Nature experiences have been linked to mental and physical health. Despite the importance of understanding what determines individual variation in nature experience, the role of genes has been overlooked. Here, using a twin design (TwinsUK, number of individuals = 2,306), we investigate the genetic and environmental contributions to a person's nature orientation, opportunity (living in less urbanized areas), and different dimensions of nature experience (frequency and duration of public nature space visits and frequency and duration of garden visits). We estimate moderate heritability of nature orientation (46%) and nature experiences (48% for frequency of public nature space visits, 34% for frequency of garden visits, and 38% for duration of garden visits) and show their genetic components partially overlap. We also find that the environmental influences on nature experiences are moderated by the level of urbanization of the home district. Our study demonstrates genetic contributions to individuals' nature experiences, opening a new dimension for the study of human-nature interactions.
自然体验与身心健康有关。尽管了解是什么决定了个体在自然体验上的差异很重要,但基因的作用却被忽视了。在这里,我们使用双胞胎设计(TwinsUK,个体数量=2306),研究了个体的自然取向、机会(生活在城市化程度较低的地区)以及不同维度的自然体验(公共自然空间访问的频率和持续时间以及花园访问的频率和持续时间)的遗传和环境贡献。我们估计自然取向(46%)和自然体验(公共自然空间访问频率为 48%,花园访问频率为 34%,花园访问持续时间为 38%)具有中等的遗传度,并表明它们的遗传成分部分重叠。我们还发现,家庭所在地区的城市化水平调节了对自然体验的环境影响。我们的研究表明,个体的自然体验受到遗传因素的影响,为人类与自然相互作用的研究开辟了一个新的维度。
