9 Key Concepts
Grief as a Motivational State
The brain views grief not just as sadness, but as a yearning or desire for something specific that is just outside reach. This involves activation of brain areas associated with motivation, craving, and pursuit, particularly the nucleus accumbens, driven by dopamine.
Three Dimensions of Relationships
Our brain maps relationships to people, animals, and things along three dimensions: space (physical proximity), time (when last seen, when expected to see again), and closeness (emotional attachment). Grief requires remapping these dimensions when a loss occurs.
Episodic Memories in Grief
These are conscious recollections of experiences with a person, animal, or thing, including where and when events happened. In grief, these memories persist and continue to drive predictions of their presence, even when logically they are gone, leading to disorientation and yearning.
Phantom Limb Analogy for Grief
Grief can be likened to a phantom limb experience, where the brain genuinely feels the presence or sensation of something that is no longer physically there. This occurs because the brain's maps of space, time, and attachment are reactivated, creating intrusive sensations or expectations.
Trace Cells
Neurons in the hippocampus and entorhinal cortex that activate when something is expected to be at a given location but is not there. These cells are responsible for representing the absence of something and are highly active in the immediate stages of grief, contributing to the feeling of expectation and yearning.
Oxytocin and Yearning
Oxytocin, a hormone involved in pair bonding and attachment, appears to influence the intensity of the yearning aspect of grief. Individuals with more oxytocin receptors, particularly in brain regions associated with craving and pursuit (like the nucleus accumbens), tend to experience more intense yearning in grief.
Vagal Tone
Reflects the degree of ongoing inhibitory regulatory influence of the vagus nerve on the heart. High vagal tone indicates a better ability to control autonomic arousal and stress, often associated with slower heart rate during exhales (respiratory sinus arrhythmia), and can influence one's capacity to move through grief adaptively.
Respiratory Sinus Arrhythmia
The natural relationship where inhales speed up the heart rate and exhales slow it down. This mechanism can be consciously trained to improve vagal tone, helping to regulate stress and emotional states, which in turn can support adaptive grief processing.
Complicated Grief
A form of grief, occurring in about one in ten people, where the grieving process does not resolve itself even after a prolonged period. It is distinct from depression and can be predicted by higher baseline levels of circulating adrenaline (epinephrine) prior to the loss.
8 Questions Answered
Grief is a distinct psychological and physiological event from depression, often not responding well to antidepressants, and is conceptualized as a motivational state of yearning rather than just sadness.
While there are different stages of grief (denial, anger, bargaining, depression, acceptance), modern science refutes the idea that everyone experiences all of them or moves through them in a linear order.
The brain maps relationships in three dimensions: space (physical location), time (when we expect to see them), and closeness (emotional attachment). These dimensions are intricately linked, and loss requires their remapping.
Our brain's deep catalog of episodic memories, linked to our attachment, continues to generate predictions of the loved one's presence in familiar spaces and times, even when we logically know they are gone.
Individual differences in grief intensity and duration can be influenced by neurochemical factors like oxytocin receptor levels in motivation centers, and higher baseline adrenaline levels can predict a greater likelihood of complicated grief.
A higher vagal tone, reflecting better control over the autonomic nervous system through practices like breathwork, can enhance the mind-body connection, allowing individuals to more adaptively access and process feelings of attachment during grief.
Individuals experiencing complicated grief tend to have significantly higher cortisol levels in the late afternoon (4 p.m.) and evening (9 p.m.) compared to those with non-complicated grief, suggesting a dysregulated stress response.
Viewing sunlight very close to waking, for 10-30 minutes without sunglasses or through a window, is the most powerful zero-cost way to establish healthy cortisol rhythms, which supports better sleep, emotional regulation, and neuroplasticity.
13 Actionable Insights
1. Maintain Attachment, Remap Space/Time
Approach grief by maintaining your deep emotional attachment to the lost person/animal/thing, while actively remapping your understanding of their location in space and time without expecting past interactions to recur.
2. Dedicated Time for Rational Grieving
Set aside 5-45 minutes regularly for “rational grieving,” deeply feeling your attachment to the lost one while consciously preventing “what-if” thinking and anchoring yourself in the present physical environment.
3. Avoid Counterfactual Thinking
Actively disengage from “what-if” thinking during grief, as this infinite landscape of possibilities is tied to guilt and strengthens maladaptive emotional bonds, hindering the remapping process.
4. Reframe Grief as Yearning
Consciously shift your perception of grief from solely sadness to a motivational state of yearning or desire for something specific, as this understanding is key to navigating the process effectively.
5. Establish New “Location” for Lost One
Form a firm mental representation of where the lost person/animal/thing now exists, according to your beliefs, to integrate them into your remapped understanding of space, time, and attachment.
6. Understand Grief’s Three Dimensions
Recognize that your brain maps relationships in terms of space, time, and closeness (attachment). This framework helps explain the disorientation of loss and guides the necessary remapping process.
7. Seek Professional Help for Grief
Access support from a trained professional (psychologist, psychiatrist, or bereavement group) if you are experiencing complicated or prolonged grief, as these conditions often require substantial expert assistance.
8. Regulate Cortisol with Morning Sunlight
View bright sunlight for 10-30 minutes shortly after waking (without sunglasses or through glass) to regulate cortisol rhythms, improve sleep, and establish a stable emotional foundation for navigating grief.
9. Avoid Evening Artificial Lights
Dim lights and avoid bright artificial screens in the evening (especially 10 PM to 4 AM) to support healthy cortisol and melatonin rhythms, crucial for quality sleep and emotional regulation during grief.
10. Increase Vagal Tone with Breathing
Practice long exhale breathing for 1-5 minutes daily, consciously slowing your heart rate during exhales and increasing it during inhales, to strengthen the mind-body connection and access feelings of attachment.
11. Utilize Non-Sleep Deep Rest (NSDR)
Engage in NSDR protocols for 10-30 minutes, potentially multiple times a day, to accelerate neuroplasticity and support the brain’s necessary reordering of connections for moving through grief.
12. Reduce Baseline Adrenaline
Proactively reduce your resting levels of epinephrine (adrenaline) through stress management tools to potentially inoculate yourself against developing complicated or prolonged grief.
13. Build Rich Episodic Memories
Actively lean into building rich episodic memories and emotional attachments with people and animals in your life, as these deep connections make life rich and are worth the eventual grief process.
6 Key Quotes
Grief is not just about sadness, it is a state of sadness, hence the activation of brain areas associated with pain and it is a state of desire and reaching for something.
Andrew Huberman
You dead are so much better than anyone else alive.
Richard Feynman
Please excuse my not mailing this, but I don't know your new address.
Richard Feynman
You can give me nothing now, yet I love you so that you stand in the way of my loving anything else. But I wanted you to stand there.
Richard Feynman
Grief in many ways is like a phantom limb.
Andrew Huberman
Dopamine is not about feeling good. Dopamine is about placing us into a state of desiring things and seeking things.

3 Protocols
Adaptive Grief Processing (Remapping Relationships)
Andrew Huberman- Set aside a dedicated period of time (5-45 minutes) to deeply feel your closeness and attachment to the lost person, animal, or thing.
- Consciously prevent engaging in 'counterfactual thinking' (what-ifs) or thoughts oriented toward past events that cannot be again.
- Hold the grief in the present moment, orienting yourself in your current physical environment, while still acknowledging the depth and richness of the attachment.
- Understand that it is normal for your mind to generate expectations of their presence, but actively work to uncouple the attachment from the space and time representation of the lost entity.
Improving Sleep & Regulating Cortisol Rhythms to Support Grief Recovery
Andrew Huberman- View bright sunlight very close to waking for 10-30 minutes daily (without sunglasses, not through a window/windshield).
- Avoid bright artificial lights, especially bright screens, in the evening (generally 10 p.m. to 4 a.m., but dim lights as much as possible).
- Access deep sleep regularly to facilitate neuroplasticity, which is essential for reordering brain connections involved in grief processing.
Building Vagal Tone for Stress & Grief Modulation
Andrew Huberman- Consciously focus on the relationship between your breath and heart rate.
- Practice slowing your heart rate while exhaling (long exhales).
- Concentrate on increasing your heart rate as you inhale (shorter inhales relative to exhales).
- Engage in this practice for 1-5 minutes per day to strengthen the vagus nerve pathways and improve your ability to control autonomic arousal.
