• Heart rate variability (HRV) is a highly sensitive, individual metric that can indicate autonomic nervous system function.
  • From looking at a heart rate variability chart, you can see the average HRV based on your age and gender.
  • Monitor your HRV on Oura to understand what’s “normal” for you.

What’s a good heart rate variability (HRV) for women? What’s a good HRV for men? 

Trick question! There’s not an “optimal” HRV for men, women, or even a certain age group. HRV is a highly sensitive, individual metric that varies from person to person, and can change daily, or even hourly. (Learn more about HRV here.) 

“HRV is highly individual, so you should compare your HRV to your own averages over time to gain a sense of what’s normal for you,” says Marco Altini, an HRV expert, data scientist, and Oura advisor. “Plus, keep in mind that it’s normal to see daily and seasonal fluctuations in your HRV.” 

The best way to determine your normal HRV level is to use a wearable, like the Oura Ring, that measures your HRV in a controlled setting, such as overnight as you sleep, and establishes a baseline over a few weeks. That said, based on community data, Oura data scientists have found a range of normal HRV scores across Oura members, and we can see interesting trends across age and gender.

What Impacts HRV? 

Quick refresher: Heart rate variability (HRV) measures the variation in milliseconds between your heartbeats. HRV is linked to your autonomic nervous system (ANS) and the balance between the parasympathetic (rest-and-digest) and sympathetic (fight-or-flight) branches. “What we measure at Oura is largely parasympathetic activity, due to how the parasympathetic system impacts heart rate beat-by-beat,” explains Altini.  

As a general rule of thumb: 

  • Higher HRV is associated with rest-and-digest, general fitness, and good recovery
  • Lower HRV is associated with fight-or-flight, stress, or illness 

Again, HRV differs greatly from person to person — and day to day. A lower HRV does not mean that you’re unfit with a low HRV, nor is the opposite necessarily true.

Heart Rate Variability Chart: Median HRV Across Oura Members by Age and Gender

Below, we’ll see the range of HRV scores across Oura members by age and gender.

Chart: What is the Median HRV Across Oura Members?

As this chart shows, the general takeaway is that HRV is much higher for younger people than older people. Multiple, population-based research studies confirm that HRV tends to decline with age. Some research suggests that this decline likely reflects the normal aging process. 

Other studies show this decline in HRV may be less severe the healthier the person is. “With the right lifestyle and genes, there can be a lower reduction or higher values because they had a higher HRV over their lifespan,” Altini explains. (See below for healthy lifestyle habits that can help improve your HRV.) 

Average HRV for Women

HRV Distribution for Women

The median HRV (which marks the middle of the distribution) for women is 35, while the mode HRV (the most commonly occurring score) is 27.

Average HRV for Men

HRV Distribution Among Men

The median HRV for men is 38, while the mode is 27.

Improving Your Unique HRV Score

While your HRV is specific to you and you alone, there are some factors within your control that can impact your score. These factors include your sleep hygiene (i.e. a cool, dark room and comfortable bed), your nutrition (including caffeine, alcohol, and hydration), your stress levels, and your physical fitness. 

Other factors impacting HRV are harder to control. This includes things like your age and gender, hormonal cycles, or stress from work or family.

While the goal with HRV isn’t to make yours as “high” as possible, having more consistent HRV values from day to day can signal an enhanced ability to respond to daily stressors, Altini explains. There are a few ways you can make your HRV values more consistent, including staying active, eating well, and deep breathing techniques. Find more tips here.  

Finally, keep in mind: “It’s important to experiment and see what works for you, your body, and your lifestyle,” Altini points out. “Improving our physiology takes time; each of these habits might take several weeks to build and deliver benefits, but exploration will help you find what’s best for your health.” 

Note that HRV charts include 99.5% of Oura members. The top 0.5% of users are truncated to cut remove extremely high HRV scores (which reach almost to 250).
