A bad sleep score generally indicates poor sleep quality and insufficient rest. Different sleep tracking devices and apps use varying scoring systems, but a score consistently below 60 is often considered a bad sleep score. This suggests you aren't getting the restorative sleep your body needs.
Understanding Sleep Score Ranges
Sleep scores are usually presented on a scale, often from 0 to 100. While the exact ranges may differ slightly depending on the device or app (Fitbit, Garmin, etc.), a common interpretation is:
- Excellent: 90-100
- Good: 80-89
- Fair: 60-79
- Poor: Less than 60
As seen in the Fitbit app (https://support.google.com/fitbit/answer/14236513?hl=en), a score below 60 falls into the "Poor" category. Other sources, like Firstbeat (https://www.firstbeat.com/en/blog/a-good-nights-sleep-what-does-it-mean/), may define poor sleep as a score between 0-49. The key takeaway is that a consistently low score signifies a need for sleep improvement. A high sleep score (90-100) indicates well-restedness and preparedness for the day (https://www.garmin.com/en-US/blog/health/new-data-examines-quality-of-garmin-users-sleep/).
While a few low scores might not be alarming, a pattern of consistently low scores warrants attention (https://www.sleep.com/sleep-app/how-to-improve-your-sleepscore).
