How accurate is Apple Watch HRV?
Recently, researchers at the University of Zaragoza in Spain published a paper showing that RR intervals extracted from the Apple Watch while using the Breathe app, are indeed very accurate (Hernando et al., “Validation of the Apple Watch for Heart Rate Variability Measurements during Relax and Mental Stress in Healthy ….
Why is my HRV lower at night?
For many people this is the most active time of day, so it’s not surprising that the body’s rest and digest is mostly switched off during this period. Both the mean (average) value of HRV and the night-day variation reduce as we get older. This parallels our reduced ability to recover as we age.

What affects your HRV?
The HRV level changes naturally from day to day, based on the level of activity and amount of, for example, work-related stress, but if a person is chronically stressed or overloaded – physically or mentally – the natural interplay between the two systems can be disrupted, and the body can get stuck in a …
Is HRV on fitbit accurate?
Most watches, armbands, and fitness heart rate trackers are designed for heart rate only. This means that they do not accurately measure R-R intervals. R-R intervals are the exact time measurement in milliseconds between each heartbeat that are needed for truly accurate Heart Rate Variability (HRV) calculations.
Is it better to have a high or low HRV?
Higher HRV (or greater variability between heart beats) usually means that the body has a strong ability to tolerate stress or is strongly recovering from prior accumulated stress. At rest, a high HRV is generally favorable and a low HRV is unfavorable.
Should I worry about low HRV?
Chronically low Heart Rate Variability is generally not favorable. However, a single or handful of low HRV readings is not always bad. In fact, strategic acute drops in HRV can be favorable as long as HRV recovers to normal or better levels.
What is a good HRV for my age?
The middle 50% of 20-25 year olds usually have an average HRV in the 55-105 range, while 60-65 year olds tend to be between 25-45.
What is a good heart rate variability while sleeping?
During sleep, expect your heart rate to drop to the low end of your normal: If your normal daytime resting heart rate ranges from 70 to 85, for example, expect to see a sleeping heart rate of 70 to 75 beats per minute, or even slower.
What if my HRV is low?
Over the past few decades, research has shown a relationship between low HRV and worsening depression or anxiety. A low HRV is even associated with an increased risk of death and cardiovascular disease. People who have a high HRV may have greater cardiovascular fitness and be more resilient to stress.
Does anxiety affect HRV?
Conclusion: Anxiety disorders are associated with reduced HRV, findings associated with a small-to-moderate effect size. Findings have important implications for future physical health and well-being of patients, highlighting a need for comprehensive cardiovascular risk reduction.
What is a good HRV score?
“What is a Good HRV Score for Me?” The average heart rate variability for all WHOOP members is 65 for men and 62 for women. For 25-year-olds it’s 78, for 35-year-olds it’s 60, for 45-year-olds it’s 48, and for 55-year-olds it’s 44.
What is normal HRV range?
Normal HRV can range anywhere from below 20 to over 200 milliseconds, depending on various factors such as age, gender, physical fitness, and genetics. The HRV value provided by Oura falls within this same range. HRV differs for everyone, so be sure to compare changes in your HRV to your baseline and not others.
