Study Shows Bright Light at Night May Raise Type 2 Diabetes Risk

The glow of a lightbulb or smartphone at night can mess with the body's circadian rhythm. Even exposure to artificial light at night, whether it be yellow light from your reading lamp or blue light from your smartphone or TV, can make it harder to fall asleep.

Now, a new study suggests that exposure to artificial light after midnight may raise the risk of developing type 2 diabetes.

the study

research was conducted among nearly 85,000 people, between the ages of 40 and 69, who wore devices on their wrists, day and night for one week, to track their exposure to different levels of light.

The health of the cohort was tracked for as long as nine years.

Those volunteers who later went on to develop type 2 diabetes were more likely to have been exposed to light between 12:30 am and 6:00 am, during the week-long study period.

study conclusions

While this study cannot prove the cause-effect connection, they do reveal a relationship between brighter light in the middle of the night and the risk of a metabolic disorder.

Those participants in the top 10 percent for light exposure at night had as much as a 67 percent higher risk of developing type 2 diabetes than those in the bottom 50th percentile.

the researchers conclude:

“Advising people to avoid night light is a simple and cost-effective recommendation that may ease the global health burden of type 2 diabetes.”

One major limitation of the study is that researchers were not able to take into account meal times, which can have an impact on both circadian rhythms and glucose tolerance.

Interestingly, light at night itself can trigger insulin resistance, as another study found. Another experiment suggest that when melatonin is disrupted and the circadian rhythm is thrown out of whack, it can lead to the pancreas secreting less insulin. This could be a contributing factor to the development of diabetes. So those two other factors are also linked.

Studies on quats: Can Hand Sanitisers Harm Your Fertility?

“Quats,” short for quaternary ammonium compounds. They’ve been part of cleaning products for decades.

Because they were invented before most toxin regulations came into place, quats are mostly “grandfathered” into the chemicals used today.

Researchers are finding more and more about the harms of quats, including on fertility. In this article, we go over what research has found out about quats.

According to a pivotal study by researchers from Virginia Tech University and the Edward Via College of Osteopathic Medicine, quats is a common ingredient in cleaning supplies that undermined fertility in both male and female mice.

the study

For the study, the researchers exposed female and male mice to quats. These were a mixture of two common quats  – alkyl dimethyl benzyl ammonium chloride (ADBAC) and didecyl dimethyl ammonium chloride (DDAC).

After five weeks of daily exposure to the quat mix, female mice spent significantly less time in heat, and after eight weeks of exposure, ovulated less frequently and produced fewer viable embryos than female mice in the control group, the scientists reported.

They found that quats appeared to impair the reproductive systems of male mice even more dramatically.

quats were used to clean the mice cages and floors

The scientists fed small amounts of the quat mix to one group of male mice for eight days.

A second group of males wasn’t dosed deliberately but for seven weeks was housed in a facility where lab staffers conducted routine cleaning with the disinfectants.

In both groups, the male mice showed lower sperm concentrations and fewer swimming sperm than a control group of mice that was not exposed to the two quat chemicals under investigation.

You can read the study published in the journal Reproductive Toxicology here.

quats harm on fertility

This adds to earlier studies linking quats to fertility risks. An earlier study by research teams from Virginia Tech and Washington State University, found that female mice exposed to the quat combination took longer to achieve pregnancy, developed fewer pregnancies. and gave birth to smaller litters.

That December 2014 study has an interesting origin story. One of its lead researchers, Hrubec, noticed that the mice in her lab were reproducing less frequently. She only discovered the link after suspecting her lab assistants’ habit of wetting their hands with quat-laced disinfectant before handling the mice!

That brought Hrubec to an article in the journal Nature about Patricia Hunt, a prominent geneticist at Washington State, who had made similar observations in her own lab in 2005.

(Hunt is famed for another lab accident, back in 1998, that led her to discover that the endocrine-disrupting chemical bisphenol A was leaching from her lab animals’ plastic water bottles into their bodies. She told EWG in 2008 that BPA exposure scrambled the chromosomes in the animals’ eggs, rendering them infertile.)

post-pandemic increase in exposure to quats

During the pandemic, many people loaded up on disinfectants, hand sanitizers, and sanitizing wipes to keep possible viruses at bay.

It even changed many people’s habits to preferring sanitisers over simple hand washing, believing that the chemical wash helps them avoid getting sick.

However, now people are exposed to quats because of widespread use of these chemicals in homes, offices, stores, schools, medical facilities and elsewhere. EWG’s research on school cleaning supplies revealed quat-containing cleaners used in multiple school districts in California.

Quats are well-documented allergens and can cause otherwise healthy individuals to develop asthma.

It is highly ironic if, in a bid to rid ourselves of exposure to possible viruses, we expose ourselves to definite toxins and develop lung diseases and breathing difficulties instead.

Must-Watch Documentaries About Toxic Chemicals

Updated 23 July 2024

Embarking on a toxin-free life can be an overwhelming and transformative experience. To help navigate this road, I have found in-depth documentaries to be particularly helpful to understand how these pollutants affect us, including: Documentary films, Multiple Chemical Sensitivity research and lectures, and related eBooks. 

This page is a resource that will help you become an informed consumer.

Living With Multiple Chemical Sensitivities

Toxic chemicals have infiltrated all aspects of modern living — household items, consumer products, electronics, food, food packaging, personal care products, soaps, pharmaceuticals, toys and play mats, and even our water supply.

Imagine having a home that makes you sick. You may make the connections much later to discover how common household items and materials like paint, carpeting, new building materials and insecticides are now your worst enemies. Your bones ache, you’re feverish, you suffer from extreme headaches, disabling fatigue, mental confusion, asthma and nausea.

You realise you are dealing with something called “MCS”, also known as environmental illness, chemical intolerance, and toxicant induced loss of tolerance or TILT.

Are you ill? Or is it your environment that is poisoned?

The longer you stay in your house, the sicker you get but you can’t imagine how or where you’re going to find a safe home. You begin to wonder if you will ever get back to feeling well, and how others respond to your “invisible illness”.

If you have imagined a stronger, more vibrant and happier you, a calm and peaceful home, you are tackling the tasks of living free of toxins. I hope this list is helpful to you and your loved ones to understand the world of MCS.

The Poison in Us All - 2023 (full documentary)

“The Poison in Us All,” a documentary by Bloomberg Investigates, explores the origins of per- and polyfluoroalkyl chemicals (PFAS) or “forever chemicals,” and how they are putting our lives and the lives of future generations at risk.

Rates of cancer diagnosis in children are increasing in Minnesota, USA, which is where chemical company 3M’s global headquarters are located. As far back as the 1960s, the company has been dumping PFAS chemicals in the surrounding areas.

Minnesota sued 3M for the damage that it has caused to the state’s natural resources, and in 2018, the company was ordered to pay $850 million for contaminating the state’s water supply for decades.

The US EPA now recognizes more than 14,000 different chemical structures as PFAS.

Homesick - 2013 (full documentary)

Director Susan Abod hits the road to learn whether other people with MCS are finding safe housing. On her journey to the Southwestern United States, Susan meets people from all walks of life. Their living quarters range from a house on stilts to tents and a teepee.

Funny, You Don't Look Sick: An Autobiography of an Illness

Director Susan Abod also made another film about MCS.

I made a film, the first documentary I made. called "Funny, You Don't Look Sick: An Autobiography of an Illness" was basically about the, you know, having this illness. And--and I took people on a tour through my house and said, 'Well, it looks like a normal place. But you know, there's no carpeting, there's radiant heat, there's no gas stove, there's no paint, nobody smokes in the building. So when I was done with that film, and you know, this was before email, it showed in 1995. And we-- it wound up going to a lot of support groups. And it was by word of mouth or newsletter or something like that. Then it dawned on me that I had this access to--in Boston, there was the American with Disabilities Act, had an arts mini grant available, and I was starting to have trouble with my housing.

I came up with the idea, how to meet others. I mean, simply what you said. And the--a film would be a great way to do it since I didn't have the resources, if I could get money in order to make my van accessible, money to hire a camera woman. So that's what I did. And we only had paper newsletters. And that's how I did it, from phone contact to phone contact to build up a tour of people to talk to. And that's how I did it. — Susan Abod, from podcast interview https://www.chemicalsensitivitypodcast.org/1970633/11732992

stink! - 2015 (Full Documentary)

STINK! a 2015 American documentary film directed by Jon J. Whelan. The film explores why there are toxins and carcinogens legally hidden in American consumer products.Award-winning film on dangerous chemical ingredients hidden in everyday products. The New York Times says, "Jon Stewart...would probably approve of ‘Stink!’” Entertaining, enlightening, witty, and at times absurd, you’ll never smell the same after Stink!”.

Addicted to Plastic - 2018 (Full Documentary)

ADDICTED TO PLASTIC is a point-of-view style documentary that encompasses three years of filming in 12 countries on 5 continents, including two trips to the middle of the Pacific Ocean where plastic debris accumulates. The film details plastic's path over the last 100 years and provides a wealth of expert interviews on practical and cutting edge solutions to recycling, toxicity and biodegradability.

Your space is your sanctuary

These documentaries expose the harms of toxic chemicals, offering insights from science, healthcare providers, and people suffering with its related health problems.

There are building biologists who have walked this path of recovery — attaining a higher level of calm to their environment and to themselves, and you can take advantage of this knowledge and guidance in creating a healthier and less stressful living and working environment.

Study: Scrotal temperature is increased in disposable plastic lined nappies

The one study that does give cloth diapers a leg up in health benefits for baby boys appeared in the October 2000 issue of the Disease in Childhood medical journal. In that article,

Disposable plastic-lined nappies have a long line of problems.

The study

German researchers measured the scrotal skin temperature in 48 healthy children aged 0–55 months (three age groups) for two 24 hour periods in randomised order (either cotton or disposable plastic lined nappies) using a portable, miniature recorder.

They found that the scrotal skin temperatures of baby boys were significantly higher when they wore disposable diapers than when they wore cloth.

They highlighted how the usual physiological testicular cooling mechanism is blunted and often completely abolished during plastic nappy use. Your baby’s bits are not able to regulate itself in a hot plastic nappy.

Higher scrotal temperatures, lower sperm counts

They suggest that prolonged use of disposable diapers as infants was an "important factor" contributing to the decline of sperm production among adult males. To make healthy sperm, you need a good environment for the sperm-producing parts of the body; that is, scrotal hypothermia is an important factor for normal spermatogenesis.

“Male reproductive health has deteriorated in recent decades. (…) increased testicular temperature in early childhood, due to the use of modern disposable plastic lined nappies (diapers), could be an important factor contributing to this decline.”

The interesting thing is that Proctor & Gamble conducted its own study and also found that scrotal skin temperatures increased for boys in disposable diapers.

Study: Fluoride in Pregnancy Linked to Worse Child Behavior Outcomes

No one should be drinking straight from the tap municipal water. It very likely has contaminants that are linked to diseases such as cancers and neuro-degenerative diseases.

Epidemiological studies have suggested that fluoride is a human developmental neurotoxicant that reduces measures of intelligence in children, placing it into the same category as toxic metals (lead, methylmercury, arsenic) and polychlorinated biphenyls.

This article focuses on a 2024 cohort study looking at the baby’s exposure in the womb to fluoride and neuro and behavioral problems in the early years.

The study

In a cohort study of 229 mother-child pairs, researchers found that higher levels of fluoride exposure during pregnancy were significantly associated with increased neurobehavioral problems in children by age 3.1 For each 0.68 mg/L increase in maternal urinary fluoride levels, children had nearly double the odds of total neurobehavioral issues reaching the borderline clinical or clinical range.[1]

They found:

  1. a higher prenatal fluoride levels were tied to a 2.29-point increase in internalizing problem scores, including emotional reactivity, anxiety, withdrawal, and somatic complaints, as well as a 2.14-point increase in total neurobehavioral problem scores.3 

  2. children of mothers with greater fluoride exposure were also rated higher on symptoms related to Autism Spectrum Disorder. As the authors note, these effect sizes are concerning given the relatively low fluoride levels in the study sample, which are typical for fluoridated areas in the US.

The JAMA study authors conclude that "there may be a need to establish recommendations for limiting fluoride exposure during the prenatal period," echoing previous calls from researchers and health advocates.

Fluoride and IQ

This study adds to a body of research going back at least decades on the impact of fluorosis on IQ.

In 2008, a China meta-analysis study examined the literature on the relationship between endemic fluorosis and children's intelligence development published between 1995 and 2007 were retrieved electronically and manually. Thirteen studies covered 2 508 children from the high fluoride group and 2 330 children from the control group.

The study suggested a negative correlation between high fluorosis exposure and children's intelligence development.

In 2023, another meta-analysis systematic review out of Italy analysed 30 studies out of 1996 potentially relevant literature records. The goal was to characterize this relation through a dose-response approach, by comparing the intelligence quotient (IQ) scores in the highest versus the lowest fluoride exposure category with a random-effects model

It concluded that their findings supported the overall evidence that an adverse effect of fluoride exposure on children's IQ, starting at low levels of exposure.

How can fluoride harm the brain?

Animal and cellular studies provide clues to the mechanisms behind fluoride's harmful neurodevelopmental impacts, including oxidative stress, neuroinflammation, disrupted neurotransmitter signaling, and altered thyroid function - all of which can derail healthy brain development.

Exposure to fluoride is linked to hypothyroidism, which negatively affects early neurodevelopment both in fetuses and newborn children (Peckham et al., 2015; Prezioso et al., 2018).

Fluoride compounds are also used in aluminum, petroleum, chemical, and plastics industries, therefore workers in such industries may be exposed to higher levels of fluoride — higher than the safety exposures — than the standard population.

You can administer fluoride yourself, with toothpastes, mouth rinses, gels, and varnishes.

Some countries take a whole community-based strategies (e.g., water, salt, and milk fluoridation), as well as individually prescribed drops or tablet supplementation. However, this raises concerns on the safety and efficacy both for dental and health in general.

Which countries in the world fluoridate their water

Water fluoridation is the adding of fluoride to a public water supply to the population. The policy was introduced in the 1930s in a bid to reduce tooth decay. It is typically at concentrations ranging from 0.7 mg/L to 1.2 mg/L.

Only three countries in the world have government/federal mandated fluoridation: Ireland, Singapore New Zealand. Only eight countries in the world have more than 50% of the population on fluoridated water: USA (70%), Australia (90%), Ireland (70%), Singapore (100%), Chile (70%), Brunei (95%), New Zealand (52%), and Malaysia (66%).

The whole of continental Europe is NOT fluoridated.

Only 10% of the UK is fluoridated.

New Studies Link Emf Radiation from Mobile Phones to Adverse Outcomes in Pregnancy, Birth, and Infant Outcomes

If you knew that the top factor that influences the health outcome of your child is something that you use every day, what would you do?

Electro-pollution is invisible radiation that is common in many homes from personal sources such as your mobile phone and the latest smart gadgets, moving subatomic particles (i.e., light in the body) at the speed of light.

It directly affects the human body's electric and biochemical responses, especially during the sensitive stages of pre and post pregnancy.

EMFs harm both the baby in-utero and the pregnant mother

In a recent study published in the journal Heliyon, researchers systematically reviewed and analyzed articles that highlight the impact of harmful electromagnetic field (EMF) radiation on physiological as well as pregnancy outcomes with regards to the mother, birth, and the child.

Electromagnetic fields disorder the body’s physiological balance, increase the lifespan of free radicals, and lead to DNA damage in individuals [22]. In addition, according to gender, density of body tissue, life cycle, and exposure, the effect of environmental pollution varies. Many sources can cause humans to be exposed to magnetic fields. Power supplies, computers, televisions, radios, and telephones are some of these resources.

We’re fundamentally bio-electric in Nature, which means every single cell process runs on bioelectricity. Any artificial electromagnetic fields has the potential to affect these processes.

The female placenta facilitates an exchange of oxygen and nutrients between the tissues of the mother and the fetus. Thus, alterations in the mother’s body can affect fetal growth and development. EMF radiation emitted from mobile phones can penetrate fetal tissues and cause hormonal imbalances in the mother and thermal, anthropometric, and cardiovascular changes in the fetus. Hence, analyzing these radiation-induced damaging effects in terms of physiological and pregnancy outcomes on the mother and the baby is important.

study: Emfs Is Linked to poorer pregnancy and infant outcomes

The researchers looked up all qualitative or qualitative studies printed in English within the past five years that reported the negative physiological and pregnancy outcomes of smartphone induced EMF radiation on mothers and child’s health in humans and animals, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) guidelines.

They found 10,450 published articles, and selected 18 articles.

The studies found that pregnant women exposed to high levels of EMF radiation had elevated levels of thyroid-stimulating hormone (TSH).

They also had higher rates of miscarriages, premature birth along with low birth weight, fluctuations in temperature, heart rate variability (HRV), altered development of the nervous system, decreased head and chest circumference, hyperactivity, and speech problems in the infant.

Emfs Is Linked to Higher Risks of Fetal and Childhood Abnormalities

The following year in 2023, another study was published. It noted that electromagnetic waves can have harmful effects on the cell components that lead to differentiation and abnormalities in cell proliferation, deoxyribonucleic acid (DNA) damage, chromosomal abnormalities, cancers, and birth defects.

It also noted that the UK showed that the prevalence of hospital admission due to congenital anomalies has increased significantly from 1999 to 2019. It also cited an Australian study from 2005 to 2015 reported an increasing trend in admissions due to congenital anomalies

It showed:

  • In mothers who have more exposure to EMFs, the odds of fetal developmental disorders in fetus were 1.34 times as many as in mothers who have no exposure to EMFs. The odds for development disorders was 2.10.

  • In mothers who have more exposure to EMFs, the mean change in gene expression in fetus was 1.02 units as many as in mothers who have no exposure to EMFs.

  • In mothers that have more exposure to EMFs, the mean of antioxidant parameters in fetus was 0.84 units lower than in mothers that have no exposure to EMFs.

What EMFs do to the human body — the fertility link

In today’s world, EMF exposure is more or less inevitable. 

Unless you live way out in the woods, where you live is a matrix of wireless routers and cellphones.

In fact, EMFs messes with your biology in a few different ways that are most directly detrimental to fertility, conception, and throughout the pregnancy process! What we do know:

  • Infertility in men. A 2014 study found that cell phone exposure reduces sperm quality. People who carried mobile phones that were actively receiving cell signals (that is, their phones were not in airplane mode) saw a significant decrease in sperm motility and viability[*]. 

  • Infertility in women. A study of 462 pregnant women in Tehran found that the women experienced a significant increase in miscarriages after exposure to EMFs[*]. On top of that, a 2015 study found that EMF exposure increased the number of viable eggs you lose with each menstrual cycle[*].

  • Decreased sleep quality. A 2019 study found that daily exposure to EMFs disrupts sleep and contribute to both depression and anxiety[*]. Another study found that EMF exposure caused people to release less melatonin, the hormone that makes you sleepy and helps you access the deepest, most restorative stages of sleep[*].

  • Mental stress. EMFs cause concentrated oxidative stress in your brain[*][*]. A series of recent studies suggest that EMF exposure could even be a cause of neurodegeneration as you age, contributing to diseases like dementia[*][*]. This is the total opposite of what we want to mothers during postpartum recovery when the brain is adjusting to a whole new life with baby!

Mothers are increasingly exposed to environmental toxins

How much EMF exposure before it causes harm? It depends on gender, density of body tissue, life cycle, and exposure…

And for pregnant women, exposure to children begins in the womb. Women and babies (including in the womb) are also softer and more vulnerable to the penetration to EMFs.

With the increase in the modernity process and the increase in exposure of mothers to environmental pollutants, the hospital admission rate due to congenital malformations has increased by almost 19% from 1999 to 2019.

Any older mother visiting a gynaecologist’s office is well aware of the script — that mothers above 35 years have an increased risk of congenital anomalies by 3.93 times and the risk of spontaneous abortion by 12.82 times…
