Exposure to green space and nature has a potential role to play in the care of people with dementia, with possible benefits including improved mood and slower disease progression. In this observational study at a dementia care facility in the UK, we used carer-assessed measures to evaluate change in mood of residents with mid- to late-stage dementia following exposure to a nature garden. We found that exposure to nature was associated with a beneficial change in patient mood. There was a non-linear relationship between time spent outdoors and mood outcome. Improvements in patient mood were associated with relatively short duration exposures to nature, and no additional measureable increases in mood were found with exposures beyond 80-90 minutes duration. Whilst further investigation is required before causality can be determined, these results raise important questions for policy about the integration of outdoor space into the design of dementia care facilities and programmes.
接触绿色空间和自然环境在痴呆症患者护理中可能发挥作用，潜在益处包括改善情绪和减缓疾病进展。在英国一家痴呆症护理机构进行的这项观察性研究中，我们采用护理人员评估的方法，来评估中晚期痴呆症患者接触自然花园后情绪的变化。我们发现，接触自然与患者情绪的有益变化相关。在户外停留的时间与情绪结果之间存在非线性关系。患者情绪的改善与相对较短时间接触自然有关，接触时间超过80 - 90分钟后，情绪没有可测量的额外提升。虽然在确定因果关系之前还需要进一步研究，但这些结果给政策提出了重要问题，即如何将户外空间融入痴呆症护理设施和项目的设计中。
