Poor sleep is the most reliably documented impairment to cognitive performance available — and the most commonly ignored one. This guide covers the evidence-ranked sequence for tonight: environmental interventions first (largest, fastest, free), timing changes second, then supplementation — Magnesium Glycinate, Glycine, L-Theanine, and the pre-formulated Performance Lab Sleep option — all within the NeuroEdge 90-60-30 wind-down protocol.
Sleep is not a passive recovery state — it is the most sophisticated memory consolidation process the brain deploys. Understanding sleep architecture — the four stages, their specific memory functions, and the physiological triggers that determine stage distribution — is the difference between sleep hygiene as generic advice and sleep optimisation as a precision protocol. This guide covers the N3 slow-wave mechanism for hippocampal-cortical memory transfer, what destroys it, and the 90-60-30 protocol that systematically addresses every major architectural disruptor.
Most sleep advice focuses on duration. The research is clear that architecture matters more — specifically the proportion of slow-wave and REM sleep relative to total time in bed. The complete evidence-based protocol for improving sleep quality from the ground up: environment, timing, temperature, wind-down sequence, and targeted supplementation.
