Subjective well-being refers to an individual's overall sense of happiness and satisfaction with life. It encompasses both cognitive evaluations of one's life (such as life satisfaction and fulfillment) and affective experiences (such as positive emotions and feelings of contentment). Researchers studying subjective well-being seek to understand the factors that contribute to an individual's well-being, including social relationships, personal values, mental health, and life circumstances. This area of research aims to improve individual and societal well-being by identifying strategies to enhance happiness and life satisfaction.
