Defining Grief vs. Grieving: Loss as a Learning Process
Huberman introduces Dr. Mary-Frances O’Connor and frames grief as a universal but poorly understood process. O’Connor distinguishes between grief (acute waves of emotion) and grieving (the evolving trajectory over time), using a stock market analogy to explain variability and overall movement toward adaptation. They discuss why grief never fully disappears and how grieving is fundamentally learning how to live with the loss.
- •Grief is the natural physical, emotional, and mental response to losing someone very close.
- •Grief can be measured in the moment (“how much grief are you feeling right now?”).
- •Grieving is the process of change in grief over time—like a volatile but trending stock market.
- •Waves of grief can appear decades later without implying failure to ‘move on.’
- •The aim is not to eliminate grief but to function with it and grow from the experience.
- 9:00 – 30:00
Attachment, ‘Gone but Everlasting,’ and Why Death Confounds the Brain
They explore how attachment systems evolved for situations where absence means ‘go find them’—a logic that breaks under death. O’Connor introduces her ‘gone but everlasting’ framework: consciously we know someone is dead, but our attachment neurobiology still encodes them as accessible somewhere. Moments when these two streams collide generate acute waves of grief.
- •Attachment bonds form an implicit belief: “I’ll always be there for you; you’ll always be there for me.”
- •In living relationships, absence should trigger increased mental focus and searching behavior.
- •Death creates a conflict: cognitively we know they’re gone; implicitly we feel they must still exist ‘out there.’
- •Grief waves often arise at the instant we become aware these two beliefs cannot both be true.
- •This conflict explains experiences like reflexively texting a deceased loved one.
- 30:00 – 41:00
Sudden vs. Anticipated Loss and the Limits of ‘Preparation’
Huberman asks whether knowing a loss is coming makes grieving easier. O’Connor explains that while anticipatory experiences (hospice goodbyes, closure conversations) help construct coherent narratives, they don’t fully penetrate attachment biology. People may logically know a death is coming, yet still describe it as ‘sudden’ because the attachment system resists learning that the person is truly gone.
- •Anticipated loss allows for farewell rituals (“I love you, thank you, I forgive you…”), which aids later reflection.
- •Nonetheless, many bereaved still experience the death as ‘sudden’ because the attachment belief is non-rational.
- •Automatic behaviors (reaching for phone, expecting a text) persist even after long illness and death.
- •Grieving includes transforming one’s understanding of the relationship to a non-earthly or internal bond.
- •Internal conversations and re-evaluations of the relationship can continue long after physical death.
- 41:00 – 1:05:00
Continuing Bonds, Integration, and Reframing ‘Letting Go’
They challenge the cultural notion that healing means ‘letting go’ of the deceased. O’Connor reframes adjustment as integration: maintaining an inner relationship while adapting to a world where the person is absent physically. She uses her own experience losing her mother and evolving that relationship posthumously to illustrate how forgiveness, gratitude, and identification can deepen over time.
- •Historically, religions and cultural systems gave frameworks for where the dead ‘are’ and how to relate to them.
- •Modern secular culture often lacks shared scripts for continuing bonds and grief rituals.
- •O’Connor differentiates between ‘recovery’ and ‘integration’—aiming for the latter.
- •An internalized relationship can progress: forgiveness, new understanding, and ongoing dedication (“I’m doing this for you, Mama”).
- •Integration reduces guilt and rumination and frees energy to invest in living relationships and meaningful activities.
- 1:05:00 – 1:30:00
Dopamine, Yearning, and the Reward Circuits of Attachment
O’Connor describes her neuroimaging work showing that yearning for a deceased loved one strongly correlates with activation in the nucleus accumbens and adjacent reward-learning structures. They discuss why this doesn’t mean we’re ‘addicted’ to loved ones; rather, attachment shares circuitry with homeostatic needs like thirst. Grieving then requires finding new ways to meet attachment needs once the primary figure is gone.
- •When bereaved people see photos of their deceased loved ones, memory and emotion areas activate in all participants.
- •The unique marker of intense yearning is greater activation in the nucleus accumbens and ventral striatum.
- •This area mediates wanting and effort, not just pleasure—“how much effort would you expend to see them again?”
- •Attachment is likened to thirst: a survival need monitored by homeostatic systems, not an addiction.
- •Grieving includes redirecting attachment energy: sustaining an inner bond while cultivating other attachment figures or sources (relationships, spirituality, nature, self).
- 1:30:00 – 1:54:00
Support Systems, Rituals, and the Public Health Model of Bereavement
They examine how cultural practices—from Irish wakes to shiva—provide structure, community, and ‘grief literacy.’ O’Connor argues that contemporary Western societies have lost many shared mourning frameworks, leaving individuals to navigate intense reactions alone. She introduces the public health model of bereavement support, which treats grief as a predictable medical risk window requiring system-level responses, not just individual coping.
- •Rituals like wakes normalize death, model varied emotional responses, and organize communal care.
- •Many modern people are disconnected from religious or cultural grief scripts, leading to confusion and isolation.
- •Epidemiologic data show dramatic spikes in mortality risk for the newly bereaved (e.g., 21x heart attack risk day of death).
- •A public health approach would include routine assessment (e.g., blood pressure), education, and tiered support (community groups to specialized therapy).
- •Attachment co-regulation (hugs, presence, grooming analogs in primates) is a key mechanism by which communities protect bereaved individuals.
- 1:54:00 – 2:25:00
The Grieving Body: Co‑Regulation, Medical Risk, and Aspirin Studies
O’Connor elaborates on how attachment figures act as ‘external pacemakers’ that help regulate heart rate, blood pressure, and stress hormones. Their sudden absence forces the body to relearn self-regulation under heavy load. She describes lab studies showing large blood pressure spikes during grief waves and exploratory work on using baby aspirin as a cardioprotective measure in early bereavement.
- •Partners buffer physiological stress: a simple hug can lower blood pressure and heart rate.
- •After loss, entering an empty house requires new cardiovascular regulation without that external pacemaker.
- •Grief waves are associated with transient but significant cardiovascular strain, especially in high-grief individuals.
- •Exploratory studies administering low-dose aspirin in the first weeks after bereavement showed cardioprotective effects, motivating calls for large-scale trials.
- •O’Connor compares bereavement to pregnancy: not a disease, but a high-risk, highly physiological transition deserving proactive monitoring and support.
- 2:25:00 – 2:49:00
Compartmentalization, Emotional Waves, and Building a Coping Toolkit
The discussion turns to how people manage grief alongside daily functioning. Huberman shares experiences of ‘pushing down’ intense feelings to get through obligations. O’Connor clarifies that emotions are outputs of bodily and cognitive states; tools that change those states (movement, breathing, progressive muscle relaxation) can shift emotional experience. They emphasize the value of time-bound suppression for specific tasks, balanced with intentional spaces to feel grief fully.
- •Emotions reflect underlying bodily and cognitive configurations; targeting those systems can indirectly change feelings.
- •Healthy suppression (e.g., in a pitch meeting) is a valid short-term tool but problematic as a sole strategy.
- •Progressive muscle relaxation (PMR) proved especially effective for bereaved participants, even more than mindfulness in O’Connor’s study.
- •PMR can be deployed anywhere—at work, in bed, in public—to reduce physiological arousal and help ‘ride’ a wave of grief.
- •Effective grieving involves a varied toolkit and oscillation: allowing puddles of tears, then re-engaging with tasks and relationships.
- 2:49:00 – 3:21:00
Alcohol, Short-Term Tools, and Supporting the ‘Grieving Patient’
Huberman raises the paradox of cultures encouraging alcohol in early mourning despite clear long-term harms. O’Connor recounts having a beer for breakfast the morning after her mother died and frames alcohol as one possible tool in a larger toolkit—sometimes appropriate acutely, but dangerous as a chronic coping strategy. She returns to the idea that, since bereavement is so physiologically taxing, we should deliberately support the grieving body through medical care, relational care, and context-specific tools.
- •Low-dose alcohol can transiently disinhibit, facilitate crying, and promote social sharing in some early grief contexts.
- •Repeated or heavy use to avoid feelings undermines sleep, health, and natural grieving processes.
- •Her aspirin pilot underscores the need for concrete biomedical support during the highest-risk windows, not just psychosocial sympathy.
- •Grief support could routinely include basic physiological checks (blood pressure, medication review) alongside emotional coping guidance.
- •The goal is enabling the body to survive and adapt through the transition, not abolishing grief itself.

Suicide Loss, Rumination, and Finding a Story That Quells the Loop
They address grief after suicide, distinguishing between the complex causes of suicide (outside O’Connor’s main expertise) and the distinctive challenges for survivors. O’Connor describes the ‘would’ve-could’ve-should’ve’ thought patterns—endless mental simulations that always end with the person living—and how they trap people in protest and guilt. The work becomes learning skills to disengage from unanswerable questions and finding a narrative that feels true enough to quiet the loop and allow presence in current life.
- •Grief after suicide often involves suddenness, violence, and intense meaning-searching, making adaptation harder.
- •The brain can generate infinite counterfactual scenarios; each one assumes an impossible alternate outcome (survival).
- •There is no endpoint to solving ‘if only’ questions; the helpful move is shifting how we relate to the thoughts themselves.
- •Practical strategies include changing physical context, activity, or attention when rumination starts, and sometimes constructing a compassionate narrative (“maybe they needed that”) that feels bearable.
- •The criterion is not objective truth but whether a story allows the bereaved to re-enter the present and engage with life.
- 3:45:00 – 4:11:00
Religion, Meaning, and Contemplating Death as Preparation for Grief
They explore how religious and philosophical systems can both support and stress grieving individuals. Pre-loss beliefs about death and afterlife, as shown in a landmark longitudinal study of older couples, predict lower grief severity when loss eventually occurs. At the same time, devastating loss can provoke spiritual crisis. O’Connor suggests separating the question of whether beliefs are ‘true’ from whether they are helpful in organizing experience and providing path, community, and language.
- •Religions provide community, rituals, and explanations for what happens after death—all key supports for mourners.
- •Loss can also shake prior beliefs, triggering existential or spiritual questing that adds complexity to grieving.
- •A long-term study (Changing Lives of Older Couples) found that people with pre-existing frameworks for life and death (religious or philosophical) later showed less intense grief.
- •Contemplating mortality (rather than avoiding it) can motivate living more fully and preparing relationships (saying “I love you, I’m grateful, I forgive you, please forgive me”).
- •O’Connor sees awe and transcendence even in the neuroscience of attachment and epigenetic bonding—two literally becoming one at the level of the brain.

Oscillation, Good Outcomes, and Redefining ‘Healing’ After Loss
In closing, they synthesize the conversation around the idea of oscillation: mental health in grief is the capacity to move between attending to the loss and engaging in life-restoring tasks and roles. O’Connor emphasizes that there is no single ‘good’ outcome; legitimate paths include new relationships, spirituality, service, nature, or deepened self-care. Huberman notes that trying to shortcut grief often prolongs it, and O’Connor reiterates that grief is both painful and a profound teacher about attachment, resilience, and what it means to be alive.
- •The dual process model: oscillating between loss-oriented and restoration-oriented coping predicts healthier adjustment.
- •Avoidance can delay learning and often amplifies fear and intrusive memories over time.
- •Good outcomes are diverse: new partners, no partners, spiritual transformation, devotion to nature, or self-nurturance can all satisfy attachment needs.
- •Grief reveals both how much life can hurt and how resilient humans can be.
- •Grieving, if supported and not pathologized, can deepen authenticity, gratitude, and engagement with finite time.
