室内空气中的化学浓度与人类舒适和放松感之间的关系已有报道。我们在两栋内部和外部外观几乎相同的实验室房屋中研究了挥发性有机化合物总量（ΣVOC；79 种 VOC 的总量）对放松水平的影响。通过监测脑电图（EEG）来客观评价个人的放松程度。实验在 ΣVOC 含量较低和较高的实验室 (LH) A 和 B 中进行。共有 168 名健康志愿者参与，每人执行任务 20 分钟，然后休息 10 分钟，休息期间测量脑电图。在进行主观评估的同时，参与者还被要求填写一份关于每个 LH 的气味强度和空气质量偏好的调查问卷。主观评价显示ΣVOCs与参与者的放松程度之间存在显着相关性（OR：2.86，95%CI：1.24-6.61），客观评价表明ΣVOCs水平较低的参与者在LH中比水平较高的参与者更放松（OR：3.03，95%CI：1.23-7.50）。因此，减少室内空气中的ΣVOCs和异味就会起到促进放松的效果。
The relationship between chemical concentrations in indoor air and the human sense of comfort and relaxation have been reported. We investigated the effect of the sum of volatile organic compounds (ΣVOCs; sum of 79 VOCs) on the level of relaxation in two laboratory houses with almost identical interior and exterior appearances. The electroencephalogram (EEG) was monitored to evaluate the degree of personal relaxation objectively. The experiments were conducted in laboratory houses (LH) A and B with lower and higher levels of ΣVOCs, respectively. A total of 168 healthy volunteers participated, who each performed the task for 20 min, followed by a 10-min break, and EEG was measured during the break. Simultaneously as subjective evaluations, the participants were asked to fill a questionnaire regarding the intensity of odor and preference for the air quality in each LH. The subjective evaluation showed a significant association between ΣVOCs and participants’ relaxation (OR: 2.86, 95%CI: 1.24–6.61), and the objective evaluation indicated that the participants were more relaxed in the LH with lower levels of ΣVOCs than that with higher levels (OR: 3.03, 95%CI: 1.23–7.50). Therefore, the reduction of ΣVOCs and odors in indoor air would have an effect, which is the promotion of relaxation.
