Here is a nice overview, looking at the Magnesphere by Magneceutical Health.
The precise mechanism of operation can be explained by well-accepted principles of Quantum physics and biology, and is comprised of four basic elements:
1. Nuclear Magnetic Resonance: The basic physics principle by which a magnetic resonance imaging (MRI) device applies an external magnetic field to alter molecular or atomic targets in the body to achieve its results. The MRI device alters the molecules in the body with a very powerful magnet, in such a dramatic manner as to be able to obtain an image. In contrast, the Magnesphere™ device utilizes the same principle, albeit at targeted field strengths of a much lower (physiologic) level.
2. Chronic Stress: Adversely affects disease states and chronic conditions of many types, leading to an exacerbation of symptoms (typically stiffness, pain, inflammation, energy level, and sleep)
3. Stimulation of the Vagus Nerve with precise, physiologic magnetic fields produces a balancing effect on the Autonomic Nervous System (ANS) and its two branches: Sympathetic (“fight or flight”) and Parasympathetic (“rest and digest”). See the image below for a diagram of showing the importance of the Autonomic Nervous System.
4. By measuring the change in the balance of the ANS, using the biomarker Heart Rate Variability (HRV), we are able to determine which magnetic field(s) are best suited to “enhance feelings of relaxation” and help improve symptoms that have been exacerbated by Chronic Stress.
