Breathing is essential to life. The body self-regulates our breathing cycles subconsciously, with a standard respiration rate averaging between 18 and 20 breaths per minute. Stress, adrenaline, and other outside factors can drastically affect our regular respiration rate, sometimes even leading to hyperventilation under situations of extreme stress. Thankfully, we have <a href="https://thehumancondition.com/breathwork-science-types-benefits/">some control over our breathing rate</a>, and with the practice of coherent breathing, we can influence our body to calm itself down and get back to a more balanced and regular breathing cycle.

The SNS responds to perceived danger. It increases heart rate and blood pressure to prepare the body for the fight-or-flight response or causes the body to collapse in a freeze response.<a href="https://thehumancondition.com/polyvagal-theory-exercises-benefits-examples/" dir="ltr">2</a>,<a href="https://cptsdfoundation.org/2020/03/02/poly-what-understanding-polyvagal-theory/" dir="ltr">3</a>&nbsp;The PNS brings the body back to homeostasis by calming the body and lowering the heart rate and blood pressure.2,3&nbsp;Traumatic experiences can damage the nervous systems and cause conditions like&nbsp;<a href="https://thehumancondition.com/complex-posttraumatic-stress-disorder/" dir="ltr">complex posttraumatic stress disorder (C-PTSD)</a>&nbsp;and&nbsp;<a href="https://thehumancondition.com/anxiety-and-related-conditions/" dir="ltr">anxiety disorders</a>.2,3<h2>What Is Coherent Breathing?</h2>Coherent breathing is a technique in which a person intentionally controls their breathing rate to help relax and calm their body, regulate their heart rate, and remove themself from a fight-or-flight response or adrenaline spike. The primary goal of coherent breathing is to increase the length of each breath, in turn sending signals to your brain to slow down your heart rate. Coherent breathing may be incorporated into various exercises, like yoga, weightlifting, running, and other rigorous activities, to help control one’s heart rate. It may also be combined with relaxation techniques like&nbsp;<a href="https://thehumancondition.com/meditation-overview-research-effectiveness/" dir="ltr">meditation</a>, where focusing on one’s breathing cannot only help calm their heart rate but also help block out outside stimuli.According to Stephen Elliott, founder of the coherent breathing method, “Fundamentally, coherent breathing leads the breather to inhale and exhale synchronously at their resonant rate, in combination with conscious relaxation, to facilitate wave action in the body. Resonant&nbsp;coherent&nbsp;wave action depends on both breathing and relaxation.”<a href="https://coherentbreathing.org/" dir="ltr">4</a>&nbsp;According to Elliott, when breathing is coherent, it influences the heart rate variability (HRV) cycle, which tends to synchronize with the breath.5<h2>Background/History of Coherent Breathing</h2>Developed by Stephen Elliott, an engineer and scientist, in the early 2000s, coherent breathing initially focused on the “respiratory arterial pressure wave” and its relationship with HRV.4&nbsp;The goal is to consciously adjust your breathing cycle to about five breaths per minute instead of the normal higher rate of breaths per minute. This can help regulate the sympathetic and parasympathetic nervous responses, which regulate your heart rate via the atrioventricular node, commonly known as the heart’s pacemaker. It’s important to note that the technique focuses only on the timing of each breath, adjusting the duration and rhythm of the inhalation and exhalation cycles, and not necessarily on the volume of each breath. Your body will automatically adjust the volume of each breath as you focus on the timing. The slower and higher volume breaths signal to the brain that the body should be more relaxed, settling the sympathetic nervous system and shifting more toward parasympathetic control.<a href="https://vitalheartandvein.com/blog/breathing-techniques-lower-blood-pressure/" dir="ltr">6</a><h2>How To Do Coherent Breathing</h2>Although performing coherent breathing techniques is simple on the surface, it does require some thought and conscious effort to regulate your breathing properly and to breathe properly.The coherent breathing protocol involves the following guidelines:<a href="https://www.youtube.com/watch?v=p2rXctGxilU" dir="ltr">7</a><OL><LI>Breathing should occur at a rate of five breaths per minute.

Coherent breathing techniques are also used to help train individuals with dysfunctional breathing patterns or who have chronic shallow breathing to help fully utilize their diaphragm and break the habit of breathing from the chest rather than taking full deep breaths.<h2>The Effectiveness of Coherent Breathing</h2>Certain mental health conditions, such as major depressive disorder (MDD), are associated with low heart rate variability (HRV).<a href="https://doi.org/10.1016/j.mehy.2012.01.021" dir="ltr">8</a>,<a href="https://doi.org/10.1089/acm.2016.0140" dir="ltr">9</a>&nbsp;Slow-paced breathing practices have been suggested to improve mood and increase HRV.9,<a href="https://doi.org/10.1016/j.psc.2013.01.001" dir="ltr">10</a>&nbsp;In individuals with MDD, resonant breathing has been shown to increase HRV and enhance mood.9,<a href="https://doi.org/10.1007/s10484-006-9029-z" dir="ltr">11</a>&nbsp;Resonant breathing has been described as “coherent breathing with pursed lips resistive exhalation.”9&nbsp;Further studies have shown positive outcomes from using coherent breathing techniques and yoga in treating MDD by measuring certain neurotransmitter levels in the brain.<a href="https://doi.org/10.1089/acm.2019.0234" dir="ltr">12</a>Coherent breathing and other breathing techniques have also been shown to affect brain activity, specifically in the prefrontal cortex, insula, hippocampus, and amygdala.<a href="https://doi.org/10.1152/jn.00551.2017" dir="ltr">13</a>In a 2012 study of 37 undergraduate college students, participants were randomly assigned to a coherent breathing group, a meditation group, and a reading group as a control group.

Coherent breathing is a breathwork technique in which a person intentionally increases the length of each breath to help relax and calm their nervous system and heart rate.
