Scientific Validation of Sustained Well-being Improvement Through Plogging: Increases in All 34 Metrics

Plogging Japan (Headquarters: Shibuya, Tokyo; Representative Director: Eiichiro Tsuneda), in collaboration with Hapi-Tech Co., Ltd. and the Well-being Research Center of Well-being Design, has scientifically validated the impact of plogging (an activity combining jogging, litter picking, and social interaction) on participant well-being.

This study measured changes in well-being over approximately two months (with a 60-day interval between pre- and post-diagnostics). Analysis using the well-being diagnostic tool 'Well-Being Circle' revealed score improvements in all 34 measured items, with statistically significant differences (p < 0.05) in 13 of them. Significant improvements were observed in areas including trust in the community, stress levels, sense of achievement, communication skills, conscientiousness, ability to enjoy life, and optimism.

Furthermore, the study suggests a 'Surume Effect'—a phenomenon where happiness scores continue to rise with increased experience. Hierarchical changes were also observed: initial participation focused on lower stress, while continued participation fostered social capital such as 'trust in the community.'

The analysis suggests that plogging's effectiveness stems from being an integrated approach of 'physical activity' and 'psychological intervention.' Additionally, the cycle of praise for altruistic acts and unexpected social encounters helps prevent the monotony often associated with solo exercise.
