Social factors can be as important to health as biology. So, how our society approaches social issues matters for our collective mental health. In this episode, we zoom in on one social determinant of health - housing - and explore in depth its relationship with mental health. Our guest, Dr. Katherine Koh, brings a humanistic and clinical perspective as a psychiatrist with Boston Healthcare for the Homeless, to help us understand the causes, consequences, and solutions at the intersection of homelessness and mental health.
