Ways to Increase Your HRV: A Comprehensive Guide for Optimal Health


Devices like the Apple Watch, Oura Ring, and Whoop Strap 4.0 can measure Heart Rate Variability (HRV), which reveals insights into our body’s autonomic nervous system activity. Monitoring HRV aids in identifying imbalances, offering the potential to detect early signs of health issues.

HRV, or heart rate variability, is a fancy way of describing the slight variations in the time between each heartbeat. Even though these changes are tiny, usually just milliseconds, they offer a valuable window into the health of your autonomic nervous system (ANS). Traditionally, healthcare has largely been reactive, focusing on treating diseases once they manifest. HRV, however, empowers a shift towards prevention by enabling us to track and understand our body’s subtle signals before imbalances manifest into full-blown health issues.

The ANS is a network of nerves that regulates involuntary body functions and is always working, whether we’re awake or not. constantly adjusting things like heart rate, breathing, digestion, and temperature. A healthy ANS maintains a dynamic balance between these two branches, constantly adapting to your environment and internal needs. This adaptability is where HRV comes in. A high HRV signifies a flexible and resilient ANS, while a low HRV indicates an imbalance.

Understanding Autonomic Nervous System (ANS)


The autonomic nervous system (ANS) is your body’s hidden controller, managing everything from heartbeat to digestion. It operates in two parts:

  • Sympathetic nervous system (SNS): Your “fight-or-flight” mode, activating during stress with increased heart rate, breathing, and blood flow.
  • Parasympathetic nervous system (PNS): Your “rest-and-digest” mode promotes relaxation with a slower heart rate, deeper breathing, and a focus on internal processes.

A healthy balance between these two branches is crucial. HRV, the slight changes in time between your heartbeats, shows this balance. High HRV means your ANS adapts smoothly, while low HRV indicates potential stress or imbalance.

Why is HRV Important?

A high HRV is generally associated with:

  • Improved cardiovascular health: Studies have shown that people with higher HRV are less likely to develop heart disease, stroke, and high blood pressure.
  • Enhanced stress resilience: A flexible ANS is better equipped to handle stress, helping you bounce back from challenges more quickly.
  • Better sleep: HRV dips naturally during deep sleep, so a higher HRV can indicate better sleep quality.
  • Increased athletic performance: Athletes with higher HRV tend to recover faster from training and perform better overall.
  • Improved mental well-being: Higher HRV has been linked to lower levels of anxiety and depression.

On the other hand, a low HRV can be a sign of:

  • Chronic stress: If your SNS is constantly on overdrive, your HRV will suffer.
  • Overtraining: Athletes who push themselves too hard can see their HRV drop.
  • Underlying health conditions: Certain medical conditions, such as heart disease, diabetes, and chronic obstructive pulmonary disease (COPD), can affect HRV.

Factors Affecting HRV

Exercise and HRV

Physical Activity:

  • Optimal Exercise Routines: Moderate-intensity aerobic exercise for 30 minutes most days of the week has been shown to improve HRV significantly. Examples include running, cycling, swimming, and brisk walking. High-intensity interval training (HIIT) can also be beneficial, but focus on recovery periods to avoid overtraining. Personalized plans incorporating fitness levels and preferences are key.
  • Mechanistic Impacts: Exercise enhances blood flow, mitochondrial function, and oxygen utilization, leading to better cardiovascular health and improved ANS flexibility. It also promotes stress reduction, further contributing to higher HRV.

Stress Management:

  • Effective Techniques: Chronic stress activates the SNS, lowering HRV. Combat this with regular practice of stress-reduction techniques like meditation, deep breathing, yoga, and mindfulness. Biofeedback can also be helpful in developing awareness of your ANS activity and learning to control it.
  • Lifestyle Adjustments: Identify and address your personal stress triggers, whether it’s work, relationships, or financial concerns. Prioritize time for relaxation and hobbies you enjoy. Building a solid support system and practicing good communication skills can also help manage stress effectively.

Quality Sleep:

  • Sleep Hygiene Tips: Poor sleep disrupts the natural rhythm of the ANS, hindering HRV. Aim for 7-8 hours of quality sleep each night by establishing a regular sleep schedule, creating a relaxing bedtime routine, and maintaining a cool, dark, and quiet sleep environment. Avoid caffeine and alcohol before bed, and limit screen time in the evening.
  • Deep Sleep Importance: During deep sleep, the PNS dominates, promoting HRV restoration. Prioritizing activities that enhance deep sleep, like regular exercise and stress management, can significantly impact your HRV.


  • HRV-Boosting Foods: Certain dietary choices can support ANS balance and improve HRV. Omega-3 fatty acids found in fatty fish, flaxseeds, and walnuts have anti-inflammatory effects and positively influence heart health. Magnesium, abundant in leafy greens, nuts, and whole grains, promotes relaxation and stress reduction. Adaptogenic herbs like Ashwagandha and Rhodiola have been shown to support the body’s response to stress, potentially impacting HRV.
  • Overall Dietary Patterns: Maintain a balanced diet rich in fruits, vegetables, whole grains, and lean protein while limiting processed foods, sugary drinks, and unhealthy fats. This supports overall health and provides essential nutrients for optimal ANS function.

Techniques for Increasing HRV

Deep Breathing Exercises

  • Simple yet Effective: Deep, slow breaths activate the vagus nerve, the main component of the PNS, promoting relaxation and boosting HRV. Explore techniques like belly breathing, 4-7-8 breathing, and alternate nostril breathing. Integrate these practices into your daily routine, starting with short sessions and gradually building duration.
  • Harnessing Technology: Biofeedback apps and devices can provide real-time feedback on your breath patterns and HRV, guiding you towards optimal breathing rhythms for maximum impact.
