[[Heart Rate Variability]] and [[Emotions MOC]] # How heart rate variability affects emotion regulation brain networks [Mara Mather](https://pubmed.ncbi.nlm.nih.gov/?term=Mather%20M%5BAuthor%5D) and  [Julian Thayer](https://pubmed.ncbi.nlm.nih.gov/?term=Thayer%20J%5BAuthor%5D) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5761738/ Paper - [[How heart rate variability affects emotion regulation brain networks.pdf]] --- Higher emotional well-being is correlated with higher HRV. However not sure if it's a cause or result - Having high heart rate variability (HRV) is associated with higher emotional well-being [1– 3], including being correlated with lower levels of worry and rumination [4], lower anxiety [5], and generally more regulated emotional responding [6]. Thus, individuals with higher HRV appear to be better at regulating their emotions. However, it is not clear from these correlational studies if HRV is simply an output measure of regulatory brain health, or whether it somehow increases prefrontal regulation effectiveness. Resonance Breathing increase Amplitude of Heart Rate Oscillations I think they are saying that HRV can be a cause for better emotional outcomes, through heart rate oscillations through breathing exercises.
