During Dry January the idea is not to drink for the entire month of January. For many people, it is a big step to completely stop drinking alcohol, Planken notes. He has a lot of experience in campaigning on this theme, such as with the campaign ‘Drinking destroys more than you would like’. He has learned a lot about what works and, above all, what doesn’t: “If you say: alcohol is bad for you, it will be counterproductive. You have to approach it in a more positive way, like: try it for a month. Then people will notice. the positive effect of quitting drinking will naturally occur.”
