Unfortunately, Naska et al¹ fail to consider overall sleep habits in their work. Short-term sleep deprivation has been shown to have important effects on inflammatory, metabolic, and neuronal pathways including elevations in C-reactive peptide level, insulin resistance, and sympathetic activity, which may promote development of coronary disease.^2-3 In addition, long-term studies suggest that sleep duration is an independent predictor for both incident cardiovascular disease and mortality, exhibiting a U-shaped association, with the minimum risk in those obtaining 7 to 8 hours of sleep.^4-5 Thus, the protective effects of daytime naps may be mediated by increasing total sleep time among those who do not . . .
