	Cardiac coherence is a form of breathing exercise which alternates approximately 5 second-long in and out breaths. It tends to create a synchronization of heart and breath rythms, maximizing heart-rate variability. According to Nashiro et al. (2025),<blockquote>slow breathing around the baroreflex frequency (6 breath per minute, 0.1 Hz, or 10 s/breath) generally activates parasympathetic vagus nerve activity, suppresses sympathetic/noradrenergic activity, and increases heart rate oscillations. Repeated practice of baroreflex-frequency breathing to increase heart rate oscillations promotes a number of health benefits, including long-term emotional health and positive effects on cardiovascular diseases.<ref name=":0">Nashiro, K., Cahn, B.

It tends to create a synchronization of heart and breath rythms, maximizing heart-rate variability. Cardiac coherence tends to be milder in its effects than other forms of breathing exercise, rarely inducing intense modulations of lived-experience, and is perhaps not an [[Synthesis:Emergent Modalities\|emergent modality]] per se, but it has a variety of health benefits. According to Nashiro et al. (2025),<blockquote>slow breathing around the baroreflex frequency (6 breath per minute, 0.1 Hz, or 10 s/breath) generally activates parasympathetic vagus nerve activity, suppresses sympathetic/noradrenergic activity, and increases heart rate oscillations.
