The Sleep Quality Score is a very simple and intuitive way to understand how well you slept. It measures every night's sleep from the last 30 nights and provides a score out of 100 points based on 4 key inputs:

• Duration (total time spent sleeping)
• Depth (part of night spent in restorative phases, deep sleep)
• Regularity (consistency between your bed- and rise-times)
• Interruptions (time spent awake)

These metrics can be imported from Apple Health or Health Connect:

• Overnight Heart Rate (overall heart rate)

Sleep duration and depth are the most important factors for raising sleep score. The key factors in the sleep score are sleep regularity and sleep hygiene. An improvement in these hygiene measures will improve the overall sleep experience.
