Effect of sleep loss on beta-endorphin activity, epinephrine levels, and ventilatory responsiveness.


Sleep loss impairs ventilatory responsiveness to hypercapnia and hypoxia, and also interferes with performance on spirometry. To test the hypothesis that the decline in hypercapnic drive due to sleep loss is mediated by endorphin production, we measured loaded and unloaded CO2 response after injection of placebo and naloxone in 11 normal subjects who were… (More)
