In our continuing efforts to improve SleepWatch for our all of users, we are excited to announce some new features that we hope will improve your insight into sleep. With these new features, you'll get additional feedback on the changes you might be making. Premium users will also be able to see how additional attributes of their sleep compare to SleepWatch users across the globe.
First up is the Average Sleeping Heart Rate Detailed View
You can reach this view by touching the Heart Rate widget in the "Today" view within the iOS app. Here, we aim to help you understand the range of heart rates that can be reached during sleep. We give you an estimate of your Average Sleeping Heart Rate and a visual of where you fall within that typical range. We also provide explanations, tips and references.
While you sleep, your cardiovascular system slows down as the body recuperates and repairs itself to serve you when you are awake. The average rate at which your heart beats during sleep can be an important indicator of your cardiovascular and overall health [link to study]. For most, a slower average sleeping heart rate is better, but you should always check with your doctor to determine what heart rate is expected and ideal for you. Moreover, lack of slowing, or lack of heart-rate dipping at night, has been linked to an increase in all cause mortality [link to study] and has been shown to be a more powerful indicator of health outcome than average sleeping heart rate.
You can click on the "Detailed Graph" bar to see your estimated activity and heart rate over time for your sleep session.
For Premium users, the Average Sleeping Heart Rate value presented here also contributes to your SleepWatch Score such that a lower value can lead to a better score. You will find a graph that shows where you are on a percentile curve in comparison to a group of users who are similar to you in terms of age, sex, and body mass index. A second curve shows how you compare to the larger SleepWatch community.
Next up is the Total Restful Sleep Detailed View
You can reach this view by touching the Total Restful Sleep "donut" widget from within the Today tab of the iOS app.
In this view, we provide an expanded visual, details on the significance of Restful Sleep, and how to interpret your results. Restful Sleep is our estimate of that state of sleep when the body is most still and exhibits the least movement. Health research has found that, generally, deep sleep is associated with the least amount of body movement and individuals who obtain greater amounts of deep sleep were less likely to develop a major cardiovascular risk factor. Depending on your waking habits and nightly rituals, you may affect the total amount and proportion of Restful Sleep you obtain.
We also provide some background, tips, and references in this view, to help you determine which behaviors or conditions may be contributing to more or less restful sleep. For a refresher, take a look at our prior blog on how to get more restful sleep.
For premium users, while Restful Sleep does not currently contribute to your SleepWatch Score, it is an important standalone insight that should add more color to your Score. One of the most common questions that we get for SleepWatch is whether a given percent value for restful vs total sleep is normal. While we cannot say what is normal for any given individual, we provide a graph that shows where you are on a percentile curve in comparison to a group of users who are similar to you in terms of age, sex, and body mass index. A second curve shows how you compare to the larger SleepWatch community. This estimate of where you stand against others could help inform you as to whether you are where you want to be in terms of your Restful Sleep.
It is our honor to serve you, whether you are maintaining good sleep habits or seeking improvement. We know there are many ways to track sleep. At SleepWatch, we value each and every one of our users. We are grateful to you for trusting us with your sleep.
