Heat-health vulnerability in temperate climates: lessons and response options from Ireland.

Heat poses a public and occupational health challenge, receiving limited attention in Ireland. Lack of a co-ordinated effort, places vulnerable populations at risk. Our recommendations, with reference to vulnerable groups and acknowledging the multi-sectoral nature of heat-health and climate change, advocate for the adoption of a "health and climate change in all policies" approach and the development of a public health-focused heat-health action plan.
