This study will determine whether extreme ambient temperatures increase the incidence and severity of occupational injuries in Israel, and we request Helsinki Committee approval to conduct the analysis using de-identified National Insurance and historical meteorological data, with a waiver of informed consent. The project will link the date, time, and geographic location of recognized occupational accidents with corresponding historical temperature and humidity measurements. The study is retrospective, observational, and involves no direct contact with participants, no intervention, and no alteration of medical care or benefit eligibility.
