摘要

在这项研究中,我们使用芳樟醇(LNL)和反式-2-壬烯醛(T2N)研究了工作间气味环境对自律神经活动(ANS)和精神运动警觉水平(PVLs)的影响。受试者为六名健康男性(31 ± 6 岁)和六名健康女性(24 ± 5 岁)。他们在充满 LNL 和 T2N 气味的工作间内坐了 10 分钟,并测量了他们的心电图(ECG)、皮肤电导水平、脉搏波变异性、皮肤温度和座椅压力分布。此外,还在进入工作间前后进行了正压负荷测试(OLT)和精神运动警觉性测试(PVT),并在实验后对气味进行了主观评价。本文侧重于心电图和 PVT 数据,分析了心率变异性指数和 PVT 分数的变化。男性对 LNL 气味略感不适,并在气味呈现后表现出促进 OLT 交感神经活动。女性对 T2N 气味稍感不适,并在嗅觉呈现后的 OLT 中表现出交感神经活动增强和 PVT 分数下降。在 ANS 和 PVL 方面观察到了性别差异,可能是 LNL 的舒适感增加了男性的交感神经活动,而 T2N 的不舒适感可能降低了女性的工作表现。

An Evaluation of the Autonomic Nervous Activity and Psychomotor Vigilance Level for Smells in the Work Booth
In this study, we investigated the effects of the smell environment in the work booth on autonomic nervous activity (ANS) and psychomotor vigilance levels (PVLs) using linalool (LNL) and trans-2-nonenal (T2N). The subjects were six healthy males (31 ± 6 years old) and six healthy females (24 ± 5 years old). They sat in the work booth filled with the smells of LNL and T2N for 10 min, and their electrocardiograms (ECGs), skin conductance levels, pulse wave variabilities, skin temperatures, and seat pressure distributions were measured. In addition, the orthostatic load test (OLT) and psychomotor vigilance test (PVT) were performed before and after entering the work booth, and a subjective evaluation of the smell was also performed after the experiment. This paper focused on ECG and PVT data and analyzed changes in heart rate variability indices and PVT scores. Males felt slightly comfortable with the LNL smell and showed promoted sympathetic nerve activity in the OLT after the smell presentation. Females felt slightly uncomfortable with the T2N smell and showed promoted sympathetic nerve activity and a decrease in PVT scores in the OLT after the smell presentation. Gender differences were observed in ANS and PVLs, and it is possible that the comfort of LNL increased sympathetic nervous activity in males, while the uncomfortableness of T2N may have reduced work performance in females.
