4. Conclusions
In the field laboratory experiment, emotion, fatigue survey, and subjective evaluation were used to evaluate the effects of wooden and non-wooden environments on psychological responses. Conclusions can be obtained as follows: 1) Participants had more positive emotions in wooden rooms, especially after working. Clear differences were shown for the sense of “tension,” “depression,” and “vigor” between wooden and non-wooden environments. 2) Working in a non-wooden environment was more likely to produce fatigue. The differences in fatigue in the two kinds of environments were clearly reflected through the symptoms of “sleep,” “yawn,” “see fuzzy,” and “eye fatigue.” 3) The survey method using emotion questionnaire and fatigue self-assessment showed that the wooden environment had the potential to restore the ability to regulate emotion and relieve stress. 4) The subjective feeling was different for the sense of color, warmth, lighting, and odor in wooden and non-wooden environments. Participants feel more warmth and brightness in wooden rooms and have sensitivity to odor, but it has little in- fluence on the comfort degree.
