**7. The HeartMath Website**

The HeartMath website can be found at https://www.hearthmath.org/, accessed on 4 April 2021. The website and annual report provide further practical healthcare information. For example, it lists programs, including Add Heart and Children's Heart Smarts and the 100,000 Coherent Kids Initiative, active in 93 countries. Since its inception, the HeartMath Institute has facilitated links with other health, educational, and research institutions. These established linkages are combined with the interdisciplinary originality and operational autonomy to lead to ground-breaking research in interdisciplinary fields such as biofield physiology and vibroengineering, which have impressed with their robust, scientific grounding [36].
