Rising Temperatures Set to Triple Heat-Related Cardiovascular Deaths in the US

A study supported by the National Institutes of Health predicts that cardiovascular-related deaths due to extreme heat will increase in the United States between 2036 and 2065. Older adults and Black adults are expected to be disproportionately affected, as they often have underlying health conditions and face socioeconomic barriers that can influence their health. The study estimates that each summer, about 71 to 80 days will feel 90 degrees or hotter, leading to a projected increase in annual heat-related cardiovascular deaths from 1,651 to 4,320 for the general population. The number of deaths could more than triple if greenhouse gas emissions rise significantly. The researchers emphasize the importance of taking extra steps to avoid extreme temperatures, especially for those with underlying health risks.
