Epigenetic changes may also be involved in Covid19 or LongCovid

Epigenetic changes may be involved in Covid19 and LongCovid, which might be able to be changed back with the addition of plenty of methyl donor vitamins. People with methylation genetic alleles would be more at risk for epigenetic changes to DNA or actin protein filaments. Actin are semi flexible proteins in a double helix shape which support the fluid and organelles inside of cells and around cells and organs of our bodies. Actin also is involved in guiding the work of DNA replication and growth and development of cells or infants.

Methylation is the addition of a methyl group – one carbon atom and three hydrogen atoms, to genes, or actin filaments. A methylated gene is not active for encoding proteins while a demethylated gene is available to be transcribed into a messenger mRNA to be made into a matching protein. Actin filaments are a double helix shape like DNA but do other functions throughout our body. Some have methyl groups also that seem to be essential for proper function of the actin protein whether in muscle contraction or in guiding chemicals within cells to make DNA or do other work. Actin filaments add structure to the jelly like fluid around and in cells and may tether chemicals in place for chemical reactions or guide cellular organization during growth and development.

Actin may be involved with energy fields of our body along with microtubules also, but that is not discussed in greater detail in this post (more information about quantum energy fields and actin is included in Cracking Nature’s Code (2019) (1), and in several posts on another site of mine first in the series, 2nd, 3rd, 4th).

Viral infection and epigenetic changes with a focus on Postural Orthostatic Tachycardia Syndrome and possible dietary and lifestyle changes that may help reverse epigenetic changes is the focus of this post – which got long. It is also available as a section of this document that includes the series on Mast Cells and Histamine. Current standard of treatment for patients with POTS symptoms may leave them unwell for years – a few get better more rapidly. I got better on my own within a few months – twice. More about possible strategies for improvement of epigenetic changes will be included later in the post. More about the epigenetics involved in POTS is included in the Genetics/Epigenetics chapter of my book draft which is available on a platform where you can get an e-copy early (minimum price Free, Leanpub/Tipping The Clock Toward Health) and then be informed of updates with an email subscription.

Viral infection can cause Epigenetic changes.

Bacterial (Pacis et al., 2015, 2) and viral infection (Lichinchi et al., 2016, 3) directly impact methylation patterns, most likely orchestrated by actin since it is universally hi-jacked in viral infectivity (Cudmore et al. 1997, 4; Ohkawa and Volkman, 1999, 5; Lu et al., 2004, 6; Marek et al., 2011, 7).

I found I have methylation gene alleles in a genetic screening (post: Methylation Cycle Defects – in me – genetic screening “for research purposes only”). Since finding out I stopped taking standard supplements of B12 and folic acid because they are not methylated, not bioactive. I take methyl B12 & methyl folate supplements now. Postural Orthostatic Tachycardia Syndrome (POTS) (9) has been a problem for me in past years a couple times and I got better. Symptoms include a rapid heart rate, tachycardia, and feeling faint or blacking out, especially when getting up quickly from a seated or laying down position to standing. (9) I have heard anecdotal reports of it being a symptom for some LongCovid survivors who had never had the problem before.

To slow the rapid heart rate during an episode I found it helpful to stop and sit or lay down with my feet above my heart if possible and just wait a couple minutes for the rapid heart rate to slow again. Continuing to exercise would make the rapid heart rate worse. Preventing the faintness upon rapidly getting up required trying to remember to slow down and have a support ready to hold if I felt wobbly. I did faint once, odd to find yourself on the floor unexpectedly.

POTS has been found to potentially involve a genetic difference in the norepinephrine transporter gene (SLC6A2) sequence and it can also be an epigenetic problem with links to excess formaldehyde. (9) Formaldehyde can donate methyl groups to DNA that normally would be unmethylated – active. (10) Methylation of DNA is a little like a on/off switch for genes, or the cap on bottle – add the methyl groups and the DNA gene is inactive.

Formaldehyde as a methyl donor for the methylation of DNA, RNA, and histone acts as an epigenetic factor participating in the reversible and dynamic methylation. DNA demethylation elicits formaldehyde generation in the dividing cells and post-mitotic neurons.” (10) Memory formation involves methylation of DNA and cognitive impairment in older adults is associated with increased internal formaldehyde levels (self-made) and demethylation of DNA. Use of nutrients to remove formaldehyde helped improve memory in an animal based study. (10)

Formaldehyde can be prevalent in secondhand or thirdhand smoke in enclosed rooms, or smog, or we make our own during normal metabolism, and physical or emotional stress conditions may cause an increase, as well as the level potentially increasing in older adults. (11) Elevated levels of formaldehyde within cells causes more breakdown of sugar for energy and increased removal of an antioxidant out of the brain cells, which may increase risk for cognitive damage. “As excess formaldehyde accelerates glycolysis and glutathione export in neural cells, formaldehyde‐induced alterations in brain metabolism and oxidative stress may contribute to the pathological progression of neurodegenerative disorders.” (11)

Formaldehyde is very reactive and can use the methyl group to form links between protein groups or parts that wouldn’t normally be linked – like bungee cords holding parts together in places that would be separate in normal function. (11) Formaldehyde is used with tissue samples to preserve material for viewing under a microscope. Studies of the effect of formaldehyde on the actin protein of live cells that were low on blood sugar found that modifications to the protein did occur – the authors suggest any prior research on the actin protein in formaldehyde treated samples may be inaccurate. (12) Take home point – formaldehyde is not good for our brain cells and may effect the protein of our brain cytoskeleton structure. (12) Protein tangles in brain cells are associated with dementia and autism.

What is a cytoskeleton? We are mostly water, so how do we walk around? With a balance in tension between string like ligaments and muscles and rod like bones of our skeleton. Within the cellular environment, inside and outside the cell membrane – the tent wall, there are rod like microtubules and string like actin protein that is more flexible, it can change shape but isn’t stretchy as much as structurally able to modify in shape. Actin is a double helix, two spirals like DNA except without the ladder like steps joining the two lengths of protein. When force is applied the double helix can get a little longer or shorter as the coils compress or lengthen slightly – tensile strength – and the protein gets stiffer from a side to side direction – torsion – and is less flexible along the length, less able to bend sideways. (13)

The actin protein may act as torsion sensors – is the environment changing in pressure around that section of the protein length – from increased fluid or gas? How full is the balloon like membrane? (14) Channels in a membrane will open and start to leak rather than letting the membrane burst like an overfull balloon. This may seem like a silly discussion – however it is your brain and organs – leaking is better than bursting. Leaking membranes will release fluid and some types of chemicals while a bursting open, as when viral replication is complete and the virus exit a cell, the membrane bursts and all the remaining chemicals in the cell flood into the surrounding cytoskeleton and can cause inflammatory damage to surrounding cells.

These flexible yet firm cytoskeleton actin filaments also may act like guidelines for directing traffic or tethering organelles in place for activity such as replication of DNA during cell division (one cell doubles its DNA and then divides into two cells). Too much of the proteins within a cell nucleus will prevent DNA replication rather than guiding it. (15) Actin is also involved in muscle fiber motion. The double helix structure can also be methylated with methyl groups doing an unknown but critical function. Loss of methylation of actin in one location is associated with cancer and autism spectrum disorders, (16), loss of it in another location along the protein chain is associated with muscle changes that cause female animals to have delivery problems and fewer babies. (17, 18)

So actin is important stringy protein that effects muscle power, cell division, and the brain – and formaldehyde can cause demethylation of DNA, likely it can cause demethylation of actin also which may lead to autism spectrum disorders, cancer, and muscle problems that can affect a healthy delivery of infants (in an animal study). The visual – we want our jelly like insides to have a strong yet flexible tent membrane, tent poles (microtubules), and tie downs (actin) – without having so many tie downs it starts looking like a haunted house full of cobwebs. The amyloid beta protein associated with Alzheimer’s dementia and autism may be protective against a low level infection (post: Magnesium might help protect against beta amyloid placques) but also may increase changes in actin stress fibers (24) and an excess seems to add to chronic inflammatory damage over time.

How do we achieve this? Healthy actin?

It may help promote appropriate methylation of DNA and actin to have adequate antioxidants and methyl donor nutrients in our diet, to reduce oxidative stress chemicals and provide adequate methylation to DNA and actin. Avoiding excessive physical and emotional stress may also be an important strategy, so we aren’t embalming ourselves with self produced formaldehyde (the mummy in the haunted house being our own brain).

We also want to avoid formaldehyde in our environment, which would include improving air quality, especially during sleep hours when our body is focused on detoxification of the brain. Parkinson’s Disease is another chronic condition that may involve epigenetic changes and reducing formaldehyde exposure may be protective. More information is in this post with a link to a longer post about formaldehyde sources: The Cholinergic System

Increasing methyl donor vitamin rich foods and/or supplements should focus on the methylated form if unsure whether there is a genetic allele problem causing lack of methylation.

Methyl groups are important for numerous cellular functions such as DNA methylation, phosphatidylcholine synthesis, and protein synthesis. The methyl group can directly be delivered by dietary methyl donors, including methionine, folate, betaine, and choline.” … “Studies that simulated methyl-deficient diets reported disturbances in energy metabolism and protein synthesis in the liver, fatty liver, or muscle disorders.” … “Hypomethylation has a wide spectrum of effects that include genetic, epigenetic, and metabolic alterations.” (8)

Gastrointestinal problems have been found to be common among patients with Postural Orthostatic Tachycardia Syndrome (POTS) with malfunction or slowing, dysmotility, of the smooth muscle lining of the intestinal tract. “Case study 1: A 20-year-old woman presented to clinic for further evaluation of a several year history of fullness and epigastric discomfort associated with eating and irregular bowel habits. Her weight was stable. She also described frequent migraine headaches, episodic palpitations and lightheadedness with progressively increasing episodes of syncope. A systems review was notable for profound fatigue, dry eyes and mouth and intermittent flushing and pruritus.” (19) The patient’s symptoms include many in common with Mast Cell Activation Syndrome, however testing for mast cell activation was normal. Patients whose symptoms followed a viral infection tend to get better more often than patients with a family history of POTS. (19)  

A number of chronic conditions are frequently seen in patients with POTS and contribute to symptom burden and reduced quality of life. Common comorbidities include chronic fatigue syndrome, fibromyalgia, interstitial cystitis, and migraine headaches. Other unique conditions that seem to occur with increased frequency in POTS are autoimmunity, the hypermobile form of Ehlers-Danlos syndrome (HM-EDS), and mast cell activation disorder (MCAD).” (19)  

“Unlike mastocytosis, idiopathic mast cell activation [MCAD] occurs in the absence of mast cell proliferation and with episodic accumulation of mast cell mediators in the plasma or urine, usually present when symptomatic. Patients with MCAD typically present with episodic “attacks” of flushing, urticaria and pruritus accompanied by lightheadedness, dizziness, dyspnea, nausea, headache, diarrhea, and/or syncope; symptoms representative of the hyperadrenergic type of POTS with biochemical evidence of MCAD (20).” (19)

The patient in case study 2 had ongoing nausea, vomiting, abdominal pain, and weight loss continuing for years following a viral infection. She was found to have deficiency in iron, zinc, and vitamin B12 and gastroparesis (slow or little intestinal muscle action). Intravenous iron and B12 were provided and an oral zinc supplement. Nutrient levels improved however the GI symptoms and weight loss continued and the patient was given tube feedings which improved weight, however some intolerance to the tube feedings continued and abdominal pain persisted. (19)  

If demethylation of actin protein in the muscle tissue of the intestinal wall was a problem for the patient in case study 2, then it may have been a factor in the gastroparesis. Genetic screening for methylation defects is not mentioned. Supplements of B12 are often an unmethylated form, cyanocobalamin, and which include cyanide. (21) In a study of 12 patients by Huang et al, (22): “Disturbances in GI motility were found to involve not only the stomach, but also multiple segments of the gut spanning the esophagus to the anus.” (19) The commonly used treatments for GI symptoms associated with POTS (see Table 5) do not include nutrients and do include proton pump inhibitors, (19),  a medication that takes the place of magnesium as a calcium channel blocker, and which may lead to worse magnesium deficiency for some people, a genetic difference may be involved. See post: Original Prilosec Warning, edited.

Small intestinal bacterial overgrowth (SIBO) may occur along with GI problems and lead to fat and carbohydrate digestion and absorption problems and bloating from excessive bacterial growth. Changes in diet due to the discomfort are common in patients with POTS and these more severe GI symptoms and which may lead to deficiencies in fat soluble vitamins A, D, E and K. Megaloblastic anemia may result from deficiencies in iron, folate and vitamin B12. (19) Sulfate deficiency may be an underlying factor (23) and providing Epsom salt soaks of the lower legs and feet, or in a bath one to two times a week might help by providing a topically absorbed form of magnesium and sulfate. See post: To have optimal Magnesium needs Protein and Phospholipids too.

Zinc is also involved in DNA methylation and deficiency of the trace mineral can lead to epigenetic changes and gene transcription problems. Zinc is needed along with actin and other proteins to tell the cell nucleus and cell which genes to make into mRNA to be encoded into a protein. “Accumulating evidence has demonstrated that several key enzymes and zinc finger proteins with zinc atom(s) in the reactive center and binding site play important roles in DNA methylation and histone modifications. Therefore, zinc deficiency may disrupt the functions of these enzymes and proteins and result in epigenetic dysregulation. Furthermore, zinc deficiency may enhance inflammatory response and subsequently alter DNA methylation status of the genes involved in inflammation.” (20) Also see posts: Zinc – big news, CoV and other illness related, and Zinc, cancer, and bitter taste receptors.

Breast milk is best for baby – and for the workplace, healthy infants > fewer sick days

A pair of substantial mammary glands have the advantage over
the two hemispheres of the most learned professor’s brain
in the art of compounding a nutritive fluid for infants.
– Oliver Wendell Holmes (todo.7) (Substantial isn’t necessary, small but fully mature breasts can make plenty of milk for baby too. – Enough food in well balanced amount for mom is still essential however.)
Breastfeeding is an instinctual and natural act,
but it is also an art that is learned day by day.
It is almost always simply a matter of practical knowledge
and not a question of good luck.
– La Leche League (todo.7) (Moms and babies both can use a little guidance from someone who has experience with the mechanics of positioning and suckling – like riding a bicycle mom has experience with the second and later children but even then the babies still may have difficulty and some guidance may be helpful even for an experienced mom. La Leche League is a volunteer group dedicated to helping promote and help successful breastfeeding relationships between mothers and their infants.)
When we trust the makers of baby formula
more than we do our own ability to nourish our babies,
we lose a chance to claim an aspect of our power as women.
It is an act of female power,
and I think of it as feminism in its purest form.
– Christine Northrup (todo.7) (Infant formula is a blessing for those who are unable to make sufficient breast milk or for babies who don’t tolerate it well or need other specialized nutrition support but there are immune and autoimmune factors that help the infant that only mom herself can make. Human milk also has factors that support a healthy intestinal microbiome (good guy bacteria) and phospholipids which can help promote a healthy appetite and positive growth rate in the infant. While chocolate has a tiny amount of caffeine, its source cocoa beans also have a good supply of phospholipids, choose a lower sugar, lower fat dark chocolate or use Baker’s chocolate and make your own chocolate treats to maximize the phospholipid and other antioxidant content. Pomegranate seeds also contain a good supply of phospholipids, (pomegranate seed oil analysis, P.14) cardamom spice, (P.15), and dark green leafy vegetables and herbs such as oregano, basil, and rosemary are also good sources. Phospholipids are found in membranes and are more plentiful in nuts, seeds and other leafy vegetables. Pumpkin seeds are a good source. (P.8 , 9, 10)
Pumpkin seed kernel oil is being investigated as a medical treatment and was found to be more effective for wound healing in an animal study than the standard wound care ointment or no treatment control groups. (P.11)
Pomegranate seed oil has been investigated as a dietary supplement in an animal based study and found to positively affect fatty acid balance. The discussion suggests consideration as a dietary alternative source for the beneficial fatty acid CLA, Conjugated Linoleic Acid. (P.16)
To do – write this up in more detail for the effectivecare.info website, initially intended for the gender discrimination section 11 of the policy part but additional information on the health benefits of pumpkin seeds /the food information was added to the home page, I still need to do the additional breastfeeding section though/ – to explain the (todo.footnotes). The reference list below includes notes to expand on at a later time.
In the meantime – pumpkin seed kernels are the inner green part that have been shelled. Their texture is similar to sunflower seed kernels but their oil content has a more health promoting nutrient balance than the oil content of sunflower seed kernels. Ideally shop for raw pumpkin seed kernels that are not salted. Salted, roasted pumpkin seeds may also be labeled Pepitos and the salt content may be excessive if eaten in much quantity. An 1/8th to 1/4 cup of raw pumpkin seed kernels, 2 to 4 Tablespoons might be a reasonable serving size of the unsalted type or lightly salted and roasted types. Roasting the seeds increases the phospholipid content but also increases some more negative oxidation chemicals which would decrease some of the benefits of the oil. (P.12) For freshness of the roasted snack, the raw pumpkin seed kernels can be lightly pan roasted for a few minutes with a dash of oil until they puff a little. Toss with a sprinkle of salt and let cool on a paper towel to absorb extra oil. Store any extra in an airtight container to retain crispiness and prevent further oxidation.
(Oxidation of seeds or nuts: spoilage of the oils due to contact with oxygen from the air. Storing all nuts and seeds in airtight containers in a cool or even freezing temperature extends their safe eating shelf life. Rancid oil has a recognizable odor and bad taste and nuts and seeds should be discarded rather than eaten if they have gotten too old and turned rancid as the oxidized oils can be unhealthy, especially if eaten in a larger quantity. One or two wouldn’t be a problem but once the off-taste is noticed throw away the remainder of the package or possibly you might be able to return it to the store if it was a recent purchase. (P.13))
I discuss pumpkin seed kernels as a prenatal healthy food that might help prevent high blood pressure problems on the home page of the website effectivecare.info. It is still a work in progress, un-peer reviewed and draft version in some sections but potentially life saving information is something that I feel deserves to be shared, even if in draft version. The more life threatening type prenatal complication that can include high blood pressure called pre-eclampsia is also discussed in more detail on that website, Preeclampsia and TRP Channels, based on information that has helped former prenatal clients I’ve helped and with more recent information and ,medical hypothesis research posted online by others.

Breastfeeding Medicine, 6/12/2010 https://bfmed.wordpress.com/2010/06/12/what-does-feminism-have-to-do-with-breastfeeding/ (todo.2), Discusses the value of breastfeeding and the issue of class and choice. Women have to be able to afford to have the time off work to be able to breastfeed for the recommended six months, best for baby. If work place policies were more supportive of all women being able to breastfeed, or pump at work, then there wouldn’t be a class issue rich can afford and poor can’t, or seemingly antifeminist, Stay at Home Mom versus Working Mom.

Also mentions the difference in life expectancy between men and women and that women living longer are also having more medical expenses to pay on average, over the longer average lifespan.

Formaldehyde: Health risks, and Environmental and Dietary sources.

I mentioned in my last post, (a long time ago – I’ve been busy spring cleaning), that I would discuss oxidative stress next – some background information first:

(“Formaldehyde is a cause of oxidative stress.” LMGTFY: 1,450,000 results.)

Formaldehyde:  formaldehyde is a chemical that can be produced within the body as part of metabolism, it is toxic however and the body would continue to break it down further for removal from the body in conditions of normal health. Formaldehyde is found in the environment from a variety of sources and is produced in the body or in food products as a metabolite (a chemical produced from the digestion/metabolism of a larger chemical) of some alternative sweeteners (G.48) and other dietary sources including fruit juices and artificial and natural flavorings. ((G.49, (p476, G.50)) (G.56)  “Formalin” is chemically very similar and may cause similar health symptoms. (G.42(G.25Formalin is used to induce pain in lab animals for experimental purposes and it was determined that the pain was due to activation of the TRPA1 channels. (G.86)

Environmental and dietary sources of formaldehyde include, (G.56):

  1. First and second hand smoke, (G.44); The formaldehyde content of some types of E-Cigarette preparations used for “vaping” instead of smoking the volatile gases have been found to vary significantly. Skipping to the last point on this list may provide the explanation – fruit flavoring based on fruit juice and essential oils from fruit and other artificial “flavorings” are frequently chemicals from a group of chemicals called aldehydes. They can break down over time into smaller chemicals which can include formaldehyde or other toxic types of aldehydes. (G.49) So if you are “vaping” in order to avoid toxins in cigarette smoke then it may be advisable to skip the “chocolate or fruit flavoring” and use an E-Cigarette product that just has the natural tobacco flavor instead. (Yes, tobacco is an herb and it has a flavor and nicotine can have some health benefits, however formaldehyde does not. The nicotine patch provides a steady dose of nicotine without any volatile toxins.)
  2. Poorly ventilated air or smog; (G.45)
  3. Vinyl and PVC plastic products off-gas formaldehyde and other volatile chemicals at levels that can make a sensitive person feel ill. (G.45). A poorly ventilated room would increase the risk of the gases accumulating to more toxic levels. The wax refinishing treatments used to clean and shine vinyl flooring are also sources of formaldehyde and other toxic gases. One re-waxing session can produce as much volatile chemicals from the chemical products that are used to strip off the old layer of wax polish and add a new layer, as the vinyl floor itself would off-gas throughout all the years of its installation. So making a choice about which type of flooring to install is also making a choice about the  type of cleaning products that will be needed to maintain the floor. (G.46) A Cleaning Product Fact Sheet is available from the California Environmental Protection Agency Air Resources Board: (G.47). Types of flooring and other building materials are discussed in extensive detail in a review article regarding sources of Formaldehyde in the Indoor Environment: (G.45).
  4. Metabolites of the breakdown of the alternative sweetener aspartame and Neotame include menthol and formaldehyde. (G.48)  
  5. Older packages of fruit juice also may contain formaldehyde in amounts that can continue to increase as the product ages. The formaldehyde is produced as other chemicals become unstable over time and metabolically breakdown into a variety of smaller chemicals which include formaldehyde. The food preservative method of ionizing radiation has been found to increase the chemical breakdown of larger aldehydes in apple juice into formaldehyde and other chemicals with toxic properties. (p476, G.50)
  6. Before leaving the topic of formaldehyde, the symptoms of toxicity with workplace exposure to formaldehyde have been reported to include allergic type symptoms including: “sneezing/airways-related symptoms, itching and watery eyes.” (G.51) Formaldehyde exposure may also be a cause of systemic allergic contact dermatitis, (G.52, G.53, G.54), possibly even with symptoms of rash occurring on the eyelids.(G.55) A diet designed to avoid formaldehyde intake may be helpful for alleviating the eczema like rash. (G.52)

A summary, in reverse order;

Formaldehyde might be accumulating from several sources, (G.56):

  • Workplace exposure; Workers more at risk might include health professionals, (G.51); and hair stylists or nail salon technicians, (G.58); and funeral directors may be more at risk for developing the paralyzing chronic disease ALS, (G.59); some industries such as the garment and textile industry may have formaldehyde exposure, (G.63);
  • Aseptically packaged juices, the amount may collect in older packages as the product ages, ionizing radiation methods of food preservation have been found to increase the amount of toxic aldehydes including formaldehyde and therefore is not a recommended technique for the juice industry, (p476, G.50);
  • Nutrasweet (aspartame) and Neotame, alternative sweeteners. (G..48)
  • Vinyl flooring, cleaning products, and other PVC type of plastic products. (G.45, G.46, G.47);
  • Poorly ventilated air or smog. (G.45); *Note, lighting large numbers of decorative candles may be increasing volatile chemicals in your air supply. Also air fresheners and cleaning products may contain chemicals that break down into formaldehyde. (G.60) Lifestyle choices besides smoking cigarettes can negatively affect health. Try a fern for air freshening instead; give it a nickname and you might get some emotional benefits in addition to other physical health benefits. Plants can be useful household decorations because some types can clean the air of formaldehyde and other toxins. The original research was by a NASA scientist for use in keeping the air fresh in living environments for astronauts. For the most effective air cleaning ability, the plant does need to be watered and misted as its particular type requires, because the chemical removal of formaldehyde from the air is dependent on the roots and leaves access to water. (G.61); a mechanical problem with the furnace or water heater and ventilation system may be leaking toxic chemicals into the building’s air supply; increased efficiency of insulation and other building materials have created rooms and buildings that are too good at preventing air circulation, which makes maintenance and cleaning of ventilation systems and fans important – otherwise everyone working or living in the space might start feeling some symptoms of “sick building syndrome.” (G.62)
  • Smoking cigarettes or other products, and flavorings in “vaped” E-Cigarettes may also be a source of formaldehyde. (G.44, G.49)

Fact Sheets regarding Formaldehyde, Environmental Safety and Health:

  • The Centers for Disease Control provides a fact sheet for further guidance regarding risks and precautions regarding formaldehyde: What You Should Know About Formaldehyde, (G.57)
  • The Environmental Protection Agency provides a fact sheet on sick building syndrome: Fact Sheet: Sick Building Syndrome, (G.62)
  • The Cleaning Products Fact Sheet, by the California Environmental Protection Agency’s Air Resources Board provides guidance regarding safer cleaning products: (G.47)
  • The National Cancer Institute’s Fact Sheet: Formaldehyde and Cancer Risk includes research on occupations that may be at risk for formaldehyde exposure and provides a list of organizations that might have more information or other help to offer. (G.63)

Sick Building Syndrome: Symptoms that may occur due to breathing air that contains too much formaldehyde may include sore throat, cough, scratchy eyes, and nosebleeds according to the fact sheet by the Centers for Disease Control. (G.57) So if everyone working in a building, or many workers or family members are all experiencing allergies or a slight cold that just doesn’t seem to want to go away – then bad air may be a problem. See the fact sheet on Sick Building Syndrome by the EPA for more information. (G.62)

Eczema: The eczema symptoms reported in medical research may occur with more chronic long-term exposure to formaldehyde and/or in individuals who also have more difficulties metabolically with detoxifiying formaldehyde – we don’t know all the answers. I have personally experienced skin rashes off and on all my life and was startled to develop it on my eyelids in my more recent past – and then was more startled, or more relieved to learn of the possible cause – formaldehyde exposure (G.55) and systemic allergic contact dermatitis, (G.52, G.53, G.54) Poor air quality was a problem at the time in part due to water heater mechanical problems, and also first and secondhand smoke were contaminants in my air supply – I cleaned up and changed habits somewhat and my eyelid rash got better – yeah science! To me that seems like an example of effective self care and effective use of evidence-based medical research even if I had to read it on my own.

Other health risks include cancer and neurological conditions: The link between cancer and formaldehyde may be less strong than for neurological disorders such as ALS in funeral home directors, (G.59), or autism in a child whose mother had prenatal exposure to formaldehyde, (G.56), however research has found some cancers associated with occupational exposure to formaldehyde. The National Cancer Institute also has a fact sheet on the topic of formaldehyde and it includes a convenient list of addresses and websites for organizations that might have more information for workers concerned about exposure risks such as OSHA, the Occupational Safety and Health Administration,. (G.64) See the National Cancer Institute’s Fact Sheet: Formaldehyde and Cancer Risk for more information and resources regarding formaldehyde and occupational safety: (G.63)

Houseplants can help offices as well as astronauts:

If you are looking for a hair salon that is likely to have less formaldehyde and other volatile toxins in the air then look for one with lots of healthy ferns and other tropical low light houseplants. (G.61) If you are a hair salon or other business owner interested in improving the air quality in your establishment with the help of ferns and other houseplants, then hire a staff member who knows and loves plants because they do require some consistent care that can vary quite a bit depending on the type of plant – or buy the book by the NASA research scientist and have an employee learn how to care for your indoor air-cleaning garden.

The scientist, B. C. Wolverton, organized what he learned to help astronauts in an easy to use plant guide that lists the species of plants which were found most effective at cleaning air. The book, How to Grow Fresh Air: 50 Houseplants that Purify Your Home or Office, includes guidance for caring for each species and also lists them by the types of volatile chemicals that they were able to remove from the air. (G.66)

Large urban areas may have office plant services available where a greenhouse or florist shop supplies and maintains lovely office plants for a subscription or rental type of payment. An employee of the plant business has a route of subscribing businesses to visit each week in order to water, mist, and trim plants of any dead leaves, even a healthy plant will look sad if it is covered in a layer of dust and has a few dead leaves. Plants that are sick are simply returned to the greenhouse for care or recycling and the empty spot is filled with a replacement by the plant business employee.

Ambius is an example of an office-plant company with service locations available in many urban areas in both Canada and the United States. See the Ambius website for more information and service locations: Ambius.com.

A U.S. Congressman is seeking a DOJ investigation of glyphosate

The U.S. Congressman Ted Lieu has called for a Department of Justice investigation of the chemical glyphosate used in the herbicide Roundup. There may have been collusion by an EPA worker and Monsanto to suppress investigation of the chemical’s health risks. It has been labeled a likely carcinogen.

“New questions about the safety of Monsanto weed killer Roundup are deeply troubling. I worked on the glyphosate issue last term and I believe consumers should immediately stop using Roundup, whose core ingredient glyphosate has been labeled a likely carcinogen and has been linked to non-Hodgkin’s lymphoma by the International Agency for Research on Cancer. We need to find out if Monsanto or the Environmental Protection Agency misled the public.”
