New research published in Nature Communications reveals that rising global temperatures could increase the prevalence and severity of obstructive sleep apnea (OSA), a common yet underdiagnosed sleep disorder. The study integrates climate models with epidemiological and physiological data, suggesting that heat-induced inflammatory responses and airway resistance contribute to exacerbating OSA. This environmental factor adds complexity to traditional risk determinants such as obesity and age, indicating a growing public health challenge amid climate change.
