In a surprising finding, a recent study showed that the most vulnerable population during this extreme heat were people with schizophrenia. (Lee et al., 2023). In a study, epidemiologists from Environmental Health Services at the British Columbia Centre for Disease Control (BCDC) compared the prevalence of chronic diseases in individuals who died during extreme heat in 2021 with the prevalence of individuals who died during the same period in previous years. . The usual suspects—diabetes, heart disease, lung disease, and kidney disease—still appeared. But schizophrenia stood out, with a threefold increased risk of death, the highest of any chronic illness. (Elisavet Chartampila)
