Dry January 2027: Dates, Rules and a 31-Day Plan
Dry January 2027: Dates, Rules and a 31-Day Plan
Dry January 2027 runs from Friday, January 1 to Sunday, January 31, 2027: 31 days, no alcohol. The challenge was started more than a decade ago by Alcohol Change UK, a British charity, and the only rule is full abstinence for the month. Anyone who drinks heavily every day should talk to a doctor first, because quitting cold turkey can be medically dangerous.

When Is Dry January 2027?
Dry January 2027 begins on Friday, January 1 and ends on Sunday, January 31. The month has five Fridays (Jan 1, 8, 15, 22, 29) and five Saturdays (Jan 2, 9, 16, 23, 30), so plan for five weekends' worth of social situations where alcohol would normally be present. New Year's Day falls on a Friday, so the month opens with a three-day weekend (Jan 1 to 3) while holiday plans are still running. Having a replacement drink ready before midnight on December 31 removes the decision from the moment.
What Are the Dry January Rules?
One rule: no alcohol for 31 days. Alcohol Change UK does not publish a list of sub-rules or scoring tiers. If you slip up, the month is not over. A 2016 study in Health Psychology (857 UK participants) found that people who attempted Dry January reported lower drinking and stronger drink-refusal self-efficacy at six months, even among those who did not fully complete the challenge.
"Damp January" is an informal version: cutting back instead of stopping entirely. There are no official damp-January rules, and most of the published research examines full abstinence, not partial reduction.
What Does a 31-Day Dry January Plan Look Like?
| Week | Dates | Focus | Action items |
|---|---|---|---|
| 1 | Jan 1 to 7 | Setup | Clear alcohol from the house, pick 2 to 3 replacement drinks, tell your close circle |
| 2 | Jan 8 to 14 | The first full work week | Fill the after-work slot (walk, gym, sparkling water ritual), track cravings in the Try Dry app |
| 3 | Jan 15 to 21 | Social pressure | Practice a one-line refusal ("I'm doing Dry January"), order first at the bar so you set the pace |
| 4 | Jan 22 to 31 | Finish and plan February | Note what changed (sleep, energy, spending), decide which habits to keep past January |

Does Dry January Actually Do Anything?
Short answer: the evidence is encouraging but limited. A 2025 scoping review in Alcohol and Alcoholism (Strowger et al.) screened 90 papers and reviewed 16. Among people who completed the month, it found short- and mid-term reductions in drinking, improved biological outcomes and well-being, and stronger drink-refusal self-efficacy; some benefits showed up even in people who did not fully abstain, and lighter drinkers were more likely to finish. The review also noted that nearly all existing research comes from the United Kingdom and that the topic "warrants more rigorous research."
The most-cited biomarker study is Mehta et al., 2018 (BMJ Open): 94 moderate-to-heavy drinkers who abstained for one month showed a median 25.9% drop in insulin resistance, a 6.6% median drop in systolic blood pressure, and a 1.5% reduction in body weight, compared to 47 controls who kept drinking. This was a prospective, single-center observational study, not a randomized controlled trial, and participants were self-selected, so results may not generalize to lighter drinkers.
How Many Americans Still Drink?
A Gallup survey conducted in July 2025 found that 54% of US adults say they drink alcohol, a record low for the poll. A majority (53%) said that even moderate drinking is bad for health. Among adults aged 18 to 34, the drinking rate was 50%, down from 59% in 2023. Dry January sits inside this broader shift; for the wider trend, see what sober curious means.
Who Should Not Quit Alcohol Cold Turkey?
This is the section that matters most. Alcohol Change UK warns: "People who are clinically alcohol dependent can die if they suddenly, completely stop drinking." MedlinePlus notes that withdrawal symptoms can begin within about 8 hours of the last drink and tend to peak by 24 to 72 hours. Severe withdrawal (delirium tremens) can cause seizures, hallucinations, fever, and severe confusion, and symptoms may go on for weeks.
Talk to a doctor before starting Dry January if you:
- Drink alcohol every day or nearly every day
- Have experienced shaking, sweating, or anxiety after stopping before
- Are pregnant or breastfeeding
- Take medication that interacts with alcohol
Call 911 or go to an emergency room for seizures, severe confusion, hallucinations, fever, or an irregular heartbeat during withdrawal.

Frequently Asked Questions
Does Dry January 2027 start on January 1?
Yes. January 1, 2027 is a Friday, and Dry January runs the full calendar month: January 1 through January 31. Alcohol Change UK offers its free Try Dry app for tracking, but the challenge itself is simply 31 consecutive days with no alcohol.
Can you drink non-alcoholic beer during Dry January?
Alcohol Change UK's rule is no alcohol for the month. Some drinks sold as non-alcoholic still contain a small amount of alcohol, so check the ABV on the label and decide whether it fits your version of the month. For more on what counts, see is non-alcoholic beer bad for you.
Do you lose weight during Dry January?
Some people do. In the Mehta 2018 study, participants who abstained for one month saw a median 1.5% reduction in body weight. That figure comes from moderate-to-heavy drinkers at a single center, so lighter drinkers may see less change. It is a study average, not a promise.
What is Sober October?
Sober October is the same idea in a different month: 31 days without alcohol in October. See the Sober October guide for dates, differences, and overlap with Dry January.
Is there a Dry January app?
Alcohol Change UK offers the Try Dry app for free, and the charity says it can "double your chance of an alcohol-free month." For a broader look at tracking options, see Dry January app.
For the 3 P.M. Slump, Not the 6 P.M. Drink
A month without the after-work glass often reveals a different gap: the mid-afternoon energy dip that the evening drink used to paper over. Roon is for that 1 to 3 p.m. window, not for replacing a nightcap. Each pouch delivers 80 mg caffeine and 60 mg L-theanine, plus 25 mg methylliberine (Dynamine), which slows how the body clears caffeine. In a randomized, double-blind crossover PK study (n=12), methylliberine with caffeine cut oral clearance from 41.9 to 17.1 L/hr and extended caffeine's half-life from 7.2 to 15 hours, with no higher peak. That study used 100 mg methylliberine and 150 mg caffeine (roughly 4x and 1.9x what a Roon pouch contains), so the mechanism points in the same direction, not at the same magnitude. A 15-hour half-life is not 15 hours of energy; a single pouch is meant to carry you through roughly 6 to 8 hours of the afternoon.
Take your last pouch at least 8 hours before bed; late caffeine can undercut the sleep gains that make Dry January worth doing. Roon does not reduce drinking or cravings and is not a treatment for alcohol dependence. It is a zero-nicotine, zero-sugar caffeine pouch (contains sucralose), from $9.16 per tin. Try Roon.
