  Humans frequently sacrifice resources to help others——even strangers.The proximate mechanisms inducing such sacrifices are not wellunderstood, and we hypothesized that touch might provoke a sacrifice of money to a stranger.We found that touch significantly elevatedcirculating oxytocin (OT) levels but only when it was followed by an intentional act of trust.Touch followed by trust increased monetarysacrifice by 243% relative to untouched controls.We also found that women were more susceptible than men to OT release and monetarysacrifice after touch.This suggests that touch draws on physiologic mechanisms that support cooperative behaviors in humans.
