A low Recovery Score means one or more of the available overnight signals were less favorable than your recent context. It does not identify a cause, diagnose illness, or automatically mean you should skip training.
Open the breakdown first
The overall score can include your Sleep Score, heart rate variability, resting heart rate, and respiratory rate. The exact breakdown depends on what your connected source recorded that night.
Look for the component that changed most clearly. A low score driven mainly by sleep calls for a different review than one accompanied by unusual heart-rate or respiratory data.
Check whether the data is complete
Before interpreting the score, open the same night in Apple Health or your connected health platform. Confirm that:
- the full sleep period is present;
- the watch or device was worn securely;
- HRV, resting heart rate, and respiratory rate were recorded where expected;
- the date and time zone are correct; and
- Zolt still has permission to read the records.
A partial night, charging gap, loose fit, or source-permission issue can leave the breakdown incomplete. Missing data and a genuine change in your signals are different problems.
Think in context, not causes
Hard training, poor sleep, alcohol, illness, travel, stress, and ordinary day-to-day variation can coincide with a lower score. The score cannot determine which explanation applies.
Compare the result with how you feel and with recent sleep and training. One unusual morning may be noise or a temporary response. A pattern across several complete nights is more useful context.
What to do today
If you feel normal and the source data is complete, note the result and use your planned session, recent cardio load, and perceived effort to guide the day. You may choose an easier session, but the score does not prescribe one.
If you feel unwell, have unusual pain, or notice concerning symptoms, respond to those symptoms instead of trying to improve the number. Seek appropriate medical guidance when needed.
If the score still looks wrong
- Identify the component that pulled the breakdown down.
- Compare it with your own recent values.
- Check the original record for the same night.
- Confirm the device, permissions, date, and time zone.
- Compare the next complete night.
If the source record is complete but Zolt shows a different or missing value, contact support with the affected date and screenshots of both views.
