Amber light, fat cells, and nature Researchers took human fat cells and shined different colors of light on them.. violet, blue, green, yellow, amber (nanometers), and red Only one wavelength consistently did something dramatic: Amber light made fat cells break down their stored fat droplets. This wasn’t done by the normal fat burning hormone pathway, but by turning on the cells cleanup and recycling machinery Autophagy + lysosomes = internal fat digestion. Autophagy being the cell’s self-cleaning process, and lysosomes being acidic sacs that digest waste The cell essentially ate its own fat droplets from the inside out as a result of amber light exposure This pathway is not the classic adrenaline to HSL to fat breakdown route The researchers even blocked the usual lipase pathways, and the amber light effect still happened So, the study tells us that amber light activates the cell’s recycling machinery that destroys fat droplets It’s not a stretch at all to suggest that light wavelengths can influence adipocyte (fat cell) behavior in a measurable way ••• Every wavelength does something different in the body because different molecules and tissues absorb different photons Blue light is highly stimulating and alerting. Red and infrared boosts mitochondrial ATP. UV-A and UV-B offer distinct benefits Amber sits in an interesting middle zone because it penetrates deeper than blue, carries more energy than red, and interacts with metabolic tissue like fat Amber is also heavily involved in: • cerebellar development • circadian signaling • mitochondrial dynamics • melanin intermediates • POMC related pathways Fat cells responding to amber light fits the pattern of amber being a metabolic wavelength Amber exists in the natural world for your benefit. It’s most abundant during sunrise and sunset due to Rayleigh Scattering, where you have a high concentration of red/infrared/oranges/yellow/ambers Golden hour is an amber rich experience You literally bathe in amber light just by stepping outside during sunrise and sunset Firelight offers a lot of amber along with many of the same wavelengths that sunrise and sunset provide Full spectrum sunlight during the day offers amber as well, but at less concentration since it’s mixed with the rest of the spectrum Incandescents are a man-made lighting source that is rich in amber light By maintaining circadian alignment, you bring amber back into your life during both the day (sunrise, sunbathing, sunset, incandescents) and night (firelight & low lux incandescents)

The undeniable evidence that your mitochondria are light-sensing organelles which use the sun’s full spectrum for energy production Here’s what will put those who speak ill of the sun to shame Let’s start with the basics Your body evolved to be under the sun’s full light spectrum, which is why every aspect of it is designed to sense and use light How can I prove this? Because we have chromophores all over the exterior and interior of our bodies Chromophores are molecules or parts of molecules responsible for the color of compounds They are typically the parts of a molecule that absorb visible light or ultraviolet light, leading to electronic transitions When a chromophore absorbs light, it moves to an excited state, and the energy associated with this transition often falls within the visible spectrum, which is why we perceive color So, how does this tie into the mitochondria? Well, each mitochondrion in your body contains a series of complexes which are designed to transfer electrons through redox reactions to produce energy (ATP) This chain of complexes is what we call the electron transport chain, and it’s found within the inner mitochondrial membrane Mitochondria are the lifeblood of each cell, hence they make all the difference between health and disease, life and death It ties in perfectly because of this fact: The entire electron transport chain is LOADED with chromophores which are critical to the function of these complexes Now here’s where it gets fun I told you that your mitochondria are light-sensing organelles Now here’s why ⚡️ Complex I (NADH:Ubiquinone Oxidoreductase) • Flavin Mononucleotide (FMN): Absorbs light at around 370 nm (UV) and 450 nm (blue light) • Iron-Sulfur Clusters: These clusters have broad absorption, typically in the 400-600 nm range, but they don’t have distinct peaks like other chromophores ⚡️ Complex II (Succinate:Ubiquinone Oxidoreductase) • Flavin Adenine Dinucleotide (FAD): Absorbs at around 370 nm (UV) and 450 nm (blue light) • Iron-Sulfur Clusters: Similar to Complex I, absorption is broad and typically in the 400-600 nm range ⚡️ Complex III (Cytochrome bc1 Complex) • Cytochrome b: - bL (low potential form): Absorbs at around 563 nm (yellow-green) - bH (high potential form): Absorbs at around 566 nm (yellow-green) • Cytochrome c1: Absorbs at around 552 nm • Rieske Iron-Sulfur Protein (2Fe-2S cluster): Absorption is broad, typically between 400-500 nm ⚡️ Complex IV (Cytochrome c Oxidase) • Cytochrome a: Absorbs at ~ 605 nm • Cytochrome a3: Absorbs at ~ 655 nm Both orange and red light absorbed here • Copper Centers (CuA and CuB): These centers absorb broadly in the visible region, but their exact absorption properties are less defined than the heme chromophores ⚡️ Additional Chromophores in the ETC Ubiquinone (Coenzyme Q): Ubiquinone itself is not strongly absorbing in the visible spectrum but does have weak absorption peaks in the UV range, around 275-290 nm Biophoton emission right there ⚡️ Cytochrome c (Mobile Carrier) Cytochrome c has an absorption wavelength of ~ 550 nm (in reduced form) Now here’s the million dollar question Why does the entire electron transport chain sense various wavelengths of light from the sun at extreme precision? I want to see the look on every physician, dermatologist, and ophthalmologist’s face when they’re shown this information The overall absorption range of the chromophores within the electron transport chain is between ~ 200 nm to ~ 900 nm From extremely low-frequency UV light (biophotons) to NIR light Any argument against sunlight exposure or the use of sunglasses, sunscreen, sun-avoidance is hereby deemed as retarded knowing this information This is especially the case because mitochondria control the health of every cell and are found everywhere in the body I rest my case image

If you’re not dedicating time to proper sunbathing with a large portion of your skin exposed, you’re not giving yourself the chance to produce meaningful amounts of vitamin D3 from UV-B exposure For some reason, many people assume that simply going to a baseball game without sunglasses or a hat, while keeping most of their skin covered with clothes, will somehow generate sufficient vitamin D3 Absolutely not You need actual skin in the game at the correct times and in circadian alignment Sunlight must strike bare skin directly, and ideally in a consistent, intentional way. It’s not something you stumble into by accident. It requires a dedicated practice Watching sunrise? Great, you’re still not making D3 Making it dark at night? Great, still not making D3 UV-A rise? Fantastic, still not making D3 You must be sunbathing with BARE SKIN when UV-B is present to begin the conversion process in your body Let me remind you of the conversion process involved here: 1. UV-B hits the skin and penetrates into the epidermis (outer most layer of the skin) 2. UV-B changes the shape of the starting molecule known as 7-DHC (7-dehydrocholesterol) 3. This UV-B induced change turns 7-DHC into Pre-Vitamin D3. With heat, pre-vitamin D3 naturally rearranges into Vitamin D3 (cholecalciferol) 4. That’s where binding for transport occurs. Vitamin D3 cannot float freely in the blood, so it binds to a carrier called DBP (Vitamin D Binding Protein), forming DBP-VD3 5. Once bound, it moves through the bloodstream where it can later be activated in the liver and kidneys into the full active hormone form (calcitriol) I have bad news if you use any form of SPF as well, so prepare yourself SPF 15 blocks ~93% of UV-B SPF 30 blocks ~97% of UV-B SPF 50 blocks ~98 of UV-B SPF 100 blocks ~99% of UV-B So if you use any form of sunscreen, whether chemical or mineral based, you’re blocking the very light wavelength range needed to produce D3 (also one of your most potent anti-cancer hormones) Negligible conversion is happening, even if you do a shitty job of applying your sunscreen considering the chronic circadian disruption that a modern lifestyle creates, further worsening D3 status People who don’t have a strong circadian education are likely to make these simple mistakes And I see it time and time again image
