Large cities are complex urban spaces in which hundreds of thousands of people live and build their socio-economic relations. Megacities are always in the spotlight, because they have a significant impact on the dynamics of social well-being throughout the country. In recent decades, medium and large cities in developing countries have experienced rapid population growth. The researchers note that the governance of cities in this case turned out to be associated with a chaotic scenario, especially in terms of public health management. Health opportunities play a crucial role in shaping social mood. It is widely accepted that good health is the fundamental aspect of human wellbeing, and access to healthcare services is a critical determinant of health status. Recent studies show that if individuals have access to quality healthcare services and are healthier, then they are more productive, engaged, and optimistic. This, in turn, can create a positive mood in society, leading to greater social harmony, economic prosperity, and a better quality of life. The study described in this chapter analyzes the existence of patterns between the level of aggressiveness or positivity of discourse in district online communities and the availability of medical care and accessible sports facilities in those districts.
