A recent cross-sectional study published in the journal Sleep evaluated 245 high school students in a community setting.  For one week during the school year, students provided fasting blood glucose samples, a sleep diary/log, and wore a wrist actigraph, which measured the duration of inactivity.  An average of 7.4 hours of sleep was reported in the sleep logs, while an average of 6.4 hours was based on the actigraph, with weekends significantly higher than the weekdays. After adjustment for other factors, higher insulin resistance was seen in students who had a shorter sleep duration.  How much sleep do you get? How much sleep do you recommend to your patients?
