Approximately 4.2 million people in the UK claimed to abstain from drinking in January, and the official January January campaign says it is intended to "restore" people's relationship with alcohol.
So also drinking a month helps people make new habits, or is it likely to lead to a binge in February?
Some studies, which mainly concern rats, seem to be based on the idea that "dry" use causes more severe drinking.
In one study, rats were given alcohol temporarily before it was suddenly removed. When they got alcohol again, the rats drank more.
Researchers were unable to find the same effect for people when they were studying US Army workers who were forced to abstain from alcohol during initial training.
After the employees were able to drink again, they drank the same amount on average or less – although at the beginning the hardest drinkers probably drank more after abstinence.
Both of these examples look at what could happen if you forced someone to give up alcohol. But how about voluntary abstention periods? Is there any psychological effect associated with having chosen to do something?
In 2014, researchers at the University of Sussex merged with the United Kingdom for Charity Alteration (which runs the official January January campaign) to assess its success, and have since evaluated the campaign every year.
When the first study was published, the charity director who started the campaign, Emily Robinson, said: "Dry January's long-term consequences were already questioned and people ask if the month will not be free so people can swing to drink once in February.
But she said that no such effect was found.
It was also the team's latest report – 800 interviewed people who kidnapped the booze in January 2018 were on average less drinkable in August than they were before the challenge, based on the units consumed and drinking days.
Leading researcher Richard Richard Visser said half of the people surveyed then drank the same amount, 40% drank less and the remaining 10% drank more than before.
Those who drank more often were people who didn't do it by the end of the month.
Dr de Visser has found a number of other health benefits including weight loss and better sleep.
The problem is that this research is selfless, which means that the results are not always representative for all citizens.
It also had a very high rate of interruption – 2800 people participated in the study, but only 800 people continued after August.
The researchers tried to adjust it by looking at what was "missing" from the final sample – more men than women left, as well as more heavy drinkers.
But while you can adapt to gender and drinking habits, it is more difficult to adjust to less tangible things, such as what is motivated and done at all.
In this case, the researchers were able to draw conclusions about how the dry January affects people's drinking by looking at a group of people who are specifically dedicated, which may not reflect the way people respond at all.
The University of Sussex is planning further studies to investigate a representative population.
To get an idea of what is happening to the population, we can look at the sale of alcohol throughout the year – it is not an ideal event because we do not know for sure that the same month it was purchased.
Tax rates from the HM Revenue and Customs Service in December show a high sales volume followed by a large drop in January. In February sales will continue to fall, before rising again in March to December.
Sales in the rest of the year are relatively consistent.
There is little dispute about the benefits of reducing alcohol consumption (although alcohol-dependent people should seek professional help before receiving professional help). However, since trying to help reduce the overall use of human alcohol in a shameless month, the evidence is still uneven.
Most serious drinkers are likely to go through the month, and those who don't do it all the time will drink more.
But the hardest drinkers who do it and ultimately drink less are probably surprising that they also benefit the most.
They reduce alcohol consumption and see much greater health benefits.
Researchers at the University of Sussex who evaluated the study warned that this task was not suitable for people with alcohol dependence.
Maddy Lawson at Alcohol Change in the UK said: "Alcohol consumption per month is safe for most people, including major alcohol users. But if you drink heavily or regularly, you may be addicted to alcohol, and in this case you most likely need more supports to reduce. ”
For people who are not addicted to alcohol, but who are under the influence of drunkenness and "binge abstinence", some experts suggest that they might have a better chance a couple of dry days a week throughout the year.
