In case you missed it: last month, the National Oceanic and Atmospheric Administration and the Centers for Disease Control and Prevention created the nation’s first health-based alert system and heat guidance for clinicians. As part of this effort, the CDC also provides a HeatRisk Dashboard with resources for high-heat days, details on local air quality, and actions to stay safe in these conditions. Finally, the CDC has a site with clinical guidance for heat health, focused initially on treating children with asthma, pregnant women, and people with cardiovascular disease.
