Good health and well-being are essential for the sustainable development of communities. It is the need of the hour because healthy people are the foundation for healthy economies and peaceful societies. The United Nations Sustainable Development Goal 3, “Good health and well-being” aims to ensure health and well-being for everyone at all stages of life. In the Indian Constitution, Article 47 states: that the state is responsible for improving public health, enhancing the standard of living, and raising the level of nutrition. This includes prohibiting the consumption of drugs and intoxicating drinks that are harmful to health. Sustainable communities prioritize the health and well-being of their residents, recognizing the interdependent relationship between human and environmental health. The purpose of the study is to recognize the relationship between good health & well-being and sustainable communities’ development and also to know the importance of good health required for community development. The data for the study is collected through secondary sources such as journals, books, websites, newspapers, etc. On analyzing the data, the study concludes that there is a strong relationship between good health & well-being and sustainable communities. This can be ensured by improving physical and mental health, strengthening social connections, reducing healthcare costs, proper care of the environment, ease of accessing healthcare services, healthy food options, clean air, land, and water. This safeguards healthy lives and improves the quality of life for all at all ages which is important to building a prosperous society.
