• 12．Binge-watching（追剧）your favorite TV series is bad for your brain.Dr.Randall Wright，based in Texas，said the need to watch episode（集）after episode has a similar influence on the brain to gambling （赌博）.What's more，it often leads to social loneliness，snacking on junk food and a shortage of exercise and sleep，which，over time，is bad for the brain.
     When you let auto play start the next episode，you can find out what happens next and your brain receives good feedback，Dr.Wright wrote in an article.This right-away satisfaction is similar to gambling where even after a win，you are not satisfied and want to continue playing.With binge-watching，you are not satisfied with stopping after episode five and want to continue watching.This cycle coupled with the snacking and the long time sitting can lead to unhealthy changes in your brain and body over time.
     Dr.Wright said，"Binge-watching itself is not bad.It becomes problematic when you are watching a third，fourth or fifth episode instead of doing healthy activities." But he said it is possible to avoid the bad influence of binge-watching with four tips，including staying away from salty，fatty，calorific foods，exercising before a binge-watching，setting an alarm for sleep and balancing TV viewing with socializing.
     If you add these tips to your binge-watching practice，you can create lasting healthy habits and still enjoy the now-and-then binge-watching time without hurting your brain.
