Cortisol Face vs. Testosterone Glow: The Sleep Connection

High cortisol causes "moon face" and destroys collagen. Learn how to crush cortisol and spike testosterone overnight.

The "Moon Face" Epidemic

Waking up puffy? That's likely cortisol. High stress levels cause water retention and bloat, masking your bone structure. Conversely, high testosterone promotes bone density and a lean, angular look.

High Cortisol

  • • Water retention & puffiness
  • • Collagen breakdown
  • • Acne & inflammation

High Testosterone

  • • Lean facial structure
  • • Clear, thick skin
  • • "The Glow"

Crashing Cortisol with Sound

You can't just "relax" on command. But you can use entrainment. SleepHack's "Wind Down" mode uses Alpha-Theta beats to physically lower your heart rate and flush cortisol before you even sleep.
