Quick introduction: Sleep Summary

The Sleep Summary gives you an overview of your night, including your Sleep Duration, Awakenings, Sleep Stages, Sleep Latency and Efficiency, and more. You can tap any date at the top to switch nights and view insights for a different day. 

You can also swipe left or right to change dates and check the corresponding data for that day.

Metrics and insights available in the Sleep Summary

Self-reported sleep quality

The answer to how you slept.

Heart Rate Variability (HRV)

You'll also find your typical range, and whether your night's HRV falls within that range.

Learn more about Sleep HRV in this article.

Night of Sleep breakdown

• Time in bed (light green): Lying in bed (not sleeping)

• Asleep (green): Actual sleep

• Awake (white): Times you woke up during the night

  

  

Sleep Duration

• Night's Sleep Duration (green column) 
• Recommended Sleep Range (grey shape)

• If your night's Sleep Duration falls within that recommended range at a glance

  

  

Learn more about Sleep Duration in this article.

Awakenings

• The number of times you woke up during the night.

• Benchmark for what's considered ideal (fewer than 2 awakenings per night).

  

  

Sleep Latency

The time it takes you to fall asleep once you start trying. Ideally, this should be under 30 minutes.

Sleep Efficiency

The percentage of time in bed that you spent sleeping. Ideally, this should be above 85%.

Restoration

Time to Low Reactivity

The time it takes your body to drop below Homeostasis once you start trying to fall asleep. Ideally, you reach Low Reactivity within 30 minutes of getting into bed.

• Shorter time: Your body quickly settled into a restorative state, putting more resources toward rest-and-digest. This is a sign of a healthy body. 
• Longer time: Your body struggled to shift enough resources toward restoring itself, which may result in poor sleep quality.

Percentage of time in Low Reactivity

The total amount of time in bed that your body spent in a calm, restorative state. More time in Low Reactivity means more opportunity for your body to rest, repair, and recover.

Ideally, you should spend about 90-100% of your time in bed in Low Reactivity.

Learn more about the Reactivity Monitor in this article.

Awakening Stage

The Sleep Stage you wake up in. Ideally, you should wake up while on Light Sleep. 

Deep Sleep is the most difficult stage to wake up from. If this happens, you will likely experience sleep inertia or mental fogginess. 

Sleep Stages

Awake, REM, Light, Deep, and Undefined, shown as both percentages and total time.
