The Science Behind Halcytone
Grounded in decades of research on heart rate variability, breathwork, and neurophysiology.
Research Foundations
Halcytone builds on proven findings in heart rate variability (HRV), biofeedback, and structured breathwork. Studies show that paced breathing at an individual's resonant frequency can increase HRV and promote autonomic balance, creating measurable calm.
Clinical Evidence
- Resonant breathing biofeedback improves baroreflex function and asthma control[1]
- Greater HRV is linked to emotional regulation and resilience[2]
- Paced respiration induces synchronized HRV oscillations[3]
- Yogic breathing practices reduce symptoms of stress and depression[4]
How Biofeedback Works
Real-time sensory feedback nudges your breathing toward patterns that activate the parasympathetic nervous system. This lowers heart rate, steadies the mind, and trains your body to access calm on demand.
Brainwave Entrainment
By pairing breath-guided cues with audio rhythms, Halcytone encourages brainwave patterns associated with focus and relaxation. This entrainment supports deeper states of presence and recovery.
