It takes 66 days to form a habit

It takes 66 days to form a habit

It takes 66 days for a healthy resolution to become an ingrained habit, researchers have claimed.

That was the average time it took for volunteers in a study to begin doing automatically something they had adopted as a daily duty, such as eating fruit with their lunch or going for a run before dinner.
It means if you make a New Year's resolution to exercise or eat healthily and do it daily until March 7, it is likely to stick.

The research, the first to investigate how long it takes to form a habit, has significant implications for people who want to adopt a healthy lifestyle or stick to a diet.
The same team has now been funded by the Medical Research Council for more research looking at how to use habit creation in weight loss.
"What we found was that it takes 66 days on average for people in our study to acquire a habit," says Professor Jane Wardle, of University College London, who carried out the study with Dr Phillippa Lally.
"It varied between individuals, but the finding is that if you do something everyday in the same situation, it will become an automatic reaction in response to those situational cues, a habit. It is the first time this has been established."
"Performing an action for the first time requires planning, even if plans are formed only moments before the action is performed, and attention.
"As behaviours are repeated in consistent settings they then begin to proceed more efficiently and with less thought as control of the behaviour transfers to cues in the environment that activate an automatic response - a habit."
In the research, being reported in the European Journal of Social Psychology, the researchers set out to investigate how long it took for the repetition of behaviour to reach a stage of 'automacity', where it is performed whenever the situation is encountered without thinking, awareness or intention.
The volunteers who took part in the study were asked to choose a healthy eating, drinking or exercise behaviour that they would like to make into a habit.
It had to be done in response to a particular cue, such as eating a piece of fruit with lunch, drinking a bottle of water with lunch, or running for 15 minutes before dinner. Participants were asked to try to carry out the behaviour every day.
Each day they also completed a test designed to measure features of habits which are central to automaticity, including lack of awareness and lack of control.
Results showed that whilst the average time to form a habit was 66 days, more complex behaviours took longer, whilst an exercise habit took longer to form than a healthy eating or drinking habit.

習慣66天養成

英國研究人員說,養成一個習慣,要六十六天。
倫敦大學的心理教授沃迪說,不論是要早起運動,節食減肥只要能撐過六十六天多半就成功了。他說,養成一個習慣,需要的時間因人而異,但是平均是六十六天。
沃迪說,要做一件事以前,大家都會計劃。接著就是實行。實行過六十六天,這件事就成了日常生活的一部份,到時候就會做,也就成了習慣了。
在他的實驗裡,他請受試的人選擇午餐時候吃水果,或是喝一瓶水。同時要求他們每天都得做。他每天會給受試的人一個測驗,看他們什麼時候開始不自覺的吃水果、喝水。結果發現,大約到第六十六天,多數人到午餐的時候都會不自覺的吃起水果或是拿起水瓶。
不過,比較需要毅力的習慣,譬如,每天跑步十五分鐘,養成的時間會長一點。
