Science Daily — Among Greek adults, taking regular midday naps is associated with reduced risk of death from heart disease over a six-year period, especially among working men, according to a report in the February 12 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Some evidence suggests that in countries where siestas are common, rates of death from heart disease tend to be lower. However, the few studies that have assessed the potential relationship have not controlled for other factors that may influence heart disease risk, such as physical activity and age, according to background information in the article.
Androniki Naska, Ph.D., University of Athens Medical School, Greece, and colleagues studied 23,681 Greek men and women ages 20 to 86 who did not have a history of heart disease or any other severe condition when they enrolled in the study between 1994 and 1999. At the beginning of the study, participants were asked if they took midday naps, and if so, how often and for how long at a time. They also reported their level of physical activity and dietary habits over the previous year.
