Neurofeedback – Promising non-pharmaceutical intervention strategies for anxiety and depression!

Many people that I connect with express a desire to try other approaches to address symptoms of anxiety and depression before turning to medications, especially when it is their children that are suffering from such symptoms, as all prescription medications come with undesired side-effects.  As a psychotherapist and yoga teacher, I share the research with them that shows the effectiveness of integrating these two (yoga and talk therapy) healing arts to support the shift in focus toward health promotion for those who prefer to take a more natural, holistic approach to healing. Now I am excited to share recent research that demonstrates combining neurofeedback with heart rate variability training (e.g., deep slow abdominal yogic breathing) provides another viable non-pharmaceutical approach to address the symptoms of anxiety and depression.  And the research showed a reduction in symptoms for both children and adults!

Neurofeedback is not new and is a form of biofeedback, where instruments are attached to the body to provide information to the individual on the functioning of their body.  Biofeedback, including neurofeedback, as a field of study has been growing since the 1960s.  Neurofeedback (or EEG biofeedback) is the form of biofeedback that enables people to change the brain’s electrical activity.  An EEG (electroencephalography) is the device that captures the real-time brain wave activity so it can be displayed and assessed for any unhealthy patterns that might be contributing to symptoms, such as anxiety and depression.  Being able to offer a way to change unhealthy brain wave patterns through neurofeedback is of special interest to those of us working with clients to relieve such distressing symptoms because the brain is a central contributor to the emotions, physical symptoms, thoughts and behaviors that define many problems for which people reach out for support.

Yoga and it’s slow, controlled deep abdominal breathing is also not new.  What is new is the research that is showing how this yogic breathing impacts heart rate variability (HRV).  HRV has been shown to be linked with an increase in cardiovascular disease, specifically when the variability is low.  (Please refer to last month’s Reflection to learn more about HRV.)  Stress and anxiety increases the activity of the sympathetic nervous system, the system responsible for the flight-fight response in the body, leading to increases in heart rate and a lowering of heart rate variability. On the other hand, activation of the parasympathetic nervous system, the system responsible for the rest-digest response in the body, has been shown to decrease heart rate and increase heart rate variability, specifically through the stimulation of the vagus (Cranial X) nerve that controls the heart, lung and digestion.  It is the controlled breathing found in a regular yoga practice that stimulates the vagus nerve, bringing balance to the activity of the sympathetic nervous system activity.

Even more recent research has brought these two healing modalities together to assess the impact of stimulating both the brain with neurofeedback and the vagus nerve with deep abdominal breathing on symptoms of anxiety and depressing in both children and adults.  The results showed evidence that such training may provide an effective, non-pharmaceutical approach to reducing such symptoms, with some additional benefits such as improving blood pressure!

Heart Rate Variability, Stress Reactivity, and Diaphragmatic Breathing – How Yoga’s Basic 3-part Breath Practice Supports Body-Mind Health

One of the designations for the month of May is National Physical Fitness and Sports Month with the social media message of #MoveInMay.  So in support of this awareness effort, I would like to share the benefits of learning how to move your diaphragm to support your body-mind fitness!  Yes, that large skeletal muscle that divides our chest cavity from our abdominal cavity.  Did you know that the diaphragm is the primary muscle responsible for our ability to breath?

When I attended my first yoga class, I struggled with the instruction to allow my belly to expand on the inhale and to pull my belly button in on the exhale.  This was due to several societal messages that informed me that I needed to hold my belly in to look thinner and to hold in my powerful emotions as it was not acceptable (or safe) to reveal such feelings openly.  I had become what is referred to as a “reverse breather” where I held my belly in on the inhale and let it soften on the exhale.  Reverse breathing keeps the diaphragm from participating in the natural breath process, slowly starving the body of the oxygen it needs to function optimally.

When we get stressed navigating overwhelming situations, our bodies naturally react by pulling and holding the belly in, while our minds support the stuffing of our emotions down deep in the well of the body.  So for most of us who have suffered some adverse childhood event or events that traumatized our bodies and minds, allowing our breath to release the tight grip in our bellies is scary!  So reconnecting to this powerful muscle might be a slow process for many and yet, the research is showing that the effort is well worth the reward of improving our overall body-mind-spirit health.

A new measure of our health status, known as heart rate variability (HRV), is being researched as a marker for overall body-mind health identified through imbalances in our autonomic nervous system (ANS), between the sympathetic (flight/fight) and parasympathetic (rest/digest) branches, as reflected by the variation in time between heart beats.  When the variability is low, your overall health is reduced and we experience life as more stressful.  When there is greater variability, your overall health is increased and your ability to navigate stress is improved.  We may not have any conscious control over our ANS and the beat of our hearts; however, this does not mean that we have no way to impact our HRV to improve our overall health and well-being.

Recent research out of the University of Pennsylvania showed that learning to re-engage our diaphragm in our breath process has a direct, positive impact on HRV.  The research studied indices of physiological stress reactivity in varsity athletes before and after introducing a task that created cognitive stress.  Slow diaphragmatic breathing was shown to significantly increase HRV, while also reflecting a trend toward greater relaxation.  So if we are not able to eliminate stress in our lives, we now know we can simply look to one of our most basic processes of life – respiration – for relief.  And with that inner resource to relieve the external stressors of life, we can improve our health – body, mind, and spirit!
