摘要

IN A 2013 SURVEY conducted by the Arlington, VA-based National Sleep Foundation, 56 percent of respondents reported sleeping more on weekends or non-workdays than on workdays. Among all respondents, U.S. adults averaged 7 hours and 22 minutes of sleep on those days versus an average of about six-and-a-half hours on workdays.
