Blue Light Can Shorten Your Lifespan and Harm Your Brain

Blue light can cut your lifespan. We already know too much blue light from too much screen use has been linked to mitochondrial issues such as obesity and psychological problems. But did you know blue light can cut your lifespan short? 

What Is Blue Light?

Blue light is very high-energy short-wave light. Vibrating within the 380 to 500 nanometer range, it has the shortest wavelength and highest energy.

In Nature, the only source of blue light is from the Sun, but it always comes balanced with other colour spectrums. So is any blue light coming from traditional heat based lights. 

Artificially, however, fluorescent bulbs and LEDs, mobile phones, computer screens, and flat screen televisions emit high amounts of blue light. 

Check out the colour spectrum from the Sun — it offers the full spectrum of colours of the rainbow. Heat-based light bulbs provide a warm glow with relatively balanced light and almost no blue light. See the colour spectrum from a standard LED. It is practical nothing but blue light.

The image shows comparative spectra for different types of light.

Blue Light Accelerates the Biological Aging Process in Fruit Flies

A problem with LEDs and many of the screens and devices we are surrounded by is that they have a blue spike. I've read various articles on the biological effects of too much isolated blue light on people

One huge study discovered how blue light emitted by phones, tablets, televisions, and other gadgets can substantially accelerate the biological aging process in fruit flies (Drosophila melanogaster). 

They found specific metabolites (cell essential chemicals) become altered in the cells of fruit flies exposed to blue light. 

One metabolite they found was that the levels of the metabolite succinate were increased, but glutamate levels were lowered:

“Succinate is essential for producing the fuel for the function and growth of each cell. High levels of succinate after exposure to blue light can be compared to gas being in the pump but not getting into the car,“ said Giebultowicz. “Another troubling discovery was that molecules responsible for communication between neurons, such as glutamate, are at the lower level after blue light exposure.“

These specific metabolites – essential chemicals for cells to work correctly – have the same function in humans, so if you are looking at good anti-aging strategies, avoiding excessive blue light exposure is a simple but powerful idea. 

Artificial Blue Light Is Detrimental to Cell Function

Blue light given off over long periods at short distances from electronic screens could meddle with normal cellular processes and disrupt our natural circadian rhythms.

Blue light from everyday devices, such as TVs, laptops and phones, has been observed to produce detrimental effects on practically every type of cell in our body, from skin and fat cells, to sensory neurons. 

These days you’ll notice plenty of skincare companies claiming their products can protect you from the effects of blue light. They probably don’t; blue light can activate genes associated with inflammation and photoaging (skin damage) and typical sunscreens do not block high-energy blue and visible light damage.

Most of Us Are Living in a Pervasive Blue Light Environment

If you’re not using your devices much and spending most of your time outdoors, where your cells are synced with the natural circadian rhythms of the Sun, you probably don’t have much to worry about in terms of whether your lifespan is getting cut shorter and shorter.

But if you’re like most folk, you’re living and working under LEDs, using screen devices, and spending most of your time indoors. Screens are everywhere, and people worldwide already spend an average of 6 hours and 37 minutes looking at them daily.

(Note that this is far more than the 2 hours limit recommended by The recommended screen time worldwide is 2 hours a day for adults and children.

80% of American adults who use digital devices do so more than two hours per day (according to the Vision Council). Nearly 67% use two or more devices at the same time. Fifty-nine percent have symptoms of digital eye strain, which is a marker for high oxidative stress in your retinal cells.

If you hadn't thought about blue light and its effect on your life before, perhaps now you can picture how living under the wrong type of light can literally cut your lifespan short.

STUDY: Flame Retardants Linked to Lower IQs, Hyperactivity in Children

Polybrominated diphenyl ether, PBDE, flame retardants are now a world-wide pollution problem reaching even remote areas. But the most common exposure is more personal that you might think. It is most commonly found at home in household products, furniture, and even clothing.

Research is finding that exposure in the womb to fire-beating chemicals in furniture and carpet pads may hinder child development. One new study found that spikes in the levels of one class of flame retardant, polybrominated diphenyl ethers (PBDEs) is correlated with behavior and cognition difficulties during early childhood.

What are behavior and cognition difficulties?

First, let’s clarify this catch-all term that is becoming a catchphase in many childhood issues.

Behavior and cognition difficulties can refer to any behaviours that create problems with social interactions, such as: disorders of attachment, disruptive behavior disorders, attention-deficit/hyperactivity disorder (ADHD), anxiety and mood disorders, and disorders of self-regulation of sleep and feeding in children younger than 6 years.

When children have such difficulties, it can greatly interfere with not only how they play and interact with others, but also harm parent–child relationships, physical safety, their ability to participate in child care, and school readiness at later ages.

It is a huge concern because these cognitive behaviours are linked to measurable abnormalities in brain functioning and persistent emotional and behavioral problems.

The study

Researchers investigating the health impacts of prenatal exposure to flame retardants collected blood samples from 309 pregnant women early in their second trimester.

The researchers tracked children through the first five years of their lives, looking at a battery of tests for IQ and behavior. They found that children of mothers who had high PBDE levels during their second trimester showed cognition deficits when the children were five years old as well as higher rates of hyperactivity at ages two to five.

the findings

If the mother’s blood had a 10-fold increase in PBDEs, the average five-year-old had about a four-point IQ deficit.

“A four-point IQ difference in an individual child may not be perceivable in…ordinary life. However, in a population, if many children are affected, the social and economic impact can be huge due to the shift of IQ distribution and productivity,” —lead author Aimin Chen, an assistant professor of environmental health at the University of Cincinnati College of Medicine.

The researchers did not track the children’s PBDE blood levels after they were born, so the deficits could also have resulted, at least in part, from the additional exposures to the chemical that the children encountered directly after they were born. However, although the lack of blood level data in the children is a limitation, other researchers have measured both mother and child PBDE levels and found similar deficits, strengthening his conclusions.

The team also found that association of PBDEs and child IQ and behavior did not result from the mother’s blood levels of lead, a well-known neurotoxic metal.

exposure to flame retardants is linked to lower IQs

The findings are similar to what two recent large U.S. studies found, showing that the greater the prenatal exposure to flame retardants, the greater the developmental deficits and the lower of IQ of the child.

children are most vulnerable

Children are at high risk of encountering this poison because they spend so much time close to the floor and often put their hands in their mouths.

They are also being exposed during critical windows of development in utero and in the early years of childhood. If you mess up development when brain structures or neuropathways are forming there may not be an ability to repair them later on.

Products treated with PBDE are usually not labeled. You can take precautions to reducing exposure by having children wash their hands to diminish dust ingestion, and by replacing old furniture and changing old carpet padding.

Toxic home exposure

Polybrominated diphenyl ether (PBDEs) flame retardant chemicals, used in the manufacture of furniture, infant products, and electronics, are ubiquitous in most.

For example, did you know your infant car seat may contain such hazardous PBDEs?

Unfortunately, the side effect of fire safety regulations mean that many clothing, household products are made to “resist fire”. For example, California’s Technical Bulletin 117 (TB 117)—a fire safety law promulgated in the 1970s requires that furniture, baby, and other household products resist open flame (California Department of Consumer Affairs 2000; Zota et al. 2008). The unintended consequence is that PBDE concentrations in California children are now among the highest measured worldwide (Eskenazi et al. 2011).

Babies all the way through toddlerhood want to explore everything and you’re setting yourself up for a near-impossible task to police what they put into their mouths! The best policy for such environmental toxins is to reduce and eliminate the sources AT HOME as much as you can.

Sneaky Places At Home Hiding Toxic PFAS Forever Chemicals

By now you’ve heard about PFAS chemicals - the “forever chemicals” most notably associated with non-stick cookware. Its also with plastics pollution and endocrine dysfunction.

But PFAS can be found in many common household items and it is linked to many chronic diseases down the line.

If you have infants or toddlers at home, it's especially important to consider the chemicals that could be in your carpet. For example, rugs are a major source of PFAS exposure for little ones who are likely to put their hands in their mouths after touching the material. 

What are PFAS?

Per- and polyfluoroalkyl substances, or PFAS, is a class of thousands of man-made substances that are common in everyday objects. Peer-reviewed studies have linked them to some cancers, decreased fertility, thyroid disease, and developmental delays, among other health issues.  linked to serious health issues like testicular and kidney cancer, liver damage, thyroid disease, and more, are also hiding out in some pretty surprising places in our everyday lives.

Thanks to their super-strong carbon–fluorine (C–F) bonds, PFAS are extremely stable, making them persistent and resistant to degradation.

PFAS last for decades without breaking down, earning them the "forever chemicals" nickname.

Sneaky places at home that hide PFAS

It may be impossible to completely avoid PFAS, but there are a few simple ways to reduce your exposure. By tackling some of the sneaky places they hide:

Wall paint: One study at Duke University last year found PFAS in six of 10 popular paint brands sampled. The study also determined that in some brands there was off-gassing of PFAS, which reduces the overall concentration of the chemical in the paint on the wall, but disperses it into the air, where it can be inhaled.

Food packaging: PFAS were developed in the 1940s to resist heat, grease, stains, and water. That means they've ended up in a lot of food packaging. That includes pizza boxes, microwave popcorn bags, some wrappers, and grease-resistant paper.

A 2019 study found that people had lower PFAS levels in their blood after eating at home, and higher levels after eating fast food or at restaurants.

Nonstick cookware: The coating used in nonstick cookware usually contains PFAS, and they can easily leach into your food at high heat and once the coating gets scratched.

In fact, overheating nonstick cookware at 570°F or higher leads to the release of harmful chemicals that can cause an illness called "Teflon flu," or polymer fume fever.

In makeup: Cosmetics that are smoothing, long-wear, or waterproof are the ones most likely to contain PFAS chemicals. Without it, your mascara would run. It's a good idea to read ingredient labels (look for any ingredients with ‘fluoro’ in the name).

The Green Science Policy Institute keeps a list of PFAS-free products, including cosmetics brands.

In dental floss: for years, dental floss brands have used PFAS chemicals, which is concerning since it’s a product that goes in our mouths! A 2019 study found that women who flossed with Oral-B Glide had higher levels of a specific PFAS chemical in their blood than women who didn’t use that particular floss. Make sure your floss is PFAS-free!

Soft contact lenses: a random sampling of 18 popular brands of soft lenses sent to an Environmental Protection Agency (EPA)-certified lab all tested positive for PFAS, short for per- and polyfluoroalkyl substances.

Menstrual care products: Mamavation and Environmental Health News conducted a study of PFAS in menstrual care products, including tampons, pads, sanitary napkins and period underwear, and found most of them contaminated to one degree or another with the forever chemicals.

Clothing and textiles: One of the ways fabrics become water resistant is by using PFAS chemicals! Jackets, raincoats, backpacks, and other outdoor gear are often treated with these chemicals.

These fabrics shed fibers that can travel through the house as dust, eventually getting ingested or inhaled.

These same chemicals are used in stain-resistant treatments for upholstered furniture, carpeting, and even curtains. There’s no easy way to know if your items have been treated, especially if they’re older. When it comes time to replace them, seek out brands that don’t use PFAS chemicals.

House dust: Those floaters in the air you see are made up of many things, including chemicals breaking down from various household products, including PFAS. One study found that certain PFAS chemicals were detected in 97-100% of samples! One straightforward solution is to keep your house as clean as possible. Use a water-damp cloth to remove dust (referred to as wet dusting), is a simple way to lower PFAS exposure in your home. lingers in the air and allows humans to breathe the chemicals into their lungs or ingest them. By cleaning regularly, along with opening windows to allow for airflow and ventilation, you can keep dust levels low in your home and reduce the amount of PFAS you swallow.

Tap water: Communities located near military bases, such as Newburgh, New York, often find their water supplies contaminated with PFAS. The pollution can also affect local fish populations and the people who eat them.

PFAS levels in community tap water in Massachusetts reveals a trend of increasing contamination, with total fluorinated compounds exhibiting a 5- to 320-fold rise over 25 years.

People living near military bases are more vulnerable to water contamination. For example, it emerged through internal U.S. documents obtained by journalist Jon Mitchell for The Japan Times that accidental leaks of PFOS-containing fire extinguishing foam at Kadena Air Base may be linked to the contamination of drinking water on the island.

Cellphones / Fingerprint-resistant smartphone screens: PFAS are used in pretty much anything to make things more resistant to grease and water. The circuit boards, semiconductors, and insulated wiring that use PFAS, as well as the touch screen, which has PFAS coating to resist fingerprints.

What Are EMFs? 7 Things You Need to Know as a Mother

You probably hear about EMFs and its associated risks in the devices, content, and habits that we have, but what exactly does it mean? And what does it mean if you have children or are planning for a family?

In this article, you’ll learn what is EMFs and how they’re negatively affecting the health of children, in particular concerns around fertility, conception, birth and all through the crucial years of child development.

What are EMFs?

EMFs are invisible and completely beyond most people’s awareness. However, some people can actually feel them. Especially those that are manmade (non-native electromagnetic radiation).

The Electromagnetic Spectrum

The simplest way to understand how important EMFs are to our health – is by learning about the electromagnetic spectrum.

contains the entire range of all electromagnetic radiation. It also shows the field’s approximate frequency – which relates to its wavelength.

At the absolute lowest frequencies in the hertz range, we see the largest wavelengths. These are the size of several thousand miles! The lowest of frequency fields includes the Earth’s Schumann Resonance, which is also very healing for us when we are grounded in Nature to its energy.

The higher in frequency, the field gains more energy, and also reduces in wavelength. (That’s why wireless radiation is often called pulse radiation to describe its very high energy field.) In fact, at the frequency of Wi-Fi, your body is being exposed to 2.4 or 5 billion pulsations per second. Compare that to the natural Schumann Resonance, which has just 8 gentle cycles per second.

EMFs may be triggering your child’s hungries

In healthy participants and compared with no exposure, 50-minute cell phone exposure was associated with increased brain glucose metabolism in the region closest to the antenna. Link to the study: https://jamanetwork.com/journals/jama/fullarticle/645813

Light can cause breast cancer

2008 – Austria – Cell Phone Towers and CancerA study by Austrian Dr. Gerd Oberfeld (EMFacts 2008) showed a 23-fold increase in breast cancer and a 121-fold increase in brain tumors for those who lived with 200 meters of a cell phone base station for five years or longer! http://www.verwaltung.steiermark.at/cms/ziel/21212/DE/

EMFs may be harming your chances of conception

There’s enough compelling evidence to show how higher levels of exposure can reduce sperm quality in men.

It can also increase miscarriage risk in women. Two miscarriage studies, conducted by Kaiser Permanente and funded by the National Institute of Environmental Health Sciences, are particularly interesting because they're some of the only ones to date that actually measured EMF exposure in subjects using a magnetic field monitoring device.

"We took [913 pregnant women] and asked them to wear the monitor for the duration of their pregnancy. Studies right now aren't using the meters because most of them are focusing on cancer. [But] Cancer can take 20 years to develop—you can't measure your exposure from 20 years ago, so in those cases, you just ask how much the person uses their cell phone." — eproductive epidemiologist De-Kun Li, MD, PhD, the principle investigator on both studies (one published in 2002, one published in 2017).

Breast cancer is the most common malignancy among women anywhere you're from. In Singapore,

Researchers looked at how short wavelength visible light in the blue region emitted from digital screens TANKS this crucial process.

also examined different levels of radiofrequency electromagnetic fields (RF-EMFs) such as cellular phones (29-40), mobile base stations(41, 42), Wi-Fi routers

We have shown that both the blue light and RF-EMFs generated by mobile phones are linked to the disruption of the circadian rhythm in people who use their phones at night.

women who carry mutated BRCA1 or BRCA2, or women with family history of breast cancer should avoid using their smartphones, tablets and laptops at night.

Why bother with a sleep sanctuary if any will do?

Protecting your sleep/wake cycle is paramount to prevent cancer. Melatonin, the hormone dominant at night, is your ANTI-CANCER hormone. "has been shown to produce strong anti-cancer actions and also promotes sleep."

All mice were kept in the light for 12 hours each day. One group of three mice was in the dark the other 12 hours, which helped them produce high levels of endogenous melatonin. Another group spent 12 hours in light followed by 12 hours in dim light at night, which suppresses their nocturnal melatonin production. The dim light was 0.2 lux, which is less than a night-light or a display light from a cell phone

And the number disruptive to your

Women are more sensitive to melatonin disruptions.

Children are especially susceptible

Children are more vulnerable than adults to the effects of EMF (electromagnetic frequencies or fields) for a number of reasons, and most are submerged in an electrosmog soup all day, every day. What are the risks?

In 2016, the National Toxicology Program released the results from the largest cell phone study ever performed on the link between nonionizing radiation and cancer. Rats exposed to the frequency of radiation emitted by cell phones developed two kinds of tumors: gliomas in the brain and schwannomas in the heart. These results align with several observational studies finding links to the same types of tumors in humans - plus acoustic neuromas and meningiomas.

• Sleep deprivation

• Low energy, “brain fog”, mommy brain

• Mood issues, such as anxiety, depression, aggression and impulsivity

• Increased stress

• Affect sleep/wake cycles in babies through breastfeeding

• Developmental issues (especially in young kids)

• Dry-eye disease

• Decreased hand-eye coordination

• Reduced ability to form social connections and relationships

• Reduced executive function

In 2010, Powe et al. reported that among 25 Boston-area women,  mothers of sons produced ~25% higher energy density in milk than mothers of daughters. More recently, Fujita and colleagues (2012) revealed sex-biases in the milk fat concentration among 72 women in rural Kenya. On average, mothers of sons produced significantly higher fat concentrations in milk.

Children are also sensitive to their environment

Some people are "exquisitely sensitive" to places where EMFs are present. Some literally cannot be in certain places because of the Wi-Fi there—they end up with fatigue and headaches and ringing in the ears and a sense of brain fog to the extent that it may affect thinking and speech patterns.

I had a glimpse of this as a child that worsened as a teenager until it hit a peak when I was working fulltime. It took me until I was into my 30s to understand where all these symptoms were coming from.

The thing is, at that time I had no idea what was going and kept going, kept struggling despite the bouts of malaise that would hit me. It takes time for children to learn how to express their bodily aches in calm ways for our adult ways; before then, it often manifests as temper tantrums, general fatigue and “laziness”, and spectrum-type disorders.

What Makes a Safe Light Bulb – The Definitive Guide

Have you ever thought about whether your light bulbs are safe or giving off EMF radiation?

Newer light bulbs that have been developed to be more energy efficient, are actually some of the worst offenders.

Lighting are a big part of indoor spaces, and probably one of the biggest investments you can when you are renovate or making a brand new home. It takes time, energy, and money to decide exactly how you light up your indoor space — and it creates the light environment that you’re going to live in day after day.

Because you turn these on at night, extending your “daylight” hours, the type of light bulb you choose to fit your home in determines the quality of your environment.

Brief history of light bulbs

Thomas Edison is credited with inventing the first light bulb in 1878. They relied on the heat generated by a tungsten wire contained in a glass bulb and were called incandescent light bulbs. They are simple, and also generated heat, which can be useful in cooler climates.

As energy-efficiency considerations arose, however, the U.S. Department of Energy (DOE) recognised that energy efficient alternatives needed to be made readily available and become the new standard for Americans. It, along with other governments, looked for ways to reduce energy use en masse.

The aim was to accelerate America’s shift from inefficient, dated lighting products to innovative, high-performance products that can save American consumers and business owners money.[r]

On 3 August 2011, the DOE officially announced Philips Electronics North America as the first winner of the L Prize competition with an LED replacement for the 60-watt incandescent bulb.

The $10 million U.S. government prize marked the first government-sponsored technology competition designed to challenge lighting manufacturers to develop high-quality, ultra-efficient solid-state lighting products to replace the common light bulb with energy-saving lighting alternatives.

Philips turned out to be the only official entrant in the competition and the LED bulb retails at $40, far more than people are used to paying for a light bulb. Government support would be crucial to help the LED be competitive in the market. [r]

So this was a big deal. With the backing of government policies and commitment by other governments in the world, traditional light bulbs began to be replaced by a new technology — the light-emitting diode, or LED.

The LED light bulb

the increasingly popular LED bulbs. LED or Light-Emitting Diode bulbs rely on (you guessed it) a diode to produce light. The diode controls the direction of the energy flow. They are illuminated solely by the movement of electrons within a semiconductor material.

An LED contains blue light, a driver, and a fluorescent sheet that covers the blue light by extending the wavelengths producing a more yellowish or orange light. In this way, it is similar to a type of fluorescent light; it can fool your brain into thinking it is a more natural light but does not protect you from the dangers of blue light exposure, especially at night.

There are two primary dangers when it comes to LED light bulbs:

• Exposure to blue light

• Creation of drty electricity (a form of negative EMF) and electromagnetic radiation

The health impact of LEDs

However, research around the health impact of a new lighting technology emerged.

blue light from sources like your phone, laptop, and LED bulbs suppresses melatonin production, the hormone responsible for regulating quality sleep and wakefulness.

Blue light can also induce headaches and migraines, worsening any pain symptoms that you have. It results in eye pain and fatigue, which was commonly called in the 1980s and 1990s as “computer vision syndrome”.

There are countless clinical studies that support the harmful effects of blue light especially for people who prone to headaches or migraine attacks. Researchers have suggested that there is a specific neural pathway from the eyes to the brain—separate from how vision is transmitted—that ultimately causes blue light wavelengths to worsen headache pain and other symptoms.

Some researchers suggest it is the specific wavelength, in and around 480nm, that leads to high discomfort. It creates a pain perception and even enhanced spreading of headache pain across the brain.

Finally, blue light from LEDs can damage your retina.

• Are you living in junk light?

• Study shows light at night increases your risk of type 2 diabetes

• Blue light can cause precocious puberty

CFL Light Bulbs

As mentioned, LEDs are similar to CFL or Compact Fluorescent Light bulbs.

These are even more dangerous, probably the least safe light bulb on the market today. This is because the CFL use an electric current driven through a tube typically containing mercury vapor.

ALL fluorescent light bulbs contain mercury vapor, which emits a lot of UV rays when hit with an electric current. Increased absorption of such UV radiation from CFLs has been linked to a variety of health effects and skin disorders.

One key study showing this direct cause is from 2012 study. Researchers from the State University of New York at Stony Brook showed in a paper that tiny defects in the bulbs can let through UV light that can damage skin cells and lead to cancer. Not one CFL bulb they studied did not have any cracks or defects in the phospor coatings. This meant the bulbs emitted very significant levels of UVC and UVA.

The energy efficient compact fluorescent lights that are commercially available generate radio frequency radiation and ultraviolet radiation, they contain mercury—a known neurotoxin, and they are making some people ill. Instead of promoting these light bulbs governments around the world should be insisting that manufacturers produce light bulbs that are electromagnetically clean and contain no toxic chemicals. — Dr Magda Havas, an expert of EMF radiation, www.weepinitiative.org/LINKEDDOCS/scientific/08_Havas_CFL_SCENIHR.pdf

Last but not least, CFLS produce dirty electricity in your whole-house circuits. Just like LED bulbs, the circuits are not equipped to handle the demand of CFLs, which leads to dirty electricity. This dirty electricity builds up in the wiring of our home flooding it with EMF radiation.

Many people still purchase CFL bulbs for the same reason of energy efficiency and cost. CFL bulbs can provide the same amount of lumens as incandescent light bulbs, using about one quarter of the energy.

incandescent light bulb

To appreciate the difference in lighting, let’s go back to understand what was traditionally used.

60-watt incandescent light bulb is one of the most widely used types of light bulbs by consumers, representing approximately 50% of the domestic incandescent light bulb market.

Although incandescents may not be the most energy-efficient, the safest available lightbulb is the traditional incandescent.

halogen light bulbs

A halogen light bulb is a type of incandescent lamp which uses a halogen gas in order to increase both light output and rated life. These are popular for its moderately high efficiency, quality of light, and high rated life compared to regular incandescent lamps.

How Can You choose the safest light bulb?

Light bulbs are not as innocuous as you might think.

If you have to be indoors and needing light, you don’t want to remain the in dark and shun all lighting sources, including light bulbs, because that can have physical and emotional consequences too.

So what are your options? Try this quick checklist to choose the safest and best light bulb you can and minimize the damaging effects of bad lighting:

• Buy and use traditional incandescent or halogen bulbs. These use traditional heat source to produce a natural warm glow of light.

• If you choose LEDs, choose a warmer-coloured LED bulb. LED-makers are realising the health impacts of too-blue LEDs and racing to come up with warmer-looking alternatives.

• If you have LEDs at home, install them in low-traffic zones. This means you reduce your exposure to toxic LED light, such as walkways, instead of overhead in bedrooms or where you work.

• In high-traffic zones and for light-sensitive tasks (such as sleep), use incandescent or halogen light bulbs. They may not be the most energy efficient, but they will help to reduce the amount of EMF radiation emitted in the spaces that you occupy.     

• Try "blue blocker" or blue-light filtering glasses, but don’t settle for cheap knock offs. TheraSpecs are a great brand, particularly if you already have migraine or another light-sensitive condition.

• Use "night mode" or similar apps that are native settings on your phone and your computer. This can warm the lighting on your device and make it easier on the eyes.

• Turn your phone or computer off at least 2-3 hours before you go to bed.

• Change your light bulbs to warmer tones and colors. Opt for more natural light if possible and avoid/remove fluorescents, if appropriate.

• Give your eyes a break. Look away from your screen at least once every 20 minutes to let your eyes reset. And don’t forget to blink!

• If you must work under an LED, position your desk so that you are next to an open window (at least a crack) and your body can receive full-spectrum light energy. And you can take eye breaks looking out an open window. This is a building biology hack!

the study

The researchers looked at 1134 mother-child pairs from 6 European countries (France, Greece, Lithuania, Norway, Spain, and the UK), and their prenatal exposures to common endocrine-disrupting chemicals (EDCs) mixtures. The mean age of the mothers at the birth of their child was 30.7 years, and they were recuited into the study April 1, 2003, and January 30, 2009.

These common toxic chemicals included “metals, organochlorine pesticides, polybrominated diphenyl ethers [that’s PBDEs, or flame retardants], and perfluoroalkyl substances”.

They then measured the children born to the mothers at 6 to 11 years of age. They focused on markers of metabolic syndrome, which combines measurements of blood sugars, lipids such as cholesterol, the existence of fat tissue and the impact on the heart.

We almost always consider health risks from single chemicals, one at a time, as if we are exposed to just one chemical at a time. Here the research team shows that children’s risk for cardiovascular disease and diabetes later in life can be driven by the complex mixtures of endocrine-disrupting chemicals in the body at any moment and it highlights the particular risk of chemical exposures during pregnancy. —Jane Houlihan, the national director of science and health for Healthy Babies Bright Futures

what the researchers found

They found that the exposure to toxins were associated with increased metabolic syndrome risk score and altered proinflammatory proteins, amino acids, and glycerophospholipid levels in childhood.

The childrens’ comprehensive tests had elevated levels of metabolic syndrome at ages 6 to 11. Metabolic syndrome can include obesity, elevated blood pressure, and abnormally high cholesterol and insulin resistance, which is a precursor to type 2 diabetes.

Within the group of children exposed to the highest levels of chemicals, 62% were overweight or obese, compared with 16% of children within the low-risk group.

Moreover, the levels of blood insulin and triglycerides, as well as systolic and diastolic blood pressure, were significantly higher in the high-risk group than in the low-risk group.

Pregnancy and childhood are especially important times to limit exposure to chemicals as the brain and body are in key stages of development. Sign up for a free guide to common pollutants AT HOME that you can reduce now.
