Have you ever wondered what is considered ‘good’ HRV and for you, personally? You are not alone! Today HRV is a widely recognized standard for tracking the vagus nervous system health and stress management. To obtain good health, it is necessary to learn how HRV levels can be increased, thus leading to a more stable condition, enabling you to stay calm, flexible and focused.

Below is a scientifically proven step by step guide with instruction,

What is HRV

HRV (Heart Rate Variability) is the time variation between each heartbeat, defined by the number of times your heart beats in a minute. Thus, HRV indicates how flexible it is also known as Interbeat intervals.

HRV is controlled by the Autonomic Nervous System which can be divided into two parts:

  • Parasympathetic Nervous System– “Rest & Digest” helps you to stay calm and focused and is usually associated with High HRV levels
  • Sympathetic Nervous System – “Fight-or-Flight” triggers a high adrenaline emergency response and is usually associated with Low HRV levels

HRV reflects Stress, Recovery and Cardiovascular fitness of the body also framed as the body’s internal stress meter. A low HRV can best be described as a warning sign, related to chronic stress, dehydration, mental burnout and poor sleep quality.

The vagus nerve plays a key role in calming the body. It activates the parasympathetic system helping you relax and recover. The goal is to manage stress by enabling you to bounce back quickly.

Ways to Improve HRV

To improve HRV it is more important to build consistent habits in order to effectualize recovery of your body from stress.

Below are listed effective and scientifically proven ways to improve your HRV significantly:

Quality Sleep

Sleep is considered the leading factor affecting HRV. Poor or inconsistent sleep can lower you HRV and increase stress levels.

  • Try to maintain a consistent sleep schedule
  • Avoid screen time prior to bedtime
  • Aim for 7-8 hours of sleep

Coherent Breathing

Breathing exercise directly stimulates the vagus nerve which activates the parasympathetic nervous system, leading to a significant increase in HRV.

  • Try 5-6 breathing pattern (inhale for 5 seconds, exhale for 6 seconds through your nose)
  • Practice it for 20 minutes daily for better results

Follow this simple guided breathing exercise to activate vagus nerve and improve HRV in just a few minutes. https://youtu.be/orqPrUcVEhs?si=CLZJCr7ZC2aMCbhD

Regular Exercise

Physical exercise strengthens your cardiac system and improves HRV significantly.

  • Include moderate exercise (cycling, training, walking) in your daily life
  • Allow time for rest and recovery

Over-training without proper recovery can lowers HRV

Daily Stress Management

Stress can keep your sympathetic system activated, which can lower your HRV.

  • Meditation
  • Yoga
  • Staying in nature

These practices activate the parasympathetic system, helping your body shift out of fight-or-flight mode.

Stay Hydrated

Your internal system can directly affect HRV. Dehydration reduces blood volume, making your heart work harder and lowering HRV

  • Drink plenty of water (around 2-3 litres daily
  • Limit processed food

Take Short Breaks for Recovery: 

Your body is in its biological nature not designed to stay stressed for long periods of time

  • Take 2-5 min breaks in-between your work schedule
  • Go for a small walk

Your HRV levels can determine when you need a break. You can check it through Sumondo where you also get introduced to a 3 minutes exercise to calm you down and maintain your HRV levels.

Is Your Tracker Accurate?

Not all HRV trackers are created equal. The majority of smart watches and fitness bands give you an HRV reading, but its accuracy may vary according to the quality of technological functionalities. Most wearable devices use optical sensors (PPG) for measuring HRV. They seem convenient but the readings can be affected by the body’s movement and how tightly you wear the device.

For reliable data, you need built specifically for this and is medically certified. So, if you have been tracking your HRV on a random smartwatch and wondering why the numbers feel inconsistent — your tracker might be the problem, not your health.

This is where the Sumondo app stands out. The app is built specifically for HRV monitoring and stress detection. It is clinically tested and holds a Class I medical device certification, and meets the standards required for medical-grade accuracy. It measures your heart rate and HRV accurately and displays your stress levels clearly in real time.

Decoding Your HRV Values – What is Good HRV for Your Age?

One of the most common questions people ask is: “What should my HRV number ideally be?” The answer is highly subjective as it depends on age, fitness routine, and even the time of day you measure.

Below is a general reference guide:

  • 20s: 55–105 ms
  • 30s: 45–90 ms
  • 40s: 35–80 ms
  • 50s and above: 25–65 ms

HRV naturally declines with age, so avoid comparing your number to a 25-year-old athlete. What matters is your own baseline and whether it is trending upward over time.

This is where the Sumondo app becomes your personal HRV coach. Once it detects your stress levels, it does not just leave you with a number — it actively suggests ways to bring your

HRV back to a healthy range, including:

  • 3-minute breathing exercises to stimulate your vagus nerve and calm your nervous system instantly
  • Guided meditation to shift your body out of fight-or-flight mode
  • Movement exercises to get your body active and improve recovery
  • Daily reminders to measure your HRV consistently so you can track your progress over time

Think of Sumondo as a tool that not only tells you where your HRV stands but also shows you what to do about it — right in that moment.

Final Thoughts

HRV is one of the most powerful indicators of your body’s overall health, but only if you measure it accurately and act on the insights it provides. Start small, stay consistent, and let the data guide your progress.
