EXPERIMENTS › SLEEP › NO ALCOHOL VS BASELINEONE OF 21 COMPARISON PAGES · RENDERED FROM THE CATALOG + EDITORIAL DATASET

Does no alcohol actually improve sleep?

A nightcap feels like it helps you sleep — but it's one of the best‑documented disruptors of sleep quality. This is a behavior experiment, and the data often surprises people.

1–10 SUBJECTIVE RATINGONE VARIABLENULLS REPORTED

THE COMPARISON — ONE VARIABLE CHANGES

A · NO ALCOHOLThe nights with no alcohol. Everything else in your routine stays exactly as it normally is — one variable is what makes the difference readable.

B · BASELINEYour normal nights, nothing changed. These are the control your no alcohol nights are measured against.

Everything else stays as normal — one variable is what makes the difference readable.

WHAT THE RESEARCH SAYSAlcohol speeds sleep onset but suppresses REM and fragments the second half of the night, lowering restfulness even when total time looks fine.Effects vary by amount, timing, and person — so a two‑week alcohol‑free vs normal comparison on your own deep sleep and HRV is uniquely convincing.

01Rate one thing. Each morning: your sleep, 1–10. Five seconds. Subjective on purpose — it's your outcome, not a wearable's.

02Context rides along. Sleep duration and screen time from Apple Health / Health Connect add context if you connect them. Optional, never required.

03A verdict that admits uncertainty. Likely helped · no clear difference · likely made it worse — with how confident, not just which. Too few clean days? The app says so instead of rounding up.
