Impact of Extreme Ambient Temperatures on Psychiatric Hospital Admissions in an Arid Urban Environment in Iran: A Time-Series Dataset

This study explores the relationship between extreme temperature events and psychiatric hospital admissions in the hot-arid region of central Iran, filling a critical gap in climate and mental health research. Leveraging time-series data from 7,639 cases at Yazd's sole psychiatric hospital from 2014 to 2020, advanced statistical analyses assessed the impact of daily minimum temperatures on admissions within a one-week lag. The findings indicate that extreme heat significantly increases the likelihood of psychiatric admissions, particularly for mood disorders, with the most substantial effects occurring immediately or shortly after exposure. Vulnerability to extreme temperatures varies by demographic factors, with men, married individuals, and younger adults exhibiting heightened sensitivity to heat, while women and older adults show delayed responses to extreme cold. These results underscore the pressing need for targeted mental health interventions that consider the effects of climatic extremes, particularly for vulnerable populations, and provide essential insights for climate-responsive healthcare planning in arid regions.本研究聚焦伊朗中部炎热干旱地区，探讨极端气温事件与精神科住院人次之间的关联，填补了气候与精神健康研究领域的关键空白。本研究依托亚兹德市唯一一家精神科医院2014至2020年间的7639例病例时序数据，通过高级统计分析，评估了日最低气温在一周滞后期内对住院人次的影响。研究结果显示，极端高温会显著提升精神科住院风险，尤以心境障碍群体为甚，且其影响多在暴露后即刻或短期内显现。不同人口学特征群体对极端气温的易感性存在差异：男性、已婚人群与青年群体对高温的敏感性更高，而女性与老年群体则对极端低温呈现出延迟响应。本研究结果凸显了针对气候极端事件影响制定针对性精神健康干预措施的迫切性，尤其需重点关注易感人群；同时也为干旱地区适配气候的医疗保健规划提供了重要参考依据。
