多时间尺度气温暴露的健康效应研究进展
Progress in research on the health effects of multi-temporal scale temperature exposure
摘要
Abstract
Driven by global climate changes,the continuous rise in ambient temperatures and the increased frequency of extreme weather events have rendered temperature exposure a critical environmental risk threat-ening human health.Current environmental epidemiological studies evaluating the health effects of tempera-ture employ exposure assessment metrics that span multiple temporal dimensions,including daily mean tem-perature,hourly temperature,long-term average temperature,and temperature variability.While these metrics have substantiated the adverse health impacts of temperature exposure from various perspectives,existing as-sessment frameworks are still in lack of a systematic integration of these exposure indicators.This paper sys-tematically reviewed the health effects and pathophysiological mechanisms associated with metrics such as short-term temperature exposure,long-term exposure,and temperature fluctuations,elucidating that a short-term exposure primarily triggers acute physiological decompensation,whereas a long-term exposure leads to a continuous accumulation of chronic health impairments.Finally,from a cross-temporal perspective,this paper attempted to explore the intrinsic mathematical relationship between long-term climate baselines and short-term temperature variations,thereby providing a methodological reference for establishing a comprehensive climate-health risk assessment framework.关键词
