The Sleep 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)
• Overnight Heart Rate (overall heart rate)
• Overnight Heart Rate Variability (measurement of fluctuations in 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.

Notes:

• A lower heart rate generally suggests better cardiovascular health and recovery.
• A higher HRV often means your body is recovering well from stress or activity.
