Is Sunscreen Necessary for Humans? Here's the Truth

Sunscreen has been branded as a daily essential—almost as important as brushing your teeth. We’re told it prevents cancer, protects our skin, and keeps us youthful. But is sunscreen necessary for humans… or is it just a modern solution to a modern problem?

Let’s break this myth wide open.

We Evolved Under the Sun—So Why Are We Scared of It?

For millions of years, our ancestors lived, hunted, and thrived in the sun. They didn’t have SPF 50 or Banana Boat spray. What they did have was:

• Skin built by real food—animal fat, collagen, and nutrients

• Strong sun habits—early morning exposure, movement, shade when needed

• Zero seed oils, no ultra-processed food, and no chemical-laden skincare

Sunlight wasn’t the enemy. It was—and still is—a biological requirement.

So, how did we get to this point? Where is sunscreen marketed as a must-have for survival?

Is Sunscreen Necessary for Humans, or Is Skin Cancer Caused by Lifestyle?

If you're asking yourself, “Is sunscreen necessary for humans?”, the answer depends on your metabolic health, not the sun itself.

Modern science wants you to believe that UV rays are the sole cause of skin cancer. That’s like blaming water for drowning without ever questioning whether the swimmer had a life jacket.

The real issue? Our biology has become weak. Our cells are built from seed oils, sugar, and synthetic garbage. So when UV light hits that inflamed, oxidised tissue—yes, damage happens.

But it’s not the sunlight’s fault.

If your body is made of garbage, sunlight becomes a threat if your body is built like your ancestors’—with nutrient-dense, animal-based fuel—sunlight becomes a signal for strength, hormone production, and healing.

But What About the Science? Let’s Talk Nambour

Sunscreen advocates often point to one trial as “proof” it prevents cancer: the Nambour Trial in Australia. It’s been cited endlessly, but most people have never actually read it.

So I did.

And here’s what the sunscreen industry doesn’t want you to know:

🧪 Key Criticisms of the Nambour Trial

1. The “50% Melanoma Reduction” Wasn’t Statistically Significant

The hazard ratio for melanoma was 0.50—but the P-value was 0.051. That means it just barely missed statistical significance. Translation?It doesn’t count.

2. Melanoma Was a Secondary Endpoint

The trial wasn’t even designed to study melanoma—it was a side effect of looking at other skin cancers. That opens the door to random chance and weaker conclusions.

3. Wide Confidence Intervals = Low Certainty

The margin of error for the melanoma result stretched from 0.24 to 1.02. That’s a massive range. In plain English: we’re not really sure what happened.

4. The Sample Size Was Tiny

Only 33 melanomas occurred in total over the multi-year study. That’s not enough data to draw hard conclusions for an entire population.

5. The Results Only Apply to High-UV, Fair-Skinned Australians

This was a narrow study in one unique group. It doesn’t apply to darker-skinned populations, northern climates, or… well, most of humanity.

6. It Only Reduced One Type of Skin Cancer

It showed a modest reduction in squamous cell carcinoma (SCC), but no benefit for basal cell carcinoma (BCC)—the most common skin cancer.

7. Real-World Sunscreen Use Isn’t Represented

Participants used sunscreen daily and rigorously, under research supervision. That’s not how anyone uses sunscreen in real life.

8. Even the World Health Organisation wasn’t Convinced

The IARC (World Health Organisation) said in 2001 that there’s “insufficient evidence” that sunscreen prevents melanoma or BCC. Only “limited evidence” for SCC.

The Truth? Sunscreen Isn’t the Hero—Your Lifestyle Is

If you eat fake food, live under fluorescent light, sleep poorly, and then lie in the sun for 4 hours… of course you’re going to burn and blame the sun.

But if you build your body with:

• Grass-fed animal fat

• Organ meats

• Minerals and collagen

• Early morning sun exposure

• Strong circadian rhythms

…then sunlight becomes your ally, not your enemy.

Final Word: You Don’t Need to Fear the Sun

Sunscreen is not evil. But it’s not essential, either. Especially not the chemical-laden products full of hormone disruptors and synthetic preservatives.

If you’re metabolically broken, sunscreen might help you avoid a burn. But if you’re living in alignment with how humans are meant to live—clean diet, movement, sun adaptation—you may never need it.

Build solar resilience from the inside out.

That’s the ancestral way.
