Habits are easy to form. Just look at everything you do every day on “auto pilot.” Some of our habits are good, healthy ones – others, not so much.
Habits can be formed by sheer repetition of actions. They can also be formed when the brain’s reward center is triggered by the release of dopamine. Actions or events we find enjoyable – including activities like smoking, overeating, gambling and even compulsive use of computers and social media – trigger dopamine release.
Both types of habits can become hard-wired in the brain. That makes them automatic, so we don’t have to consciously think about them.
