A healthy standard of living – characterised by access to nutritious food, safe housing, clean environments, education, and healthcare – is essential for overall well-being because it supports physical health, mental stability, and social participation. When people lack these basic conditions, they are more likely to experience chronic illness, stress, and reduced life expectancy, which deepens health inequalities. Addressing these disparities requires systemic changes that ensure everyone, regardless of background or income, can live in conditions that promote good health.
