Slow Wave Sleep (Deep Sleep) Enhancers

The Physical Repair Phase

Stage 3 NREM (Slow Wave Sleep) is where physical restoration happens. 95% of daily Growth Hormone (HGH) is released during this phase. If you wake up physically sore and exhausted, you are likely missing SWS.

Inhibitors vs. Enhancers

• Inhibitors: Late meals (insulin blunts HGH), Alcohol (fragments SWS), and Heat (prevents entry).
• Enhancers: A cold room (18°C), Glycine (3g), and L-Ornithine (400mg) have been shown to reduce cortisol and improve SWS duration.
