A new study challenges the belief that it takes just 21 days to form a new habit, revealing that it can actually take anywhere from two months to nearly a year for healthy habits to take root. The research found that while habits can start forming within about two months, the time required varies among individuals, ranging from four days to 335 days. The study analyzed the time it takes for new habits to become automatic behaviors and found that the time required to form healthy habits varies greatly by individual and depends on the type of habit in question. The findings emphasize the importance of perseverance in habit formation and suggest incorporating new habits into a regular morning routine may help in forming them.
