An online questionnaire was administered to 172 people to clarify the influence of the act of supporting one’s favorites. The data revealed that approximately three-fourths of the respondents felt an improvement in subjective health and self-esteem after beginning to act to support their favorites. In addition, spending time or money on supporting one’s favorite had a great influence on subjective health and self-esteem. Our findings indicate that the act of supporting one’s favorites can enhance one’s well-being.
