Why sleeping past midnight accelerates
biological aging — and how to fix it
Circadian timing matters as much as sleep duration. Going to bed after midnight compresses your slow-wave sleep, elevates cortisol, and accelerates cellular aging — even if you're getting 7 hours. Here's what the science says and how to shift your sleep phase earlier.

What is longevity medicine? A plain-language introduction
Longevity medicine isn't about looking younger or living forever — it's about extending the years you spend in good health, not just the years you're alive. Here's what that actually means.

Biological age vs. chronological age: what's the difference?
Your birth certificate gives you one number. Your body may be running faster or slower than that — and unlike your calendar age, your biological age is at least partly within your control.

What to expect from a longevity doctor (and how it's different)
A first visit with a longevity doctor doesn't look like a typical check-up. Here's what actually happens — from intake to an ongoing, tracked plan built around your own data.

The 8 domains of longevity, explained
Your Aevum Protocol assessment covers 8 core domains of longevity. What each one measures, and why they matter together rather than in isolation.

How is biological age actually calculated? A look at the main methods
Biological age isn't one test — it's several different methods, each with its own accuracy trade-offs. A plain-language look at the main approaches, and why Aevum Protocol's own Biological Age feature is built on PhenoAge.

The sleep conditions quietly shortening your healthspan
Sleep apnea, chronic insomnia, circadian disorders, and chronic short sleep aren't just uncomfortable — they're independent, measurable drivers of biological aging, and most go undiagnosed for years.

Sleep Architecture: What Actually Happens While You Sleep
Total hours only tells part of the story. What each sleep stage actually does, why the brain's waste-clearance system works hardest during deep sleep, and why losing the right stage matters more than losing the same hours a different way.

Sleep Duration and Longevity: How Many Hours Actually Matter
The relationship between sleep and mortality is U-shaped, not linear — both short and long sleep carry higher risk. Why 7 hours, not 8, shows up as the lowest-risk point in the largest studies.
