“与上周没有接触自然相比，一周接触自然时间大于等于120分钟时，报告健康良好或者幸福感高的可能性显著上升了。”作者总结说。

The findings are supported by past research, which has found that living in greener areas is associated with lower risks of cardiovascular disease, obesity, diabetes, asthma emergencies, mental distress, mortality and even myopia in children. Some have even landed on this 120 minute threshold before.

过去的研究支持了这项发现。之前的研究发现，对孩子来说，在绿色区域生活患心血管疾病、肥胖、糖尿病、紧急哮喘、精神沮丧、死亡甚至近视的风险更低。有些孩子甚至之前就达到了120分钟的临界值。

Nevertheless, these results are still in their infancy, and it remains unclear how much exposure we humans truly need to reap the benefits.

尽管如此，这些结果还在初期，仍然不清楚我们人类需要与自然接触多久才能获益。

Exploring this idea further, participants in the most recent study were asked how much nature they had experienced in the last seven days.

进一步探索这个想法，问最新研究的参与者最近七天在自然中的经历有多少。

Randomly selecting just one of these "nature diary entries", the interviewer then asked for more details, including how long the visit was, who they went with, how they got there, and what they got up to.
