How to Get a Healthy, Chemical-Free Tan This Summer
Good day, Viva Family
Ever wonder why your great-grandmother could spend all day working in the garden without burning, but you can barely make it through a beach day without looking like a lobster?
Here's the thing the $47 billion sunscreen industry doesn't want you to know: Your body already has the most sophisticated sun protection system on the planet. It's called melanin. And it works better than anything you can buy in a bottle.
But somewhere along the way, we forgot how to use it.
We've been told the sun is our enemy. That our skin is fundamentally broken. That we need chemical cocktails just to survive summer. Meanwhile, our ancestors lived outdoors for millennia without a single case of melanoma.
So what changed?
In this article, we’ll explore the science-backed approach to tanning that uses the sun’s timing, natural supplements, cold exposure, and light discipline to help your body build a healthy glow, without the damage.
🔆 Melanin: Nature’s Sunscreen
Before we jump into the how-to, let's talk about what's actually happening when you tan.
Your skin contains specialized cells called melanocytes that produce melanin, nature's original sunscreen.
There are two types of melanin working in your skin:
- Eumelanin - the dark, protective type that offers serious UV protection.
- Pheomelanin - the lighter type that provides less protection
Here's the thing: When you gradually expose your skin and eyes to UVB rays, your melanocytes crank up eumelanin production. This creates what scientists call a "solar callus" - a thicker, more protective skin layer that naturally filters UV radiation.
Translation: Your body builds its own sunscreen. From the inside out.
🧪 Study Highlight: A 2008 study in Photochemistry and Photobiology proved that UVB radiation specifically triggers Eumelanin production and provides significantly higher antioxidant protection than any topical product.
Your ancestors knew this. They lived outdoors for millennia without a single case of melanoma. So what changed?
Timing Is Everything: The Art of Strategic Sun Exposure
Most people think tanning means lying in the sun at noon until they're crispy. Well, that's not tanning. That's damaging your skin.
Smart tanning is about working WITH your circadian rhythm, and WITH nature.
Morning UVA (8-10 AM): The Preparation Phase
Start your day with gentle UVA exposure. This isn't intense enough to burn, but it's crucial for:
- Activating nitric oxide production
- Stimulating early melanin activity
-
Preparing your skin for stronger UV later
☀️ Strategic UVB (10:30 AM - 12:30 PM): The Building Phase
This is your melanin-building window. After your morning UVA prep, your skin is ready to handle moderate UVB exposure without burning.
The key is gradual progression.
Start with 10-15 minutes. Build slowly. Let your "solar callus" develop naturally. To learn more, check now in our blog How to Sunbathe Responsibly (and Powerfully) This Summer.

🧪 Human Experiment: A 2015 German study found that subjects who gradually increased morning sun exposure over 14 days showed increased melanin index and lower inflammatory markers compared to those exposed randomly throughout the day.
☀️ Sunset Light: The Recovery Phase
Don’t skip the golden hour. Sunset light is rich in infrared (IR) and red wavelengths, which:
- Reduce inflammation
- Enhance mitochondrial repair
- Signal the body to wind down, increasing melatonin production
Watching the sunset helps your skin recover from the day’s UV exposure while priming your body for deep sleep and nighttime autophagy.
The Cold Exposure Game-Changer
Here's where it gets interesting...
Recent research has uncovered something remarkable: Cold exposure before sun exposure can actually supercharge your tanning response.
When you hit cold water for 2-3 minutes, your body activates brown adipose tissue (BAT). This shares genetic pathways with melanocyte function and boosts α-MSH - your melanocyte-stimulating hormone.
A 2023 study published in MDPI confirmed that cold pre-conditioning literally primes your skin to handle UV radiation while increasing melanin activation.
The protocol is very simple:
💛 2-3 minutes cold shower or plunge
💛 10-30 minutes strategic sun exposure
💛 Watch your skin respond like never before
🧪 Animal Study: Mice exposed to cold temperatures for 10 minutes per day over 7 days showed a significant upregulation in melanin biosynthesis enzymes and α-MSH signaling pathways compared to control mice.
The "Internal Sunscreen" Most People Ignore
While your body has everything it needs to tan naturally, certain nutrients can amplify the process:
1) Astaxanthin - This antioxidant doesn't just protect against UV damage. It increases your skin's UV tolerance. A double-blind study found people taking 4mg daily for 9 weeks had significantly less UV-induced skin damage.
2) Carotenoids - Beta-carotene from carrots, lycopene from tomatoes. These literally change your skin's composition from the inside. One study showed people consuming lycopene-rich tomato paste for 12 weeks had 33% more natural sunburn protection.
3) Coconut Oil - Pure coconut oil provides natural SPF 4 while keeping skin hydrated and reducing oxidation.
4) Zinc Oxide - Look for natural sunscreens made with zinc oxide as the active ingredient - they're widely available and work far better than chemical alternatives. Use them on sensitive areas (nose, lips, shoulders) when you need extra protection during longer exposures.
No synthetic chemicals. No hormone disruption. Just natural protection working with your biology, not against it.
The Hidden Enemy: How Artificial Light Is Sabotaging Your Tan (This Will Shock You)
Here's the part that might completely change how you think about tanning: The artificial light in your home is systematically destroying your skin's ability to tan. Every LED bulb. Every phone screen. Every computer monitor.
They're all pumping out blue and green wavelengths that sabotage your skin in two ways:
1. Melatonin Destruction = No Skin Repair
Melatonin isn't just for sleep. It's one of your skin's most powerful repair hormones. It regulates melanocyte function, controls mitochondrial repair, and acts as a potent antioxidant against UV damage.
When artificial light hits your eyes after sunset, it tells your brain "keep making stress hormones, stop making melatonin." Your skin can't repair from UV exposure.
Result: patchy tanning, increased burning, slower melanin development.
2. Autophagy Shutdown = Toxic Buildup
Autophagy is your cellular cleanup crew. It removes damaged proteins, clears oxidative debris, and maintains healthy pigmentation. Autophagy only happens in darkness. When you expose yourself to artificial light at night, you literally shut down this repair process.
A 2017 study in the Journal of Investigative Dermatology found that people exposed to light at night showed accelerated skin aging, increased inflammation, and irregular pigmentation patterns.
☀️ Your Complete Natural Tanning System

- Avoid wearing sunglasses- This is the direct reason to sunburn (learn more)
✨ Daily Nutrition:
- 4mg astaxanthin
- Carotenoid-rich foods
- Quality fats for hormone production
🌙 Evening Routine:
- Replace LED light with low amber lighting such as Himalayan salt lamps.
- Wear your VivaRays Evening Circadian glasses after sunset.
- Switch to VivaRays Nightime Circadian glasses 1 hour before bedtime
- Dark, cool bedroom for optimal sleep
🗓️ Weekly Progression:
- Increase exposure 2-3 minutes per week

☀️ Conclusion ☀️
Your body knows how to protect itself from the sun. It's been doing it for millions of years.
The problem isn't your biology. It's modern life interfering with biological processes that used to happen automatically. Fix the interference. Optimize the inputs. Trust the system.
This summer, instead of slathering chemicals on your skin and hoping for the best, why not use the protection system you were born with?
Your skin will thank you. Your sleep will improve. Your energy will increase.
And yes, you'll develop the kind of deep, even, protective tan that actually makes you healthier instead of just temporarily darker.
The choice is yours.
With Love 💛 and Light ☀️
