Key Takeaways
- HRV tends to decrease with age, with a more pronounced decline occurring between the ages of 20 and 40, stabilizing afterward.
- Men typically have higher HRV scores than women until around age 50, after which the differences tend to equalize.
- Individuals with higher fitness levels, especially endurance athletes, often exhibit significantly higher HRV scores compared to the general population.
- Higher HRV may indicate greater cardiovascular fitness and resilience to stress.
HRV Importance
Heart Rate Variability (HRV) is a crucial indicator of your overall health and wellbeing. It measures the variation in time between each heartbeat - a higher HRV is generally associated with better cardiovascular fitness and resilience to stress.
Most importantly, HRV is a reflection of how well your autonomic nervous system is functioning. This system controls vital bodily functions such as heart rate, digestion, and respiratory rate, so keeping it in good shape is essential for overall health.
Measuring HRV Score
It's usually measured in milliseconds and can be tracked using various devices like fitness trackers and specialized HRV monitors. Most commonly, people use devices, including smartwatches like Apple Watches or smart rings like Oura, that sync with their apps to provide real-time HRV data. You should measure HRV consistently, preferably at the same time each day, to get accurate readings.

Factors Affecting HRV Score
Age Impact
Age is one of the most significant factors affecting HRV. A 2020 research done using Fitbit data from 8 million users found that HRV tends to decrease with age. This decline is more pronounced between the ages of 20 and 40, after which it tends to stabilize.
The study found that HRV score still dwindled as age progresses, regardless of the gender.
For example, teenagers might have an HRV of around 80 ms, while those over 75 years old might have an HRV of around 25 ms.
Gender Differences
Gender also plays a role in HRV scores - generally, men have higher HRV scores than women until around the age of 50. After this age, the differences tend to equalize. This was confirmed by the Elite HRV app, which analyzed data from over 24,000 users and found that younger males had higher HRV scores compared to females of the same age.
The Elite HRV user base isn't a perfect reflection of the general population. Since they have more elite and recreational athletes, who usually have higher HRV scores, the sample statistics might differ slightly from some medical studies.
Lifestyle Choices
Your lifestyle choices can significantly impact your HRV score too.
Regular physical activity, a balanced diet, and adequate sleep are all factors that can positively influence your HRV. For instance, endurance athletes often exhibit significantly higher HRV scores compared to the general population. This is because regular exercise enhances cardiovascular fitness and autonomic nervous system balance.
On the other hand, poor lifestyle choices such as smoking, excessive alcohol consumption, and a sedentary lifestyle can lower your HRV. These behaviors increase stress on your body and negatively affect heart health, leading to reduced HRV scores.
That said, some stress can still be beneficial for your HRV score. Hormetic stressors (controlled, acute stressors that trigger beneficial adaptive responses in the body) such as intermittent fasting, cold exposure such as cryotherapy, and heat exposure such as sauna can make the body more resilient - and ultimately, boost HRV scores too.
Ice bath can strengthen the cardiovascular and nervous systems - leading to higher HRV score.
Environmental Factors
Environmental factors like air quality, temperature, and noise levels can also impact your HRV. Poor air quality can stress your respiratory and cardiovascular systems, leading to lower HRV scores.
Besides that, noise pollution can disrupt your sleep and increase sympathetic activity, both of which can negatively impact your HRV. Therefore, it's essential to consider your environment when trying to improve your HRV.
HRV Chart by Age and Gender
Below are the average HRV scores for men and women across various age groups. These values provide a benchmark for what is considered normal, helping you set realistic goals for improving your HRV.
- Men typically have higher HRV scores than women until around age 50.
- HRV tends to decrease with age, stabilizing after 40.
- Fitness levels can significantly impact HRV, with athletes often showing higher scores.
Here are the average HRV results taken from the Fitbit clinical study - these are average values, and individual HRV can vary widely:
Average HRV Score for Men

HRV Variations in Different Age Groups
It's clear that HRV scores vary significantly across different age groups and between genders. These variations can help you understand what a good HRV score is for you, depending on your age and gender. For example, if you're a 35-year-old male, an HRV score of 49 ms would be considered average.
Besides that, understanding these norms can also help you set realistic goals for improving your HRV. If your HRV is below average for your age group, you might want to focus on lifestyle changes to boost it.
Interpreting HRV Scores
Interpreting your HRV scores can be challenging, especially if you're new to tracking this metric. However, understanding what constitutes a healthy HRV range and setting personalized goals can make the process easier.
Healthy HRV Range
A healthy HRV range varies from person to person, depending on factors like age, gender, and fitness level. Generally, higher HRV scores indicate better cardiovascular fitness and a well-functioning autonomic nervous system. For example, an HRV score of 70 ms for a 25-year-old male would be considered healthy.
Personalized HRV Goals
Setting personalized HRV goals can help you improve your overall health. Start by tracking your HRV consistently for a few weeks to establish a baseline. Then, make lifestyle changes such as increasing physical activity, improving your diet, and reducing stress to see if your HRV improves.
The goal is not to achieve a specific number but to see positive trends over time. If your HRV is consistently improving, it indicates that your overall health is also improving.
Benefits of Tracking HRV
Tracking your HRV can offer numerous benefits that contribute to your overall health and wellbeing. By understanding your HRV, you can make informed decisions about your lifestyle and take proactive steps to improve your health.
Stress Management
One of the primary benefits of tracking HRV is its potential to help manage stress. HRV is a reliable indicator of how well your body is coping with stress: higher HRV scores generally indicate that your body is more resilient to stress, while lower scores suggest that you may be experiencing higher levels of stress.
Here’s how Pulsetto helps with stress management.
