Habit formation is the process by which new behaviors become automatic. Someone who instinctively reaches for a cigarette after waking up has a habit. But so does the person who feels inclined to lace up her running shoes and hit the streets as soon as she gets home.
Old habits can be difficult to break, and healthy habits are often harder to develop than one would like. That's because the behavioral patterns we repeat most often are etched into our neural pathways. The good news is that, through repetition, it's possible to form—and maintain—new habits. And even long-time habits that are detrimental to one’s health and well-being can be shaken with enough determination and a smart approach.
