See your heart rate and sleep stage data overlayed with your glucose data to understand how sleep impacts glucose regulation and how managing your glucose levels can improve your sleep.

To get sleep insights, you'll need to connect a data source.
​
Here's how to set it up:

Under connected apps, select the data source you'd like to use. If you use Oura or Fitbit, you can connect directly. Otherwise, you can connect to Apple Health or Google Fit. You can use most devices that send sleep stages and heart rate to these apps (e.g. Apple Watch).

Note: if you are using Apple Health or Google Fit, you must have a device that stores sleep stage and heart rate data on those platforms.

You are now ready to use sleep insights! By default, sleep stages and heart rate should be enabled. If you have a mix of devices (For example: Apple Health for Exercise, Oura for Sleep), you can make the appropriate adjustments here by toggling on or off the data points you want from each source.

Your sleep event should now come in automatically. Tap the sleep event on your timeline to see your sleep stage data.

When you sleep, your heart rate and glucose utilization decrease because you're not active, and your body shifts to processes that help you recover from the day.
​

Eating late at night, drinking alcohol, or having variable bedtime can cause your heart rate to take a longer time to lower once you fall asleep.
​

This can disrupt your sleep, increase overnight glucose levels, lead to high fasting glucose levels, and cause insulin resistance the following day.
​
Observe the changes in your sleep stages to see how meal timing, composition, and heart rate all impact your sleep.

By understanding the link between glucose, sleep stages, and heart rate, you can adjust your sleep routine and meal timing to recover more effectively.
