The impact of high temperatures and heatwaves on health outcomes among working-age adults (15–64 years): a systematic review and meta-analysis

High temperatures and heatwaves significantly increase morbidity and mortality among working-age adults (15-64 years), particularly due to occupational and environmental factors. Greater risks were observed in humid subtropical and Mediterranean climates, with notable increases in heat-related illnesses and genitourinary disorders. These findings highlight the need for broader heat vulnerability assessments and inclusive prevention strategies beyond workplace settings.
