Troubleshooting Gaps in HRV and Resting Heart Rate Graphs

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 Oura 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:
