The science of happiness and well-being explores factors that contribute to a fulfilling and positive life. Research shows that happiness is influenced by genetics, life circumstances, and intentional activities like gratitude, mindfulness, and social connections. **Positive psychology** emphasizes the importance of strengths, optimism, and resilience in enhancing well-being. Regular exercise, healthy relationships, and engaging in meaningful work also boost happiness. The brain releases chemicals like **dopamine** and **serotonin** during positive experiences, contributing to feelings of joy. Long-term well-being is fostered by achieving a balance between physical health, mental resilience, and emotional satisfaction.
