Episode notes
Limerence As An Altered State
- Limerence is an altered cognitive state of obsessive infatuation focused on reciprocation and pair-bonding.
- About half of people experience limerence as the intense early phase of romantic love, producing euphoria and intrusive thoughts.
Three-Brain Systems Behind Limerence
- Limerence combines arousal, reward (dopamine-driven wanting), and bonding (oxytocin/vasopressin) systems.
- When reward and bonding imprint on one person strongly, that person can become an addictive natural reward.
Channel Limerence Toward Healthy Bonds
- View limerence as potentially useful when it leads to healthy bonding, not only pathology.
- Seek connections with reciprocal, healthy partners to convert limerence energy into stable relationships.
