Why We Exist

The internet has a health information problem.

Search any health topic and you'll find thousands of articles — most of them recycled, unverified, or driven by product sales. Wellness influencers claim what feels true. Supplement brands fund their own studies. Your doctor doesn't have time to explain the full picture.

The result? Millions of people making life-altering health decisions based on information that was never tested, never reviewed, and never proven.

We saw this gap. And we built AETERNA to fill it.

Every piece of content we publish is rooted in peer-reviewed science — from institutions like Harvard Medical School, Stanford, and NIH, published in journals like Nature, Cell, and The Lancet. We translate that science into plain English. And we cite every single claim with a DOI.

So when your doctor asks where you read something, you don't say "the internet." You say the study name, the institution, and the year it was published.

The Problem
The internet is the world's largest health misinformation machine. No peer review. No sources. No accountability.
The Gap
Academic journals exist — but they're written for scientists. Nobody was translating them for the rest of us.
Our Answer
AETERNA is the voice of longevity science — peer-reviewed research, made beautiful and accessible for the US and UK reader.
Our Promise
Sources, not opinions. Every claim links back to a published, peer-reviewed study. Always.
Our Vision
To become the most trusted longevity media brand on earth — the Vogue of evidence-based health.

Protocol Library

What To Actually Do

01
Sleep
Fixed schedule, 7–9 hours, dark and cool room, morning daylight. The foundation everything else is built on.
Read protocol →
02
Movement
Walk 7–10k steps daily, lift 2–3× a week. Aerobic volume plus strength is the evidence-backed combination.
Read protocol →
03
Nutrition
Plant-forward, minimally processed, modest portions, eaten in community. Mediterranean pattern, RCT-validated.
Read protocol →
04
Connection
Prioritise close relationships and show up consistently. 85 years of Harvard data rank it above diet and wealth.

Myth vs Evidence

What the Science Says

The Claim
"Intermittent fasting is the best diet for a longer life."
Overstated
960-mouse Jackson Laboratory study: calorie restriction, not meal timing, drove the longest lifespans.See the study →
The Claim
"Diet and exercise matter more than sleep."
False
2025 research: insufficient sleep cuts life expectancy more than diet, exercise, or social ties combined.See the study →
The Claim
"Telomere shortening can never be reversed."
Outdated
A 2025 clinical trial recorded measurable telomere lengthening from a common SGLT2 diabetes drug.See the study →
The Claim
"BMI is the best measure of your health risk."
Misleading
Grip strength and muscle mass outpredict BMI, cholesterol and blood sugar for mortality after 50.See the study →

Relationships

Connection Is a Longevity Drug

85 years of Harvard data show the quality of your relationships predicts how long and how well you live — more than diet, wealth, or genes. Loneliness raises mortality risk on par with smoking.
