What Magnetic Fields Do to Your Brain and Body

(Credit: pippeeContributor/Shutterstock)

There’s no escaping magnetic fields—they’re all around us. For starters, the Earth itself is like a giant magnet. A spinning ball of liquid iron in our planet’s core generates the vast magnetic field that moves our compass needles around and directs the internal compasses of migrating birds, bats, and other animals. On top of that, ever-industrious humans have produced artificial magnetic fields with power lines, transport systems, electrical appliances, and medical equipment.

We may not be able to see, hear, feel, or taste the magnetic fields that surround us, but some may wonder whether they can still exert effects on our bodies and brains. This question becomes more pertinent, and the answers more tantalizing, as the strength of the magnetic field in question gets cranked up.

Everyday Exposure

A magnetic field arises whenever a charged particle, like an electron or proton, moves around. Since the electric currents running through blenders, hairdryers, and wires in the walls of our homes consist of flowing electrons, they all generate magnetic fields. Through these sources, the average person is exposed to magnetic fields reaching 0.1 microtesla in strength on a daily basis. By comparison, the Earth’s magnetic field, which we are always exposed to (as long as we remain on the planet’s surface), is about 500 times stronger. That means the magnetic force penetrating your body as you lounge around your home or spend a day at the office is decidedly insignificant.

From time to time, a scientific study finds a link between living near high-voltage power lines and illness. Heightened risk of childhood leukemia is the most commonly cited potential health consequence, but whether or not the risk is real has been hard to pin down. One glaring issue is that scientists have yet to figure out the mechanism by which such weak magnetic fields—which are still in the microtesla range for homes next to power lines—could adversely affect the human body. In 2010, the International Commission on Non-Ionizing Radiation Protection concluded that the evidence that living near power lines increases the risk of the deadly blood cancer “is too weak to form the basis for exposure guidelines.”

What’s the Threshold?

Meanwhile, a team of scientists at the Utilities Threshold Initiative Consortium (UTIC) has been busy working to figure out the threshold at which the human body shows a physiological response to a magnetic field. According to Alexandre Legros, a medical biophysicist at the Lawson Health Research Institute and Western University in London, Ontario and a UTIC scientist, the smallest magnetic field that has reliably been shown to trigger a response in humans is around 10,000 to 20,000 microtesla. But crucially, to produce the effect, the field cannot be static like Earth’s magnetic field; rather, it must change directions over time. When these strong, direction-shifting magnetic fields get directed at a human, small electrical currents begin to pulse through the body. Above that threshold, the currents can stimulate super-sensitive cells in the retina, known as graded potential neurons, giving the illusion of a white light flickering even when the affected person is in darkness; these visual manifestations are known as magnetophosphenes.

The 10,000-microtesla threshold is well above the strength of any magnetic field encountered in everyday life. So in what situations might magnetophosphenes occur?

Medical Magnets

“There’s only one circumstance in which you may perceive magnetophosphenes,” says Legros: “If you’re in an MRI [magnetic resonance imaging] machine and moving your head fast.” An MRI scanner is essentially a big magnet that produces a powerful magnetic field of around 3 tesla (or 3 million microtesla) — millions of times larger than the fields we’re normally exposed to. But because it’s a static magnetic field, MRI scanners don’t exert any noticeable effect on the body. That would change, however, if the patient inside the scanner were to rapidly move his or her head back and forth. “Moving quickly induces a time-varying field, so by doing that you are inducing currents in different structures of your brain,” says Legros. Those currents may lead to nausea, loss of balance, a metallic taste in your mouth, or in some cases, magnetophosphenes.

On par with the magnetic field of an MRI is the one produced by a medical procedure known as transcranial magnetic stimulation (TMS). But unlike MRI, which makes detailed pictures of the inside of the body, the purpose of TMS is to stimulate the brain. That task requires an electric current, which is why TMS relies on a magnetic pulse rather than a static magnetic field. When this pulse is delivered via an electromagnetic coil placed against the scalp, the resulting current jolts a particular part of the brain with the aim of treating neurological diseases like depression.

Out-of-this-World Magnetic Fields

The magnetic fields associated with MRI and TMS are the strongest that a human might realistically be exposed to. Still, they are “hilariously puny” compared to those found beyond our planet, says Paul Sutter, an astrophysicist at Ohio State University and chief scientist at the COSI Science Center in Columbus, Ohio. At the extreme lies the aptly-named magnetar, which is a rare type of neutron star with a magnetic field one thousand trillion times stronger than Earth’s.

If any human ever got close to a magnetar, they would quickly find themselves in dire straits. “Strong magnetic fields can start to do surprising things,” says Sutter. At the atomic level, the strong magnetic field would move all of the positive charges in your body in one direction and the negative charges the other way, he explains; spherical atoms would stretch out into ellipses and soon they would start to resemble thin pencils. That drastic change in shape would interfere with basic chemistry, causing the normal forces and interactions between atoms and molecules in the body to break down. “The first thing you would notice is your entire nervous system, which is based on electrical charges moving throughout your body, is going to stop working,” says Sutter. “And then you basically dissolve.”

Sutter guarantees that our local neighborhood — which he defines as a radius of a few hundred light-years around Earth — has been surveyed and certified magnetar-free. None of these exotic objects are approaching us, and none of the massive stars nearby are likely to turn into magnetars when they die. The nearest magnetar is a safe distance of tens of thousands of light-years away. So, at least for the time being, we can rest easy and take comfort in our planet’s own meager magnetic field.

Yet Another Study Says Vitamin Supplements Are Worthless

(Credit: Thunderstock/Shutterstock)

Vitamin — the first four letters come from the Latin word for “life.” To sustain that, we need these organic compounds in small amounts, but it seems their purpose ends there.

New research reaffirms the counterintuitive notion that vitamin and mineral supplements aren’t the magical panacea we’ve been led to believe. It’s something that researchers have been finding for years, and a meta-analysis, summarizing the findings of 179 individual studies, published on Monday in the Journal of the American College of Cardiology found that most common vitamins provide precisely zero benefit to those taking them.

Non-vital Vitamins

Specifically, the study concluded that multivitamins, as well as calcium, and vitamins C and D are essentially powerless. They do no harm, but they might as well be placebos. These findings run contrary to popular wisdom, which instructs us to load up on supplements to reduce the risk of heart disease, cancer and premature death.

This isn’t the first time science has refuted vitamin worship. In 2013 a series of studies in the Annals of Internal Medicine, collectively including hundreds of thousands of participants, concurred that vitamins do not lead to any boost in health. In fact, the studies found that beta-carotene, vitamin E and possibly high doses of vitamin A actually slightly increase mortality.

The only supplement that may live up to its reputation, according to the new study, is folic acid. This, with or without vitamin B, may prevent cardiovascular disease and stroke.

The tradition of using vitamins and minerals for nutrient deficiencies dates back to 1747, when the British naval surgeon James Lind treated scurvy with citrus fruit, rich in vitamin C. Physicians routinely make such prescriptions, though usually only in cases where the patient has a demonstrated deficiency of a particular vitamin or nutrient.

Supplement Crazy

In recent years, though, we’ve come to view supplements as the gateway to general health and longevity. A Gallup poll in 2013 showed that 50 percent of Americans regularly take vitamins or multivitamins.

On the flip side, a comparison of Gallup polls in 1975 and 2016 reveals plunging public trust in the mainstream American medical system. This phenomenon may have contributed to the ascent of “natural” vitamin and mineral supplements.

But it probably also stems from rampant marketing and advertising. Thanks to the Dietary Supplement Health and Education Act of 1994, manufacturers don’t have to prove the to the Food and Drug Administration that their supplements work. They can claim their products work, though, as long as they keep it vague (“strengthens the body”) and don’t profess to truly treat anything.

Call it a healthcare failure, call it a marketing miracle. Either way, call a doctor before you pop another vitamin. Odds are they’ll tell you to stick to fruits and veggies.

Morgellons and Dope (Crack)

Even though this person in this video blog needs help with her drug addiction she shares her true story of being infected with morgellons. Everyone has their own way in dealing with this horrible disease. If you google Morgellons or resistant scabies mites you will come across forums of people questioning if some narcotic drugs could possibly get rid of these things. It’s not uncommon to hear individuals who gets high and complains about feeling bugs crawling all over them, biting them, etc. In reality in many cases it is true. Because of these narcotic drugs poisoning the system it drives them out of the body. Just as the same as if taking anti-parasitic drugs such as ivermectin.

Morgellons disease is a poorly understood condition characterized by small fibers, particles and bugs emerging from the skin. People with this condition often report feeling as if something is crawling on or stinging/ biting their skin.

In no way do we endorse or suggest in using any illegal substance to deal or attempt to get rid of morgellons or resistant scabies mites.
