The Architecture of Deep Sleep: Why 8 Hours Isn't Enough

Most high-performers treat sleep as a variable to be minimized. The data suggests the opposite: sleep is the single most potent performance enhancer available to human biology.

The 4 Stages of Sleep

Understanding sleep architecture is the first step to optimization. Your brain cycles through four distinct stages every 90 minutes:

  • Stage 1 (NREM): The transition phase.
  • Stage 2 (NREM): Light sleep where memory consolidation begins.
  • Stage 3 (Deep Sleep): Physical restoration and growth hormone release.
  • REM Sleep: Cognitive processing and emotional regulation.

Why Magnesium Matters

Magnesium Bisglycinate, a key component of our Sleep & Restore protocol, has been shown to activate the parasympathetic nervous system, helping you transition into Stage 3 deep sleep faster and stay there longer.
