Love is a complex emotion. It can be as simple as a warm feeling, or it can be as complicated as a relationship between two people. It can also refer to a feeling of loyalty and devotion to a cause or to another person, animal, or idea. It is commonly contrasted with lust and hate, as well as with compassion and agape.
Many scholars, philosophers, and poets have debated about what love really means. Some scientists and psychologists have characterized it as a primary emotion, while others see it more as a basic drive or motivation. Regardless of its definition, love can affect the health of a person’s mind and body. In healthy relationships, it can lead to feelings of trust, care, patience, and respect for a partner. It can also create a strong sense of attachment that is protective and supportive. In unhealthy relationships, love can be toxic and can have a negative impact on one’s mental health.
Scientific research on love has increased over the past few decades. Several theories have been proposed, including the color wheel theory of love, which defines three primary, three secondary and nine tertiary love styles based on intimacy, passion, and commitment. Other researchers have suggested a triangular theory of love that distinguishes between companionate, eros and romantic love.
