How to Use Your Overnight CGM Data to Improve Sleep and Blood Sugar

SHOW NOTES:

You've been sleeping next to one of the most detailed health monitoring devices that exists. Every single night. For however many years you've had your CGM. It has been logging everything -- every rise, every drop, every 3am event, every overnight pattern. It has been very patient about all of this.

Most T1D people use their CGM reactively at night. The alarm fires, you check, you respond or silence, you go back to sleep. What almost no one does is look at the full overnight graph proactively -- not to respond to a single moment, but to read the shape of the whole night. Your CGM shows you the dawn phenomenon, the post-exercise glucose drop, the cortisol spike, the active insulin tail. It has been a map this whole time. We've been treating it like a fire alarm.

This is Week 7 of the While You Were Sleeping Challenge. This is the episode that changes how you use the device you already wear.

In this episode:

The difference between reactive and proactive overnight CGM use
How to read the shape of an overnight graph -- not just the morning number
What the dawn phenomenon, exercise drops, and cortisol spikes look like in your data
Why your CGM graph is a map, not a report card
How one minute of overnight data review can improve the next night

This Week's Challenge: Tonight, look at last night's full overnight CGM graph. The whole shape. Not to judge it. Not to fix it. Just to see what was there.
