Does HeartMath Measure Brain Waves (EEG)?

Overview HeartMath technology focuses on the heart's rhythm to improve physiological coherence. Customers often ask if the sensors also track brain activity due to our research on heart-brain communication.

Capabilities

  • Measures: Heart Rate (BPM) and Heart Rate Variability (HRV).

  • Calculates: Coherence (the order/stability of the heart rhythm pattern). 

  • Sensor Type: PPG (Photoplethysmography) – an optical sensor that detects blood flow volume in the earlobe.

Limitations

  • Does NOT Measure: Brain waves (Alpha, Beta, Theta, Delta, etc.).

  • No EEG: The sensors are not Electroencephalograms (EEG) and do not attach to the scalp.

The Heart-Brain Link While the device monitors the heart, the practice influences the brain. A coherent heart rhythm facilitates cortical function (clearer thinking), while an incoherent rhythm (stress) inhibits it.
