People should be encouraged to spend time in parks and gardens, researchers say.

研究人员建议，应该鼓励人们花点时间在公园和花园里。

- LONDON — Just five minutes of exercise a day in the great outdoors can improve mental health, according to a study released on Saturday, and policymakers should encourage more people to spend time in parks and gardens.

-伦敦-根据在周六发布的一篇研究结果，每天只要在室外5分钟就可以提高心理健康状况。决策者应该多多鼓励人们在公园里度过时光。

Researchers from the University of Essex found that as little as five minutes of a "green activity" such as walking, gardening, cycling or farming can boost mood and self esteem.

埃塞克斯大学的学者发现，5分钟的“绿色活动”可以促进情绪和自尊。这些活动包括，散步，种花，骑自行车或是耕作。

"We believe that there would be a large potential benefit to individuals, society and to the costs of the health service if all groups of people were to self-medicate more with green exercise," Barton said in a statement about the study, which was published in the journal Environmental Science & Technology.

“我们相信，如果所有人都用绿色锻炼的方式自我医疗的话，将对个人，社会和卫生服务业的花费都有巨大的潜在利益。”Barton在已发表在环境科学与技术周刊上的研究声明里说到。

Many studies have shown that outdoor exercise can reduce the risk of mental illness and improve a sense of well-being, but Jules Pretty and Jo Barton, who led this study, said that until now no one knew how much time needed to be spent on green exercise for the benefits to show.

很多研究都显示室外运动可以减低心理疾病的风险，并且能增加幸福感，但是进行这项研究的Jules Pretty 和Jo Barton说至今还没有谁知道要在绿色运动中花多少时间才能让效果显现。

Barton and Pretty looked at data from 1,252 people of different ages, genders and mental health status taken from 10 existing studies in Britain.

Barton 和 Pretty在英国正进行的10个研究中查看了来自不同年龄、性别和心理健康状况的1252人的数据。

They analyzed activities such as walking, gardening, cycling, fishing, boating, horse-riding and farming.

他们分析了像漫步、种花、骑自行车、钓鱼、划船、骑马和耕作之类的运动。

They found that the greatest health changes occurred in the young and the mentally ill, although people of all ages and social groups benefited. The largest positive effect on self-esteem came from a five-minute dose of "green exercise."

他们发现，虽然所有年龄和社会团体都从中受益，但绿色运动在年轻人和心理健康不良的人中造成的改变最大。对自尊产生最积极影响的“绿色运动量”是5分钟。

All natural environments were beneficial, including parks in towns or cities, they said, but green areas with water appeared to have a more positive effect.

他们说，包括城市和乡村的公园等等，所有的自然环境都是有利的。而且，绿色的环境里如果还有水存在的话，会带来更积极的影响。
