The emotion and sleep-related problems of humans who are on mission of deep-space and deep-sea exploration are topics of special interest because of the isolated environment. Effective regulatory approaches should be developed to manage the positive emotions and sleep quality in a long-duration isolated environment. The results reported that emotion and sleep were closely linked to each other because plants could significantly regulate humans’ emotion and sleep through their own color and fragrance. Additionally, the light conditions prevailing in that location also had significant influence on humans’ emotion and sleep. There have been few reports on the synergistic effects of plants with light environment on humans’ physical and mental health. In this research, three species of edible plants and three color temperature levels that were commonly used in people's living environment were selected. Then orthogonal tests were conducted in the cabins of “Lunar Palace I” in the middle of the third phase of the “Lunar Palace 365″ experiment, and salivary cortisol levels, emotion, and sleep conditions of the volunteers were measured. The results showed that in the long-duration isolated environment, strawberry had a better effect than purple rape and coriander on improving positive emotion. Exposure to coriander before bedtime might help people to rapidly go to sleep, increase sleep integrity, and sleep efficiency in the isolated environment. Moreover, there appeared to be a positive synergistic effect of edible plants with light environment on micro-awakening index and sleep efficiency. These results provided a scientific basis for improving the physiological and psychological health of people in the long-duration isolated environment by changing the light environment with appropriate plants.

由于环境隔离，承担深空和深海探索任务的人类与情绪和睡眠有关的问题成为特别令人关注的话题。应该开发有效的监管方法，以在长期隔离的环境中管理积极的情绪和睡眠质量。结果报告说，情绪和睡眠彼此紧密相连，因为植物可以通过自身的颜色和香气显着调节人类的情绪和睡眠。此外，该位置盛行的光照条件也对人类的情感和睡眠产生了重大影响。关于光环境下的植物对人类身心健康的协同作用的报道很少。在这项研究中 选择了人们生活环境中常用的三种食用植物和三种色温等级。然后在“ Lunar Palace 365”实验第三阶段的中间，在“ Lunar Palace I”的船舱中进行正交测试，并测量志愿者的唾液皮质醇水平，情绪和睡眠状况。结果表明，在长期隔离的环境下，草莓在改善积极情绪方面比紫色油菜和香菜更好。睡前接触香菜可能会帮助人们迅速入睡，增加睡眠完整性，并在孤立的环境中提高睡眠效率。此外，光环境下的可食植物似乎对微觉醒指数和睡眠效率具有积极的协同作用。
