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...
