MONDAY, Feb. 12 (HealthDay News) -- Taking siestas of any frequency or duration is associated with about a one-third reduction in mortality from coronary heart disease, particularly in working men, according to study findings published in the Feb. 12 issue of the Archives of Internal Medicine.
Androniki Naska, Ph.D., of the University of Athens Medical School in Greece, and colleagues examined the association between taking midday naps and mortality from coronary heart disease in 23,681 healthy Greek men and women.
After a mean follow-up of 6.32 years, the researchers found that subjects who took siestas had a lower mortality from heart disease (mortality ratio 0.66). The magnitude of the reduction varied depending on whether the napping was occasional or regular. The association was strongest among working men, according to the study.
"After controlling for potential confounders, siesta in apparently healthy individuals is inversely associated with coronary mortality, and the association was particularly evident among working men," Naska and colleagues conclude.
