Liz Earle looks at least 20 years younger than her chronological age.
Her biological age backs this up—it’s more than two decades younger than the number on her birth certificate.
In a recent conversation, the wellness expert revealed the surprisingly simple daily habits that transformed how she ages.
These aren’t expensive treatments or complicated protocols—they’re free, evidence-based practices rooted in our ancestral biology.

Sky Before Screen: The Morning Light Revolution
After nearly 40 years writing about wellness, Earle discovered something that changed everything: circadian rhythm and our relationship with daylight.
Don’t look at your phone until you’ve looked outside and seen some daylight.
She calls it “sky before screen,” and it’s become her non-negotiable morning rule.
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
Within the first 10-15 minutes of waking, Earle gets daylight exposure—even if it’s just brushing her teeth in front of an open bathroom window. Those early morning light signals hitting retinal cells trigger hormone cascades, including cortisol production, dopamine synthesis, and melatonin setup for later sleep.
The science is compelling. Professor Richard Weller, chair of clinical dermatology at Edinburgh University, believes we’ll look back at our current lack of sun exposure as damaging to health as smoking.
Not All Light Is Created Equal
Light isn’t one thing—it’s a complex spectrum of wavelengths constantly changing throughout the day.
Before sunrise, near-infrared and far-infrared signals communicate with mitochondria in our eyes, programming cells without any UV exposure present. This is why Earle emphatically states: don’t wear sunscreen first thing in the morning.
The Morning Light Sequence
As dawn progresses, UVA appears first—and contrary to popular belief, it offers benefits. Research shows UVA triggers nitric oxide production through skin, supporting cardiovascular health and arterial flexibility.
Later in the day, UVB arrives—the wavelength that synthesizes vitamin D through skin. In the UK, UVB isn’t even present during winter months, contributing to widespread vitamin D deficiency.

Vitamin D is not actually a real vitamin. It acts more like a hormone.
It’s involved in immune function, metabolism, insulin regulation, bone health, and brain health.
Sunset Signals Matter Too
By sunset, UV wavelengths disappear, leaving mid, near, and far-infrared light. These wavelengths calm the body, reduce stress, and set up melatonin production for quality sleep.
The takeaway? Get light exposure at both ends of your day, even if it’s just opening a window.
Preparing Your Skin for Sun Exposure
Earle and experts in quantum biology advocate for skin adaptation—not avoidance.
The worst approach? Staying indoors all year, then frying yourself on a two-week beach holiday. Skin hasn’t adapted to handle sudden intense exposure.
Early morning light signals communicate with fibroblasts in skin—the cells producing collagen and elastin. Morning light exposure literally primes skin to make more structural proteins.

By going out in early morning light, I’m telling my body to make more collagen.
This preparation helps skin produce protective anti-inflammatory chemicals and prevents pigmentation from forming into clumps and clusters.
The Sunscreen Question
Can you synthesize vitamin D while wearing sunscreen? The short answer: no.
If sunscreen is applied properly (thick layer, complete coverage), it blocks UVB—which means it blocks vitamin D synthesis. Most people don’t apply it properly, so some UVB penetrates, but that also means the sunscreen isn’t working as intended.
Earle isn’t anti-SPF. She advocates for judicious use—applying it when genuinely needed, like during midday sun exposure for fair skin. She personally prefers covering skin with clothing and hats rather than synthetic sunscreens.
Emerging research reveals potential downsides to constant sunscreen use: disruption of skin microbiome, interference with immune cell communication, and increasing rates of inflammatory skin conditions like rosacea and perioral dermatitis.
Indoor Lighting: The Junk Food Equivalent
If outdoor light is nutritious, broad-spectrum nourishment for mitochondria, indoor LED lighting is junk food.
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
Professor Glenn Jeffrey, professor of neuroscience and ophthalmology at UCL and Moorfields, found that short-wave blue LED lighting damages mitochondria and has significant health impacts.
But here’s the good news: you don’t need to redo all your lighting.
The Simple Fix
Add one or two old-fashioned incandescent bulbs to your environment. These broad-spectrum bulbs feed mitochondria the light they crave and balance harsh LED exposure.
- Desk lamp: Use an incandescent bulb while working
- Evening lighting: Switch to lamps instead of bright downlighters
- Bedside: Keep one beside your bed
- Office: Bring a small lamp if you work under LEDs all day
If you can’t change lighting, take regular daylight breaks. Even opening a window helps—light bounces around spaces, it doesn’t just travel in straight lines.
Water: From Living to Ultra-Processed
Ancestrally, humans drank “living water”—bubbling up from underground aquifers, flowing through streams, purified by rocks, and rich in trace minerals.
Tap water is a bit like ultra-processed food.
Modern tap water has passed through human bodies multiple times, been chlorinated, often fluoridated, stripped of minerals, and contains traces of pesticides, pharmaceutical residues, and hormones.

Three Steps to Better Water
First: Filter it. Even a simple glass jug filter improves water quality and taste while reducing microplastics and contaminants.
Second: Remineralize it. Add electrolytes (potassium, magnesium, sodium, calcium) or simply a pinch of sea salt. Earle uses Celtic sea salt, which is pure, unpolluted, and contains high levels of trace minerals.
She adds electrolytes to her first glass of water each morning, replenishing minerals lost overnight through dehydration.
When you put minerals in your water, it really wakes up your brain. You can feel that sort of electrical charge. We are electrical beings.
Third: Consider structured water. Professor Gerald Pollack discovered exclusion zone (EZ) water—the fourth phase of water that our cells run on.
Mitochondria process structured water, and sunlight enables them to do it. You can structure water by placing it in sunlight for 30 minutes or by vortexing (swirling) it.
Hydrogen Water and Shilajit
Hydrogen water (H2 rather than H2O) acts as a selective antioxidant—targeting the most toxic free radicals while leaving beneficial oxidative processes alone.

Earle also uses shilajit—a black rock resin from the Himalayas containing numerous trace minerals. Despite its strong earthy taste, she’s become so accustomed that her body now craves it when she doesn’t add a tiny amount to her morning coffee.
Grounding: Reconnecting with Earth’s Energy
The Earth has a resonance called the Schumann resonance—a slight hum we can’t hear but that our bodies respond to.
Ancestrally, humans walked barefoot and spent time outdoors, maintaining direct connection with Earth’s energetic current. Modern life separates us with synthetic shoe soles and indoor environments.
The practice is simple: Remove shoes and socks when you’re outside getting morning light. Walk on grass, soil, sand, concrete, stone, or rock—all conduct Earth’s energy.
Studies show grounding lowers cortisol levels and reduces inflammation, helping the body become calmer.
Sound Frequencies and Vibrational Healing
Earle incorporates sound baths, gongs, and solfeggio frequencies into her routine—recognizing that our cells respond to vibrational resonance.

Different frequencies tune into different wavelengths in the body:
- Some designed for healing
- Some for energy and mental clarity
- Some for sleep and calm

The 80/20 Approach to Longevity
Earle follows an 80/20 rule with all health practices—80% consistent with routines, eating well, prioritizing sleep, and following circadian rhythms.
20% of the time it’s tequila and cake. Life is for living. You can’t be puritanical about everything.
She emphasizes doing what you can without obsession. Balance matters more than perfection.
The Fundamental Pillars
While Earle covers many advanced concepts in her work, she acknowledges foundational pillars remain non-negotiable for midlife women:
- Protein intake: Increase as you age
- Resistance training: Lift weights regularly
- Sleep quality: Prioritize it consistently
- Hormone health: Address it appropriately
But understanding circadian rhythm and light exposure moved the dial most dramatically for her personal transformation.

Women and Hydration
A critical but often overlooked issue: women especially need to drink more water, and as we age, we lose our thirst signal.
We lose capacity to recognize many bodily signals with age—thirst is one of them. Staying well-hydrated becomes a conscious practice rather than following natural cues.
Simple Changes, Profound Results
What makes Earle’s approach powerful is its accessibility. These aren’t expensive treatments or complicated protocols requiring specialists.
The practices are free and evidence-based:
- See daylight within 15 minutes of waking
- Keep phone away until you’ve seen sky
- Get outside (or open window) at sunset
- Add one or two incandescent bulbs indoors
- Filter and remineralize water
- Add pinch of salt to morning water
- Ground barefoot when getting morning light
- Take regular daylight breaks if working indoors
These habits fundamentally change how you age by working with your biology rather than against it.
Earle’s biological age—more than 20 years younger than her chronological age—provides living proof. When you understand your biology better and align daily habits with ancestral needs, aging transforms from inevitable decline into optimization opportunity.

The science is emerging rapidly. What seems unconventional now will become mainstream understanding—just as previous “fringe” health concepts eventually gained acceptance.
Start with one simple practice: sky before screen tomorrow morning. Your mitochondria will thank you.
