Throughout the history of humanity, the question of what constitutes a good life has been a significant topic. Various philosophers have attributed different meanings to the concepts of well-being and happiness. Some associate a good life with a list of virtues, while others emphasize the importance of pleasurable feelings. Positive psychology emerged as an approach that emphasizes well-being and acknowledges happiness as a fundamental goal. The concept of well-being is defined in various ways to describe a positive state experienced by individuals and societies. Well-being encompasses both hedonic and eudaimonic approaches. Positive psychology utilizes scientific methods to understand well-being and examine the nature of happiness. According to the World Happiness Report, Turkey's low ranking in the international evaluation of happiness levels indicates a need for improvement in well-being areas. Globally, identifying the factors that can enhance happiness and quality of life, especially in countries that rank lower, is crucial for societies. Public policies and strategies need to focus on promoting happiness and well-being to enhance the welfare level of society. There is growing evidence that physical activity increases happiness levels and improves quality of life. Therefore, physical activity promotion may be an effective strategy for increasing happiness levels and has important potential for supporting societal well-being.
