Abstract
Extremes in both cold and heat are pushing the human body’s ability to regulate temperature, leading to dehydration, heat stress, cardiovascular strain, and reduced immune function, among other effects, making individuals more susceptible to various health conditions. Vulnerable individuals are the most at risk, yet the extent to which racial disparities might exist and augment the vulnerability of minorities remains unclear. In the absence of such knowledge, health inequity and environmental injustice is likely to persist. This work examined racial disparities in temperature-related deaths in the United States and revealed higher mortality among minorities, particularly in relation to extreme heat. The findings can help decision makers target interventions and direct resources for coping with extreme temperatures to the most vulnerable communities, as well as reduce inequities in access to healthcare. Ultimately there is a need to work towards ensuring that all populations have equal protection from the health impacts of climate change.
