With global warming, heat waves are becoming more frequent and intense, particularly in northern latitudes, where the pace of warming is faster. Due to its northern location, Swedish society has been built primarily to manage a cold climate, and is less prepared to manage heat, which the 2018 heat wave demonstrated. While young children are recognized as vulnerable to heat, and are reliant on preschool care, few studies have examined how the young and vulnerable people are cared for during heat waves in the institutional preschool setting. This exploratory study demonstrates how children in preschool environments are vulnerable to heat, in order to identify management needs by assessing experienced impacts and responses to the 2018 heat wave in Sweden. Empirically, the study builds on a survey completed by 33 unit heads responsible for 77 preschools in the focused municipality, and qualitative interviews with five educators and five parents, as well as temperature measurements in three selected preschools. This study shows that: (i) children and educators are exposed to both high indoor and outdoor temperatures in the preschools; (ii) both children and educators were affected by the heat wave in the preschools, and their sensitivity is deeply intertwined due to their dependency relationship, rendering a form of double sensitivity to heat; and (iii) the preschool heads and educators were unprepared to sufficiently cope with the heat wave, and organizational strategies for managing heat were lacking, indicating weak adaptive capacity. The significant exposure to heat in preschool environments, the dual sensitivity of children and preschool educators, and the low organizational readiness resulting in uncoordinated responses to reduce heat stress suggest a pronounced vulnerability to heat waves in preschools.

随着全球变暖，热浪变得越来越频繁和强烈，特别是在北方地区，那里的变暖速度更快。由于其北部位置，瑞典社会的建立主要是为了管理寒冷的气候，而对热量管理的准备却较少，2018年的热浪就表明了这一点。尽管幼儿被认为容易受热，并且依赖学龄前儿童照料，但很少有研究研究了在机构学龄前环境中热浪期间如何照顾年轻人和弱势群体。这项探索性研究证明了学龄前儿童在高温下如何易受伤害，以便通过评估瑞典2018年热浪带来的影响和应对措施来确定管理需求。根据经验，该研究基于33个单位负责人完成的调查，这些负责人负责该重点城市的77个学前班，并对5位教育者和5位父母进行了定性访谈，并对3个选定的学前班进行了温度测量。这项研究表明：（i）在学龄前儿童和教育者都暴露于室内和室外高温下；（ii）在学前班中，儿童和教育者都受到热浪的影响，由于他们之间的依赖关系，他们的敏感性深深地交织在一起，从而形成了对热的双重敏感性；（iii）学前班主任和教育者没有做好充分应对热浪的准备，并且缺乏管理热量的组织策略，表明适应能力较弱。在学前环境中大量暴露于热中，
