Bedtime Consistency and T1D: Why Timing Beats Total Hours for Blood Sugar Control

SHOW NOTES:You've been told to get eight hours. Here's what the research actually found.A 2023 study of 76 adults with type 1 diabetes tracked both CGM and sleep data for one week. The finding: sleep duration alone was not independently associated with time in range. What was? Bedtime consistency. Every extra hour of variability in bedtime was associated with roughly 10% less time in range. Your CGM noticed. It was taking notes.This episode reframes the sleep conversation for T1D: it's not just about how much you sleep. It's about when. Your body doesn't know it's Saturday. Your cortisol doesn't know it's Saturday. Only your social calendar knows it's Saturday -- and your social calendar is not in charge of your A1C.We're in Week 3 of the While You Were Sleeping Challenge.In this episode:The 2023 T1D sleep study and what it actually measuredWhy six people who each got 7 hours got six different resultsWhat bedtime consistency means practically -- and why it matters more than total hoursWhy weekend sleep timing is where this breaks down for most peopleThe 60-minute window and why it worksThis Week's Challenge: Try to go to bed within a 60-minute window of the same time, three nights this week.
