EMFs and Intracellular Calcium – Magnesium is nature’s calcium channel blocker

Electromagnetic fields, (EMFs) are the non-ionizing radiation that makes WiFi connections work and other devices like televisions and cellphones. The electronic details are beyond my field of experience and they are generally claimed to be harmless however research is being done on the health effects on people and other species. As more and more ‘hotspots’ become active and there is discussion of making entire regions WiFi spots the question of whether the radiation is truly harmless or not is important.

The research that has been performed suggests that the mode of action is on the ion channels in cell membranes called voltage-gated calcium channels (VGCCs). The EMF radiation seems to activate ion channels and allows the interior of the cell to fill with calcium which then can proceed to activate membrane breakdown and other actions within the cell. Oxidative stress can involve an excess of calcium within the interior of the cell which leads to other free radical chemicals – electrically active chemicals which antioxidant nutrients can help deactivate. See: (1)

Oxidation is a normal part of cell function as it is how glucose sugar energy is freed for use. Too many oxidative free radical chemicals also called, reactive oxygen species (ROS), can overpower the natural antioxidant chemical pathways and lead to increased cell damage and even cell death. (2, 3, 4)

Ion channels refer to chemicals that contain atoms that have a positive or negative charge which can be used to provide energy for chemical reactions. Ions in nature generally are found in pairs with a balance of positive and negative charges so the grouping is fairly stable. Calcium and magnesium both have ionic forms with a chemical charge of +2, which means they are missing two electrons. Sodium and potassium have ionic forms with a chemical charge of +1 – they are missing one electron each.

An ion is an atom or chemical that has more protons than electrons and carries a positive charge or has more electrons than protons and carries a negative charge, while a free radical specifically has at least one unpaired electron in its outer electron shell/valence which makes it very reactive but does not necessarily mean an electron is missing nor suggest a negative charge. Depending on their chemistry they may be able to receive or donate another electron and are very reactive, very active chemically, as the outer shell prefers to be stable chemically. The presence of an unpaired electron makes the free radical chemically encouraging other chemicals to give up or receive the unpaired electron even if the other chemical is more chemically stable. (7) The electrons in an atom are arranged around the inner ball of positively charged protons and neutrally charged neutrons in layers of electrons (valences) which prefer to be in groups of 2, 6 or 8 electrons, so a free radical with an outer layer with one electron might want to donate it while one with an outer shell with seven electrons might want to receive an extra electron.  Element valences are slightly different than what might be expected looking at the Table of Elements – here is a chart of the typical ion or free radical charges: (6)

Oxygen can carry an electrically negative charge of -2, meaning it can accept two additional electrons in its outer valence. And hydrogen can accept or donate an electron, +1 or -1, (6) which chemically can result in our most important molecule for life – water, H2O, formed from two atoms of hydrogen sharing their unpaired outer electron with one atom of oxygen which wants an additional two electrons. The slight preference for different electric charges gives the molecule of water a slight polarity, the oxygen part of the water molecule has a slight negative charge on average while the hydrogen parts of the molecule have slight positive charges. (8) A more thorough description of the chemical structure of the water molecule and its electrical charge distribution with illustrations is available here: (12).

Why is this important? Because our bodies are made up of at least 70% water and electromagnetic radiation does have effects on water (9) so a basic understanding of the chemistry can help understand the more complex issues of why having region wide areas of WiFi might affect health of humans and other animals, plants and possibly even microbial life. There is evidence that microbes can modify nearby DNA of other species via EMFs generated by the microbial DNA when both sets of DNA are in a watery dilution. (10, [1602 from ref 9]) This may increase infection or risk of cross contamination of infectious substances. We don’t know what we don’t know. The research may simply confirm the need to be concerned about Electromagnectic fields on DNA. The negative effect of EMF exposure to DNA and an increase in DNA breakdown/fragmentation was mentioned in the first link. See: (1)

Research that looked for epigenetic effects on DNA that might be associated with leukemia or other cancerous changes found that Extremely Low Frequency-Magnetic Fields which have been labeled potentially carcinogenic as some association with leukemia has been noted, did not consistently lead to epigenetic changes in the study. Changes that did occur were more likely to be found when the genetic material, called chromatin, was in a more open and active form rather than when it was in the condensed, non-replicating form. (13) Pregnancy would be a time when DNA is expected to be more active and infancy and childhood are also times when growth and replication of cells is expected. Concerns and a review of available research about the risk of EMF radiation for adults and childhood development is discussed in a Special Section of the journal Childhood Development: (14)

Calcium channel blocker medications have been found to help reduce the effects of EMF radiation for individuals who seem to be more sensitive to ill effects from the form of radiation than the average person. See: (1)

Magnesium is nature’s calcium channel blocker so there may be an underlying deficiency of magnesium in the the people who are more sensitive to EMFs. A number of conditions can make the intestines absorb less magnesium and more calcium than average and the kidneys can be better at holding onto calcium and more likely to excrete magnesium than average. The food and water supply is not as rich in magnesium as it was during earlier centuries of human development. Magnesium deficiency as a risk factor in sensitivity to EMFs is discussed in the first link and it introduces a protective factor that can be increased with more variety of vegetables and other phytochemical rich foods in the diet – nuclear factor erythroid-2-related factor 2 (Nrf2). See: (1)

Specific foods or phytochemicals mentioned to help increase Nrf2 include:

  • sulforaphane from cruciferous vegetables, (such as broccoli and cauliflower);
  • foods high in phenolic antioxidants, (This is a large group including bright yellow and red fruits and vegetables, and deep purple produce. The group includes the subgroup flavonoids which include anthocyanins, flavonols, and it also includes the less familiar subgroup chalcones which are found in the commonly used fruits apples, pears and strawberries. The group also includes aldehydes which are found in vanilla and cinnamon, phenolic acids which include salicyclic acid, and tannins which are found in tea, coffee and wine. Baking cocoa and cherries, beans and whole grains are also mentioned, the summary point would be eat more fruits and vegetables; see: (11))
  • the long-chained omega-3 fats DHA and EPA, (salmon, tuna, sardines, krill oil, ground flax meal, walnuts, hemp seed kernels);
  • carotenoids (especially lycopene), (such as carrots, winter squash, sweet potatoes, cantaloupe, apricots, and lycopene is in tomato, watermelon, pink grapefruit, guava); 
  • sulfur compounds from allum vegetables, (such as onions, garlic, shallots, green onions); 
  • isothiocyanates from the cabbage group and
  • terpenoid-rich foods. (Terpenes are found in real lemon and lime oil, rosemary, oregano, basil and other aromatic green herbs).
  • The Mediterranean and the traditional Okinawan Diets are also mentioned as being Nrf2 promoting diets. See: (1)

A 2012 article that discusses the science known at the time and reviews cellphone cases designed to redirect EMF radiation away from the user available at the times suggests some health evidence exists but that the information is not conclusive yet but that no study has been longer than ten years. Children have less dense bone structure and may be accumulating more life time exposure so limiting use of cellphones around children or their use by children may be playing it safer until more research is available. (5) Turning off cellphones when not needed can save battery time and would be turning off the WiFi when it is not needed. You can always check for messages when you turn it back on again. Using a hard wired computer at home or at least turning off the laptop at night is recommended along with other tips in the first link. See: (1)

G3.5: Negative stress chemicals may cause symptoms like itching, migraines, pain or IBS.

Our bodies don’t have specific receptors just for sensing “pain.” Pain is a sign that something is wrong in the body and is sensed in a variety of ways. In medical terminology there are two main types of “pain.”

  • Nociceptive pain is associated with physical damage to the body or by sensations of pressure or heat or extreme cold. It might be due to pressure from a cancer tumor. Nociceptive pain might be described as “sharp, aching or throbbing.”
  • Neuropathic pain is caused by physical damage or pressure on nerves. It might also be due to a cancer tumor but one that is pressing on a nerve. Nerve damage can also be due to some nutrient deficiencies such as vitamin B12,  (G3.13), or other “Nutritional imbalance, alcoholism, toxins, infections or auto-immunity.” Neuropathic pain often is described as “a burning or heavy sensation, or numbness along the path of the affected nerve.” (G3.14)

Some types of pain such as migraine headaches may involve both nociceptive pain due to the pressure of inflammation or dilation of blood vessels an neuropathic pain from pressure on nerves by dilated or inflamed blood vessels.

    The next part gets complicated, some background information:

  • Calcitonin is a hormone released by the thyroid that promotes lower blood calcium levels by reducing bone resorption, (G3.15) (Bone resorption: breakdown of the bone and release of minerals, (G3.16)).
  • Calcitonin Gene-Related Peptide 1 and 2 (CGRP 1: (G3.17) and CGRP 2: (G3.18)) cause dilation of blood vessels in the heart and brain and throughout the body. Its prevalence in the Central Nervous System (CNS) also suggests that it may also have a neurotransmitter or neuromodulator role.

CGRP is produced by nerve cells in the brain and throughout the body. The protein has a role in sensations of pain. It is a member of the calcitonin family of proteins and exerts its effects at receptors that are formed from two other types of receptors.

The CGRP protein has two commonly found forms, one helps reduce pain and one helps increase it – luck of the draw. The alpha form of the protein may help reduce pain while the beta form is associated with migraine, temporomandibular joint (TMJ) pain, psoriasis and irritable bowel syndrome (IBS). The beta form is largely produced in keratinocytes found in the epidermis layer of skin. The alpha form is the type produced more within sensory nerves. (G3.19) (Psoriasis is an eczema-like condition believed to be autoimmune in nature.)

After a physical injury like a bump on the shin, inflammation causes an increased output of the Calcitonin Gene-Related Peptide (CGRP) and an inflammatory protein that is called Substance P, possibly for peptide, which is another word for protein. The release of the peptides follows shortly after an inflammatory event and shortly the chemicals are released there is  edema and plasma leakage in the surrounding area. (G3.20) The inflammatory peptides are also released in increased amounts during migraine headaches. (G3.21) The peptides increase the dilation of blood vessels and cause increased leakage from blood vessels (edema) and “degranulation of mast cells.” (G3.19) (G3.21)

Levels of CGRP increase in people who suffer from migraines and a type of prescription medication, called sumatriptan, which has been found helpful to stop migraine pain, has also been found to inhibit the release of CGRP in migraine patients. The medication may be inhibiting the release of CGRP by increasing intracellular levels of calcium. The “cytokine TNF-α” may be involved in migraine pain. (G3.21)

That was the background – the bottom line – magnesium deficiency can make the body more susceptible to the negative effects of CGRP, Substance P and chronic stress. And a chronic stress situation combined with chronic magnesium deficiency may lead to the development of inflammatory conditions like migraines, fibromyalgia, PTSD, or Irritable Bowel Syndrome. The magnesium deficiency associated with the inflammatory peptides CRGP and Substance P may be causing an increase in the level of the cytokine TNF as early as two days after a deficient diet was begun in a research study with lab animals. (G3.22)

So an Epsom salt bath or foot soak may relieve itch by providing the body with a form of magnesium that can be absorbed through the skin bypassing any GI problems that might underlie a chronic magnesium deficiency. It isn’t uncommon to have a diet low in magnesium but it is also not uncommon in the food supply. Problems with poor absorption or increased kidney or bowel loss are common causes of chronic magnesium deficiency.

A variety of tips for reducing Substance P levels are included in the article Trichodynia, Pain, and Substance P. Exercise, hobbies that use repetitive motions of the hands such as knitting, and stretching exercises may help reduce excess levels of the inflammatory chemical according to the article on the website drwardbond.com, see the article for more details: (G3.23)
