About this episode

This episode explores how different forms of adversity affect our physical and mental health at a cellular level.

Different forms of adversity – like abuse, violence, and neglect – not only damage our physical and mental health but also change our cells. Scientific advances in the biology of adversity are showing us that in some cases, the harms of negative experiences run dangerously deep in our bodies and minds. In this episode, host Samantha Laine Perfas talks with children’s psychologist Kate McLaughlin, psychiatric epidemiologist Karestan Koenen, and cellular biologist Jason Buenrostro about what the future holds for protecting people from their worst experiences.
