Dr. Jack Kruse: Blue-blocking glasses, and much much else

[RunningDeer]

Condensed version from “Junk Light, 5G, Optimizing Sunlight and Longevity”. (full transcript and video here.)

Light is like a medicine, and a lot of people don’t realize that, but that’s actually what it is. And if you look at what sunlight looks like, and you think about what all parents for the last 75 years have been told by centralized healthcare is that the sun is toxic, and you need to put sunscreen on kids and keep them out of the sun. It completely goes against our evolutionary directive.


There’s hardcore data out there. Like, there’s been six meta-analyses in the literature. The last one happened in 2016 in Sweden, and it basically said that lack of sunlight is more dangerous to your health than smoking cigarettes.


When you think about the flip side of this, that the kids today have grown up in a world where everything is blue-lit, like blue-lit screens, digital babysitting, iPhone, iPad. If you put a spectroscope on that technology screen, you would not like what you see.

And we now know the science is well-developed that blue light causes breakdown in the retina. The breakdown in the retina leads to changes not only in the retina, but also in the brain. When I was a kid, we never had school shootings or kids killing themselves.. Today it’s an epidemic.

What many of you may not know is that that’s directly related to the amount of screen time. And the reason for that is blue light destroys dopamine levels. And dopamine is a chemical. It’s most widely associated with Parkinson’s disease, but that’s not the key thing. If you go and look at addictive behaviors or depression, it’s also associated with those. And the reason for that, in the pathway of your eye, you have a clock called the suprachiasmatic nucleus. And we now know that those neurons stop at a place in the brainstem called the habenular nucleus. The habenular nucleus in that part of your hypothalamus actually controls your mood.

Children are much more sensitive to non-native EMF or fake light because their brains aren’t fully myelinated. That’s the reason why children can’t rent cars or hotel rooms because their frontal lobes are not even myelinated.

The flip side of that argument is they’re much more sensitive to these frequencies, and parenting has changed so much in the last 30 years that people think it’s okay to give a kid an iPhone.

So, when you add these two parts of the coin together, too much artificial light, at night, and no sun during the day, you set these kids up for an absolute train wreck in terms of their health. And we now know that children compared to years past aren’t as healthy as they used to be. I mean, there’s a lot of other things that go into this, but is that the underlying theme? It is.

Dr. Kruse: Well, the number one thing, sunlight is a multifactorial thing. Think about a barrel of oil. Most people know that a barrel of oil has to go to a refinery, and it gets processed, and it becomes 60 different things that we use in industry, like lubrication, gasoline, kerosene, all different kinds of things.

Your mitochondria in your body do the same thing with light. So, I don’t want you to think this is just about blue light, or purple light, or orange light, or red light. There’s consequences to how light is refined in your body. And when the dominant life force, or I should say light force that your children are seeing are artificial manmade light, they’re not able to refine things in them.

Like, you mentioned a couple of them already, melatonin and the problem that they have with hormones. It’s a huge issue. And the problem is you need to understand how those things occur. We’re designed to refine that light. Now, if you understand the mitochondrial biology, there’s two main portions of the spectrum of light, purple and red light. They’re on opposite ends of the rainbow, usually UV and infrared-A. And those two forms of light are really important for us because they control the two change programs in our mitochondria which recycle our energy.

Why is this a big deal? Most people have been told that melatonin is predominantly made in your brain and in the pineal gland. Not true. 95% of melatonin is made at your mitochondria. And the reason for that is melatonin controls apoptosis and autophagy, which are the two change programs.

Well, it turns out apoptosis is controlled by purple, which is UV light, UVA and UVB. And autophagy, which is the recycling of mitochondria, is controlled by the red light. So, when you go and put sunscreen on your kid, what effectively are you doing? You’re blocking just about all of their ability to do things with the purple part of the spectrum. You’re not affecting a lot of other parts, but you’re affecting that one.


So, what’s the major effect? It inhibits the child’s ability to make vitamin D. And when you can’t make vitamin D, what does vitamin D do? A thousand genes get turned off. What’s the single most important? Well, it turns off T regulator cells. That means your immune system is totally jacked up. People who get skin cancers, what’s the number one link is ow vitamin D levels go with melanoma. So, if the sun is the cause of melanoma, explain to us why everybody that’s got melanoma has got a low vitamin D count? It turns out a lack of sunlight leads to skin cancer. And when you really examine it, you’ll find out that too much blue light, not enough red and not enough purple, is the real answer of how that light is refined in our body to wind up with the cancers that, your trying to protect from.


So, I would tell everybody whether it’s sunglasses, clothing, sunscreen, do what wild animals do. When you’ve had enough sun, go under a tree, go under an umbrella. The papers that are out for the last 20 years totally disagree with that. The problem is sunscreen, for example, it’s a $7 billion business. They’re not gonna tell you the difference because that $7 billion goes away. So, you have to be an informed consumer.

[RunningDeer]

You have to ask yourself, "What are you willing to do to offset your risks?" Now, some people may say, “I’m willing to do some, but I’m not willing to do it all.” That’s fine. I think any step in the direction of wellness in decentralized nature is a good step. ~ Dr. Kruse

.....

.....

Condensed version from “Junk Light, 5G, Optimizing Sunlight and Longevity”. (full transcript and video here.)

Dr. Kruse: Non-native EMF, technically, just to define it, is everything outside the visible spectrum. Most people know that terrestrial sunlight from our sun is 250 to 760 nanometer light. Everything else in the electromagnetic spectrum is garbage, which we call non-native EMF.

We are not designed to operate within it. So, for example, in the visible spectrum, we just talk about blue light. Blue light subtracted from the rest of terrestrial sunlight, technically, is non-native EMF. Why? Because you’re not designed to get blue without the purple and the red. So, that’s fixable there. And that’s probably the number one non-native EMF out there.


These days, you’re correct, Wi-Fi, 3G, 4G, 5G, big deal. For parents to pay attention to this, just read the NTP toxicity report done by the federal government where they irradiated nocturnal mammals, I should say mice and rats, for a period of time with just 2G and 3G phones. The animals all got tumors and cancer.

So, it’s not like we don’t know that this happens. And when you wanna jump down the rabbit hole further, then I would tell you to go read a book called “Going Somewhere” by Dr. Andrew Marina. He’s a physicist and a lawyer. He’s actually been testifying about this to Congress since 1977. His testimony began when he showed that the power grid in New York state that went from New York City up to Niagara Falls changed the earth’s magnetic field 80,000 kilometers in space. So, for people who don’t think that we have the data, just remember the year was 1977, and the books and the data is out there.


The same for with sunscreen, $7 billion industry, non-native EMF, probably $4 trillion, $5 trillion industry. So, there’s a reason that you don’t get told the truth. The reason why is because they want you to be an obedient idiot so that you’re in their paradigm so they can keep harvesting. And the problem that a lot of people make, especially parents, “Well, these kids do it, or this family does it, or we all do it.” And the problem is this is part of the reason why we’re all much sicker, where in cities, especially, our longevity’s been going down for the last five or six years.

So, you have to ask yourself, what are you willing to do to offset your risks? Now, some people may say, “I’m willing to do some, but I’m not willing to do it all.” That’s fine. I think any step in the direction of wellness in decentralized nature is a good step. I just want people to know that this data, it’s not wacky, it’s not quacky, it’s well-published in great journals.

The problem is it’s been blocked from you. The reason a lot of people don’t know about this is because industry who’s been printing money, selling you this stuff, and causing you problems, it’s a big issue.


[RunningDeer]

But here’s the real caveat. If your body makes it endogenously, you should never take it exogenously. ~ Dr. Jack Kruse

Condensed version from “Junk Light, 5G, Optimizing Sunlight and Longevity”. (full transcript and video here.)

Katie: Yeah, I think that alone is such a paradigm shift… It’s like we keep looking for these complicated answers when the answers have always been in front of us through nature. You mentioned vitamin D. I think that might drive a lot of people to just start wanting to supplement lots of vitamin D to try to fix these problems. And I know you have wisdom around that. So, I’d love to touch on vitamin D and omega-3s.


Dr. Kruse: Yeah. I would tell you, let’s give the disclaimer, because I think when a lot of people listen to my podcast or they eat stuff or they follow me on social media, you hear that I don’t like to talk about food, and I’m not really big into talking about exercise.

It’s not really true. I want people to understand light is by far the most important. When it comes to supplements, same reason. I told you before, supplements are basically fake Frankenfoods that you’re adding to the mix. But here’s the real caveat. If your body makes it endogenously, you should never take it exogenously. Why? It has to do with something called predator and prey. Remember I just told you the story about decentralized light and dark? So, let me give you an example. One that we used earlier today.


If you give your kids melatonin to help them sleep, it’s because their mitochondria don’t make it. When you give the kid melatonin long enough, you down-regulate the melatonin production that they make in their own mitochondria. So, you’re turning off the machinery because you’re getting an exogenous signal. So, it ultimately makes your kid worse.

What’s some of the effects that can happen to a child down the road? They can thin their retina, they can get retinal tears, they can develop really big problems with their central retinal pathways. Why? Because it turns out melatonin and dopamine regenerate all the photoreceptors in your eye. Does the pediatrician ever tell you that? No. Because they’re looking to give you the centralized answer to get you out of their office in 10 minutes, and that’s it, you know, for your $25 copay. If you do your own homework, you’ll find that those answers are out there.

Melatonin is made in the mitochondria. So, supplementing that is a big no-no. Vitamin D, the same way. Vitamin D is made endogenously in our skin. But vitamin D is a very interesting vitamin because it’s not a vitamin, it’s a neurosteroid. And vitamin D, one of the things that it does is it gets created in the skin from cholesterol and 312 nanometer light, which is UVB light. It changes the double bond in a ring in cholesterol to turn it into something called 25-dihydroxyvitamin D. That’s not the key factor. It has to go to the kidney and liver then to be converted to 125. So, can you have a problem with vitamin D that starts on the skin, or could you have a problem if the kid has a problem with their liver or their kidney? The answer is yes. A lot of times, this never gets worked out. The most common reason for children why it’s a problem is their skin is blocked from clothing or sunscreen.

The reason why this is a big deal in adults, is if you look at your blood work and you notice when they do a lipid profile on you, that your cholesterol level’s going up, I can almost guarantee you what their answer is. They’re gonna tell you they want you to be on a statin. I’m gonna tell you, you need to be in the sun more, because high cholesterol levels chronically over time is almost always associated with low vitamin D levels because you’re not converting cholesterol into vitamin D.


Katie: Yeah, I think that’s such an important thing to understand. What about omega-3s, though? Because I feel like this is an area where there’s a lot of controversy, especially right now about if they are good, if they’re bad, if they’re rancid, if we should avoid them, if we should take them. What’s your take on that?


Dr. Kruse: You’re designed to get omega-3s from the marine seafood chain. Supplementing it, I’m not a fan of. And the reason why, most people need to understand that exogenous pills are polyunsaturated fat, that’s what DHA is. You have to realize how this works in an evolutionary standpoint. DHA is the only lipid in mammals that hasn’t changed in 650 million years.

In other words, there’s something specific about this chemical that is highly favorable to complex life. And most people don’t realize this. DHA, you know where the number one place that it’s found? Your central retinal pathways right in front of your eye clock. So, what’s the biophysics of DHA? Twenty-two carbons double-bonded that creates a pie electron cloud. Effectively what it is, it’s a copper wire that connects your retina to the suprachiasmatic nucleus, then to the hypothalamus.

So, remember all the things that we talked about, about refining the barrel of oil for your children? Well, if you don’t have good copper wires in your refinery, how do you think you’re gonna do? Not very good at all, right? So, that’s fundamentally what the problem is. Seafood is the best way for you to get it. Now, how you get it from seafood, that’s completely up to you. I would tell you use locally sourced stuff if you can. If you live in a place that doesn’t have it, that becomes much more difficult. But I’d much rather you eat the real food than the supplement.


Katie: Are there any, for you personally, exceptions to that or things the body doesn’t make that you would consider taking in a supplemental form, or do you stick to food and these other factors we’ve already talked about?


Dr. Kruse: Well, when I’m taking care of people, you know, on an acute basis, there may be things that I recommend on two or three-week period of time that I wouldn’t on a chronic basis. Like, if you’re trying to get over certain things, like for example during COVID when I told people, “Look, these are some of the things that you can do. These are things that would get you by for two, three, four months so you didn’t have to worry about COVID if you were not going outside.”

But I would always tell people, “If you go outside, raise your vitamin D level up, you improve your immune system.” Your immune system technically is your best protection. So, anything you can do to improve that standpoint.


Now, there’re certain people, like, remember most people that come to see me, their physiology is already trashed, they’ve already got diseases, so you’re trying to ramp them up and get them better. So, everybody’s unequal as one is different. And when somebody comes to see me, generally, it’s because their mitochondria is already screwed. So, the things that I’m always gonna recommend/teach is how to use purple and red light to re-innovate their bad mitochondria. But I may add certain things in if it shows that that problem exists. I would say maybe 50% of the time, that’s actually the case, but most people, once you get them through their acute issue, you don’t need to have any supplements.

Re: Contact Lenses | Prescription Glasses

Don’t wear them when you’re soaking up sun.
It’s like the open window VS closed window.

UPDATE: November 20, 2024

I’m about half way through the video provided by ClearWater: “Sunlight: Optimize Health and Immunity (Light Therapy and Melatonin)". The format is ideal with Q&A, diagrams and bullet point slides and summaries along the way.

Before too much time passed, I want to update or add to the earlier information from Dr. Jack Kruse. He stated not to wear sunglasses, prescription glasses or contacts while soaking in the natural sunlight. It was to an interviewer that wore prescription glasses.

I’ve listened to about 7-9 other speakers and none of them brought up the topic. Whereas, Dr. Roger Seheult says and posted a slide: “Glasses/contacts do not interfere”.

Yeah, thank you Running Dear!
And agreed, I would really like to have his material in text form.
Maybe somebody could do us an audio to text conversion of the podcasts for the library.
I wouldnt know how to do that.

[RunningDeer]

A few take aways from Dr. Jack’s info.

• Natural daylight signals the brain to produce serotonin which is then converted into melatonin (sleep hormone) at night (in the absence of blue light). If you don't get enough sunlight each day, your serotonin levels won’t reach optimal levels which in turn results in diminished levels of melatonin at night.
  ....
• If your skin is still being exposed to the artificial light in the home from over head LED lighting, high amounts of blue (and green) light hitting it at night can also disrupt sleep and circadian rhythms.
  ....
• Stop eating 3-5 hours before bed. This prepares the body. If you eat too close to bedtime, your body utilizes high amounts of energy digesting food, preventing your body from entering a deep, restful sleep.
  ....
• Blue light destroys dopamine reward tracks in brain. Sleep provides natural dopamine. Dopamine deficient means one must artificially create it. AND the bad guys assist through blue light tech this dopamine addictions for the negative rushes. (ex. no attention span, rage, abuse)

....

Internet info for dopamine imbalances:

Addictions can cause physical and psychological problems, as well as interpersonal problems. Signs of addiction include cravings, intolerance, and withdrawal. 

Addictions can be physical or behavioral: 

• Physical addictions- These include addictions to substances like alcohol, tobacco, opioids, prescription drugs, cocaine, marijuana, amphetamines, hallucinogens, inhalants, and PCP. 

  ....
• Behavioral addictions 
- These include addictions to activities like gambling, eating, exercising, shopping, shoplifting, having sex, viewing pornography, video gaming, work addiction, exercise addiction, and spiritual obsession. 

  ....
• Online shopping addiction 
- Also known as compulsive buying disorder, this is a behavioral addiction that involves impulsive and compulsive buying of goods and services online.

Thank you, leavesoftrees & meat suit. I agree with your points. I’ve had to listen to a lot of vids and cross reference the chemistry and biology vocabulary for it to sink in. Some of the vocab doesn’t stick so much, so there’s a lot of time spent with review. (ex: Noether's theorem, POMC, ACTH binds to melanocortin 2 receptor (MC2R)) I’m a couple of months into this info. A lot of it is finally coming together. I’m glad I stuck it out. The improved sleep and the lingering effects of watching the morning sun is a BIG win! Brainstorming ideas/solutions around my place come easier. Maybe I’m even a bit more intuitive? (to early to say…)

The health aspects are the most important for me. I’m okay with the general premises like:

• Sun is food
• block the negative (artificial) blue light spectrum
• blue light tech destroys dopamine hence poor sleep and creates/feeds addictive behaviors
• the sun produces serotonin which in turn coverts into melatonin for quality sleep

While I'm here, I'll add the summary to your video

Thank you so much for all your keypoints, summaries and infos you've gathered here! I had watched Dr. Kruse's interview on the Danny Jones podcast and wanted to learn more about red lights but then got overwhelmed by the information (and misinformation) out there. Your notes here help a lot!

I wondered why he has suddenly emerged.

I hadn't heard of him either until Clif High highly recommended his Danny Jones interview a few weeks ago. Could Clif have sparked this "Kruse-revival"? 😄

Oh! thank you, QueenRia.

I enjoyed that Danny Jones interview: “Exiled Brain Surgeon: DARPA Mind Control, Quantum Biology & Sunlight Medicine”
It's a fitting title for a 4+ hour vid, and that’s with a section cut out for Patreon customers.

I appreciate it when the host provides a timeline with active links. I download those monster long videos and watch over a couple of days.

Generally speaking, Dr. Jack finds a way to bring in new material and covers a bit of the old. So each of the vids I caught I was able to patch together the information that interests me.

Good for you, Vicus!

Good choice. If I were to pick one, block blue light would be top of the list especially if you spend a lot of time on blue lit screens. They lower dopamine levels and can set you up for a number of compulsions or addictions.

I’m coming up on a month with the new behaviors. I use to go to bed around 11:00 pm to 12:00 am, now it’s hard to stay up passed 9:00-10:00 pm and I awake before sunrise. Some nights seem long but I still go right back to sleep. There were only two nights that I got up because I couldn’t get back to sleep. I suspect it was because of the supermoon, harvest moon, and a partial lunar eclipse. The second night was during the Northern Lights activity which was a little over a week ago.

One physical thing I notice is often I’ll automatically take a double or triple breath like the kind after a good cry. I notice how relaxed I am right after. And besides the improved sleep, there’s the lingering effects of watching the morning sun. The feeling is carried for hours. Another is brainstorming ideas/solutions around my place come easier. And I was serious about feeling bit more intuitive. I’ve noticed synchronicities that are only meaningful for me, but each time it’s a confirmation that the engine is more finely tuned.

I’ll add the first part of my post here because a good part of it is a repeat. But it explains how I've changed up other things as well.

My focus is on: diet, exercise, and sleep. I’m good with the first two. Sleep health was a distant 3rd. I shouldn’t be surprised that Dr. Jack’s information was synchronistic.

I use DayMax Glasses when I’m on the computer. They eliminating 100% of the harmful blue light. And switch to Nightfall Blue Blocking Glasses at sun down. I also have changed the incandescent bulbs for amber incandescent bulbs because they don’t have the blue-green spectrum that can effect the natural sleep patterns.

I have a motion sensor red light in the bathroom. It doesn't interfere with the natural sleep patterns when I get up, so I’m able to go right back to sleep. It’s 100% blue and green light free, has zero flicker, and is low EMF.

For the morning routine, I spend first 15-30 minutes soaking in the rising sun. Dr. Jack explain that sunrise and sunset are potent times. You only need 1-3 minutes and also get as much sun as possible during the day.

Sweet dreams, Vicus.

[Harmony]

Thank you Paula for drawing our attention to this marvellous information from Dr. Jack Kruze, and your personal experiences too. I am already making changes to my day to optimise getting more balanced light frequencies and I will work towards some computer screen protection in the near future.


Hopefully other members can report back about their experiences too .

Night owl

There is nothing on this planet that could steal my sleep! (maximal 7 hours...)

And all my life been a Sun worshiper...inclusive now with fall temperature I ride my bike 2/3 times in the week to my favorite lake and bade in the Sun...or I go to a place 300m from home with open view to a big water canal with banks were I take my Sun doses every day... (never use sun blocker, maybe sometimes in Sumner "after sun" stuff...)

All my life been a active night owl,sometimes too much computer... that's what the glasses are for...

In time I will post my experiences with that...

You’re welcome, Harmony. I'm happy to hear it's helped you make beneficial changes. The info encompasses a number of aspects. And it only requires a few tweaks to enhance our quality of life in a world that’s got a heck of a lot going on designed to do the opposite.

A special shout out to "a very kind, longstanding Avalon follower" for contacting Bill. And thank you, All, and to Bill for the space to share.

Before I wind down on the thread, I wanted to add an image that shows the spectrum distribution from light sources.

The diagram shows the spectral test report of the three different types of lighting, compared with sunlight.

• The LED lamp is shown by the blue line 
• CFL (compact fluorescent light) light is green
• The incandescent bulb is purple
• The solar spectrum (sunlight from the sun) is shown in yellow

Are LED Lights Bad For Your Eyes?

As you can see, light is composed of different types of colours. Sunlight is made of all the colours of the rainbow. Out of the seven colours, it’s only blue light (and a small amount of green light) that has health concerns. As you can see from the graph, the LED light show a huge spike of light in the blue light area, in the range of 300-455nm.

This is more than the other types of lighting- CFLs and incandescent bulbs. 

When our retinas are exposed to chronic blue light, a host of problems can occur, including visual fatigue, eye diseases, sleep disturbances etc. This is because we have special receptor cells on our retina called ipRGCs (intrinsically photosensitive retinal ganglion cells) which are responsible for detecting blue light only. No such cells exist for the other colours of the light spectrum. The job of these photoreceptor cells is to tell the brain whether it’s nighttime or daytime, according to the blue light received from the sun. When it receives untimely input (such as when you LEDs on after dark), it messes with your body’s natural functioning and disrupts your circadian rhythm. 

Secondly, blue light is very high in energy. In the graph above, as you move towards the warmer colours (yellow, orange and red) the wavelengths decrease and therefore the intensity of the light decreases. As you move to the cooler colours, the wavelength and energy intensity increase. When our eyes have to focus on these high-energy pixels for long periods, it can cause visual fatigue.

Lastly, LED lights have ‘invisible flicker’ due to the AC Mains power. Flicker is a fluctuation in the intensity of light and it’s of two types;

• Visible flicker (under 100 Hz)
• Invisible flicker (more than 100 Hz)

We can’t see the invisible flicker in LEDs with our naked eyes. However, if you put your smartphone in slow motion video and record an LED source, you can see for yourself the visible distortion in light. Studies have revealed that long-term exposure to flicker can lead to eye strain, headaches, blurred vision, fatigue, reduced visual task performance and even neurological problems in some scenarios.
