This is how our heart looks when we are happy, feeling the uplifting emotions of joy, gratefulness, love, compassion, and appreciation. While we want this variability in our heart rate we want this variability to be in a pattern - when you plot your heart rate over time the overall shape of the waveform should be like a smooth harmonious set of waves. Low heart rate variability is an indicator of low vagal tone and will be associated with the same diseases heart disease, blood pressure, diabetes, and inflammatory diseases in general. If the heart does not slow down on the exhale it could be triggered by an old traumatic event that is still effecting us, or low level daily stress such as from a job or unhealthy relationship. If your heart is beating like a metronome this is a sign your stress response is in overdrive, if not addressed this can lead toward the development of diseases in the body. As you exhale the chest compresses inward putting pressure on the heart which speeds up blood flow, so your vagus nerve signals your heart to slow down.Ī healthy heart rate variability means your autonomic nervous system is in balance ~ meaning you can quickly react when necessary to a stressor and then let it go and recover back to homeostasis where healing, digestion, and regeneration can carry on.When you inhale your chest expands which allow more room for blood to rush into the heart, so your body says to your nervous system “hey pick up your heart rate”.This allows the heart to pump in more blood on the inhale and less blood out on the exhale which better oxygenates the blood. The heart has two main nerves connected to it, the accelerans nerve and the vagus nerve - the accelerans nerve is what stimulates the SNS, and the vagus nerve is what stimulates the PNS which puts a brake on the SNS. When we inhale it signals the sympathetic system to increase our heart rate and when we exhale it signals the vagus nerve to slow down the heart rate. This is a sign of healthy vagal tone because it is slowing down the stress response appropriately. There is some variability in our heart’s beat to beat difference a healthy heart rate variability is when our heart rate increases on our inhales and decreases on our exhales. Resonance breathing, Coherence, & Heart Rate Variability aka HRVĪ heart rate that increases on your inhales and decreases on your exhales.Ī heart rate of 60 or 70 BPM has a beat to beat difference in a healthy person - your heart is not like a metronome just ticking away at a steady beat (unless you are stressed).
