Wearable EEG Sleep Tracker

Your sleep session reporting provides you with detailed sleep stats to help you uncover your most restorative sleep. Your sleep results will display the number of hours slept, your sleep stages, your heart rate trend, and your sleep position during sleep.

The sleep section also provides post-sleep session journals that allow you to enter notes throughout the night, should you awake, or in the morning to record how you feel upon waking. Are you refreshed or still feeling tired?

These can be leveraged and compared against your sleep stats to help you identify the reasons for a good or a tough night’s sleep. For example, let’s say you found that you had a great sleep and noticed that for that night’s sleep, you mainly slept on your left side and had a long time in deep or REM sleep. You noticed other nights with poorer sleep that you had other sleeping positions. These are clues on how to get your best rest.

Sleep Score

Scored out of 100, your sleep score provides a quick reference to how well you slept and can be used to track your nightly sleep experience sessions. The sleep score is calculated with a lab-grade algorithm that includes time spent in bed awake versus sleeping, your total sleep time, time in deep sleep, and REM stages.

On average, our users tend to have a sleep score of about 75, which can be used as a relative baseline. A score above 75 could indicate a great quality of sleep, but sleep scores are all unique. So it’s best to compare against your own baseline. Once you’ve accumulated enough sleep data, a historical view will be available that will help you begin to understand what your unique baseline sleep score is and track it regularly to help you get the most restorative sleep.

Sleep Stage Overview

Before we explain sleep stage insights, we’d like to provide a little information about sleep stages in general. There are two types of sleep – REM and non-REM. Within non-REM sleep, there are three stages you pass through – awake, light, and deep sleep. Each night we cycle through these four stages several times. Non-REM cycles tend to be longer toward the beginning, while REM is longer toward the end of your sleep.

As you start to fall asleep, you’re between an awake state and light sleep. As you start to drift off, you can awaken easily, and this lasts for only a few minutes. As you move into light sleep, your muscles relax more, your body temperature drops, your brain slows and your eye movements stop.

The next stage of non-REM is deep sleep. Your heart rate and breathing are at their lowest and your muscles are completely relaxed. This is the stage where a lot of restorative processes are at work, such as tissue repair and immune system optimization.

Your REM or Rapid Eye Movement sleep stage is your dream state. This occurs about 90 minutes after you fall asleep. In this stage, your brain is very active. Your heart rate increases, your breathing speeds up, and your eyes, although closed, start moving rapidly. REM sleep is important for memory, mood, and learning. If you sleep eight hours, you’ll enter REM sleep about five times every 90 minutes or so. On average, we spend the majority of time in light sleep, approximately 50%, and just 13 to 23% in deep sleep. And finally, REM accounts for approximately 20 to 25%.
