草莓园艺对室内久处人群自主神经反应与情绪的影响

Effect of Strawberry Gardening on Autonomic Nervous Response and Emotion of People Long-term Staying Indoor

目的研究室内可食植物园艺对室内久处人群的情绪和生理的改善效果,为可食植物园艺在室内环境和空间站等特殊环境中的应用提供新的证据。方法24名久处室内的在校大学生作为受试者,分为草莓园艺组和对照组,每组12人。草莓园艺组要求受试者进行15min的草莓园艺,对照组不提供草莓植株,只做修剪动作。检测两组受试者实验前后心率、血压、皮肤温度的变化,利用POMS主观情绪量表进行评分,并检测受试者唾液皮质醇含量,分析草莓园艺对室内久处人群自主神经反应与情绪调节的影响及其相关性。结果草莓园艺可以显著降低受试者心率和舒张压(P<0.05)。同时,草莓园艺后,受试者唾液皮质醇含量下降,疲劳、抑郁和慌乱等负向情绪得分显著降低(P<0.05),相反的正向情绪精力和自尊心得到显著提升(P<0.05)。相关性分析发现,心率与疲劳和慌乱情绪呈显著正相关。结论草莓园艺可以改善室内久处人群的情绪,影响人体自主神经反应,且此调节过程中人员情绪变化与自主神经反应存在一定的相关性。

Objective The effects of strawberry gardening on autonomic nervous responses and emotion of subjects long-term staying indoors were studied in this research to provide new evidence for the application of edible plant gardening in indoor environment and space stations.Methods Twenty-four college students long-term staying indoors were divided into strawberry gardening group and control group(n=12).The subjects in the strawberry gardening group were required to perform strawberry gardening for 15 min,while the control group did not provide strawberry plants.The changes of the heart rate,blood pressure and skin temperature of subjects in the two groups were detected to assess the activity of the autonomic nervous system.Subjective emotions were evaluated using the POMS scale.The salivary cortisol content was detected.The influence of strawberry gardening on the autonomic nervous response and emotions of subjects long-term staying indoors and their correlation were analyzed.Results The results showed that strawberry gardening could reduce the autonomic parameters significantly including the heart rate and the diastolic blood pressure(P<0.05).At the same time,the cortisol levels and the negative emotion levels such as fatigue,dejection,and confusion were also reduced significantly,and positive emotions such as vigor and self-esteem were improved obviously after strawberry gardening(P<0.05).In addition,the heart rate was positive correlated to fatigue and confusion.Conclusion The findings suggested that emotion and autonomic nervous responses of human who stay indoors for a long time would be effected by strawberry gardening,and there is a correlation between emotional changes and autonomic nervous responses.
