Is the 47 HRV good?

“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 a good average HRV?

Why is my HRV so low on Apple Watch?

On the flip side, a low HRV (at rest) can indicate that your body is less adaptive/resilient and may be a sign of health problems or potential health issues in the future.

Is higher HRV better?

High HRV is generally considered an indicator of a healthy heart, and higher HRV has been found in many studies to be associated with reduced morbidity and mortality and improved psychological well-being and quality of life.

What is considered low HRV?

HRV can be broken down into four frequency domains: ultralow (<0.003 Hz), very low (0.0033-0.04 Hz), low (0.04-0.15 Hz) and high (0.15-0.40).

What is a good HRV for a 40 year old male?

For someone with a chronological age of 40, the average HRV is 65*. Higher aerobic fitness levels often translate into higher HRV scores, so many endurance athletes will be up towards, or even beyond the green line, i.e. 80 or above.

How often does Apple Watch measure HRV?

As you exercise, work, or even take a minute to cycle through the Apple Watch Breathe app, an HRV is collected throughout the day from the Apple Watch — likely without someone knowing. Yet even though the measurement is captured through your Apple Watch, it’s stored on your iPhone.

What is HRV on Apple Watch?

What is a good HRV rate 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.

Does alcohol affect HRV?

Heart rate variability (HRV) and resting heart rate are two of the most useful metrics for quantifying your fitness on a daily basis. Consuming alcohol causes your HRV to drop (bad) and your resting heart to rise (also bad).
