If you’re a city-dweller feeling a bit blue, you may want to consider going somewhere that’s more green—even if it’s still in a city. Because moving to greener urban areas provides both immediate and sustained mental health benefits. So says a study in the journalEnvironmental Science & Technology.

如果你是一个感觉有点忧郁的城市居民，你可能想考虑去一个更多绿色的地方——即使它仍然在城市里。因为搬到更绿色的城市地区对心理健康有直接和持续的好处。《环境科学与技术》杂志上的一项研究如是说。

The effort is one of the few to look at the effects of green spaces over an extended period of time. Researchers analyzed data from the British Household Panel Survey over a five-year period, splitting participants into two groups: those who moved to greener urban areas and those who moved to less green urban areas.

这项研究是为数不多的在一段较长时间内观察绿化影响的研究之一。研究人员分析了英国家庭小组调查五年来的数据，将参与者分为两组:一组是搬到绿化较好的城市地区的人，另一组是搬到绿化较差的城市地区的人。

In the year after people moved to greener spaces, they experienced a significant boost in mental health markers, such as mood and confidence. And the benefits persisted for the next two years, indicating a shift in their baseline mental health. People who wound up moving to less green areas experienced a temporary, but significant decrease in mental health.

在人们搬到绿化更好的空间后的一年里，他们在情绪和信心等心理健康指标上都有了显著的提升。在接下来的两年里，这种好处持续存在，这表明他们的基本心理健康状况发生了变化。那些最终搬到绿化较少的地区的人，在心理健康方面经历了暂时但显著的下降。

The researchers say these findings should inspire urban planners and policy makers. Because it’s uneasy being not green.

研究人员表示，这些发现应该会激励城市规划者和政策制定者。因为没有绿色会令人不安。
