The Energy Code

In this episode of The Energy Code, Dr. Mike Belkowski explores why circadian rhythm is not merely a sleep issue — it is a foundational regulator of metabolism, hormones, cardiovascular health, inflammation, cognition, mitochondrial function, and longevity. Drawing from five influential research papers, Dr. Mike explains how the eyes act as circadian sensors, why the timing, spectrum, and intensity of light all matter, and how modern life creates a damaging mismatch: too little bright, full-spectrum light during the day and too much blue-rich artificial light at night. He also breaks down why morning sunlight may be one of the most powerful free wellness interventions available — and why nighttime success begins shortly after waking. The episode concludes with practical strategies for designing a more circadian-friendly environment and introduces the BioLight Ember, a portable, rechargeable light with adjustable brightness and three evening-friendly modes: amber, red, and amber/red combined. The central message is simple: you cannot out-supplement or out-biohack a poor circadian rhythm, but you can begin correcting it by sending your biology the right light signals at the right time.

It only knows what signals it receives... Light is the strongest timing signal humans possess. Everything else is secondary.” “If there was one circadian intervention that consistently outperforms nearly every supplement, it’s morning sunlight.” “The goal isn’t to eliminate light altogether (at night). The goal is to become intentional about which light we’re exposing ourselves to and at what time.” “Health isn’t always about adding another piece of technology or nutraceutical. Sometimes it’s simply about changing the environment your biology evolved to expect.” - Key Points ⚡ Circadian rhythm is not simply about sleep; it influences metabolism, hormones, cardiovascular function, inflammation, cognition, mitochondrial health, and longevity. ⚡ Morning sunlight is one of the most powerful free habits for setting the body’s master clock and improving both daytime alertness and nighttime sleep. ⚡ The eyes contain specialized circadian sensors called intrinsically photosensitive retinal ganglion cells, or ipRGCs, that help determine whether the body interprets its environment as day or night. ⚡ The same light can produce opposite effects depending on when it is viewed. ⚡ Morning light advances the circadian clock, increases alertness, supports a healthy cortisol rise, and promotes earlier melatonin onset that evening. ⚡ Bright and blue-rich light at night delays the circadian clock, suppresses melatonin, increases alertness, and reduces sleep quality. ⚡ The body does not know what clock time it is — it responds to environmental signals, with light acting as the strongest timing cue. ⚡ Virtually every major organ and tissue contains its own molecular clock, including the liver, pancreas, gut, immune system, and mitochondria. ⚡ Shift work, late-night eating, artificial lighting, social jet lag, inconsistent schedules, and sleep deprivation all contribute to circadian mismatch. ⚡ Modern indoor lighting is often too dim during the day and too bright at night. ⚡ Typical indoor environments provide roughly 100–500 lux, while outdoor daylight can reach approximately 10,000–100,000 lux. ⚡ Circadian responses depend on both the brightness a

In this Deep Dive, Dr. Mike Belkowski returns to the roots of The Energy Code by examining two newly published reviews on red light therapy. The first explores photobiomodulation for ocular aging and eye diseases, including age-related macular degeneration, dry eye, and childhood myopia. The second evaluates whether PBM can improve sleep quality by influencing brain metabolism, cerebral blood flow, neural networks, and melatonin-related pathways. Dr. Mike breaks down how light interacts with mitochondrial cytochrome c oxidase, improves electron flow and ATP production, and may restore bioenergetics in two of the body’s most energy-demanding tissues: the brain and retina. The episode also examines the LIGHTSITE clinical trials, repeated low-level red-light therapy for myopia, transcranial PBM for sleep, extra-pineal melatonin production, and why proper wavelength, irradiance, and dosage remain essential. The emerging message is that red light may be far more than a tool for skin, pain, and muscle recovery. It may represent an investigational strategy for restoring cellular energy in the tissues responsible for how clearly we see and how deeply we sleep.

Red and near-infrared wavelengths have the capability of improving our systemic melatonin production.” “The gastrointestinal tract is likely the largest source of melatonin in the body.” “If mitochondria contribute to melatonin production, all of a sudden full-body red light therapy becomes imperative for normalizing circadian rhythm.” - Key Points ⚡ Two new reviews examine photobiomodulation for ocular aging and disease and for sleep quality. ⚡ The brain and retina are among the body’s most energy-demanding tissues, making them especially vulnerable to mitochondrial decline. ⚡ Red and near-infrared light interact with cytochrome c oxidase, helping displace inhibitory nitric oxide, restore oxygen utilization, and increase ATP production. ⚡ PBM follows a Goldilocks dose response: too little may do nothing, while excessive light can become inhibitory or pro-oxidative. ⚡ The LIGHTSITE clinical trials reported modest but statistically significant visual-acuity gains of roughly four to five ETDRS letters in patients with dry age-related macular degeneration. ⚡ Ocular PBM may also reduce drusen burden and potentially slow geographic atrophy, although further clinical confirmation is needed. ⚡ Repeated low-level red-light therapy is being studied as a way to slow the abnormal eyeball elongation responsible for childhood myopia. ⚡ Ocular protocols differ by goal: age-related macular degeneration often uses multiple red, amber, and near-infrared wavelengths, while myopia protocols typically use red light alone. ⚡ Wavelength determines penetration depth; device strength primarily determines how quickly a therapeutic dose is delivered. ⚡ High-powered panels should not be used close to the eyes without carefully adjusting distance, exposure time, and irradiance. ⚡ Transcranial PBM may support sleep by influencing adenosine signaling, cerebral metabolism, astrocytes, and prefrontal and thalamocortical networks. ⚡ Current sleep findings are statistically promising, but may not yet re

In this peptide-focused Deep Dive, Dr. Mike explores Humanin, one of the most fascinating and underappreciated mitochondrial-derived peptides in the longevity space. First discovered in 2001 while researchers were searching for molecules that could protect neurons from Alzheimer’s-related toxicity, Humanin appears to act as one of the body’s natural cellular survival signals — helping cells withstand oxidative stress, inflammation, mitochondrial damage, metabolic dysfunction, and age-related decline. This episode breaks down a 2023 systematic review from Biology titled “Humanin and Its Pathophysiological Roles in Aging”, covering Humanin’s unusual mitochondrial origin, its role in neuroprotection, mitohormesis, chaperone-mediated autophagy, metabolic health, cardiovascular function, inflammation, and lifespan research. Dr. Mike also explains why Humanin may deserve a place alongside SS-31 and MOTS-c as one of the top mitochondrial peptides for anyone interested in mitochondrial wellness, resilience, and longevity. (Educational content only, not medical advice.) - Article Discussed in Episode: Humanin and Its Pathophysiological Roles in Aging: A Systematic Review - Key Quotes From Dr. Mike: “Humanin was originally isolated from surviving neurons in the brains of patients with Alzheimer’s disease" "It was named 'Humanin' to reflect its potential role in preserving human health and survival." “Humanin appears to function as one of the body’s natural cellular survival signals... acting as a molecular shield and mitokine." “Humanin restores the communication link that tells the cleanup crew exactly where the toxic debris is hiding.” “By addressing the mitochondrial origin of this inflammation — the leaky battery problem — Humanin hits multiple diseases simultaneously.” "These are the top three peptides if you’re a mitochondriac: SS-31, MOTS-c, and now you can see why the third is Humanin.” - Key Points ⚡ Humanin is a small mitochondrial-derived peptide first discovered in 2001 during research into Alzheimer’s disease-related neuronal protection. ⚡ It was originally isolated from surviving neurons in the brains of Alzheimer’s patients, which helped shape its identity as a cellular survival peptide. ⚡ Humanin is encoded within the mitochondrial genome, specifically inside the 16S ribosomal RNA gene, giving mitochondria their own “voice” beyond ATP production. ⚡ It exists in two forms: a 21-amino-acid version when translated in mitochondria and a 24-amino-acid version when translated in the cytoplasm. ⚡ Humanin is highly conserved across species, suggesting it may play a fundamental role in multicellular survival and stress resistance. ⚡ It may protect against Alzheimer’s-related toxicity by interfering with amyloid beta toxicity and blocking pro-apoptotic pathways like Bax activation. ⚡ Humanin functions as a mitokine, released during periods of mitochondrial stress to coordinate resilience across cells and tissues. ⚡ Humanin levels generally decline with age, although some very old individuals may show compensatory spikes as a last-ditch mitohormetic stress response. ⚡ It supports chaperone-mediated autophagy, helping the cell’s “precision cleanup crew” remove damaged or oxidized proteins. ⚡ Humanin has broad systemic effects, including potential benefits for brain health, cardiovascular aging, insulin sensitivity, visceral fat, lean mass, inflammation, stem cell survival, and reproductive health. ⚡ Animal models suggest even modest increases in circulating Humanin may provide protection against toxic insults and inflammatory markers. ⚡ A synthetic analog called HNG / Humanin S14G may be up to 1,000 times more potent than naturally occurring Humanin in certain models. ⚡ Dr. Mike frames Humanin as the third part of a mitochondrial peptide “big three” alongside SS-31 and MOTS-c. - Episode timeline 0:00–0:40 — Introduction to Humanin as another mitochondrial-derived peptide; article title and source0:40–1:47 — Historical o
