If you'd like to cut down your alcohol consumption or start the new year with a clean slate, join in the Dry January challenge by choosing not to drink beer, wine, or spirits for one month. Dry January began in 2012 as a public health initiative from Alcohol Change UK, a British charity. Now millions take part in this health challenge every year.

Dry January is an annual health initiative in which people abstain from drinking alcohol—beer, wine, and spirits—for one month. Partaking in the challenge can offer health benefits, even for casual drinkers, such as improved sleep, increased energy, weight loss, and lower blood pressure.

Dry January, the month-long no-alcohol challenge, offers a reset and a chance to try healthier habits after weeks of overindulging in holiday drinking. That means no beer, wine or spirits, but exploring the growing menu of mocktails, sparkling water and other non-alcoholic drinks.

The popular health trend challenges participants to forego alcohol for 31 days in a row. Americans across the nation have been tacking on the alcohol abstinence challenge to their New Year's resolutions for years and sharing their experiences with the challenge on social media. And doctors have tips for completing the challenge without faltering.

Taking the challenge of going dry in January, or Dry January, i.e. having no alcohol for the entire month, is one resolution that might actually make you healthier. The Dry January campaign was started in 2013 by Alcohol Change U.K., a charity focused on reducing alcohol harm.
