Elderly patients living in long-term care facilities have been restricted from leaving to comply with social distancing guidelines during the COVID-19 pandemic. This has led to a worsening of disorders, such as anxiety and depression. This study aims to understand the health benefits of an immersive garden experience to elderly nursing home residents with mild-to-moderate cognitive impairments. Virtual reality devices were used to provide immersive garden experiences for the residents who were unable to go outside. The heart rate and heart rate variability (HRV) data of the participants of the participants were collected using biofeedback instruments, and changes in the low frequency/high frequency (LF/HF) and the standard deviation of the NN interval (SDNN) values caused by immersive garden experiences were discussed. The results show that the immersive garden experiences were beneficial to these elderly residents. Within 6 min of completing the experiment, we found that the heart rates of participants had dropped slightly, while SDNN and HF values continued to rise. SDNN values before and after the experiment demonstrated a statistically significant improvement. Furthermore, participants expressed their satisfaction with the video intervention program. The results indicated that nursing homes can provide immersive landscape experiences to help increase HRV and SDNN of their elderly residents. This will not only help these residents recall beautiful memories of their past, but will also improve their quality of life.

在 COVID-19 大流行期间，居住在长期护理机构中的老年患者被限制离开以遵守社会疏离准则。这导致了焦虑和抑郁等疾病的恶化。本研究旨在了解沉浸式花园体验对患有轻度至中度认知障碍的老年疗养院居民的健康益处。虚拟现实设备被用来为无法出门的居民提供身临其境的花园体验。使用生物反馈仪器收集参与者的心率和心率变异性（HRV）数据，低频/高频（LF/HF）和NN间隔（SDNN）值的标准偏差（SDNN）值的变化通过沉浸式花园体验进行了讨论。结果表明，沉浸式花园体验对这些老年居民有益。在完成实验的 6 分钟内，我们发现参与者的心率略有下降，而 SDNN 和 HF 值继续上升。实验前后的 SDNN 值显示出统计学上的显着改善。此外，参与者对视频干预计划表示满意。结果表明，养老院可以提供身临其境的景观体验，以帮助提高老年居民的 HRV 和 SDNN。这不仅可以帮助这些居民回忆起他们过去的美好回忆，还可以提高他们的生活质量。我们发现参与者的心率略有下降，而 SDNN 和 HF 值继续上升。实验前后的 SDNN 值显示出统计学上的显着改善。此外，参与者对视频干预计划表示满意。结果表明，养老院可以提供身临其境的景观体验，以帮助提高老年居民的 HRV 和 SDNN。这不仅可以帮助这些居民回忆起他们过去的美好回忆，还可以提高他们的生活质量。我们发现参与者的心率略有下降，而 SDNN 和 HF 值继续上升。实验前后的 SDNN 值显示出统计学上的显着改善。此外，参与者对视频干预计划表示满意。结果表明，养老院可以提供身临其境的景观体验，以帮助提高老年居民的 HRV 和 SDNN。这不仅可以帮助这些居民回忆起他们过去的美好回忆，还可以提高他们的生活质量。结果表明，养老院可以提供身临其境的景观体验，以帮助提高老年居民的 HRV 和 SDNN。这不仅可以帮助这些居民回忆起他们过去的美好回忆，还可以提高他们的生活质量。结果表明，养老院可以提供身临其境的景观体验，以帮助提高老年居民的 HRV 和 SDNN。这不仅可以帮助这些居民回忆起他们过去的美好回忆，还可以提高他们的生活质量。
