Researching the human heart and brain.

The HeartMath Institute (HMI) researches heart-brain communication and its relationship to managing stress, increasing coherence and deepening our connection to self and others. HMI’s scientists also explore the electrophysiology of intuition and how all things are interconnected.

Our Research is Transforming Lives

Since 1991, the HeartMath Institute has researched and developed reliable, scientifically validated tools and technologies that help people improve their emotional balance, health and performance. HMI also has conducted intriguing research on how the heart's magnetic field radiates outside the body and can affect other people.
