It has been proven that Oxytocin centres in your brain regulate the brain and body’s response to environmental and social challenges by reducing stress. Oxytocin reserves are located near the hypothalamus and connect areas of the brain that control behaviour and emotion. Increasing levels of oxytocin in someone suffering with PTSD can help optimize their social support by reducing stress in challenging social circumstances.
In humans, Oxytocin has been shown to enhance the processing of positive social information when compared to negative social information, this helps to increase the sense of trust in others and reverse the effects of hostile conditioning of social stimuli. This effect can increase buffering on social support and stress responsiveness which reduces the stress response in people with a history of Trauma.
