Heart Rate Variability (HRV) Chart Guide
Please note that HRV is only available for iOS devices.
Blue dots: Represent Sleep HRV.
Higher sleep HRV: Indicates better recovery, leaving you mentally and physically ready for the day ahead.
Lower sleep HRV: Suggests your body is struggling to recover effectively.
Temporary dips in Sleep HRV are normal, but consistently low values may mean your body needs extra support. Consider resting more, improving sleep hygiene, managing stress, or adjusting your exercise.
Highlighted area: This is your Typical HRV Range, the target zone for your Sleep HRV.
Tracking your Sleep HRV against your Typical Range helps you understand how well your body is recovering and recognize when you might need additional rest or support.
Keep in mind that HRV is highly individual - what's considered "low" for one person may be normal for another. The key is to observe patterns in your own HRV trends over time rather than comparing them to others.
