Troubleshooting Missing Sleep Data or Seeing Gaps in Graphs

Missing Sleep Data

If you're missing sleep data, your ring's battery level may have been too low when you fell asleep. When this occurs, you'll see your bed and wake-up times, but you won't receive Oura's typical sleep stage breakdown for the previous night.

To avoid missing out on Oura's sleep stage analysis, ensure that your ring's battery level is at least 20% prior to going to bed.

Gaps in Heart Rate Variability and Resting Heart Rate

If you spot gaps in your resting heart rate (RHR) or heart rate variability (HRV) graphs, something may have interfered with your pulse monitoring.

Possible causes for these gaps are listed below:

  1. Your ring was too loose. Before going to bed, ensure your ring's LED sensors are underneath your finger and your ring fit feels snug. If your ring feels too loose, try wearing it on a different finger.
  2.  The LED sensors were dirty. You can wash the sensors and your ring using water and soap. Dry the ring thoroughly with a soft cloth before placing it back on your finger.
  3.  You were restless during the night. The ring picks up even the slightest of movements, so tossing and turning may lead to gaps in your data. Use Oura's Nighttime Movement feature to keep an eye on restlessness during your nights.
  4.  You slept in a position that caused your hand to go numb (causing partially blocked blood circulation).
  5.  Your resting heart rate was exceptionally low (below 33 bpm).
  6.  Arrhythmia, or an irregular heartbeat, resulted in incomplete data.

Here’s how gaps might appear in the Oura app:
