How does magnetic therapy work? ( The Magnetic Knee Brace )

( The Magnetic Knee Brace )

How does magnetic therapy work? This is very commonly asked question by many people who looking for alternative medical treatment.

All physical and mental functions are controlled by electromagnetic fields produced by the movement of electro-chemicals (ions) within the body. When an injury occurs and tissue is damaged, positively charged ions move to the affected area, triggering pain and causing inflammation.

In order for pain and inflammation to be relieved and healing to take place, the electromagnetic fields at the injury site must be restored to their normal balance.

The application of a magnetic field to an injured area helps restore the electromagnetic fields back to normal levels. The magnetic field relaxes capillary walls, as well as surrounding muscle and connective tissues, allowing for increased blood flow. More oxygen and nutrients are transferred to the injury site, while inflammatory-related toxins are removed. The overall process restores the normal electromagnetic balance of the area, relieving pain and inflammation, and promoting accelerated healing.

In next post, I will explain what are the factors determine the effectiveness of magnetic therapy products.

Type of Magnet used in therapy ( The Magnetic Knee Brace )

( The Magnetic Knee Brace )

Before we go further on magnetic therapy, let me introduce some common type of healing magnet that works for magnetic therapy;

1) Flexible Magnetic Rubber

Flexible magnetic rubber is made by consolidating Strontium or Barium ferrite powder with a polymer rubber matrix. This magnetic combination is formed into flexible magnetic rubber sheets or strips by extrusion or calendering, in some cases with self-adhesive backing. The rubber-based characteristics make the magnet for very flexible & bendable as well as resistant to water moisture and odor. The final magnetic rubber product has good resistance to demagnetization and reasonable resistance to chemical agents, and average temperature stability. It commonly formed in sheets or strips and used for magnetic therapy in shoe insoles.

2) Hematite Magnet
Hematite (AE) or haematite (BE) (sometimes miss-spelled as hemitite) is the mineral form of Iron (III) oxide, (Fe2O3), one of several iron oxides, formed from Magnetite. Magnetite is the most magnetic of all the naturally occurring minerals on Earth, and these magnetic properties led to its use as an early form of magnetic compass. Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control oxygen fugacity. Hematite also has the same crystal structure as ilmenite and corundum. Hematite is one of the most naturally occurring earth magnets with very special magnetic properties. Beaded magnetic hematite is very commonly used as bead magnets in high quality jewelry where bead strands are used to create beaded hematite bracelets, beaded hematite necklaces, or beaded hematite belts

3) Ceramic Magnet
Ceramic magnets are most commonly used in body wraps, knee brace pads and cushions. Ceramic magnets are manufactured by chemicaly combining a mixture of iron oxide and strontium ferrite to produce a metallic oxide. A multiple stage milling operation reduces the calcined material to a small particle size; this finely milled water borne powder is then compacted in the presence of a magnetic alignment field to a "green" state. These compacted parts, which approximate the finished geometry, are then sintered at high temperatures to achieve the final fusion of the individual particles. Parts which have been produced in this manner are anisotropic and will exhibit a preferred direction of orientation when magnetized. Final shaping of this material is accomplished by grinding with diamond abrasives. Normally, ceramic magnets will not only be ground on the pole faces; all remaining surfaces will exhibit as sintered tolerances and physical characteristics

Other than mentioned above, there are other type of magnet that commonly used for magnetic jewellry. They are Neodymium Magnets and Samarium Cobalt Magnets.

History of Magnetic Therapy ( The Magnetic Knee Brace )

( The Magnetic Knee Brace )

Magnetic energy is the strongest natural force in the universe and the power of magnets is one of the most basic powers of nature. Magnetic therapy has been in use for many thousands of years and it is still just as effective as it was when it was in use by ancient civilizations, such as the Ancient Greeks and Romans. This form of therapy has become more popular in recent years due to people's movement towards alternative medicine. This type of therapy is possibly more effective than it was previously since there have been many developments in the field since it was originally discovered.

Ancient Egyptians used loadstones to prolong life and improve health. It is said that Cleopatra wore a polished lodestone on her third eye, in the belief that it helped maintain her youth and beauty.

In more recent times, Paracelsus (1493-1541) considered to be the father of modern medicine, believed that the "life force' of the body was most influenced by the force found in magnets.

In Europe, Russia, China, Japan and many other countries, convinced of the benefits, millions of people continue to use magnet therapy. Today, we are experiencing an exciting revival of this ancient therapy. Resulting from the impact of more and more clinical studies and anecdotal evidence, 120 million people worldwide spend over $1.5 billion globally on the therapeutic benefits of magnets.
