Discover the science-backed power of Heart Rate Variability (HRV) training.
Whether you’re seeking relief from anxiety, peak performance in sports, or advanced tools for your clinical practice, HRV is the key to unlocking physiological adaptability and emotional control.
What is Heart Rate Variability (HRV) Training?
Let’s start with it’s definition. What is Heart Rate Variability? The straightforward answer is: a measure of the beat-to-beat variations in heart rate. Elaborating a bit more:
HRV is a form of biofeedback training that involves using precise heart beat data, paired with a specific breath pattern to learn to sync your breath and your heart rate – there by optimizing your physiological health. A biofeedback device helps a client see when they have maximized this interaction by displaying data on a computer or phone screen. This feedback loop allows the client to optimize their nervous system’s balance between sympathetic and parasympathetic responses.
While the rhythmic beating of the heart at rest was once believed to be consistent and regular, we now know that the rhythm of a healthy heart under resting conditions is actually surprisingly irregular. HRV is an important indicator of both physiological resiliency and behavioral flexibility, reflecting an individual’s capacity to adapt effectively to stress and environmental demands. Little variation can be related to chronic pain, anxiety and depression as well as numerous other symptoms.
HRV Training uses an sensor to detect the variations in heart rate, and presents a display on a computer monitor. By controlling your breathing pattern and intentionally shifting to a positive emotion, such as appreciation, care, or compassion, your heart rhythms and breathing become synchronized and create a healthier emotional state.
This shift in heart rhythms creates a favorable cascade of neuronal, hormonal, and biochemical events that benefit the entire body. Blood pressure drops. Stress hormones plummet. The immune system pumps up. Anti-aging hormones increase. You gain clarity, calmness, and control.
Why is Heart Rate Variability (HRV) important?
Through evolution, our nervous systems have been programmed to protect us. Dating back to the caveman, those who had a stronger “fight or flight” response were more likely to survive in the primitive world. Over the centuries, this resulted in the human brain being programmed to have a strong “fight or flight” reflex. In the modern world we do not need to fight for our lives, but our nervous system does not know that, so it can become easily activated when there is perceived stress (such as giving a presentation before others, meeting new people, worrying if you think your child is in danger, etc.) This constant activation of our nervous system can manifest as anxiety, anger, and even physical symptoms. HRV has been shown…”to promote self-regulation of this fight or flight response by improving vagal tone.”

HRV was the primary measure used to determine the health of Russian Cosmonauts, as it could be measured while they were in space. There is now substantial support that HRV can improve a variety of disorders, as well as be used to enhance peak performance.
In determining the benfits of a clinical intervention, researchers consider 5 levels of efficacy, with levels 1-3 indicating support for clinical us. Distinctions between the levels are related to the rigor of research supporting the application double-blind studies with follow-ups are required for a level 1 rating.

Benefits of Heart Rate Variability Training
In today’s world, it is not uncommon that young children through adults to experience stress. As we know, stress is linked to illnesses like cancer, lung disease, suicide among many others.
By applying Heart Rate Variability Training to your routine you increase your chances of success to succeed by learning to regulate your own body during stressful situations such as a sports competition. Benefits, of course, extend well beyond sports into the occurances of day to day stressors from exams to interpersonal conflicts.
These are some of the benefits HRV can provide:
- Better personal health
- Development of emotional control
- Better performance at work
- Improved learning
- Improved stress management
- Decrease in sleep latency
- Decreased anxiety
- Lower blood pressure
Why is Heart Rate Variability (HRV) important?
Our psychologists are Board Certified in Heart Rate Variability (BCIA.org) and have been doing HRV training since 2000. We have evaluated and trained thousands of people using this form of biofeedback.
BCIA.org will list the certified providers in your area. If you have a medical condition, it is essential that your biofeedback trainer works in conjunction with your physician. Once you have spent a few sessions with your HRV trainer, you can begin to practice at home. Improved HRV can occur within a fraction of a minute even in people who have never previously been exposed to the technique. Using HRV on a daily basis is a simple, easy to implement way to improve your mental and physiological resilience.
Once you have been coached by a practitioner, there are several systems you can use to measure and practice HRV at home, including
EmWave by Heartmath – a PC/Mac program
Unyte – a PC/Mac program for HRV and meditation
Inner Balance – An app that interfaces with your PC
Optimal HRV – App
