Ah, the early stages of love—where everything feels like a scene from a rom-com. But guess what? It’s not just all butterflies and sunshine. Nope, there’s some serious chemistry going on behind the scenes.
Dopamine, often referred to as the “pleasure neurotransmitter,” is released in response to novel and rewarding experiences, such as spending time with a new romantic partner. This dopamine surge leads to feelings of euphoria, motivation, and intense pleasure.
Likewise, serotonin levels tend to increase during the initial stages of a relationship. This elevation can make the emotional attachment to the individual who is causing the serotonin levels to rise to be more pronounced.
Additionally, the hormone oxytocin, sometimes called the “love hormone” or “bonding hormone,” is released during intimacy. It’s like your brain’s personal cupid, working its magic during those cozy cuddle sessions, steamy smooches, and other intimate moments. When oxytocin kicks in, it’s like a warm hug for your heart, deepening that emotional bond.
These biochemical actions, on some level, explain the deep sense of attachment and addictive tendencies toward another human. Researchers found in one study that numerous parts of the brain are set ablaze when people are shown a picture of someone they love.
Not surprisingly, most of the brain regions illuminated were related to the neural reward system, which can be the same with addictive substances. Therefore, when a romantic partner is suddenly out of your life, the lack of reward system response can be a little like substance withdrawal.
