Social health refers to an individual's ability to interact with others and form relationships, as well as the health of society in terms of how people interact and treat one another. It is one of the three fundamental forms of health, along with physical and mental health. Social health deals with how well a person can socialize, make and keep friends, and have positive relationships. Strong social ties are important for both individual and societal well-being, as isolation can negatively impact physical and mental health, and conflict within a society is a sign of poor social health. Developing social skills over one's lifetime through experiences helps to promote good social health.
