What is DEEP_MAINTENANCE?
DEEP_MAINTENANCE is the ONDA concept for the deep sleep phase when glymphatic clearance is maximally active. The system performs critical "maintenance" — clearing metabolic waste, consolidating memory, and repairing tissue.
Requirements
- •Temperature drop — core body temperature must decrease 1–2°C
- •Insulin absence — no caloric intake 3–4 hours before sleep
- •Sleep architecture — sufficient slow-wave sleep (N3) duration
- •Quiet environment — uninterrupted sleep for full cycles
In ONDA Life
The Glymphatic Flush article covers Thermal Flush, Dietary Firewall, and sleep posture protocols for DEEP_MAINTENANCE optimization.
