The Healing Power of Magnets
Magnets have been used for their healing properties since ancient times, and now a new study has found that they can reduce swelling when applied immediately after an inflammatory injury.
In their initial study, researchers from the University of Virginia set out to investigate the effect of magnetic therapy on microcirculation, which is blood flow through tiny blood vessels.
They placed magnets of 70 milliTesla (mT) field strength, which is about 10 times the strength of the common refrigerator magnet, near rats’ blood vessels and found that they dilated constricted blood vessels, and constricted vessels that were dilated. The results suggested that the magnetic filed could relax blood vessels and increase blood flow.
In the more recent study, the researchers used magnets on rats’ paws that had been treated with inflammatory agents to simulate tissue injury. The magnets significantly reduced swelling in the rats’ paws by up to 50 percent when applied immediately after the injury.
Dilation of blood vessels is a major cause of swelling, and it’s thought that the magnets worked by limiting blood flow.
Muscle bruising and joint sprains are the most common injuries worldwide, and since injuries that don’t swell heal faster, the magnet therapy could have widespread applications.
The researchers envisioned using magnets in place of ice packs and compression to treat injuries in high school, college, and professional sports teams, as well as among retirement communities.

Dr. Mercola's Comments:
Magnetic therapy is a $5-billion market worldwide, and it is no surprise that in the United States the U.S. Food and Drug Administration makes it illegal to market magnets to treat significant conditions like HIV, asthma, or arthritis.
Do be aware, however, that it requires certain strengths of magnets to promote healing in the different areas of your body.
So if you’re looking to try this out yourself, it will take some work for you to do the research and find the correct strength and type of magnet for the specific condition you’re looking to heal.
I have actually been intrigued with magnet therapy for some time, as it seems promising and generally has very few side effects. And while magnets do not treat the underlying cause of any problem, they are far less dangerous than using drugs or surgery.
In addition to reducing swelling, magnets have been found to help with:
Age-related mental decline
There are countless products available, from magnetic bracelets and ankle straps to shoe insoles and mattresses, and it is really a buyer beware environment to make sure you are getting a quality product. Many commercial products do NOT have the proper field strength to be very effective.
Since I do not sell magnets, however, it is perfectly legal for me to explain to you how this process works.
Magnet therapy uses “static” magnets, which are called static because the resulting magnetic field is unchanging. (Please do not confuse these with electromagnets, which produce magnetic fields when an electric current is applied and really shouldn’t be used on your own.)
To use static magnets for pain relief, you must find a magnet of sufficient strength to provide a benefit. You can test this out yourself by placing the magnet next to a piece of clothing or sock, then placing a paper clip on the other side. If the magnet is not strong enough to hold the paper clip through your sock, then it will not penetrate your body either.
Alternatively, you should check out the strength of the magnet before you buy it. They are typically measured in units called gauss (G). Simple refrigerator magnets range from 35 to 200 G, but the magnets that may treat your pain range from 300 to 5,000 G. Some practitioners start with a lower gauss and gradually move up to a more intense level as necessary.
Magnet polarity is also important, as each magnet has two sides, negative and positive. The negative end, or north pole, generally has a cooling, sedating effect that is useful for relieving pain and inflammation.
The positive end, or the south pole, has the opposite effect and is stimulating, even to bacteria and viruses. So the positive end of the magnet needs to be used cautiously as it could actually promote disease and increase pain if it is used incorrectly. Because of this, the positive end of a magnet is typically used VERY carefully for conditions such as numbness, weak muscles, paralysis and scarring.
Most therapeutic magnets have their polarity marked, but to be sure you can check it using a magnetometer.
Once you have gauged the magnet’s polarity, you can place the proper side directly onto your skin and secure it in place with an elastic bandage. You will need to experiment with how long it should be kept on. Some conditions respond relatively quickly, while others can take much longer.
While on the topic of magnetic therapy, I can state that for the last six months I have been sleeping on a magnetic bed, which seems to have helped certain health challenges I was having.
I will review this more in future issues but let me make it very clear that this is NOT a bipolar magnetic bed that I was using. Bipolar magnets are thought to direct the potentially dangerous positive magnetic energy into your body, and I would caution all to avoid bipolar beds as I am convinced that they will actually increase your risk of cancer. This has been reported by a number of highly respectable clinicians in this field.
I was sleeping on a unipolar magnetic mattress pad, which more closely approximate the earth’s magnetic field and I believe is the far wiser choice.
Energy treatments like magnetic therapy are likely to gain even more steam in coming years, but remember that even a safe, alternative treatment like this will not remove the root cause of your pain or disease. However, when combined with my 10-step program for optimal health, magnetic therapy could be a safe, inexpensive addition.
