Heart rate variability (HRV) is a fascinating and important health metric that reflects the state of our autonomic nervous system (ANS).
It’s a great way to understand how well our bodies are balancing stress and relaxation.
Letโs explore HRV trends across different ages, why they matter, and let’s find out what is a good HRV score.
What Is Heart Rate Variability (HRV)?
HRV measures the time variation between consecutive heartbeats in milliseconds. This variation reflects the balance between the parasympathetic (rest-and-digest) and sympathetic (fight-or-flight) nervous systems.
A higher HRV indicates a well-functioning ANS and suggests that you are fit, well-rested, and adequately recovered. On the other hand, lower HRV can indicate chronic stress or potential health issues.
What Is Genuinely a Good HRV?
A โgoodโ Heart Rate Variability (HRV) can differ depending on several factors such as age, fitness level, and overall health.
Vera K. Jandackova in her study says that a generally healthy HRV ranges from 60 to 100 milliseconds (ms).
However, this range is influenced by your age, as HRV tends to naturally decline as we get older.
Average HRV by Age Group
As shown, HRV decreases with age, mainly due to reduced parasympathetic nervous system activity, which is responsible for the bodyโs relaxation response. This decline can be more significant in people with chronic conditions or those who lead sedentary lifestyles.
Fitness Level and HRV
Your fitness level also plays a big role in HRV. Regular exercise, especially high-intensity interval training (HIIT), can boost your HRV. Engaging in physical activity strengthens heart health and leads to higher HRV, signaling better adaptability to stress and a more robust cardiovascular system.
Your overall health also impacts HRV. Chronic conditions like heart disease, diabetes, and lifestyle habits such as smoking, poor diet, and excessive alcohol consumption can lower HRV. These factors decrease the body’s ability to regulate itself efficiently.
HRV Chart for Men and Women Based on Age
“HRV is highly individualized, fluctuating daily and from person to person. What is considered a healthy heart rate variability differs for everyone,”ย says Poonam Desai, M.D., an integrative physician focusing on longevity medicine.
Here’s the Heart Rate Variability Chart by age:

Exploring the key trends in Heart Rate Variability by age reveals important patterns that can help us better understand our body’s response to stress and recovery throughout different stages of life.
1. Rapid Decline in Early Adulthood
According to NIH, HRV decreases rapidly between the ages of 20 and 40. This decline is more pronounced in men, who typically have higher HRV than women until around age 50. The early decline may be linked to increasing responsibilities, stress, and lifestyle changes that often occur during these years.
This period also coincides with a natural reduction in physical activity and changes in sleep patterns, which can negatively impact HRV.
2. Leveling Out in Middle Age
After 40, the rate of HRV decline slows down, and differences between men and women diminish. By age 50, both sexes tend to have similar HRV values. This stabilization might be due to more consistent lifestyle habits and improved stress management strategies as people age.
Additionally, many individuals in this age group become more health-conscious, incorporating regular exercise and better dietary habits into their routines.
Why Higher HRV Matters
A higher HRV means that your parasympathetic and sympathetic nervous systems are in balance, which is crucial for overall health and well-being. This balance helps your body efficiently switch between states of relaxation and readiness, essential for coping with daily stressors.
A well-functioning nervous system also supports optimal digestion, immune function, and sleep quality.
Sign of Fitness and Recovery
People with higher HRV are generally fitter and better rested. They can handle physical and mental stress more efficiently. Higher HRV is often seen in individuals who engage in regular physical activity and prioritize recovery practices.
Additionally, it reflects good cardiovascular health, as the heart is able to adapt quickly to varying demands.
Health Indicator
Consistently low HRV can signal chronic stress, increasing the risk of heart attack, stroke, and other health problems. Low HRV is also associated with mental health conditions such as anxiety and depression.
Monitoring HRV can thus serve as a valuable tool for early detection and intervention, helping to mitigate long-term health risks.
Factors Influencing HRV
Several factors can significantly impact heart rate variability, making it essential to understand what influences these fluctuations in order to maintain or improve overall health.
Genetics
Your genetic makeup plays a significant role in determining your HRV. Some people naturally have higher or lower HRV. Genetic predispositions can influence how your body responds to stress and recovers from it. Understanding your genetic tendencies can help tailor lifestyle choices to optimize HRV.
Age and Sex
HRV decreases with age, and men usually have higher HRV than women until about age 50. Hormonal differences and varying stress levels between sexes contribute to these disparities. Post-50, hormonal changes, particularly in women, tend to equalize HRV levels between sexes.
Health Conditions
Conditions like cardiac arrhythmia can significantly affect HRV. Other chronic illnesses, such as diabetes and hypertension, also negatively impact HRV. Regular monitoring can help manage these conditions by providing insights into how lifestyle changes impact overall health.
Hormonal Changes
Menstruation, pregnancy, and menopause can influence HRV in women. Hormonal fluctuations can cause temporary changes in HRV, reflecting the bodyโs adaptive mechanisms. Awareness of these changes can help in better-managing health and well-being during these phases.
Stress and Mental Health
When you’re stressed, your body’s fight-or-flight response becomes more active, reducing parasympathetic activity and, in turn, lowering HRV according to NCBI. Practices like mindfulness, meditation, and adequate sleep can help manage stress levels and improve HRV, contributing to better mental and physical well-being.
How to Improve HRV
- Engage in practices like gratitude journaling and mindfulness meditation. These activities help reduce stress and improve HRV.
- Using saunas and ice baths can stimulate your ANS and improve HRV.
- Building strong relationships and a supportive social network enhances your mental and emotional well-being, positively impacting HRV.
- Simple breathing exercises can quickly relieve stress and boost HRV.
- A balanced, whole-food diet supports overall health and helps maintain a good HRV.
- Regular, quality sleep is crucial for recovery and maintaining a high HRV, as stated by NIH.
- Engage in regular physical activity, but be cautious of overtraining, which can negatively impact HRV.
- Proper hydration is essential for maintaining good HRV. Supplement with electrolytes if needed, especially during intense exercise or hot weather.
Final Words
By understanding the trends and factors that influence HRV, you can take proactive steps to improve it and enhance your health. Monitoring HRV doesnโt have to be complicatedโsimple daily practices can lead to significant improvements.
