1. Get Better Sleep
Quality sleep is one of the most effective ways to improve your HRV.
When you sleep, your body goes into repair mode, helping to restore and rejuvenate your systems. This was proven in a 2022 study - it found that better sleep quality was positively correlated with higher HRV, indicating that disturbances in sleep could lead to impaired autonomic regulation.
So, aim for 7-9 hours of sleep per night. Create a bedtime routine that helps you wind down, such as reading a book or taking a warm bath.
For example, Bryan Johnson has his own sleep routine such as avoiding mental stimulants like coffee and alcohol and sleeping with blacked out windows for complete darkness.
2. Practice Breathing Exercises
Breathing exercises are a simple yet powerful way to improve your HRV - they help activate the parasympathetic nervous system, which promotes relaxation and recovery.
In fact, a 2022 study compared different breathing techniques and found that "low and slow" breathing (at 6 breaths per minute) led to greater increases in HRV compared to deeper breathing or no paced breathing.
This technique is known as slow-paced diaphragmatic breathing - it involves taking deep breaths using your diaphragm rather than shallow breaths using your chest. Aim for 5-7 breaths per minute.
Try to incorporate mindful breathing into your daily routine - take a few deep breaths before starting a new task or when you feel stressed. This practice can help keep your HRV high throughout the day.
3. Maintain a Balanced Exercise Routine
Exercise is crucial for improving HRV, but it's essential to strike a balance: overtraining can lower HRV, so it's important to mix different types of workouts and include rest days.
Aerobic Exercises
Aerobic exercises, such as running, cycling, and swimming, are excellent for boosting HRV. Aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity per week.
Strength Training
Strength training also has benefits for HRV - it helps build muscle, improve metabolism, and support overall cardiovascular health. Incorporate strength training exercises at least two days a week.
Importance of Rest Days
Rest days are just as important as workout days. They allow your body to recover and prevent overtraining, which can lower HRV. Make sure to include at least one or two rest days in your weekly routine.
4. Focus on Nutrition
A 2018 study published in the journal of Behavioral Pharmacology indicated that healthy diet habits such as following a Mediterranean diet, taking adequate omega-3 fatty acids, B-vitamins, probiotics, polyphenols, and losing excessive weight, is associated with improved HRV. This diet's anti-inflammatory properties contribute to better autonomic function and cardiovascular health.
It's beneficial to avoid eating 3-4 hours before bedtime to improve sleep quality. Additionally, the timing of meals can help maintain circadian rhythms, further enhancing HRV.
Avoiding Processed Foods
Another effective way to improve your heart rate variability is by avoiding processed foods, fast food, sugary snacks, and pre-packaged meals. Processed foods are often high in unhealthy fats, sugars, and sodium, which can negatively impact your cardiovascular health and HRV. Instead, focus on whole, unprocessed foods.
5. Stay Hydrated
Hydration is key to maintaining a high HRV. Water is essential for all bodily functions, including heart health. Dehydration can lead to decreased blood volume, making your heart work harder and lowering your HRV.
A 2023 systematic review and meta-analysis looked at how hydration affects heart rate (HR), HRV, and blood pressure during and after exercise. The findings showed that drinking fluids reduced the rise in heart rate during exercise and helped the body recover better by speeding up the heart's response after exercise.
Aim to drink at least 8-10 glasses of water per day. If you're active or live in a hot climate, you may need even more. Carry a water bottle with you and take sips throughout the day to stay hydrated.
Watch for signs of dehydration, such as dark urine, dry mouth, and fatigue. If you notice these symptoms, increase your water intake immediately. Staying hydrated will help keep your HRV at optimal levels.
6. Manage Stress Levels
A 2018 meta-analysis found that psychological stress is associated with decreased HRV - indicating that stress negatively impacts autonomic regulation. The study emphasized that HRV can serve as a reliable index of stress, with lower HRV reflecting higher sympathetic nervous system activity during stressful periods.
Meditation
Meditation is a powerful tool for reducing stress and improving HRV. Set aside 10-20 minutes each day to meditate - find a quiet space, sit comfortably, and focus on your breath. This practice can help calm your mind and body, boosting your HRV.
Mindfulness Practices
Besides meditation, mindfulness practices can also help manage stress. Try activities like yoga, tai chi, or simply being present in the moment. These practices can help reduce stress and improve your overall well-being, positively impacting your HRV.
Nature Exposure
Research has shown that spending time in nature can reduce stress and improve HRV. Activities like "forest bathing" (also known as “shinrin-yoku” in Japanese) have been associated with lower cortisol levels and enhanced HRV, indicating that natural environments can be beneficial for stress management and autonomic health.
If you find it difficult to meditate, then long walks in the forest is a good way to manage stress and improve your HRV score too.
7. Monitor Caffeine and Alcohol Intake
Caffeine is a stimulant that can increase heart rate and lower HRV. Limit your caffeine intake to one or two cups of coffee per day. Avoid consuming caffeine in the afternoon or evening to ensure it doesn't interfere with your sleep.
Alcohol can also negatively impact your HRV. While an occasional drink may not cause harm, regular or excessive alcohol consumption can lower HRV and lead to various health issues. A study published in the American Journal of Physiology-Heart and Circulatory Physiology discovered that two glasses of red wine can reduce HRV by 28 to 30%.
The recommended alcohol limits for men and women are as follows:
-
Men: No more than two standard drinks per day and less than 15 drinks per week.
-
Women: No more than one standard drink per day and less than eight drinks per week.
8. Gratitude Journaling
Gratitude journaling is a simple yet powerful practice that can improve your HRV. By focusing on the positive aspects of your life, you can reduce stress and enhance your overall well-being.
Set aside a few minutes each day to write down three things you're grateful for. You can do this in the morning to start your day on a positive note or in the evening to reflect on the good things that happened during the day.
9. Maintain a Healthy Weight
Excess weight can put strain on your heart and negatively impact your HRV.
A 2021 review published in the International Journal of Molecular Sciences focused on obesity, nutrition, and HRV found that obesity is associated with decreased HRV, indicating impaired autonomic function. The review emphasized that weight reduction through caloric restriction and exercise can enhance HRV, particularly in individuals with obesity.
Therefore, it's important to achieve and maintain a healthy weight through diet and exercise. Avoid crash diets and extreme exercise routines, as these can be harmful and unsustainable. Instead, aim for gradual, consistent changes - the healthy weight loss range is generally recommended to be 1 to 2 pounds (0.5 to 1 kilogram) per week.
10. Improve Work-Life Balance
Chronic stress from work can lower your HRV and negatively impact your health. This was proven by a study that found long commuting hours and working overtime negatively impacted HRV score. Therefore, it's important to find a balance that allows you to manage work responsibilities while also taking care of your personal well-being.
Setting Boundaries
Setting boundaries is crucial for achieving work-life balance. Clearly define your work hours and stick to them - avoid checking work emails or taking work calls outside of these hours. Communicate your boundaries to your colleagues and supervisors, and don't be afraid to say no to additional work if it will negatively impact your well-being.
Time Management Tips
Effective time management can help you achieve a better work-life balance. Prioritize your tasks and focus on the most important ones first. Break large tasks into smaller, manageable steps. Use tools like calendars and to-do lists to stay organized. Most importantly, make sure to schedule time for relaxation and self-care.
11. Invest in a Quality HRV Monitor
Tracking your HRV can help you understand your health better and make informed decisions to improve it. Investing in a quality HRV monitor can provide you with accurate data and insights.
Choosing the Right Device
Look for devices that are accurate and provide detailed insights into your heart rate variability. Popular options include smartwatches like Garmin, smart rings like Oura, chest straps, and dedicated HRV monitors. Ensure the device is comfortable to wear and suits your lifestyle.
How to Use Data Effectively
Once you have an HRV monitor, the next step is to use the data effectively: regularly track your HRV to identify patterns and trends. Pay attention to how your HRV changes in response to different activities, stress levels, and sleep quality.
Use this information to make informed decisions about your health and lifestyle. For example, if you notice a drop in HRV after a poor night's sleep, prioritize improving your sleep habits.

-
Maintain a consistent sleep schedule
-
Limit blue-light exposure before bed
-
Avoid heavy meals or alcohol late at night
-
Aim for 7–9 hours of quality rest
7. How does breathing influence HRV?
Slow, deep breathing, especially diaphragmatic breathing, activates the parasympathetic nervous system and raises HRV within minutes. Try box breathing (inhale 4s, hold 4s, exhale 4s, hold 4s) or resonant breathing (6 breaths per minute) daily.
8. Can stress reduction improve HRV?
Definitely. Chronic stress keeps your body in “fight-or-flight” mode, suppressing HRV. Effective stress-management practices include:
-
Meditation or mindfulness
-
Spending time outdoors
-
Cold exposure or contrast showers
-
Journaling or gratitude exercises
9. How do devices or wearables track HRV?
Popular devices like Pulsetto, Oura Ring, WHOOP, Apple Watch, and Garmin measure HRV using heart rate sensors or photoplethysmography (PPG). They provide daily HRV scores and trends, helping you identify what habits improve or lower your recovery levels.
