Arecent study found that the death rate for people who sleep 6 to 7 hours per night is lower than the death rate for people who sleep 8 or more hours. the 1.1 million observations used for this study came from a random survey of americans aged 30 to 102. each survey respondent was tracked for 4 years. the death rate for people sleeping 7 hours was calculated as the ratio of the number of deaths over the span of the study among people sleeping 7 hours to the total number of survey respondents who slept 7 hours. this calculation was then repeated for people sleeping 6 hours, and so on. based on this summary, would you recommend that americans who sleep 9 hours per night consider reducing their sleep to 6 or 7 hours if they want to prolong their lives
