HIGH Horizons - Report on predictive heat warning thresholds

This HIGH Horizons report (deliverable 3.3) presents heat health risk thresholds found in literature, threshold related results from WP2 data analysis, methods of determination of the thresholds, heat stress indices, and recommended thresholds at different heat risk levels of the heat health warning system (HHWS) for pregnant and postpartum women, infants and health workers. The selected cut-off thresholds will be implemented in the personalised early warning system (EWS) that the HIGH Horizons consortium is building for pregnant women, infants and health workers, based on ClimApp. The aim of identifying the heat health risk thresholds is to enable the EWS to use these pre-determined trigger levels of heat stress to alert impending heat health risks and provide advice to pregnant and postpartum women, caregivers of infants and health workers to take actions to reduce health risks.
