How magnets affect your body?
Indispensable information about how your body will react to magnets.
Plus how to ensure you use them to maximise your results.
Magnets are composed of metal alloys such as iron, nickel or
cobalt they will attract many different types of metallic particles. The blood
contains iron and when therapeutic magnets are placed on the skin the magnetic
field penetrates through the skin and into the surrounding tissues and blood
stream. The iron in the blood is attracted to the magnetic field, this causes
movement within the blood stream and the increased activity causes the blood
flow to improve.
The increase in blood flow is localised to the area where the
magnets are placed, unless the magnets are placed directly over a major artery
such as the radial artery (the wrist pulse point) or the carotid artery (the
pulse point in the neck). When magnets are placed over a major artery there is a
much larger perfusion of blood flow so the magnetic field is carried further
around the body.
When the body’s blood flow is increased oxygen, nutrients and
hormones are distributed to the organs and tissues much more effectively and
quickly. Your organs have a fresh rich supply of oxygen and nutrients to nourish
them. Plus the tissues also gain oxygen, healing nutrients and hormones
including endorphins, which are the body’s natural painkilling hormone. If you
have an injury or ailment which is supplied with regular fresh oxygen, nutrients
and endorphins then your injury or ailment will heal much faster and the pain
will be reduced by the body’s own painkilling hormones (endorphins).
What happens when I have inflammation?
The inflammatory reaction is one of the body’s oldest defence
mechanisms. When damage occurs the body’s automatic defence system starts the
inflammatory process within seconds. Blood flow is firstly increased at the
point of injury, the blood vessels widen to allow oxygen, clotting agents and
white blood cells to penetrate the damaged tissues. Over a period of hours the
concentration of white blood cells increases at the injury site (white blood
cells fight infection).
Individual cells are affected by the inflammatory process. Extra fluid migrates
from the blood vessels into the damaged cells; this begins the process of
disrupting the ionic balance of the cell. The chemical balance of the cell
changes and cellular degeneration begins. The presence of extra fluid, white
blood cells, increased blood flow with in the tissues causes the damaged area to
enlarge and swell, this is commonly known as oedema.
How magnets fight inflammation?
When therapeutic magnets are placed over an area of inflammation,
the magnetic field penetrates through the skin and deep into the tissues and
blood stream. Damaged cells will react to the presence of a magnetic field by
realigning their ions into the correct position. This begins the process of
eliminating the excess fluid from with in the cell. Cell damage will stop and
healing of the cells will begin over a period of days.
When inflammation in the body is alleviated, the damage caused by
the inflammatory process begins to be repaired by a fresh and rich supply of
oxygen and nutrients. Cells that have been disrupted and de-oxygenised begin to
heal and tissue regeneration starts. Excess fluid is eliminated from the body
and toxins are removed. The circulatory system returns to normal and the heart
does not have to work so hard to pump extra fluid around the body. Magnetic
fields will stabilise all of these processes and aid the body in its recovery.
Discover which strength magnets you need.
It is absolutely vital for any one who is currently using or
contemplating using magnetic therapy to thoroughly
understand how magnetic strength is measured and what is the appropriate
strength of magnet to use for healing
purposes. Magnets are perfectly safe and do not have adverse side effects so
users should not worry about overdosing on magnetic strength, however it is
possible to under dose on strength.
So how strong should a medical magnet be? A therapeutic magnet should be a
minimum of 800 gauss or 80m tesla to penetrate through the skin, into the
tissues and increase blood flow. Having said that an 800 gauss/ 80m tesla magnet
is by no means weak. It does have sufficient strength to stimulate blood flow
and reduce inflammation.
The stronger the magnet the deeper the penetration into the skin and the wider
magnetic field, so for more serious ailments and chronic, longstanding
conditions, stronger magnets are recommended. 1,500-2,000 gauss/150-200 m tesla
magnets are considered to be high strength. This strength will reduce the
symptoms of many chronic inflammatory complaints, for example tendonitis,
cruciate ligament injuries, arthritis( rheumatoid and osteo), spondylosis and
general joint wear and tear.
For extreme pain and very severe conditions super strength magnets are
advocated. These are magnets that have a gauss/m tesla rating of 3,000/300 or
above. Super strength magnets are rapidly gaining in popularity as they such a
deep level of penetration and create a very large magnetic field. Results are
more rapid with this strength of magnet. They are recommended for people who
suffer with multi location pain and all over body pain, for example
fibromyalgia, M.S., M.E. and severe arthritis.
Size is not as important as you might think
The size of a magnet is not relative to its strength. Many people believe that
the bigger the magnet the stronger it will be, this is not the case. Very high
strength magnets, for example, a 3,000 gauss/300 m tesla could be as small as
3mm in diameter. Similarly an 800 gauss/ 80 m tesla magnet could be quite large
(in therapeutic terms) and be the size of a 2 pence piece. The smaller of the 2
magnets is by far the stronger. The average size of a therapeutic magnet is
approximately 18mm in diameter. Healing magnets are small because they have to
be able to be placed as close to the point of injury as possible, if they wear
larger in size it would not be easy to attach the magnets over the pain point,
plus larger magnets are uncomfortable as they are heavy to wear and will “dig”
into the skin.
The size of the magnet does determine one important factor, the range of the
magnetic field. The larger the magnet the wider the spread of the magnetic
field. This means that the field will radiate outwards in a wide circle, however
it does not mean that the field will penetrate deep into the tissues. A small
magnet will not create such a wide spread magnetic field surrounding the magnet
but it will penetrate much deeper into the tissues. The general rule to remember
is: A weak large magnet will cover a large area on the skin but will only have a
shallow penetration depth into the skin. A strong small magnet will cover a
small area on the skin but will have a deep penetration depth into the skin. To
ensure that you have a wide magnetic field that also penetrates deep into the
tissues, choose a magnet that is over 2,000 gauss/260 m tesla and at least 8mm
If you want your magnets to work fast you must place them on the right area and
wear them for the correct length of time
As you move away from a magnet the magnetic force decreases. What this means is
when you place a magnet on any point of the body, the magnetic field is at its
strongest right at the point of contact with the magnet and the body. The
farther the magnet is from an area the weaker the magnetic field. For example if
you placed a 3,000/300 m tesla magnet in the wrist the magnetic force around the
wrist would be 3,000 gauss/300 m tesla.
The strength of the magnetic field 4 cm away from the magnet surface will be
1/16th of the strength at the surface i.e. 187.5 gauss/18.75 m tesla, the
strength at 8 cm would be 1/64th of the strength at the surface i.e. 46.88
gauss/ 4.68 m tesla an so the equation continues the farther the distance from
the magnets surface. This principal is known as the inverse square law. You do
not have to memorise this law to be able to use magnets effectively but it is
very important to understand that the further away a magnet is to the point of
injury the weaker the magnetic field will be, which is why magnets should always
be worn directly over (or as close to as possible) the point of injury.
Magnets should be worn or used until your symptoms have cleared. If you stop
using your magnetic therapy products before your symptoms have resolved, the inflammation
and pain associated with your injury may return very quickly. The best way to
use any magnetic device is to continue use for around 3-4 weeks after your
symptoms have disappeared. This will allow the magnetic field to ensure that all
of your symptoms have been resolved plus encourage new cell growth and healing
of soft tissues. There is no maximum length of exposure to magnets, you can
safely use magnets for as long as you like. Some people prefer to wear them
permanently as they do not want their symptoms to return. Once your symptoms are
alleviated and you stop using your magnets the benefits will remain for a period
of time. If your ailment is chronic and has no cure, for example arthritis, the
symptoms will eventually return. It is impossible to calculate how long this
will take as everybody has a slightly different experience, as a general rule
the more severe your condition the sooner the symptoms will return.
