Sleep Heart Rate Variability (HRV)

Heart Rate Variability measures the variation in time between each heartbeat. It is recorded during sleep and reflects how well your body recovers overnight.

How to read the Sleep HRV chart

Sleep HRV

The blue dots represent your Sleep HRV each night. The chart helps you understand how well your body restores itself.

• Higher Sleep HRV: Your body recovered well overnight and is prepared for the day.
• Lower Sleep HRV: Your body may be recovering less effectively.

Temporary dips are common. However, consistently low values may indicate that your body needs more rest or support. You may want to focus on sleep quality, stress management, or adjusting physical activity.

Typical HRV Range

Your Typical HRV Range is the highlighted area and reflects what is normal for you when your body is functioning well. Comparing your sleep HRV to this range helps you understand your recovery needs.

HRV is highly individual. A “low” HRV for one person may be normal for another. What matters most is your own trend over time.

Wear requirements

You need at least 10 days of wear in the last month to see your Typical HRV Range.
