Overview
- A systematic review in Alcohol and Alcoholism pooling 16 studies and more than 150,000 participants reports better sleep, mood, blood pressure, liver markers and modest weight loss after a month without alcohol.
- Researchers and campaign data indicate that registration, tracking apps, daily motivational messages and online communities substantially raise the odds of completing the month and support lower drinking afterward.
- Clinicians caution that people with heavy dependence should not stop drinking abruptly without medical supervision due to potentially life‑threatening withdrawal risks.
- Survey findings show many participants slip in the first week and only a minority finish the month alcohol‑free, prompting pragmatic tips and flexible options such as “Damp January.”
- Market signals reflect a cultural shift as Gallup reports the lowest share of U.S. adults drinking on record, NIQ finds Dry January boosts non‑alcoholic sales, and consumers increasingly alternate between alcoholic and zero‑proof drinks.
