Good morning. It's September 27.

Andy Mant used to dread his alarm every single morning. The thought was always the same: one more hour. Then he discovered that the light he was exposing himself to every evening was biologically suppressing his melatonin and keeping him in a state of chronic sleep deprivation.

What he and his partner Katie did with that discovery? Build a wellness brand now shipping to 137 countries: Bon Charge.

Let's dive in and learn all about blue light, red light, and recovery 🙌

The rundown:

Let's get to it. 👇

Combining 30 minutes of incline treadmill exercise with 15 minutes of red light therapy produced 32% more fat loss over six weeks than exercise alone - the two groups followed identical protocols; the only difference was sitting in front of a red light panel instead of resting afterward. The mechanism: red light accelerates the clearance of fatty acids mobilised by exercise before they can be reabsorbed. The gap wasn't marginal. It was nearly a third more fat loss. Sene-Fiorese et al., Lasers in Surgery and Medicine

Blue light suppresses melatonin for roughly twice as long as green light - and shifts circadian rhythms by twice as much - Harvard researchers measured the difference and found blue-spectrum light (the kind screens and LEDs emit) causes significantly more circadian disruption than warmer-spectrum light. It's not just about total light exposure at night. The wavelength composition of that light matters enormously. Harvard Health

Regular sauna use is associated with dramatically lower cardiovascular mortality - in a 20-year longitudinal study of over 2,000 Finnish men, those using sauna 4-7 times per week had 40% lower cardiovascular mortality than once-weekly users. The benefits scaled with frequency across two decades of follow-up. Recovery, blood pressure, and heart rate variability all improved - consistently. Laukkanen et al., JAMA Internal Medicine

Nasal breathing during sleep supports deeper, more restorative sleep stages than mouth breathing - nasal breathing activates nitric oxide production, warms and humidifies inhaled air, and supports slower, more regular respiratory rates during sleep. Andy Mant uses mouth tape every night. His wife was skeptical. She isn't anymore. Sleep Medicine

Near-infrared light at 850nm stimulates cytochrome c oxidase - the key mitochondrial enzyme - increasing ATP output in treated tissues - this is the foundational mechanism behind red light therapy. Photons of specific wavelengths displace nitric oxide that was suppressing mitochondrial activity, restoring electron transport and boosting cellular energy production. Not hypothetical. Textbook mitochondrial biochemistry. Hamblin, Photobiomodulation Reviews

In 2016, Andy Mant was running on empty.

Every morning, the alarm would go off and he'd lie there willing himself an extra hour. He'd eventually drag himself out of bed all groggy, grind through the day, and repeat. He assumed it was stress. Or diet. Or just the general texture of modern life.

It wasn't any of those things.

The science Andy stumbled into

At night, the human body is supposed to produce melatonin - the hormone that signals darkness has arrived and sleep should follow. But blue-wavelength light (the kind emitted by LED screens, overhead lights, and smartphones) suppresses that production. Your brain encounters a glowing screen and concludes: it's still midday. No sleep yet.

For Andy, this was the missing variable. He started experimenting with blue light blocking glasses in the evenings. He changed his light environment. And his sleep changed with it.

"The alarm would go off, I'd be like: another hour, another hour," Andy has said on The Model Health Show. "And that doesn't happen anymore. I crave jumping out of bed - literally springing out of bed - going outside and just being outside for a few minutes."

The 3-2-1 Method

In parallel, Andy implemented the 3-2-1 method - a structured protocol for the hours before bed that works with biology rather than against it.

3 hours before bed: stop eating. The gut-brain connection matters here. When the digestive system is processing food, it can interfere with melatonin production.

2 hours before: no fluids. Basic sleep hygiene - avoid waking at 2am. Glycine and chamomile together work well as an evening wind-down option before this window.

1 hour before: power everything down. "No devices, no artificial blue light, no TV, no work, nothing. It's parasympathetic time. It's breathwork, it's red light therapy, it's yoga, it's stretching, it's reading. My phone's on airplane mode when I sleep. 100% blackout. Mouth tape as well." says Andy.

The result: a morning where getting out of bed feels genuinely good. Not something you dread.

Andy's wife Katie was initially skeptical of the mouth tape - until she tried it herself. She became a convert. And as Andy started importing blue light blocking glasses in Australia, their circle noticed too.

Building Bon Charge

That demand became Bon Charge. In 2017, they launched with a single product: Blue Light Blocking Glasses. The pitch was simple but loaded with context most people didn't yet have: the light you surround yourself with after dark is actively working against your sleep.

The product sold. Then it kept selling.

But Andy kept asking: what else does light do to the body? Red light, near-infrared, infrared sauna, PEMF - each answer became a product category.

Today: 400,000+ customers across 137 countries. Andy named APAC CEO of the Year, one of Australia's Top 50 Leaders. Katie - Co-founder and Chief Visionary Officer - recognized by Forbes and named in the same Top 50. Both have earned 40under40 accolades.

The brand's Wellness Tech Report 2026, which surveyed 7,000 adults across four countries, found that skin and beauty has now become the primary reason people buy red light therapy devices. A mainstream consumer has arrived who doesn't call themselves a biohacker but is using the same tools Andy discovered to fix his own biology a decade ago.

That's what happens when a personal health problem gets turned into a product. Eventually it reaches people who don't know they have the same problem yet.

The 32% extra fat loss with infra-red recovery after treadmill exercise from the Turn Back section sounds dramatic. Here's why infra-red recovery after exercise is real - and why the mechanism matters beyond fat loss.

When you exercise - particularly aerobic exercise - your fat cells release stored lipid content into your bloodstream. The goal is to burn that fat as fuel. But not all of it gets burned during the workout. Some gets mobilised, doesn't reach active combustion, and gets reabsorbed by fat cells afterward.

Red light therapy disrupts that reabsorption process.

Research shows that red and near-infrared light (specifically 630-660nm and 850nm wavelengths) causes temporary pores to form in fat cell membranes - a process called transient cytosol vacuolisation. These pores allow stored lipid content to leak out and enter the lymphatic system, where it gets cleared from the body rather than returned to the fat cell.

The timing is critical. When exercise and red light are stacked - specifically, red light applied directly after exercise while fatty acids are still mobilised - the clearance effect compounds the exercise effect. The fat that exercise sent into the bloodstream gets cleared rather than reabsorbed. That's the 32% difference.

The same biology across different applications:

Different tissues. The same fundamental biology: red light stimulates mitochondria, and mitochondria do their job better.

The science behind Bon Charge's Red Light Face Mask is the same mechanism FROM THE CLINIC broke down: specific wavelengths of light (660nm red and 850nm near-infrared) penetrate the skin and stimulate mitochondrial activity in the cells that produce collagen, reduce inflammation, and repair tissue.

In practice: 10-20 minutes per session, hands-free wearable design, targeting collagen production, fine lines and wrinkles, skin tone and texture, and surface inflammation. Clinical red light has been studied in dermatology for decades. The mask format makes daily use at home realistic without clinical visits.

For years, the concepts behind blue light and melatonin, circadian rhythms, light as medicine - lived primarily in academic research and biohacking forums. That's changing.

Chronobiology, the science of how biological processes synchronise to time, is now influencing clinical guidelines in sleep medicine, metabolic health, and oncology. Some cancer treatments work significantly better at specific times of day - a field called chronopharmacology that's generating serious research attention.

More practically: the American Medical Association has issued guidance on LED street lighting and blue light hazard. Schools are trialing circadian-friendly lighting systems. Hospitals have redesigned ICUs to incorporate natural light cycles. The light environment - which was a biohacking concept five years ago - is now a clinical design parameter.

The underlying science is the same science that made Andy Mant's blue light blocking glasses sell.

This is what biohacking going mainstream actually looks like. The interventions that wellness-forward consumers adopted first - managing light environments, blocking disruptive wavelengths, building recovery rituals around circadian biology - are now entering institutional medicine. The consumer market, as often happens, was running five to ten years ahead of clinical consensus.

The oral microbiome is increasingly recognised as central to systemic health. Gum disease is linked to cardiovascular disease, metabolic dysfunction, and cognitive decline. The oral cavity is not separate from the rest of the body.

Bon Charge's Red Light Toothbrush applies photobiomodulation to oral health: specific wavelengths target gum tissue to reduce inflammation and support cellular repair - the same biology applied at a different site. No chemicals, no abrasives. Two minutes, same mechanism, different tissue.

If you take the oral-systemic health connection seriously - and the research increasingly says you should - this is a practical addition to the daily stack.

Bon Charge published its Global Wellness Tech Trend Report 2026 this year - surveying 7,000 adults across the US, UK, UAE, and Australia. The most striking finding: skin and beauty has emerged as the primary motivation for red light therapy adoption worldwide.

Not sleep. Not recovery. Not longevity. Skin.

This is a meaningful data point about where the consumer wellness market actually is. The biohacking audience that drove early adoption was motivated by performance and longevity. The new consumer arriving at the category is motivated by their face. The market is validating that shift.

The numbers behind it: the global biohacking market is growing at roughly 25% annually and is projected to exceed $56 billion by 2030. Consumer wellness devices - at-home red light panels, wearable masks, personal infrared saunas - are the fastest-growing segment of that market. Clinical-grade photobiomodulation technology that cost $50,000+ in a dermatology practice ten years ago is now available in a portable LED mask for under $200.

The report also found that men and adults under 35 are leading adoption globally, and the UAE is the most engaged market of the four countries surveyed. The longevity consumer is younger, more gender-balanced, and more globally distributed than the biohacker archetype ever suggested.

Bon Charge's own trajectory mirrors this exactly. It began as a sleep and circadian wellness brand. It's become a beauty and longevity platform - not by changing what the products do, but by the mainstream catching up to what the founders already knew.

This week's Founder Story is about a man who fixed his sleep and changed his life. This is the book that explains why sleep deserves that level of attention.

Walker covers what happens when the brain and body sleep - memory consolidation, cellular repair, immune function, emotional regulation, metabolic health - and what the consistent research record says about what happens when we don't. Short, punchy, and unambiguous: sleep is not optional for a long, healthy life. Andy Mant built a company around that insight. Walker wrote the manual.
