Exposure to a natural environment has been reported to be associated with positive effects on mental well-being. However, no report has examined the effects of a house designed with an open space connected to nature on recovery from fatigue.
The purpose of this study was to examine the effects of such an open space on recovery from mental fatigue.
Placebo-controlled, crossover design.
Participants were randomized into open (connected to nature) and closed (not connected to nature) conditions.
Sixteen healthy female volunteers were enrolled.
After a 30-minute fatigue-inducing mental task, participants moved to an open or closed recovery room for 30 minutes.
As fatigue-evaluating mental tasks, participants performed advanced trail making tests for 20 minutes. They were asked to rate their levels of fatigue, relaxation, comfort, and healing on a visual analogue scale from 0 (minimum) to 100 (maximum) to evaluate their subjective mental. They also underwent accelerated plethysmography.
After the recovery session, lower total error counts of a cognitive test, greater levels of subjective relaxation, comfort, and healing, and lower levels of waveform index-1 assessed via accelerated plethysmography were observed in participants exposed to the open condition compared with the closed condition. These results provide evidence that the use of a house designed with an open space connected to nature during the recovery session improved cognitive function and subjective mental states. Hence, open space was effective for helping recovery from mental fatigue.
接触自然环境被报道与心理健康的积极影响有关。然而，目前还没有报告检查过与自然相连的开放式空间设计的房屋对疲劳恢复的影响。
本研究旨在检验这种开放式空间对精神疲劳恢复的影响。
安慰剂对照、交叉设计。
将参与者随机分为开放式（与自然相连）和封闭式（与自然不相连）条件。
16 名健康女性志愿者被纳入研究。
在进行 30 分钟的疲劳诱发心理任务后，参与者转移到开放式或封闭式恢复室 30 分钟。
作为疲劳评估的心理任务，参与者进行了 20 分钟的高级追踪测试。他们被要求在 0（最低）到 100（最高）的视觉模拟量表上对他们的疲劳、放松、舒适和恢复程度进行评分，以评估他们的主观精神状态。他们还接受了加速体积描记法检查。
与封闭式条件相比，在开放式条件下，参与者在认知测试中的总错误计数更低，主观放松、舒适和恢复程度更高，加速体积描记法评估的波形指数-1 水平更低。这些结果表明，在恢复期间使用与自然相连的开放式空间设计的房屋可以改善认知功能和主观精神状态。因此，开放式空间有助于缓解精神疲劳。
