Time Doesn't Heal: What 20 Years of Research Actually Shows

We've been told time heals all wounds. Go back to work. Stay busy. But what if decades of stress are still rewriting the body right now? Dr. Karestan Koenen, a Harvard researcher who has followed 100,000 women over twenty years, shares what she's discovered about how unaddressed trauma doesn't fade—it becomes biology. In this conversation, we explore why major disease studies have ignored trauma, how stalking affects women's heart health, and what epigenetics reveals about catching these changes early.
