Yes, it is true that participating in sports can greatly increase mental well being.
As reported by Advent Health, getting involved in sports (whether they call for solo or team participation) can improve mental health in subtle ways. Their article states that physical activity releases endorphins in the brain that relax and boost our mood. Endorphins fight negativity that may flood our minds, so the act of playing in a sport can leave us feeling encouraged to tackle daily life and its struggles. This boost of mood can also emerge from social interaction if one chooses to participate in a team sport. Furthermore, playing a sport sharpens the mind as experience builds overtime; this growth of skill can improve self confidence and our self image.
Circling back to the original article that this claim was made on, an article written by students, sport participation can, “[reduce] levels of depression, anxiety, and stress.” To make these claims, “Data was extracted for demographics, methodology, and study outcomes, and results presented according to study design,” making the claims presented in this article credible and factual.
Overall, sports can ultimately benefit the mental health of those who participate. All evidence presented within the sources I cited demonstrate the fact that sports can surely help us become happy individuals!
