5 Reasons Why Blue Light Is Bad For You And How To Avoid It
Our environment has changed more in the last 50 years than ever before, which brings us a set of issues we never had before. One of them is exposure to nnEMFs (non-native electromagnetic fields) such as blue light.
Even though it's still a controversial topic, a growing body of evidence indicates that nnEMF’s are damaging to our health.
Many know that blue light emanating from the screens of our beloved devices can mess up our sleep cycle, but few know how it might cause damage on a cellular level as well.
In this blog, I’ll share 5 reasons why blue light is bad for you and what can you do to avoid it.
1. Blue light dehydrates our cells and affects our affects our mitochondrial health
First, let’s make one thing clear: there’s natural blue light and artificial blue light - not both of them are bad for you. Natural blue light (from sunlight) is actually good for you and keeps you alert and awake!
The reason why artificial blue light is bad is because it’s not balanced by the red like sunlight. It uses an unnatural spectrum of light that our bodies are simply not designed to.
Neurosurgeon Jack Kruse believes this unnatural blue light is one of the biggest health issues right now. He believes that the explosion of chronic disease within the last few centuries is directly linked to moving from outdoors society to indoors society and being exposed to nnEMfs.
He suggests that all nnEMFs, including blue light, decreases the amount of water and CO2 a mitochondrion makes. This leads to chronic dehydration and ties into poor mitochondrial health and mitochondrial heteroplasmy.
Mitochondria is the powerhouse of our cell - where the food transfers into energy.
Simply put, blue light causes mitochondrial damage that disrupts this process and starves the cell of energy - which then leads to a range of diseases.
2. Blue light induces cellular dysfunction and free radical production
A study published by Journal of Biological Chemistry came to a similar conclusion. It discovered that blue light exposure caused mitochondrial dysfunction primarily via increased ROS (reactive oxative species.)
ROS are free radicals that wreak havoc in our cells and cause premature aging.
The study suggests that tissues such as skin and eye, which are regularly exposed to blue light, are the most vulnerable to dysfunction.
3. Blue light messes up our circadian rhythm and disrupts our sleep
Blue light from sun signals your body that its morning and it makes us alert and awake. But what happens when it’s night and you’re watching Netflix on your laptop? Same thing! Your screen is literally screaming to your brain “WAKE UP!”
When it’s dark and time to go to sleep, our bodies naturally start secreting melatonin. But if you start scrolling on your phone or watching TV… melatonin gets suppressed.
An as melatonin secretion is disrupted, it disrupts our circadian rhythm which has a domino effect that can cause other disturbances as well.
Circadian rhythm is our biological clock that helps to prepare our bodies for the fluctuations of the day.
4. NnEMFs (including blue light) may cause infertility
The fertility rates are dropping and a growing body of evidence suggests that nnEMF’s may play a role in it.
Study of male fertility from 2018 reveals that exposure to cell phones, microwave ovens, laptops, or Wi-Fi produces deleterious effects on the testes, which may affect sperm count, morphology, motility, an increased DNA damage, causing micronuclei formation and genomic instability, as well as disruptions in protein kinases, hormones and antioxidative enzymes. These effects were found to cause infertility due to an over-production of ROS (free radicals) in exposed cells.
Unfortunately women aren’t safe from EMFs either. Studies have shown that electromagnetic fields can have destructive effects on sex hormones, gonadal function, fetal development, and pregnancy.
5. Blue light stresses our eyes and may cause permanent eye damage
Digital eyestrain is a common problem for those working on computers all day.
I'm sure we have all experienced the symptoms after a long day at behind the screen : blurry vision, difficulty focusing, dry and irritated eyes, headaches, neck and back pain.
Some research suggests that blue light exposure may not just cause irritation, but permanent eye damage as well. Excessive blue light exposure may contribute to the destruction of the cells in the center of the retina; and play a role in causing age-related macular degeneration, which can lead to vision loss.
How To Avoid Blue Light
More extensive research about the dangers of nnEMFs is needed, but until then it’s probably better to be safe than sorry and minimize your exposure.
Here’s few ways to avoid blue light:
How to reduce the harmful effects of artificial blue light and other nnEMFs?
I know that there's many people like myself who work on their computers and getting rid of all electronic devices simply isn't an option. Luckily, there are many things you can do to reduce the harmful effects:
Exposure to sunlight can restore your mitochondrial health so get as much natural sunlight as you can during the day. Your mitochondrial energy balance is best when you’re in Nature.
Grounding (being in touch with earth’s electromagnetic field) by walking outside barefoot or using grounding blankets can reduce inflammation and strengthen your immune system.
Balance your circadian rhythm by going outside in the sunlight as soon as you wake up, avoid watching any screens and limit artificial light in the evening. Keep your bedroom dark, use blackout curtains to optimize your melatonin production.
Minimize the nnEMF exposure by keeping all your devices in another room where you sleep. Use airplane mode on your phone when possible and never let your wireless devices directly touch your skin (such as keeping your phone in your bra).
Use a modem instead of Wi-Fi for your internet, and always use a device with a chord rather than wireless.
In the end, it's all pretty simple. You were designed to live under the sunlight instead of artificial light, be nourished by food that grows in the Nature instead of factories and to communicate in person instead of devices.
If you live under artificial lights, eat highly processed foods and can't get your eyes off the screen, it's going have an impact on you.
The same rule applies to every aspect of our health. The further we go from Nature, the sicker we get. Luckily, the remedy is simple, as long as we protect Nature from pollution and other damages.
