TL;DR
Red light therapy works by giving your cells energy to heal themselves.
Brain health isn’t just about the brain, your gut plays a major role.
Recovery is often the missing link in improving health and performance.
Modern life (low sunlight, high stress) is increasing inflammation.
Simple habits, light, sleep, and consistency, can make a real difference.

Introduction
What if the problem you’re trying to fix… isn’t actually where the problem starts?
That’s what stood out most to me in this conversation.
I sat down with John Graham Harper, founder of Lumaflex, to unpack red light therapy, something I’ve seen everywhere in the health space but never properly understood. Like a lot of people, I’d always had it in the back of my mind… but also questioned whether it was just another trend.
What I didn’t expect was how quickly the conversation expanded beyond just a “tool” and into something much bigger, how the body actually heals.
John’s journey started with injury. Years of training across rugby, boxing, and CrossFit left him dealing with chronic pain, particularly in his knee. After trying everything, from braces to creams, he discovered red light therapy through a simple lamp. Within weeks, things changed.
But what’s more interesting isn’t just the tool, it’s the idea behind it.
This episode is really about understanding recovery, how the body works at a deeper level, and why so many of us are missing the basics.

Lesson 1: Red Light Therapy Works at a Cellular Level
What It Is:
Red and near-infrared light therapy uses specific wavelengths of light to stimulate your cells, particularly your mitochondria (the part of the cell that produces energy).
Why It Matters:
Most treatments focus on symptoms, pain, inflammation, fatigue. But this approach works deeper. It supports the body’s ability to heal itself by increasing cellular energy.
As John put it:
“It’s not really the light that does the healing, it’s the light that gives energy to your cells to heal themselves.” - John Graham Harper
How To Apply It:
Focus on consistency over intensity, short, regular sessions are key.
Apply light directly to the area you want to target (e.g. knee, back, neck).
Use it daily, ideally morning and evening.
Think of it as supporting recovery, not replacing other habits.
Pro Tip: Don’t overcomplicate it, consistency beats perfection.
Try This Today: Spend 10 minutes focusing on recovery, whether it’s light therapy, stretching, or simply slowing down.
Lesson 2: Brain Health Starts in the Gut
What It Is:
Your gut and brain are deeply connected, often referred to as the “gut–brain axis.” Issues in the gut can directly affect mood, clarity, and overall brain function.
Why It Matters:
We often try to fix brain-related issues (like brain fog, low energy, or mood) by focusing only on the head. But the root cause may be somewhere else entirely.
“A lot of the problems with your brain are in your gut.” - John Graham Harper
How To Apply It:
Start paying attention to digestion and gut health.
Prioritise whole, unprocessed foods where possible.
Notice how different foods affect your energy and mood.
Support your gut through sleep, hydration, and stress management.
Pro Tip: If you’re feeling off mentally, don’t just look at your mindset, look at your lifestyle.
Try This Today: Eat one meal slowly and mindfully, notice how your body responds.
Lesson 3: Recovery Is the Missing Link
What It Is:
Recovery is the process where your body repairs, adapts, and improves. It’s not just rest, it’s where progress actually happens.
Why It Matters:
Most people focus on training, work, or output, but neglect recovery. This leads to burnout, injury, and stagnation.
John highlights this clearly:
“Recovery is often the missing link in performance and longevity.” - John Graham Harper
How To Apply It:
Prioritise sleep, this is your foundation.
Use simple tools: walking, stretching, breathwork.
Add recovery methods like heat (sauna) or cold exposure.
Build recovery into your routine, not just when you’re injured.
Pro Tip: If you’re always tired, the answer isn’t more effort, it’s better recovery.
Try This Today: Go to bed 30 minutes earlier than usual.
Lesson 4: Modern Life Is Increasing Inflammation
What It Is:
Inflammation is your body’s response to stress. While some is normal, chronic inflammation (ongoing, low-level stress in the body) can lead to long-term health issues.
Why It Matters:
Our environment has changed dramatically, less sunlight, more screen time, more stress. All of this contributes to higher inflammation levels.
“We’re 85 to 90% deficient in sunlight. It’s creating problems.” - John Graham Harper
How To Apply It:
Get natural sunlight daily (even in winter).
Reduce screen exposure, especially at night.
Create clear boundaries between work and rest.
Spend time outdoors whenever possible.
Pro Tip: You don’t need extreme changes, small daily habits add up.
Try This Today: Step outside for 5-10 minutes of sunlight.
Lesson 5: Consistency Beats Everything
What It Is:
Consistency means doing simple things regularly over time, not chasing quick fixes.
Why It Matters:
Whether it’s light therapy, training, or nutrition, the biggest results come from what you do repeatedly.
John emphasised this throughout the episode:
“Consistency of use… is what brings about recovery and change.” - John Graham Harper
How To Apply It:
Choose 1-2 habits you can realistically stick to.
Keep them simple and repeatable.
Track your progress weekly (not daily).
Focus on long-term improvement, not short-term results.
Pro Tip: If it’s too hard to maintain, it won’t last.
Try This Today: Pick one habit and commit to it for the next 7 days.
Mini Case/Example
John shared how he used red light therapy to recover from chronic knee pain after years of issues:
“After a week I didn’t have this pain… and then after another week, I didn’t need it anymore.” - John Graham Harper
This wasn’t about a quick fix, it was about consistent use and supporting the body’s natural healing process.
Quick Wins Checklist (Do These Today)
Get at least 5-10 minutes of natural sunlight
Go to bed slightly earlier than usual
Focus on one recovery habit (stretching, walking, breathwork)
Eat one whole-food meal and notice how you feel
Reduce screen time before bed
Closing Insight
This episode isn’t really about red light therapy.
It’s about stepping back and asking a better question: how does the body actually heal?
When you start to look at health this way, things begin to connect. Brain, gut, recovery, sleep, environment, it’s all part of the same system.
Tools like red light therapy can help, but they’re not the foundation. The foundation is simple: consistency, awareness, and getting back to the basics.
If you can start there, everything else becomes easier.
