as soon as the first signs of heat-related hardship appear. Local town halls provide registration lists for isolated individuals, enabling rapid intervention by volunteers during heat waves.
Those affected are advised, in consultation with their families and friends, to prepare a heat-protection kit: a misting spray, a fan, and a list of nearby air-conditioned locations, such as shops, cinemas, or libraries, where they can cool off. This local organization is particularly important in the Pays de la Mée region, where access to cool public spaces can be a crucial advantage.
Healthcare professionals, particularly general practitioners, play a key role in anticipating necessary adjustments to medical treatments during periods of intense heat. Every year, the Regional Health Agency (ARS) reminds patients of the importance of consulting their doctor before the summer season to adjust dosages or consider additional measures. This vigilance is essential to prevent heat-related complications, which can occur in patients taking multiple medications. Finally, public awareness campaigns encourage the use of reliable information channels such as Public Health France or the official website info.gouv.fr, as well as the regional resources offered by the Auvergne and Loire ARS.

without waiting for the feeling of thirst is essential. Indeed, high temperatures accelerate dehydration, making vigilance mandatory.
Staying cool remains essential. It is advisable to wet your body several times a day using a spray bottle, a damp washcloth, or by taking cool showers to lower your body temperature and prevent heatstroke. The appropriate use of a fan or air conditionerfor individual use is recommended, although the Regional Health Agency (ARS) advises against their use in communal spaces to avoid harmful side effects.
Homes should be kept cool: closing shutters and windows during the day limits the heat accumulated inside, while nighttime ventilation takes advantage of the lower temperatures. These simple actions are very effective, especially in the typical houses and apartments of the Loire-Atlantique region. To limit exposure to heat waves, it is advisable to avoid going out during the hottest hours, wear a hat and light clothing, and favor air-conditioned places such as libraries or nearby shopping centers, thus strengthening community resilience. To illustrate the importance of these measures, here are the main guidelines to follow during a heatwave: Drink water regularly,
even if you’re not thirsty, to combat dehydration.
Wet your body and use a fan several times a day with a spray bottle, showers, or a damp cloth.
Cool your home by closing shutters and windows during the day and ventilating at night.
- Avoid alcohol and sugary drinks, which further dehydrate you.
- Limit physical activity to cooler hours to reduce fatigue and discomfort. Check on vulnerable people,
- who are isolated or elderly, for moral and physical support. Never leave anyone in a closed vehicle,
- especially children and animals. Call 15 (the French emergency number) if you feel unwell or experience signs of severe heatstroke.
- Behavior Expected Effect
- Regular hydration Prevents dehydration and heatstroke
- Wetting the body Lowers body temperature quickly
- Avoid physical exertion Reduces the risk of sunstroke and exhaustion
| Stay in a cool place | Maintains the body at an optimal temperature |

| Heat waves also have a significant impact on the health of workers exposed to extreme temperatures. In the Châteaubriant region and more broadly in Loire-Atlantique, professionals in the construction, agriculture, and public works sectors are particularly affected. The ARS (Regional Health Agency) and the Ministry of Labor are urging employers to adapt work organization to reduce risks. | |
| These measures include adjusting work schedules to avoid exposure during the hottest hours, providing sufficient quantities of fresh drinking water, and allowing for frequent breaks in shaded or air-conditioned areas. Furthermore, certain strenuous physical tasks should be limited or postponed during heat waves. | Implementing these practices has demonstrated a significant reduction in heat-related accidents and illnesses in exposed professions. The Regional Health Agency (ARS) emphasizes the importance of integrating these measures into each company’s single risk assessment document, as recommended in the official guide on heat wave risk prevention. |
These efforts are part of a regional initiative to protect employee health and anticipate the risks associated with climate change. The focus on the Châteaubriant-Derval Community of Communes area should raise awareness among employers and employees regarding the need for proactive and tailored prevention.

| Local initiatives in Châteaubriant and the Pays de la Mée region to strengthen prevention | The fight against the effects of heat waves is also demonstrated through concrete actions within the Châteaubriant-Derval Community of Communes. Partnerships between the Regional Health Agency (ARS), local authorities, and associations make it possible to organize awareness campaigns adapted to the specific characteristics of the region. | Measures such as the summer opening of air-conditioned public spaces – libraries, municipal halls, or senior centers – facilitate residents’ access to cool spaces. Furthermore, the local solidarity network mobilizes volunteers and caregivers to support isolated individuals, with active monitoring during heatwave alerts. These actions are based on national guidelines relayed, among other places, on the ARS Hauts-de-France website. |
| Adaptable to the local level. | The involvement of local elected officials is also essential. For example, as part of increased monitoring, the Châteaubriant town hall maintains an up-to-date list of vulnerable populations and regularly disseminates alerts through local communication channels to encourage adherence to best practices. | |

- Actions to take to protect children and vulnerable people during heat waves
- Children, the elderly or dependent individuals, as well as pregnant women, are among the populations most exposed to the risks associated with extreme heat in the Pays de la Mée region. To protect these groups, the Regional Health Agency (ARS) recommends specific measures and increased vigilance.
- It is particularly important to ensure regular and adequate hydration, paying particular attention to the frequency and quantity of water consumed, as children, like the elderly, feel thirst less. Their bodies being more fragile, regular wetting (with a damp cloth or a spray bottle) is also essential to limit overheating.
It is advisable to avoid prolonged exposure to the sun, especially during the hottest part of the day. In this context, access to safe, air-conditioned spaces (community halls, libraries, or cinemas) provides essential relief from the heat. Lightweight, light-colored, and covering clothing, as well as wearing a hat, offer effective protection. Parents and caregivers are encouraged to check in regularly, especially on those who are isolated or live alone. In case of warning signs – persistent headaches, nausea, significant fatigue, altered mental status – immediately call 15 (the French emergency number)
for prompt medical assistance.
Keep children and vulnerable individuals well-hydrated.
Regularly wet the body with showers or spray bottles. Limit outings to the cooler hours and choose air-conditioned spaces. Dress people in lightweight clothing and appropriate headwear.
Check in regularly and monitor for symptoms. Never leave children or vulnerable individuals in a closed vehicle.
