Your Body Is Begging for Darkness (And Science Finally Knows Why)
It's 5:00PM, and the sun is already setting.
You feel it immediately, that sinking dread. "No, not again."
Every day, the sun sets a little earlier. Every day, that darkness comes a little sooner.
And as the days get shorter and colder, you feel the winter blue- low energy, low mood, brain fog, and cravings you can't explain.
And you think: "What's wrong with me? Why can't I handle winter?"
Why 38% of Americans Experience Winter Depression (And How Darkness Is the Cure)
Research shows 38% of Americans, over 100 million people, experience a declining mood during winter. The exhaustion, the depression, the fog. It's an epidemic.
But here's what I discovered after years of this same struggle:
The problem isn't you.
The problem isn't winter.
The problem is that you're fighting against something your body desperately needs.
The Groundbreaking Study That Revealed Darkness as Medicine
In the early 1990s, psychiatrist Dr. Thomas Wehr had a radical idea: What happens when modern humans stop fighting darkness?
He took volunteers struggling with winter depression and exposed them to 14 hours of darkness every single night. No phones. No TV. No artificial light. Just darkness from 6 PM to 8 AM.
The first nights were uncomfortable. But after a few weeks….
Their bodies completely transformed.
Their melatonin production stretched to 12-13 hours (versus the 7-8 hours most of us get). But here's what stunned everyone:
These people, who entered the study depressed and exhausted, described feeling more restored and clear-headed than they had in years. Their depression lifted. Their energy returned.
When they stopped fighting darkness and embraced it, their bodies remembered how to heal.
This discovery led to one question: What's actually happening in darkness that's so powerful?
Ancient Cultures Used Darkness as Natural Medicine for Thousands of Years
For thousands of years, cultures worldwide didn't just tolerate winter darkness—they honored it as sacred healing time.
The ancient Egyptians built healing temples in complete darkness where people would sleep for days to cure illness. They called darkness "the womb of regeneration."
Nordic peoples celebrated the winter solstice—the longest night—as their most sacred night, when healing was most powerful.
Indigenous cultures from the Arctic to the Amazon saw winter's darkness not as something to fear, but as a gift—when earth and all creatures rest, restore, and renew for spring's rebirth.
They didn't know about melatonin or mitochondria or cellular regeneration. But they saw the results. They witnessed what happened when people honored winter's darkness versus fought against it.
They understood that nature designed a perfect balance: long summer days for energy and activity, long winter nights for deep healing and regeneration.
Dr. Wehr's experiment simply proved what they already knew.
So if this healing system is built into us, and ancient cultures knew how to access it, why do so many modern people struggle so terribly in winter?
Because we've forgotten the most fundamental truth about winter
When Darkness Means Rebirth
Winter is not a season of death. It is a season of intentional stillness.
A temporary death that makes space for your rebirth. This is when your body enters its deepest restoration of the entire year, preparing you to rise into spring feeling renewed, vital, and fully alive
Look at nature. Everything around you symbolically 'dies' in winter.
The grass disappears. The leaves decay and return to the soil.
Animals withdraw, hibernate, and slow down.
Movement softens. Life turns inward.
And then , without fail , it all springs back into color, growth, and vitality.
None of this is random.
It is a perfectly programmed biological cycle that begins the moment the days grow shorter and darkness prevails.
This increase in darkness activates the great yin of nature ,melatonin , which rises to guide repair, regeneration, and deep inner renewal.
But this natural cycle only unfolds when you stop extending your day artificially with screens, LEDs, and indoor lighting.
Artificial light tricks your brain into thinking it's still summer at 10 PM, shutting down melatonin and robbing your body of the winter restoration it is designed for.
Winter is an invitation.
To surrender.
To restore.
To let parts of you 'die' so a more vibrant version of you can be born in spring.
And this isn't just poetic metaphor. This death and rebirth happens literally, at a cellular level, every single night
The Science of Melatonin: Your Body's Master Healing Molecule
Here's what's actually happening inside your body every time darkness falls:
Your pineal gland begins releasing melatonin, a molecule most people still believe is "just for sleep."
But melatonin is far more than a sleep hormone.
Melatonin is the most powerful antioxidant your body produces.
Each molecule can neutralize up to 10 inflammatory free radicals, far surpassing dietary antioxidants like vitamin C or E.
And melatonin's role goes even deeper.
It is the master switch that activates your body's nightly cellular cleaning systems:
-
Autophagy : clearing out damaged cells and proteins
-
Apoptosis : removing dead cells and replacing them with brand new healthy ones
-
Mitophagy : recycling and repairing old dysfunctional mitochondria
Every single night, 50–70 billion cells in your body are designed to die and be replaced with fresh, healthy ones. That's a billion with a B.
Your body literally rebuilds itself in darkness.
And here's the part that changed how I see winter: As days get shorter and darkness increases, your body is designed to produce MORE melatonin.
The Devastating Effects of Light Pollution on Your Winter Health
Think of your body like a house. If you never take out the trash, it piles up until your home becomes cluttered, dirty, and toxic.
That's exactly what happens to your cells without proper darkness at night.
When this cellular cleaning doesn't happen, you feel it:
- Crushing fatigue no matter how much you sleep
- Mood swings and irritability
- Uncontrollable cravings and weight gain
- Chronic inflammation and aches
- Weakened immunity
But when melatonin rises properly in darkness and the cleaning crew shows up?
- You wake up actually refreshed,not hitting snooze five times.
- Your energy is stable all day long, not crashing at 2 PM.
- You're in a genuinely good mood.
- Your appetite is naturally controlled.
- Your immune system is stronger.
In less than a week of proper darkness, you could have completely fresh mitochondria powering every cell in your body.
This is your body working exactly as it was designed to work.
And keep in mind: as melatonin rises and your body shifts into its repairing state, it's completely natural to feel the yin aspect of yourself awakening.
You'll still have energy , but its texture becomes softer, steadier, more inward.
It's a different quality than the bright, fiery energy of summertime.
This isn't laziness, depression or "low motivation." It's the natural winter state : the inward, restorative polarity that balances the outward summer drive..
Don't resist that natural pull toward rest.
When you honor this softer rhythm, your body can heal, regenerate, and rebuild at a level that simply isn't possible when you keep pushing against winter's design.
Why Modern Lighting Destroys Your Circadian Rhythm and melatonin production
But here's the heartbreaking truth:
Everything your body is designed to do in winter, the deep repair, the renewal, the inner reset, depends on one thing modern humans almost never experience anymore: Actual darkness AKA no artificial lights at night
Because while your biology is trying to slip into its ancient winter rhythm…
Modern life is fighting against it
Here's what's actually happening in most homes the moment the sun sets:
We declare war on darkness. Overhead LEDs blazing. Screens everywhere. Light flooding every corner.
Let me show you something shocking:
Your home is literally a thousand times brighter than anything humans experienced after dark.
Think about the mixed signals your body receives:
Your pineal gland is supposed to sense the darkness and fire the order: "Release melatonin! Start healing!"
But your eyes see blazing light: "It's daytime! Stay alert! Block melatonin!"
So even though you sleep 8 hours, melatonin never fully rises.
The cellular cleaning crew never shows up. Those 50 billion cells that should regenerate? They don't. The inflammation that should clear? It stays. The mitochondria that should renew? They stay exhausted.
You wake up feeling like you never slept. Because at a cellular level, you didn't.
And when our melatonin cycle gets messed up, our body loses its sense of the seasons. It's like turning night into day and winter into summer.
That throws off our body's natural healing and rejuvenating abilities, leaving us feeling drained and down.
This is why 100 Million American feel terrible in winter. This is why SAD affects 16 million people. This is why you're exhausted despite sleeping enough.
Your body is trying to heal you. Modern life is blocking the signal.
We've lost the balance. We're drowning in light and starving for darkness.
Your 5 steps to Honor Darkness This Winter
Step 1: Protect Your Melatonin After Sunset
The moment the sun sets, your body is ready to start producing melatonin.
Put on VivaRays Evening Lenses. These filter the specific blue and green wavelengths that block melatonin production.
You can still use your phone, watch TV, live your life—while your body produces melatonin naturally, as if you were sitting by a warm fire.
Step 2: Create Your Evening Sanctuary : Opt for natural sources of light like fire, candles, and salt lamps after sunset. These sources emit healing infrared light, which is absent in modern light bulbs.
Step 3: Deepen the Signal Before Bed One hour before sleep, clip on VivaRays Red Nighttime Lenses. This is maximum protection, your body ramps melatonin to peak healing levels.
Step 4: Sleep in Complete Darkness Blackout curtains or a sleep mask. Remove all light sources. Keep your room cool. This is when those 50 billion cells regenerate, when inflammation clears, when your body does what it was designed to do.
Step 5: Keep your bedroom free from wifi and phone signals: Wifi and phone signals operate at a light frequency called microwave, which can disrupt melatonin production. Transform your bedroom into a sanctuary space by turning off the wife, eliminating electronic devices and creating a calm, soothing atmosphere conducive to restful sleep.
The Choice
"Light drives evolution and energy. Darkness drives regeneration and repair."
You need both. Nature designed the perfect balance: Long summer days for activity. Long winter nights for healing.
We've just forgotten how to honor it.
Let darkness be what it's always been: Your body's most powerful healing force.
