Understanding the epidemiology and clinical features of heat-related illnesses in children is crucial for guiding targeted preventive measures and management strategies. This descriptive study aims to investigate the characteristics of pediatric patients with heat-related illness who were transferred to emergency departments in Japan.Methods: This study was a secondary analysis of the Heatstroke Study, led by the Heatstroke and Hypothermia Surveillance Committee of the Japanese Association for Acute Medicine. This study included pediatric patients (&lt;18 years) with heat-related illness transferred to emergency departments in the summer from 2017 to 2021. We summarized the circumstances of onset, clinical characteristics, and outcomes.Results: Of the 3,154 registered patients, 146 children were included. Of them, 60% were male, with a median age of 15 years (interquartile range, 13\u201316 years). The most cases occurred in August (47%), and most (80%) were associated with sports activities and with outdoor settings (70%). Cases with a body temperature above 40 \u00b0C were rare (3%). Most cases were admitted to hospitals (75% to the general ward and 16% to the intensive care unit), and patients admitted to intensive care unit had altered consciousness with increased serum creatinine. There were two cases of mortality, both of which were out-of-hospital cardiac arrest.Conclusion: Most pediatric cases with heat-related illness were middle or high school students, occurred in August, and were related to outdoor sports activity. Patients admitted to hospitals suffered altered consciousness, dehydration, and acute kidney injury.<\/jats:p>","DOI":"10.15441\/ceem.24.343","type":"journal-article","created":{"date-parts":[[2025,4,30]],"date-time":"2025-04-30T04:55:17Z","timestamp":1745988917000},"page":"369-379","update-policy":"https:\/\/doi.org\/10.15441\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Characteristics
