The fresh start effect

People have been doing New Years Resolutions forever. You’re more likely to run a marathon at a milestone age like 30, 35 or 40. A study in 2014 dubbed it the “fresh start effect” and found that people were more likely to search for terms like “diet” and “gym” at the start of a new year, and that they were more likely to actually go to the gym in the first week of a new year.1
