8 Ways Europe Can Better Protect Older People From Extreme Heat
WHO’s new heat-health guidance offers a blueprint for protecting ageing societies as extreme temperatures become a growing public-health threat.
Extreme heat is no longer an occasional weather emergency in Europe. It is becoming a structural challenge for countries whose populations are also rapidly ageing.
Older adults are among those at increased risk during extreme heat, alongside people with chronic conditions, pregnant women, infants and children. Population ageing and urbanization are themselves among the factors increasing the health burden of extreme temperatures, according to the World Health Organization.
In June 2026, WHO/Europe released the second edition of its Heat–Health Action Plans Guidance, updating recommendations first published in 2008. The new framework is organized around eight core elements designed to help governments, regions and cities prepare for heat before an emergency begins.
For ageing societies, these eight priorities offer a useful roadmap.
1. Make someone responsible
Effective heat planning begins with governance.
WHO recommends clearly defined responsibilities, coordination across sectors and planning that connects health authorities with emergency services, municipalities, social care and other agencies. A heatwave cannot be managed effectively if every institution assumes someone else is responsible.
For older people, that coordination matters because vulnerability may involve much more than healthcare: housing, mobility, social isolation and access to community support can all shape risk.
2. Turn weather warnings into action
Knowing that extreme heat is coming is only useful if a warning triggers a response.
WHO’s framework calls for heat-health warning systems that connect forecasts with predefined public-health measures.
That could mean activating cooling spaces, preparing hospitals and care services, contacting vulnerable residents and communicating practical advice before temperatures peak.
The principle is simple: preparation should begin before people become ill.
3. Know who is most at risk
Not everybody experiences heat in the same way.
WHO identifies older adults among populations at increased risk, but age alone does not determine vulnerability. Chronic illness, disability, medication use, housing conditions and social isolation can compound the danger.
Cities therefore need more than broad demographic statistics. They need systems capable of identifying who may require additional support and how that support can reach them.
For an older person living alone, something as simple as a timely check-in can become part of a heat-health response.
4. Communicate before the emergency
General advice to stay cool is not enough.
WHO places communication among the eight core elements and has included a public-health message bank in its new guidance to help authorities communicate heat risks effectively.
Messages need to be practical, timely and accessible. Older residents and caregivers should know how to recognize heat-related illness, when to seek help, how to keep living spaces cooler and where local support is available.
Communication also needs to reach people who are less digitally connected, rather than assuming an app or social-media alert will reach everyone.
5. Prepare hospitals and care systems
Heatwaves create predictable pressure on health services.
WHO’s framework therefore makes health-system resilience a separate priority.
Hospitals, primary-care services, home-care providers and long-term care facilities need plans for increased demand, adequate staffing and continuity of care during periods of extreme temperature.
This is especially important in ageing societies, where care systems already support growing numbers of people with multiple chronic conditions.
6. Make the places people live cooler
Protection cannot depend entirely on individual behavior.
WHO recommends measures to reduce heat exposure, including longer-term structural interventions. Its 2026 guidance highlights the importance of parks, green spaces, water bodies and measures that protect buildings and communities from heat.
For older residents, the details of the built environment matter enormously: whether a home overheats, whether shade is available on a walking route, whether public water is accessible and whether a cool public space can be reached safely.
Heat resilience is increasingly part of age-friendly design.
7. Count what heat is actually doing
Heat-related harm can be difficult to see in real time.
WHO therefore includes heat-health surveillance as one of its eight core elements.
Tracking illness, hospital admissions and deaths helps authorities understand which populations are being affected, where the greatest risks are and whether interventions are reaching the people who need them.
Without good data, vulnerable groups can remain invisible, and weaknesses in a heat-response system may only become apparent after lives have been lost.
8. Learn after every heatwave
A heat-health plan should not simply sit on a shelf until the next summer.
WHO’s final core element is monitoring, evaluation and learning: assessing whether measures worked, identifying gaps and continually improving plans.
That matters particularly as both Europe’s climate and its demographic profile continue to change. A response designed around yesterday’s temperatures and population may not be adequate for tomorrow.
WHO/Europe’s 2026 guidance makes the broader message clear: well-designed heat-health action plans can significantly reduce preventable illness and deaths.
For Europe’s ageing societies, preparing for heat is increasingly part of preparing for longevity itself. The question is no longer simply how to respond when temperatures rise, but how to design homes, health systems, neighbourhoods and communities in which longer lives can remain safe in a warmer world.
