Description
Summary:Aromatic plants hold great potential to affect the health of urban residents. Studying the positive effects of natural aromas emitted by aromatic plants on urban residents is necessary. In this research, Pink Jasmine (Jasminum polyanthum), a woody vine species widely used in urban landscape, was selected as the research subject to address the following research questions: Whether the natural aromas from Pink Jasmin’s flowers can influence human health? How do the period of exposure to the aroma affect its effects? A total of 48 college students were recruited to participate in a controlled study. The participants were divided into three groups, and olfactory experiments were conducted in the morning, afternoon, and evening. Their emotional and mood states were measured using an EPOC+ portable EEG headset and the POMS scale. The results showed that smelling the Pink Jasmin’s flowers can promote positive emotions and relaxation in three periods. Among them, exposure in the morning can enhance vigor, exposure in the afternoon can alleviate negative emotions, and exposure in evening may lead to better relaxation and alleviate depression; Our results provide support for the incorporation of Pink Jasmin, as well as aromatic woody vine species in a broader sense, in urban green spaces with the objective of enhancing their health benefits. •Smelling Pink Jasmine has physiological and psychological restorative effect.•Smelling Pink Jasmine can make people feel relaxed and alleviate negative emotions.•Smelling was shown to promote positive emotions and relaxation in three periods.
