Why you should never spank your daughter
Children who are spanked don't have the option to flee or fight – they must submit to the pain and violence without grabbing, blocking, or defending against the assault to their body. Corporal punishment triggers the release of cortisol.
Having elevated levels of cortisol for a short period of time is okay, but if this fear response is experienced repeatedly it can damage a young brain and lead to diseased neural networks. Researchers also say that repeated elevations of cortisol can result in a child becoming sensitized to fear, making it easier for them to experience danger and pain and normalize abnormal behavior. Think about how many adults who were hit as children can’t remember the trauma and fear they actually felt at the time but say that being hit was a “good” for them because they’ve only held onto the rationalizations used to justify the violence against them.
