Looking decades younger than your chronological age isn’t about expensive treatments or complicated protocols.
According to wellness expert Liz Earle, who appears biologically over 20 years younger than her actual age in her 60s, the secret lies in understanding simple principles that most people completely overlook.
In a recent conversation, Earle revealed the fundamental shifts that transformed her aging process—and they’re surprisingly accessible to everyone.
The biggest game-changer? Understanding circadian rhythm and our relationship with daylight.

Sky Before Screen: The Morning Light Revolution
Earle’s number one rule is deceptively simple: don’t look at your phone until you’ve looked outside and seen daylight.
Within the first 10-15 minutes of waking, exposure to natural light triggers a cascade of biological processes that set up your entire day—and potentially your entire aging trajectory.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
It’s sky before screen. Don’t look at your phone until you’ve looked outside and seen some daylight.
Those early morning light signals entering the retinal cells in your eyes trigger inflammatory chemicals, the hormone cascade, cortisol production, and later chemicals like dopamine. They also set up melatonin production for later in the day, ensuring better sleep at night.
If getting outside isn’t possible, simply opening a window works. Earle brushes her teeth in front of an open window every morning, regardless of weather or season.
Light Isn’t Just Light: Understanding the Spectrum
Most people think sunlight equals UV rays—UVA for aging, UVB for burning. But light is far more complex, containing numerous wavelengths that serve different biological functions.
Early morning light, before sunrise, contains near infrared and far infrared wavelengths—with no UV at all. This means no need for sunscreen during these crucial hours.
Professor Richard Weller, chair of clinical dermatology at Edinburgh University, has made a bold statement about our current relationship with sun exposure.
We will look back at this time and our lack of sun exposure as being as damaging to our health as smoking.
Weller’s research discovered that UVA triggers nitric oxide production through the skin—a powerful compound that helps prevent cardiovascular disease and improves arterial flexibility.

Preparing Your Skin: The Adaptation Protocol
Early morning light exposure does something remarkable: it prepares your skin for stronger sunlight later in the day.
Those morning light signals communicate with fibroblasts in the skin—cells responsible for producing collagen and elastin. The skin begins making anti-inflammatory protective chemicals, produces nitric oxide, and increases collagen and elastin production.
Without that early signaling, skin isn’t prepared for stronger wavelengths later. This lack of preparation is what causes pigmentation issues, as melanin forms into clumps and clusters when skin hasn’t adapted properly.
Starting now, in late spring, allows gradual adaptation by getting 5-10 minutes of early morning exposure when UV is low. The skin thickens slightly, becomes stronger, and produces more collagen—exactly what retinols aim to achieve, but naturally.
Indoor Lighting: The Junk Food Equivalent
If outdoor light is nutritious food for your mitochondria, indoor LED lighting is the junk food equivalent.
LED lights emit short-wave blue light exclusively. Mitochondria—the energy-producing organelles in cells—thrive on broad-spectrum light. When deprived of it, they go into significant decline.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Professor Glenn Jeffrey, a neuroscience and ophthalmology professor at UCL and Moorfields, discovered a remarkably simple solution: add one or two old-fashioned incandescent light bulbs to your home.
These bulbs provide the broad-spectrum light mitochondria crave, balancing the blue light from screens and overhead lighting. A desk lamp with an incandescent bulb costs around £1.50 and can fundamentally change how your cells function throughout the day.
Water: From Dead to Living
Ancestrally, humans consumed water bubbling up from underground aquifers, running through streams, purified by rocks, and rich in trace minerals. Earle describes this as “living water.”
Modern tap water, by contrast, resembles ultra-processed food. It’s been through human bodies multiple times, chlorinated, often fluoridated, stripped of minerals, and likely contains traces of pesticides, pharmaceutical residues, and hormones.
Earle’s water protocol involves three steps:
- Filter it: Use a simple water filter, preferably glass to avoid microplastics
- Remineralize it: Add electrolytes (potassium, magnesium, sodium) or simply a pinch of Celtic sea salt
- Structure it: Expose filtered water to sunlight for 30 minutes, which creates “structured” or EZ (exclusion zone) water
The electrical charge from minerals is crucial because cells run on electric current. Adding minerals to morning water creates a noticeable brain-waking effect that caffeine alone cannot achieve.

When you put minerals in your water, feel like it really wakes up your brain. Yeah, definitely. You can feel that sort of electrical charge. We are electrical beings.
Structured Water: The Fourth Phase
Professor Gerald Pollack at Washington University discovered a fourth phase of water: structured or EZ (exclusion zone) water.
Cells run on structured water, and mitochondria create it—but only with adequate sunlight exposure. Under magnification, structured water appears ordered and aligned, while unstructured water looks jagged and rough.
Methods to structure water include:
- Exposing it to sunlight
- Vortexing (swirling) it
- Consuming foods with gel-like textures (chia seeds in water)
While the science is emerging, companies measuring ATP (cellular energy) production before and after structured water consumption have shown promising results.
Grounding: Reconnecting with Earth’s Energy
Humans evolved walking barefoot, constantly connected to Earth’s natural resonance called the Schumann resonance. Modern life—indoor living, synthetic shoe soles—has severed this connection.
Direct contact with soil, grass, concrete, stone, sand, or water restores this energetic connection. Small studies show grounding lowers cortisol levels and reduces inflammation.

When getting morning daylight, remove shoes and socks. The combined effect of light exposure and grounding amplifies benefits.
The Non-Negotiable Foundations
Earle emphasizes that certain pillars remain fundamental for midlife women:
- Increased protein intake as we age
- Resistance training and weight lifting
- Prioritized sleep
- Optimized hormone health
However, understanding circadian rhythm and the relationship with daylight “moved the dial” more than anything else for her biological age reversal.
Practical Implementation: Start Today
Earle follows the 80/20 rule—80% consistent with routines, 20% living life with balance. Perfection isn’t the goal; consistent small actions create transformation.
Immediate actions to implement:
- Get an old-fashioned alarm clock; stop using your phone
- Within 10-15 minutes of waking, look outside or open a window
- Brush teeth in front of an open window
- Add one or two incandescent bulbs to frequently used spaces
- Put a pinch of Celtic sea salt in morning water
- When driving, crack the window open slightly (light bounces around, reaching you)
- Take outdoor breaks during the workday, especially near sunset
- Remove shoes and stand on earth, grass, or sand when possible
The Sunscreen Controversy
Earle addresses the contentious sunscreen debate with nuance. If applied properly—thickly and completely covering skin—sunscreen blocks vitamin D synthesis. Most people don’t apply it properly, which is why some still produce vitamin D while wearing it.

Her concern extends beyond vitamin D. Synthetic sunscreens may disrupt the skin’s microbiome, which communicates directly with the immune system. Dermatologists are seeing increased inflammatory skin conditions potentially linked to unnecessary sunscreen overuse.
Drink a bit more water, maybe with a pinch of salt. It really is that simple and is fundamentally going to change how you age.
For fair-skinned individuals in strong midday sun, she recommends covering skin with clothing and hats rather than chemical sunscreens. The key is judicious use—wearing SPF 50 on the London Underground in winter, as one public health campaign suggested, makes no biological sense.
Looking 20 years younger isn’t about expensive interventions. It’s about realigning with the fundamental inputs humans evolved with: natural light exposure, mineralized water, and connection with Earth’s energy. These free, accessible tools may prove more powerful than any supplement or treatment available.
