The Dry January Effect

Research that backs it up...
Richard de Visser, a psychology professor at the University of Sussex in England, has done several studies examining Dry January.
Working with Alcohol Change UK, he surveyed 857 people who signed up to participate before and after the campaign, and again six months later. Two-thirds of the participants reported that they successfully met the challenge. He published his 2016 study in the journal Health Psychology.
A small group of participants experienced a rebound effect, drinking more than they drank before, Dr. de Visser says. But overall, at the six-month follow-up mark, participants who finished Dry January and those who quit early reported drinking fewer days a week and fewer drinks per sitting on average. (Those who finished saw greater decreases.) Both groups also reported getting drunk less.
A group of liver specialists found that abstaining from alcohol for a month improved liver function, blood pressure and markers associated with cancer. Participants also lost an average of 3.3 to 4.4 pounds, says Rajiv Jalan, a professor of hepatology at University College London and co-author on the study. (He practices Dry January himself.)
The study was published by in the journal BMJ Open in April. It compared 94 moderate-to-heavy drinkers opting to go dry for a month and compared them with 47 control participants who drank as normal.
In another study funded by the BBC and expected to be published this year, Dr. Jalan and co-researchers assigned 20 participants to abstain from alcohol for a month and instructed 10 to continue drinking as usual.
Three weeks after the dry month, the heavier drinkers had halved their alcohol consumption, Dr. Jalan says. Those who gave up drinking for a month had better liver function, lost an average of four pounds and reported better concentration, sleep, ability to exercise and less fatigue.
Ms. Molnar says better sleep is among her favorite things about going dry every January.
“You wake up more refreshed,” she says.
Indeed, sleep experts say alcohol, despite its reputation as a sedative, has a negative effect on sleep quality. Numerous studies have demonstrated this.
A study published in 2018 in the journal JMIR Mental Health found that even one drink impaired sleep quality, as measured by the heart rate variability of more than 4,000 people.
Though alcohol can induce slow-wave sleep, the deepest phase of sleep, in the beginning of the night, it reduces it later on, says Doug Kirsch, medical director of sleep medicine at Atrium Health in Charlotte.
“After a couple of hours, people will start waking up and your sleep is more fragmented,” says Dr. Kirsch, who says alcohol can also make snoring and sleep apnea worse.
Not everyone champions the concept of Dry January.
In a 2016 issue of BMJ, two experts debated its pros and cons. Ian Hamilton, an associate professor of addiction at the University of York, took the con side.
“I think it would be better if people had regular breaks, not binge breaks,” he says.
He also notes that an abrupt withdrawal from alcohol for excessive drinkers can be life-threatening.
“Over 800 people died of alcohol withdrawal in 2016,” says George Koob, director of the National Institute on Alcohol Abus
