On June 19, 1865, enslaved Black people in Galveston, Texas learned they were free. Freedom came two and a half years after the war had ended,delivered at someone else’s convenience. More than 160 years later, Black families are still catching up. Not just politically or economically but in our bodies.
What happened in Galveston was not just a historical footnote. It was a blueprint for how Black suffering gets managed in this country acknowledged just enough, just late enough, to take the edge off without ever addressing the wound. And that wound did not stay in 1865. It traveled forward in time, written into the biology of every generation that followed.
This is where science catches up to what Black grandmothers already knew. Epigenetics, the study of how lived experience changes the way our genes are expressed, without changing the genetic code itself, has shown us that trauma does not die with the person who survived it. It is passed down.The children and grandchildren of people who were enslaved, surveilled, redlined, and broken by systems did not escape that history. They inherited it, in their nervous systems, their immune responses, their relationship to safety and self.
Black Americans carry higher rates of hypertension, diabetes, anxiety, and depression; not because of genetics, but because of what systems have inscribed onto our bodies over generations. We are starting from a place of inherited biological burden. And the gap will not close with standard-issue interventions built for bodies that did not carry what ours carry.
Epigenetics also tells us that healing experiences can be passed down too. The body that learned to brace can learn to open. The nervous system that inherited fear can inherit peace. But only if the work is done.
The original Juneteenth gatherings included storytelling; the spoken transmission of identity, survival, and belonging across generations, which research now shows builds resilience and buffers the psychological effects of racism in young people. They included libations; the pouring of water or spirits to honor those who came before, to acknowledge that the living and the ancestors are in continuous relationship. They included ceremony; collective ritual that signals to the nervous system: you are safe, you are held, you are not alone.
These are not quaint traditions. They are technologies. Sophisticated, embodied, culturally specific tools for doing what no pill, no hotline, and no therapy referral has been able to do at scale for Black families: interrupt the transmission of trauma and replace it, deliberately, with the transmission of healing.
Juneteenth gives us something the mental health system cannot manufacture: a communal, culturally grounded, annually recurring moment to begin again. Not to erase what happened, but to say, out loud, together, across the table, we are more than what was done to us. And then to prove it, through practice.
To be sure, celebration alone is not enough.
Cookouts and concerts matter. Joy is resistance, and rest is revolutionary. But if Juneteenth ends without intention, we have missed the deeper call. The libation that sits in a bottle on a shelf does nothing. The story that never gets told skips another generation. The ceremony that gets replaced by a playlist heals no one. Ancestral healing technology only works when we use it : consciously, consistently, as a family practice rather than a one-day event.
This is not about guilt. It is about choosing, as families and as a people, to build something new on what we survived. That means having honest conversations across generations; with our children, our parents, our elders; about what we carry and what we are choosing to put down. It means understanding that when your child struggles, when your parent rages, when you cannot sleep or cannot feel safe or cannot stop bracing for the next blow, that is not weakness. That is epigenetics. That is history moving through a body. And it can move out of a body too, through the right kinds of healing.
This Juneteenth, make it a healing ceremony.
Here is what I am asking Black families to do: make this holiday mean something again. Pour a libation: water is enough, and speak the names of those who came before you. Sit with your children and tell them the real story, not just the date but the delay, the defiance, the survival. Let an elder in your family share something they have never said out loud. Create one new family ritual rooted in your culture and commit to it every single year. And understand that every time you do, you are not just honoring the past. You are literally, biologically, changing the future. You are rewriting what gets passed down.
Our ancestors survived so we could heal. They held on so we could let go. They passed down the wound because they had no other choice, but they also passed down the ceremony, the story, the libation, the song. On this Juneteenth may we honor their legacy by honoring our health.
