While sleep summaries display your vitals from each night with Oxa, sleep trends answer: “how is my sleep changing over time?” After 3 nights, Oxa displays trends, which can be filtered by various windows of time.
This article explains:

What are Sleep Trends?
Oxa’s Sleep Trends compile, analyze, and display the assessment of your sleeping state, including sleep health, bedtime state, and Oxa’s classic vitals: heart rate, heart rate variability, and breathing rate.
To understand how your sleep is changing over time, you can filter sleep trends by the current week, month, season, or year. While tracking more nights gives Oxa optimal data to assess, Oxa starts to understand and report your personal sleep trends after just 3 nights. For each subsequent time period, a sleep trend is visible after just one night. After a break, record a new sleep session to update your sleep trends for the current time period.
The Sleep health score is your main guide to understanding the quality of your sleep with Oxa. It gives you a comprehensive view of your night, calculated from sleep duration, the number of position shifts, and the calmness level while asleep. Sleep health display the following submetrics:
- Sleep duration: the time you spent asleep: from the moment you drift off until you wake up. The amount of sleep one gets can greatly affect their physical well-being, mental health, and daytime energy levels. Oxa’s sleep benchmarks are based on the US CDC’s guidelines: How Much Sleep Do I Need?
- Position shifts: the number of times you change position during the night. It is important for promoting comfort, improving sleep quality and addressing specific sleep-related concerns, such as sleep apnea or snoring.
- Asleep calm: your average level of calmness throughout the night. Determined by analyzing your heart rate and heart rate variability (HRV), Asleep calm provides insight into the state of your nervous system, thereby shedding light on your sleep quality. A calmer sleep typically leads to a more restful and rejuvenating rest.
Bedtime state shows how restful you were before you fell asleep. Your Bedtime state score indicates your level of preparedness for sleep. This score is derived from your calmness just before falling asleep and the time it took for you to fall asleep.
- 'Asleep in': the duration taken to transition from being awake to falling asleep after you get into bed. Ideally, this period should be within 10-15 minutes, signifying a balanced sleep cycle. Falling asleep in less than 8 minutes might indicate sleep deprivation. These values are based on guidance from the National Sleep Foundation and AASM. Taking more than 20 minutes to fall asleep? Consider trying Oxa's resonance to sleep exercises to ease your transition into sleep.
- Bedtime calmness: how calm you were right before falling asleep. It is calculated from your heart rate, breathing rate and heart rate variability (HRV) and indicates the state of your nervous system on a scale of 1 to 10.
How to navigate Oxa’s sleep trends
To access sleep trends, open the Sleep tab and select See trends, or scroll to the bottom of a sleep session summary and select See trends.
The main sleep trends view displays an overview of your sleep health, bedtime state, and vitals. Tap to select any of the parameters to see more details. Selecting Sleep health opens a detailed view of your sleep duration, position shifts, and asleep calm. Selecting Bedtime state opens a detailed view of the time it takes you to fall asleep and your calmness before falling asleep. Tap the back arrow in the top left corner to return to the sleep trends homescreen.
To change the time period that you are viewing your sleep trend, tap the time durations (Week, Month, Season, or Year) from the top of any sleep trend window.
The Sleep trend scores includes colored equalizer bars, depicting the sleep submetrics. The height of the bars indicates the health of each parameter. The color of the bars visually represents the range from Optimal to Poor. These colors are consistently used across the app — for scores, in graphs, and on the metric cards as well.
If Oxa’s sleep trends display no data or insufficient data:
- Sleep with Oxa for at least one more night. The more times you track your sleep with Oxa, the more precise your sleep trends become. Sleep trends are activated after 3 sessions of more than X hours.
- Reduce the interval of time to the period when you tracked your sleep with Oxa. The selected time duration (week, month, etc.) needs to have at least one sleep session to display a trend.
- Check that your vitals are appropriately tracked during each individual sleep session.
