You don’t have one body clock — you have many, and different habits move different ones. Here’s which circadian levers actually shift your sleep timing, which only affect metabolism, and why most advice conflates the two.
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 onset requires three simultaneous conditions: sufficient adenosine (sleep pressure), correct circadian timing, and absence of arousal signals. Most sleep onset problems are caused by one or more being unmet. This guide covers the neuroscience, the paradoxical intention technique, stimulus control, cognitive shuffle, physiological sigh, the Glycine + L-Theanine + Magnesium Glycinate supplement sequence, and what makes sleep onset worse — including clock-watching and lying awake in bed.
Sleep has a structure, not just a duration. What happens across the stages and cycles of a night, why the shape isn’t symmetrical, what slow-wave sleep does for memory, and an honest look at the claims wearables and headlines get wrong.
The first hour after waking sets your whole day. A morning routine built on the actual science — light, the cortisol awakening response, hydration and movement — plus the right order to do it in.
