The Health Map for Sleep

A Health Map is the navigation layer above the Topics. It shows the full path, the cross-area benefits, common mistakes, the contexts in which it applies, where experts disagree at the area level, and what is changing now.

Melatonin dosing: low-dose precision versus higher-dose convenience

Mainstream: Effective melatonin doses are typically 0.3 to 3 mg — the dose that mimics endogenous production and shifts circadian timing without producing next-day grogginess. Higher doses (5 to 10 mg, common in US over-the-counter products) don't work better.

Contested: Some popular framings recommend higher doses or claim broader sleep-aid uses; commercial products are typically sold at doses well above the validated range.

What survives: Start low (0.3 to 1 mg) for circadian-rhythm uses (jet lag, shift work, delayed sleep phase). Higher doses don't improve sleep onset and often worsen morning grogginess. Melatonin is not a sedative — for general sleep complaints, address the basics first.

The full Roadmap applies this pattern across every area-level tension. Path, Mistakes, Context, and What's changing now follow the same approach.
