Love arose in the course of evolution for a reason. People need to initiate and maintain relationships. Family, friends, kids etc. There may be relationships with And the relationship itself is needed to survive and continue the race.
Love and attraction are based on four neurochemicals. These are dopamine, oxytocin, serotonin, beta-endorphin.
Oxytocin reduces fear and removes barriers to starting a new relationship. In this way, you feel confident when approaching a new acquaintance. Thanks to dopamine released simultaneously with oxytocin, you remember facts about a new acquaintance.
These chemicals interact mainly in the limbic region of the brain, that is, in its unconscious core. This is explained by the fact that attraction is initially a purely instinctive and unconscious feeling.
Beta-endorphin is the long-lasting love hormone. It helps maintain friendly relations between people and is also addictive. Therefore, the person becomes dependent on the object of his love as if he were connected to a higher source.
