The increase in the number of hot days per year is associated with a higher incidence among persons aged 65 days and older compared to younger people. This conclusion was made by specialists from the US Centers for Disease Control and Prevention (CDC), who studied the relationship between heat and incidence in the example of counties in Arizona. This is reported in an article published in the journal Morbidity and Mortality Weekly Report.
Researchers studied age-related heat-related morbidity for Maricopa and Yuma counties in Arizona between 2010 and 2020, and analyzed data on seniors’ use of cooling centers, public spaces, between 2018 and 2019. air conditioners to prevent overheating.
The number of hot days in Maricopa and Yuma counties increased on average between 2010 and 2020 (by 1.18 and 1.71 days per year, respectively). Higher hospitalization rates due to heat have been found for adults aged 65 years and older compared to those under 65 years of age. Of the 39 adults aged 65 and older surveyed in Yuma County, 44 percent reported a recent illness. 18 percent reported that the cost of electricity limits their use of an air conditioner.
Previously, researchers from the UK reported that climate change-induced rise in global air temperatures would lead to a 1.5-fold increase in heat-related deaths. There are an estimated 702 heat-related deaths and 67,512 emergency room visits each year in the United States.
