How to Use This Sleep Quality Hub
Use this hub for restorative-sleep and next-day-recovery questions, not just falling asleep faster. The most useful pages connect a mechanism (cortisol, GABA, circadian) to a realistic outcome and note whether the evidence is direct sleep data or inferred.
Choose by fit
- Separate sleep-onset aids from sleep-depth and recovery support; they are studied differently.
- Prefer pages that explain the mechanism (cortisol blunting, GABA-A modulation, adenosine) rather than generic "relaxation" claims.
- If daytime function is impaired despite adequate time in bed, a clinical sleep evaluation comes before supplement stacking.
Safety first
- Review interactions with sedatives, antidepressants, and blood-pressure medication before use.
- Start with single agents so effects and side effects can be attributed.
- Do not substitute supplements for evaluation of a suspected sleep disorder.
