Here's what's actually happening inside your throat the moment you fall asleep.
After 40, two things happen simultaneously: soft tissue quietly builds up around your neck and throat, and the muscles holding your airway open begin to lose tone — like any muscle that isn't being trained. More tissue pressing down. Weaker muscles holding it up.
The moment you lie flat, gravity pulls all of that relaxed tissue directly into your airway. Air forces through a partially collapsed tube. That violent vibration is the snore. And every partial collapse starves your brain of oxygen. That's the exhaustion. That's the fog. That's the Gravity-Age Trap.
