Jealousy and the Brain: 5 Ways the Love Hormone Also Feels Like Anger

This article examines the neurobiological relationship between oxytocin (the love hormone) and jealousy, including its anger, fear, and obsessive-compulsive dimensions. Oxytocin's fundamental function is strengthening social bonds and protecting them from threat — producing warmth when bonds are secure and jealousy when they are threatened. The article documents this through: the approach-withdrawal motivation framework (both love and jealousy are approach-motivated states that oxytocin facilitates); fMRI studies showing romantic jealousy activates anger circuits (insula, anterior cingulate cortex, fronto-striatal dopaminergic networks) rather than love circuits; De Dreu's University of Amsterdam research on oxytocin's simultaneous in-group love and out-group hostility; the neurochemical overlap between pathological jealousy and OCD (serotonin deficit, dopaminergic salience, compulsive monitoring); and social media's amplification of the jealousy system. The Vedic classification of Irshya (jealousy) as one of six inner enemies (Arishadvargas), Patanjali's prescription of Mudita (sympathetic joy) as antidote, and the Bhagavad Gita's identification of anasuya (freedom from jealousy) as prerequisite for wisdom are presented as the ancient framework that anticipated the neuroscience of jealousy's social comparison and threat-detection mechanisms.
