1. Dopamine in love: Dopamine is a neurotransmitter primarily responsible for transmitting signals of happiness and excitement. In the early stages of love, the massive release of dopamine can cause a strong sense of pleasure, excitement, and desire to be with the other person, which is an important physiological basis for the "passionate" part of love.
2. Hormones in love: Hormones play complex and critical roles in love, including oxytocin, vasopressin, and testosterone. Oxytocin and vasopressin help enhance intimacy and trust between partners, promoting the formation of emotional bonds. Testosterone and other sex hormones affect an individual's sexual attractiveness and desire for a partner, further deepening the depth of love.
3. Comprehensive effect: Love is not just the simple action of dopamine and hormones, it also includes complex interactions at multiple levels such as emotions, cognition, society, and culture. Dopamine and hormones provide the physiological driving force and emotional experience foundation for love, but true love also needs to be built on mutual understanding, respect, trust, and support. It is one-sided to attribute love solely to dopamine and hormones, as it overlooks the richer and deeper connotations of love.
