The Science of Core Sleep: Why It’s Your Secret Weapon
You’ve heard of REM sleep, but core sleep—the combined deep (slow-wave) and restorative stages—is where the magic happens. This phase repairs tissues, consolidates memories, and resets your stress hormones.
Without enough core sleep, even 8 hours in bed can leave you feeling like a zombie.
Modern life throws two punches at core sleep:
Circadian rhythm misalignment (thanks to screens and erratic schedules).
Fragmented sleep (waking up constantly due to temperature swings or noise).
The result? You’re stuck in a loop of “I fell asleep, but why do I still feel exhausted?”
The fix isn’t willpower. It’s hacking your biology.
