Heart, heart rate variability, and breath rate recorded by Sleep Number app are averaged and are not recorded in real-time for diagnostic purposes. Averages help you track consistency and recognize changes. Keep in mind, average heart rate, and breath rate can be impacted by cardiovascular conditioning, daily stress, alcohol use, age, weight, and overall health. For example, runners tend to have a lower resting heart rate than other people their age. Have a talk with your physician if you are concerned about changes in your biosignals or why your biosignals are different than your sleep partner.
Note: If the heart rate cannot be detected, it will not affect the SleepIQ® Score. The Sleep Number pump should not be relied on as a medical grade heart rate monitor.
How come my Heart Rate doesn't show up?
Sometimes the Sleep Number app is not able to record enough heart rate data throughout the night calculate an average heart rate for an entire sleep session. Possible causes for this are:
You are a Side Sleeper
When you sleep on your side, your profile is smaller, and the smart bed may not be able to pick up your heart rate. Additionally, there are no major veins/arteries along the outside of the arm which may prevent the smart bed from being able to pick up your heart rate.
