Those who imbibe alcohol in excessive amounts should be familiar with the concept of Dry January. The idea is a temporary break from drinking alcohol for the full 31 days of January. This is in an attempt to break away from the ill health effects of alcohol, both in the short term, but hopefully in the long term too.
The origins of Dry January are traced way back to 1942 Finland. The Finns decided to have their own sober January in attempts to make savings during the ongoing war against the Soviet Union. But more recently, the Dry January concept was popularized by Alcohol Change UK, who also trademarked the term.
