摘要：An overview of the research conducted as of this writing has been used to clarify the positive effects of physical activity on mood swings, as well as its application in alleviating symptoms of depression. The influence and role of individual chemical messengers have also been explained in these studies. Years of extensive research have suggested that the excretion of these messengers is enhanced by physical activity, which helps them to enhance moods. This paper places special emphasis on the role of endorphins and the effect of their excretion during physical activity on mood swings and on the development of exercise addiction. A short review also addresses the possible negative influence of physical activity, and a conclusion sets forth the categorization of various physical activities based on their potential ability to induce a desired positive influence on mental health.
