The new dashboard underscores the disproportionate impact of extreme heat on vulnerable populations, including older adults, Black residents, and those living in areas with limited access to cooling resources. Heat-related illnesses often exacerbate preexisting conditions such as heart, respiratory, and kidney diseases, leading to increased emergency room visits. The San Fernando and San Gabriel valleys are particularly at risk due to a combination of high temperatures and socioeconomic factors. Public health experts emphasize that heat-related illnesses are preventable with adequate resources and awareness.
