Love and envy linked by same hormone oxytocin

A new study carried out at the University of Haifa has found that the hormone oxytocin, the “love hormone,” which affects behaviors such as trust, empathy and generosity, also affects opposite behaviors, such as jealousy and gloating. “Subsequent to these findings, we assume that the hormone is an overall trigger for social sentiments: when the person's association is positive, oxytocin bolsters pro-social behaviors; when the association is negative, the hormone increases negative sentiments,” explains Simone Shamay-Tsoory who carried out the research.

Previous studies have shown that the oxytocin hormone has a positive effect on positive feelings. The hormone is released in the body naturally during childbirth and when engaging in sexual relations. Participants in an experiment who inhaled the synthetic form of the hormone displayed higher levels of altruistic feelings, and it is supposed that the hormone plays an important role in the formation of relationships between people.

However, in earlier studies carried out by other investigators with rodents, it was found that the hormone is also related to higher levels of aggression. Therefore, it was decided to examine whether the hormone also affects negative social sentiments.

The present study, which was published in the journal Biological Psychiatry, included 56 participants.
