Monitoring Sleep and Glucose Among University Students

In the baseline sleep condition, participants are instructed not to restrict their sleep on the night before completing an oral glucose tolerance test (OGTT). Participants are prescribed sleep-wake timings based on their preferred and averaged sleep durations measured over 2 weeks using a wearable sleep tracker. Sleep timings and durations on the 3 nights before the OGTT are verified using a sleep diary and sleep tracker.

In the sleep restriction condition, participants are prescribed sleep timings to restrict their sleep by 1 to 2 hours on the night before completing an oral glucose tolerance test (OGTT). Sleep timings and durations on the 3 nights before the OGTT are verified using a sleep diary and sleep tracker.
