Oxytocin has been dubbed the “love hormone” for its role promoting social bonding, altruism and more. In a new study from Duke University, men reported a greater sense of spirituality shortly after taking oxytocin and a week later.
Participants who took oxytocin also experienced more positive emotions during meditation, said lead author Dr. Patty Van Cappellen, a social psychologist at Duke.
“Spirituality and meditation have each been linked to health and well-being in previous research,” Van Cappellen said. “We were interested in understanding biological factors that may enhance those spiritual experiences.
“Oxytocin appears to be part of the way our bodies support spiritual beliefs.”
Researchers note that all study participants were all male, therefore, the findings apply only to men. In general, oxytocin operates somewhat differently in men and women, Van Cappellen added.
Oxytocin’s effects on women’s spirituality still needs to be investigated.
The results appear online in the journal Social Cognitive and Affective Neuroscience.
Oxytocin occurs naturally in the body. Produced by the hypothalamus, it acts as a hormone and as a neurotransmitter, affecting many regions of the brain.
It is stimulated during sex, childbirth, and breastfeeding. Recent research has highlighted oxytocin’s role in promoting empathy, trust, social bonding, and altruism.
Researchers tested the way in which oxytocin might influence spirituality by administering the hormone to one group and a placebo to another.
They discovered that those who received oxytocin were more likely to say afterwards that spirituality was important in their lives and that life has meaning and purpose. This was true after taking into account whether the participant reported belonging to an organized religion or not.
Participants who received oxytocin were also more inclined to view themselves as interconnected with other people and living things, giving higher ratings to statements such as “All life is interconnected” and “There is a higher plane of consciousness or spirituality that binds all people.”
Study subjects also participated in a guided meditation. Those who received oxytocin reported experiencing more positive emotions during meditation, including awe, gratitude, hope, inspiration, interest, love, and serenity.
Oxytocin did not affect all participants equally, though.
Its effect on spirituality was stronger among people with a particular variant of the CD38 gene, a gene that regulates the release of oxytocin from hypothalamic neurons in the brain.
