The National Sleep Foundation released its 2010 Sleep and Ethnicity Poll results today, uncovering unexpected findings that will forever stand in the way of some much beloved wives tales vis-a-vie sex and good sleep.
The poll, conducted by telephone with over a thousand participants, seems to be completely legit, with a nice PDF brochure of its "Summary of Findings," which contains lots of graphs and charts.
Word of warning: please consult that brochure yourself, because I stand behind none of these conclusions.
One of the stated goals of this research effort was: "To investigate attitudes and behaviors about the relationship between sleep and health across different ethnic groups." Last on the Foundations list, first on mine.
