A new study suggests that people who are having sex aren't just saying, "Oh God," they're releasing hormones that can lead to believing in one.

A team at Duke University in North Carolina found that the release of oxytocin not only assists with social bonding and helping women push out babies, but can lead to increased religious feelings and spirituality.

“We were interested in understanding biological factors that may enhance those spiritual experiences,” social psychologist Patty Van Cappallen told Duke Today, “Oxytocin appears to be part of the way our bodies support spiritual beliefs.”
