Heart Rate Variability (HRV) Biofeedback Used In Virtual Reality High Performance Training

Competitive athletes should not only practice their sport to improve performance; perhaps they should also practice heart rate variability (HRV). Studies have shown that learning to increase heart rate variability through biofeedback can improve sport performance and help athletes cope with the stress of competition. A link to download the original study is included in […]

Hyperactive Autonomic Nervous System In Patients With Breast Cancer May Cause Fatigue And Aging

The persistent fatigue that plagues one out of every three breast cancer survivors may be caused by one part of the autonomic nervous system running in overdrive, while the other part fails to slow it down.  That imbalance of a natural system in the body appears linked to the tiredness and exhaustion that can burden […]

The Six Bridges, Body I/O, and Conscious Influence Over Autonomic Function

In 2004, I introduced the concept of the “bridge.” Since that time, this author and others have been working with bridges to understand their significance in facilitating conscious influence of the body/mind. Humans, in fact vertebrate life in general, interact with the environment via fifteen bodily functions or “interfaces”. These input/output functions include the eyes, […]

(In)Accurate Intuition Is Related To Physiological Changes In The Body

When faced with decisions, we often follow our intuition – our self-described “gut feelings” – without understanding why. Our ability to make hunch decisions varies considerably: Intuition can either be a useful ally or it can lead to costly and dangerous mistakes. A new study published in Psychological Science, a journal of the Association for […]

COHERENCE – The Big Picture

In physics, “coherence” is a complex measure of wave phenomena. Specifically, its a measure of the correlation between all of the physical properties of waves, e.g., amplitude, phase, and frequency. If two perfectly “coherent” waves collide, waves that are exact in every respect, they will negate each other perfectly, this “stationary interference” being proof positive […]
