本研究旨在建立客观方法来评估含有天然香味的洗护产品对儿童情绪放松的影响。综合脑电图、心电、呼吸信号、血压和面部表情分析技术建立了多维度情绪测量方法，共纳入 26名 9-12 岁儿童进行测试。结果显示使用产品后 5min，α/β 功率比值增加，心率降低；使用产品后 10min，α/β 功率比值依然增加，心率、呼吸频率和脉压均降低，表明实验香型系列产品有助于儿童情绪放松。研究表明该方法适用于评估香味化妆品对儿童的情绪放松效果，且脑电图和心率可作为主要情绪变化的生理参数。该方法可弥补儿童情绪评价能力的局限，为未来研究化妆品对儿童情绪的影响提供辅助。

Although previous studies have reported the effects of scented cosmetic products on adult emotions, research regarding their influence on children's emotions remains limited. This study aimed to establish an objective method for evaluating the effects of naturally scented cleansing and skincare products on emotional relaxation in children. A multidimensional emotion assessment method was established by integrating electroencephalography (EEG), electrocardiography (ECG), respiratory signals, blood pressure, and facial expression analysis technologies. A total of 26 children aged 9–12 years were enrolled in the study for testing. The results demonstrated that 5 minutes after product application, the α/β power ratio increased significantly, whereas heart rate decreased significantly. At 10 minutes after product application, the α/β power ratio increased significantly, while heart rate, respiratory rate, and pulse pressure all decreased significantly. The experimental results indicated that the experimental fragrance product series contributed to emotional relaxation in children. The study demonstrated that this method is suitable for evaluating the emotional relaxation effects of fragranced cosmetic products in children, and that electroencephalography and heart rate may serve as sensitive physiological parameters. This non-invasive and portable method is suitable for children and may compensate for the limitations of children’s self-assessment ability, thereby providing support for future studies on the effects of cosmetic products on children’s emotions.
