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. (6) 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 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 risk of infection or 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)

Autoimmune Trivia – clothing choices for health

I have a new ugly sunhat and it gets just as many funny looks as the last ugly sunhat – sometimes there is no winning solution if you are unhealthy except to do what you have to do to stay healthy. I thought the new hat was slightly less odd as it’s a straw hat, summery, but oh well. I need a broad brim for sun protection. Cute hats don’t always have a brim or a large floppy beach hat has too much brim and can obstruct your ability to see.

Due to a tendency to develop severe rashes or eczema I need natural fibers. Modern fabrics can leave me itching and as my autoimmune disease has worsened I’ve even had problems with rashes that lead to a lack of skin – an open sore over a large patch is painful more than itchy. Fashion may be fun but not as much fun as having skin. Sewing my own clothes allows my own fabric choices. Hunting through resale shops for natural fiber clothing can be another way to find items that don’t make me sick. Organically grown cotton products are available in limited styles and limited places for a price that is generally more than a department store price but probably less than an expensive fashionable brand.

Laundry detergents or fabric softeners can also leave me with an allergic reaction. Having overactive white blood cells means the allergic and autoimmune sensitivities are more likely to occur – there is one bonus, cancer cells may be more likely to be identified and removed. Until it is a severe condition someone with autoimmune disease may be less likely to have cancer due to the overactive white blood cells. Increased inflammation in a patient and those with “dermatomyositis,” type of infllammatory autoimmune disease were more associated with cancer risk than some other types of arthritis like autoimmune diseases, “systemic autoimmune rheumatic diseases (SARDs), in a large study.” [3] Someone with autoimmune disease can be at greater risk of developing another type of autoimmune disease however. [1]

Adequate treatment of hypothyroidism might have an additional benefit of reducing risk of demyelination and development of Multiple sclerosis. [1]

“For example, an intriguing finding based on a rodent model of chronic demyelination indicates that administration of thyroid hormone can enhance remyelination under certain conditions (3132). Relevance of this finding to multiple sclerosis in humans is unknown, but, hypothetically, routine treatment of hypothyroidism could diminish the risk of multiple sclerosis.” [1]

The sunhat is helping reduce inflammatory reactions that can make underlying autoimmune symptoms worse. Oxidative stress is another way to say inflammatory reactions and a variety of things in addition to excessive sun exposure can lead to oxidative stress and increased production of free radicals – a type of reactive chemical which antioxidant foods helps to detoxify safely rather than allowing an increase in negative health symptoms. Pollution and smoking can also be external factors in addition to excess sun exposure which can be a cause of inflammatory oxidative stress. [2]

Eating adequate but not necessarily excessive amounts of antioxidant rich foods can help the body detoxify the free radical chemicals safely. Excessive supplements or very rich food sources of antioxidants can tip the chemical balance too far in the other direction. Studies with supplements of vitamin E and vitamin A found that some is good but more isn’t. Sesame seeds are a good source of a variety of nutrients and have been tested for helping with the oxidative stress caused by athletic exercise, two tablespoons per day were found to be a helpful and safe amount. See: Effects of Sesame (Sesamum indicum L.) Supplementation on Creatine Kinase, Lactate Dehydrogenase, Oxidative Stress Markers, and Aerobic Capacity in Semi-Professional Soccer Players. [4(G3.8)]

Flavanols found helpful at reducing age related memory loss

A small patient based study found that flavanols concentrated from cocoa beans helped improve age related memory loss. The concentrated flavanol extract was prepared by Mars Inc., the company sponsoring the research. The study followed 37 healthy volunteers between the ages of 50 to 69 for three months. Participants in the experimental group consumed 900 mg of the flavanol extract and participants in the control group consumed 10 mg of the concentrated flavanol cocoa drink. Participants were given brain scans at the beginning and end of the study. The brain scans were being monitored for any changes to the dentate gyrus region of the brain which is suspected to be involved in age related memory loss. A twenty minute memory test using pattern recognition questions was also used to assess any memory changes in the study participants. At the end of the study participants on the high-flavanol diet scored significantly higher on the memory test than participants on the low-flavanol diet.

This is a preliminary research study that used a concentrated extract of flavanols. The dose used in the study would not be available from regular chocolate products. There are many plant sources for flavanols in addition to cocoa beans. More research is needed. [link]

In the mean time eating five to nine servings of fruits and vegetables per day may help reduce cancer risk while providing some healthy flavanols and flavanoids. Blackberries, apricots and apples with the skin are sources of flavanols. And green tea, black tea, and red wine are good sources of flavanols in addition to cocoa beans. [link] Increasing use of green leafy herbs may also be helpful to health. Oregano, rosemary, sage and summer savory may be good sources of a variety of antioxidants including the flavonol quercitin and the flavanoid rosmarinic acid. [link] [link]
