Objective To explore the effects of water-sand-wind natural resources on the depression of grade 6 students in the third stage of primary school, and to provide a scientific basis and corresponding suggestions for home-school-community collaboration to promote the mental health of primary school students. Experiment A total of 169 students in four classes of sixth grade were selected from a primary school in Xinfeng City, Jiangxi Province by cluster sampling, and one class was a group, namely the control group, the sand group, the water soaking group and the blowing group, and the self-rated questionnaire survey was conducted using the depression self-rating scale (SDS), and the analysis of variance and t-test were used to compare the effects of different natural resources on the depressive mood of primary school students. Results (1) Compared with the control group, the effect of playing with sand was not significant, and blowing wind and soaking in water had a marginally significant effect on the depression of sixth grade students. Among them, blowing wind had a relieving effect on the depression of the sixth grade students, while soaking in water had an aggravating effect on the depression of the sixth grade students. (2) Compared with the sand group, blowing wind had a better alleviating effect on students’ depression. (3) Compared with the soaking group, blowing had a better alleviating effect on students’ depression. Conclusion Blowing the wind on the open sea or grassland or stepping on the forest trail may be an effective strategy to alleviate the depression of primary school students, and provide theoretical guidance for parent-child tourism.
