Here’s the circadian truth about the infamous truck driver case - the one centralized dermatologists love to weaponize against sunlight exposure: This is the most misunderstood image in the health space when it comes to photoaging and skin cancer

It’s a case study that’s been twisted out of ignorance to fuel misinformation about sunlight

Circadian biology is the master regulator of all anti-cancer processes in the body

Through this, we understand that the demonization of sunlight, along with the lack of discussion about artificial light at night and circadian disruption, creates rising cancer rates

Here’s all the evidence you need Virtually all major anti-cancer processes are either directly or indirectly controlled by circadian biology

Some processes might seem less dependent on circadian rhythms at first glance

But it inevitably comes full circle

Why full-spectrum sunlight and circadian alignment are the ultimate probiotics and gut healers

I’m using first principles circadian biology and gut physiology to show you the power of this work

Gut health transcends what you eat We begin with the basics

The gastrointestinal system operates as a CIRCADIAN organ, which means it’s married to the light and dark cycle

Circadian biology regulates all aspects of gut physiology from motility to digestion to absorption to electrolyte balance

This is the bedrock of gut health

The Sun Paradox

Exposing the glaring contradictions of centralized dermatology, so you don’t fall fall prey to their iatrogenic interventions Centralized dermatology oversimplifies the sun-cancer connection while ignoring other major factors like isolated blue light, circadian disruption of the skin, the difference between isolated UV versus UV in the full spectrum, Vitamin D deficiency, and more

They push fear-based avoidance, which often leads to worse long-term health outcomes

Does the sun really cause skin cancer?

I’ll tell you why the studies are lying Research linking UV light to skin cancer is flawed due to poor study design, relying on isolated UV in nocturnal animals or cell cultures instead of full-spectrum sunlight on humans

This one idea changes your epistemological foundation regarding this subject

Why cloudy days are still worth stepping out for — and how the sun’s full spectrum is available through cloud cover: “Why should I go outside during winter or when it’s cloudy, there’s no sunlight!”

I’ve received this comment often

Let’s set the record straight on this subject and answer the question, once and for all

Even though you naturally want to stay wrapped up in a blanket during overcast days, the sun's full light spectrum continues to play a vital role in your health, regardless of the weather

Why full spectrum sunlight makes the skin more youthful — and how isolated blue and UV is toxic to the skin barrier: Let’s begin from first principles

If you’re religious or believe in evolutionary biology and adaptation, you can agree to this:

The skin barrier was made or evolved under the influence of full spectrum sunlight

There’s substantial evidence for this

Some things I’ve learned from reading The Nourishing Traditions Book of Baby & Child Care as a father

Here are some gems for you: Nutrition & Physical Degeneration by Weston A. Price is a must read for parents

Price was a dentist and nutrition researcher who studied traditional societies and found that nutrient-dense, whole foods led to excellent health and resistance to disease

His work highlighted the negative effects of processed diets and emphasized the importance of fat-soluble vitamins, raw dairy, organ meats, and fermented foods for optimal health

13 incredible facts about circadian biology 1. Every cell has a clock

Virtually every cell in your body in your body contains its own circadian clock, regulated by clock genes, which synchronize with your central clock in the brain (the SCN)

How getting UV-A shortly after sunrise will transform your mental health, protect you from sunburns, and deepen the quality of your sleep

Share this with a friend in need The circadian types love to speak about the importance of watching sunrise, but we need to go deeper

This thread is all about UV-A

UV-A light generally appears 15–30 minutes after sunrise, depending on your geographic location, altitude, and atmospheric conditions

It becomes noticeable as the sun rises higher and the atmosphere scatters less of the ultraviolet radiation

You sound ignorant when you say a tan is exclusively a sign of skin damage, here’s why

It’s time to understand melanin

Share if you learned something new Let me remind you that melanin has been conserved for hundreds of millions of years

It’s one of the most ancient and widespread biopolymers, found in a diverse range of organisms, including bacteria, fungi, plants, and animals

Here’s my response to anyone who claims that full-spectrum sunlight, particularly UV light in that context, is harmful to the skin

Bookmark and share this thread The following pictures showcase the lost faces of history, highlighting the raw, regenerative power of full-spectrum sunlight on the skin barrier

These pictures were taken in the early 1900s through the work of Dr. Auguste Rollier

But first, some context

Your body requires the sun’s raw, unfiltered full-spectrum light for the prevention of chronic diseases

Here are the benefits of each light wavelength, to a depth you’ve never seen before Ultraviolet (UV) Light

UV-C (100-228 nm):

Biophoton emission responsible for cellular communication and systemic function. DNA/RNA, tryptophan, tyrosine, phenylalanine, all aromatic amino acids, phospholipids in cell membranes, water, all absorb light within this range

Found this German company called LICHTBLOCK that offers these, and I have never been more pissed that a company doesn’t offer international shipping

If you own a photobiomodulation/circadian company, you need to be making these immediately

Send me a DM if you are

I want everything to do with these


Found their IG. About to DM them. Will keep all of you updated

Our evolutionary and circadian history readily shows that the use of modern sunglasses is antithetical to the function and health of our ocular system

But, there are historical examples of indigenous innovation

Here are some: If you’d like to understand my position on sunglasses and why they’re problematic for human health from a circadian standpoint look, study the thread below

Conductive sweat glands?

The human body has them

Here’s yet another piece of strong evidence as to why grounding isn’t pseudoscience:
Yes, human sweat glands are conductive due to the electrolytes (sodium, potassium, chloride) in sweat

But you must understand the difference between eccrine and apocrine sweat glands

20 circadian principles that will improve your quality of life, no matter your age or circumstance 1. Watch sunrise every AM

If you don’t have a clear view of the sun and horizon, don’t worry

Merely being outside at this time is enough because the outdoor environment is bathed in the sun’s full spectrum at all times

What matters more for the prevention of cancer (especially melanoma and non-melanoma skin cancer)..

Circadian biology or food?

Here’s a thread for the people who are convinced that diet is a more powerful intervention

If this resonates, share the thread

I’m proud of it I’ll begin by saying that every pillar of health must be in order to PREVENT cancer

Light environment, nutrition, detoxification, exercise, all of it is a key part of the discussion

You should strive to have a well-rounded lifestyle

1. I’m not saying you can eat like shit and get away with it

2. I am speaking on prevention of cancer, not treatment when you have been diagnosed with a form of cancer

3. There are hundreds of different cancer types that act differently when they manifest. Brother @AbudBakri can correct me on anything I’ve missed or may have gotten wrong

I already know many of you are going to attack this thread based on those points, which is why I’ve addressed them directly

I appreciate Dr. Teo’s perspective starting at this point because he doesn’t throw the baby out with the bath water like other dermatologists

I disagree with his standpoint that you can get enough D3 synthesis by exposing your arms or a single body part only

I’m always a believer in more skin in the game for various reasons like the development of melanin systemically and locally

Dr. Teo didn’t cover anything about melanin production as it relates to people’s skin tolerance here

All mammals can develop more melanin with a wise approach to building a tan

From red heads to darker skinned people via either pheomelanin or eumelanin

I keep saying that circadian biology touches and influences every aspect of health

Here, we have a fantastic example of this with breastfeeding and its circadian aligning benefits on infants

This realm never ceases to amaze me

Another reason why Enzo is an absolute UNIT 🦍
