Dr. Mary-Frances O'Connor: Professor of clinical psychology and psychiatry at the University of Arizona, where she directs the Grief, Loss, and Social Stress Laboratory. A pioneer in the neuroscience of grief and author of 'The Grieving Body'.
What this episode covers
Andrew Huberman and Dr. Mary-Frances O'Connor explore the neuroscience and physiology of grief, framing it as the natural response to the loss of an attachment figure rather than a disease. O'Connor explains that grief lives in the brain's reward circuitry: yearning for a lost loved one activates the nucleus accumbens, much like thirst for water, because we need attachment figures for survival. They distinguish grief (the in-the-moment wave) from grieving (the long-term learning process), and unpack John Bowlby's protest-and-despair responses, the importance of social support and co-regulation, and the serious cardiovascular risks of bereavement. The conversation also covers cultural mourning rituals, alcohol's role in grief, suicide loss, religious and philosophical belief, practical coping tools like progressive muscle relaxation, and the oscillation between loss and restoration that marks healthy grieving.
The guest's own work
The Grieving Body
Mary-Frances O'Connor
“I will say that in the book that I wrote recently, 'The Grieving Body', some of these lessons have come to me because I have multiple sclerosis”— Mary-Frances O'Connor
Also referenced (named, not recommended)
On Death and Dying
Elisabeth Kubler-Ross
“So she published on Death and Dying in 1969. And you're right. It was groundbreaking, the idea that grief is more than sadness”— Mary-Frances O'Connor
The Secret Pulse of Time
Stefan Klein
“I've been motivated to read, There's a wonderful book, The Secret Pulse of Time that talks about this somewhat.”— Andrew Huberman
The Denial of Death
Ernest Becker
“If you read, 'The Denial of Death', you learn about this. So as people get closer and closer to the end their time perception changes.”— Andrew Huberman
Ghost
Jerry Zucker
“it's difficult to decide whether or not movies like Ghost. I think that was the movie, right? Where she loses her spouse or her loved one”— Andrew Huberman
The Simpsons
Matt Groening
“There's a great Simpsons episode, where Lisa Simpson has a poem about her cat, that died and she said, They said that he was sleeping. They lied.”— Andrew Huberman
Big reveals from this episode
- O'Connor reframes grief: you never 'let go' of the attachment; you integrate an ongoing internal relationship with the deceased.
- Her neuroimaging found yearning for a loved one correlates directly with activity in the nucleus accumbens, the brain's reward-learning region.
- On the day a loved one dies you are 21 times more likely to have a heart attack than any other day of your life.
- In the first three months after a wife's death, a man is nearly twice as likely to have a fatal heart attack; for women it's about 1.8 times.
- In her lab's intervention study, progressive muscle relaxation outperformed mindfulness training for helping grief.
- She argues Kubler-Ross's five stages were descriptive clinical observation that wrongly became a rigid prescription.
- O'Connor reveals she has multiple sclerosis, which deepened her empathy for living in an unpredictable body.
- Her proof-of-concept study gave baby aspirin to the newly bereaved to test whether it is cardioprotective during the high-risk period.
Worth remembering
- Her 'gone but everlasting' theory: the brain holds both that a person is dead and the implicit belief they still exist, and grief waves hit when those collide.
- Yearning for a loved one is like thirst, not addiction; we have a homeostatic need for attachment figures like food and water.
- A partner acts as your 'external pacemaker'; after loss, your cardiovascular system must relearn to regulate itself alone.
- Bereaved monkey mothers carry dead infants for days to months and stop grooming themselves, and the troop's grooming hierarchy rules are suspended to care for them.
- Prairie voles undergo epigenetic changes in the nucleus accumbens within 24 hours of mating for life.
- The 'would've, could've, should've' thoughts after a suicide are an infinite loop; the solution is not answering them but learning to live given the loss.
- The 10-year Changing Lives of Older Couples study found people with a framework for understanding death had less grief severity after loss.
- A widower's line 'it was really good then, and it's really good now' captured O'Connor's idea of mental health as oscillation.
- Over time people remember the person's life rather than their death, a memory quirk that aids resilience.
- Huberman's insight she vowed to borrow: 'the only way to prolong the process is to try and shorten it.'
