Wood has been an important raw material for centuries, and humans encounter it in the form of furniture and building materials or in products of daily use. The odors emanating from such wood-based materials can add another facet to their functionality by influencing human well-being and mood. Moreover, wood odors can be used in odor-enhanced environments to foster relaxation and stress recovery. The current study was conducted to assess the subjective evaluation of, and physiological responses to, wood odors and individual wood odor constituents. The subjects smelled the odors of pine needles oil, cedar wood oil, α -pinene, and thymoquinone and evaluated the odor percept and their subjective feelings. Heart rate, finger temperature, and skin conductance were monitored throughout the experiment. The results showed that wood odors were distinct regarding their pleasantness, familiarity, and intensity. All odors enhanced the subjective feelings of happiness and content. Though no odor-specific physiological effects became evident, certain physiological measures correlated with self-reports of happy and relaxed feelings and the intensity ratings of the odors. The present study provides a basis for further studies on the use of wood odors as ambient scents and helps understanding the influence of natural odors on humans.

走出树林：对木材气味的心理生理学调查，以估计它们作为环境气味的适用性

几个世纪以来，木材一直是一种重要的原材料，人类在家具和建筑材料或日常用品中都会遇到它。此类木质材料散发出的气味会影响人类的幸福感和情绪，从而为其功能增加另一个方面。此外，木材气味可用于气味增强的环境中，以促进放松和压力恢复。目前的研究旨在评估对木材气味和个别木材气味成分的主观评价和生理反应。受试者闻松针油、雪松木油、α-蒎烯和百里醌的气味，并评价气味感知和主观感受。在整个实验过程中监测心率、手指温度和皮肤电导。结果表明，木材气味在愉悦度、熟悉度和强度方面是不同的。所有的气味都增强了主观幸福感和满足感。虽然没有明显的气味特异性生理效应，但某些生理指标与自我报告的快乐和放松的感觉以及气味的强度等级相关。本研究为进一步研究使用木材气味作为环境气味提供了基础，并有助于了解自然气味对人类的影响。
