Muse Sleep Tracker: The Next Evolution In Sleep Technology

January 14, 2021

We know skimping on sleep isn’t good for us and that just one night of poor sleep can impact everything from our performance at work to our mood and energy. Yet millions of us still don’t seem to log enough quality zzzs each night. In fact, a National Sleep Foundation survey found that at least 40 million Americans suffer from over 70 different sleep disorders (1). While sleep trackers alone are not a silver bullet to solving all of your sleep problems, using an accurate sleep tracker to gain deeper insight into the quality of sleep you are actually getting can be a key first step to helping you feel more energized, refreshed, and focused.

The in-depth overnight tracking data Muse S provides can show you where you can improve and tweak your bedtime routine to start shifting toward deeper, more restorative sleep. With lab-grade precision and brain-powered insights, our new sleep features can help you find your best rest from the comfort of home. 

The New Muse S Sleep Tracker Features

Muse S sleep-tracking is unique in that it features our award-winning EEG technology which gives you an understanding of what’s happening in your brain at night. The lab-grade EEG and PPG sensors can track everything from your sleep position to heart rate, giving you baseline data and personalized insights from which you can set goals and measure progress. 

Here’s an overview of the advanced sleep features we’ve added, others that are coming soon, and how you can use them to start feeling more refreshed and energized now as well as optimize your sleep for the long term. 

1. Sleep Efficiency Score

Monitor & improve your overall sleep efficiency by tracking how long you’re spending in each sleep stage, as well as the total number of interruptions/awakenings in the night. Your score is calculated according to your age and gender demographic group using a few different data points. 

Factors that influence your score include time spent in bed awake vs sleeping (sleep efficiency), total sleep time, and time spent in deep sleep and REM stages.

2. Sleep Stage Tracker & Visualization

Learn how quickly you fall asleep and how deep your slumber is. See the amount of time you spend in each sleep stage (Awake, REM, Light, and Deep) as well as your sleep depth patterns.

3. Sleep Position Tracker

Dive into your sleep positioning. See how often you change sleep positions, how long you were in each, and which is your dominant position.

4. Deep Sleep Insights & Points

Measure the total quantity and intensity of your deep sleep with Deep Sleep Points. In addition to seeing how long you spend in deep sleep, you’ll also gain insight into how deeply your brain rested during this stage based on changes in your slow-wave (delta) activity.

5. Apple HealthKit Integration

Achieve continuous tracking. Let your wearable wrist device recharge while you snooze and the Muse sleep tracker fills in the gaps overnight. Wake up to a 360-degree view of your health and wellness.

Your Post-Session Sleep Tracker Results Explained

Upon waking and ending your session, a Reflection screen will pop up. Here you can simply toggle how refreshed you feel after each sleep session. Do you feel fully refreshed or still a bit groggy? Based on how you feel over time, you can experiment with your sleep routine and make any tweaks needed to help you sleep best.sleep tracking, sleep meditation

Next, you’ll see your post-session stats, starting with your overall sleep score. From sleep position to sleep stages, mind activity to heart rate, your post-session sleep tracker stats give you a complete, personalized picture of your slumber. Since the first step in optimizing your sleep is being aware of your sleep patterns over time, these lab-grade insights can show your sleep quantity and quality so you can find the sleep routine that suits you best. 

Sleep score: Measured out of 100

This is the circled number at the top of your post-session results screen. Your score is calculated with a lab-grade sleep algorithm that includes your age and gender as well as other factors such as time spent in bed awake versus sleeping, your total sleep time, and time spent in deep sleep and REM stages.

Sleep stages: Awake, REM, Light, or Deep

This graph (a hypnogram) shows the different stages of your sleep and how long you were in each. These are calculated using a biosensor algorithm. The vertical access shows four different stages of sleep, each with a different color. When assessing sleep quality, pay attention to the amount of time you spend in each stage and how this changes over time in relation to your habits and lifestyle choices. In the top right corner, you’ll see a score that shows the percentage of time you were in deep sleep.

Sleep position: Right, Left, Back, Front, Sitting Up

This graph shows five different sleep positions and how long you were in each over the course of your snooze. The color on the vertical access indicates whether you were in a Right Side, Left Side, On the Back, On the Front, or a Sitting Up position. Sitting Up refers to any time you weren’t lying down (i.e., sitting up and reading). The score in the top right corner shows the percentage of time you were in your dominant sleep position

Heart rate: BPM

Here you’ll see a graph of your heart rate measured in Beats Per Minute (BPM). Your score in the top right corner shows your average heart rate over the course of your sleep session.

Stillness: Active or Still

How much and to what degree did you move while you slept? On this graph, the darker color indicates higher-intensity movement, while the lighter color indicates lower-intensity. This includes any type of movement—from blinking and teeth grinding to position shifts and leg twitches. The score in the top right shows what percentage of the time you were still while you were sleeping.

Deep Sleep Intensity

Measure the total quantity and intensity of your deep sleep with Deep Sleep Points. In addition to the total time you spent in deep sleep, you’ll also be able to see how deeply your brain rested during deep sleep based on changes in slow-wave (delta) activity. This can only be measured by an EEG device. 

Your Personalized “Me” Screen

It’s you! This screen includes all of your sleep tracker data from all of your sessions. Here you can see your sleep streaks, sleep averages, and what your mood was when you woke up.

You can think of Muse S overnight tracking like a personal sleep assistant. With lab-grade precision, the sleep tracker features give you personalized insights to help you discover a better-focused, more well-rested version of you. From daytime to nighttime use, Muse S can help you understand how to fall asleep, stay asleep, and improve your sleep, so you can feel re-energized and reset each day.

Experience Many Ways to Fall Asleep

When you open your Muse S sleep app, you’ll be greeted by a few different sleep options based on your guidance preferences: Journeys, Soundscapes, and Guidances. Would you like to drift off in a canoe and be lulled to sleep by the simple sound of waves lapping? Choose the Evening Paddle in Soundscapes. Or would you rather have a meditation teacher guide you to relaxation? Choose Soft Body Scan in Guidances. Want a little of both? Choose a Journey. 

With nearly 50 unique sleep experiences across these three categories, you can select the one that fits you best each night.

Journeys

Experience a voice-led meditation by one of our master teachers to help you drift off along with a soundscape of your choice in the background. A simple toggle allows you to adjust the volume of each to find the perfect fit. Journeys include “Gentle River” with Elisha Goldstein, “Exploring the Underwater World” with Palma Michel, and many more!

Guidances

There are 15+ different voice-led guidances by our award-winning teachers to guide you into your best rest, including “Still the Spinning Mind” with Chrissy Carter, “Let Go of Worry” with Faith Hunter and more.

Soundscapes

For the times when you prefer to fall asleep with an immersive soundscape instead of voice guidance, you can choose from 17 different experiences, including “Beach Island”, “Sound Bath”, “Underwater”, and more.

 

Within these new sleep options, you won’t hear any birds. Why? Birds are a reward for active focus which doesn’t apply to sleep. Instead, deep sleep points (coming soon) and a personalized sleep score will let you know how you’re doing and the quality of your sleep. This way, you can simply enjoy drifting off to slumber.
