When temperatures rise, the risks are not shared equally. Pregnant and postpartum women, newborns and children are particularly vulnerable to heat exposure. Yet gaps in monitoring can leave its effects on their health insufficiently understood and their needs overlooked in climate and health responses.

Priority indicators to monitor the impact of heat exposure on maternal, newborn and child health provides a practical starting point for closing these gaps. It helps countries bring health and heat exposure data together to identify warning signs, guide further investigation and inform preparedness and response.
