The first month of the year is a time for new goals and beginnings. For many, that includes resetting their relationship with alcohol. You or someone you know may be participating in Dry January, a month-long effort to be sober.

The health trend has been popular in many countries for at least a decade, but its roots extend as far back as 1942, when the Finnish government created a campaign called “Sober January” as a propaganda blitz to raise readiness during World War II.

Dr. Christopher Wall, a psychiatrist who is chief medical officer at Prairie Care, joins MPR News host Nina Moini to talk about the health benefits of Dry January.
