Grief vs. Depression

Grief and depression are distinct processes, despite sharing overlapping symptoms like loss of appetite or sleep challenges. Grief is a process with a beginning, middle, and end, requiring remapping of neural circuits.

Three Dimensions of Relationships

Our brain maps relationships with people, animals, or things across three dimensions: space (where they are), time (when we expect to see them), and closeness (emotional attachment). These dimensions are interwoven in our neural framework.

Inferior Parietal Lobule

This specific brain area is uniquely activated when processing changes in physical distance between objects, temporal spacing of sounds, and emotional distance to people. It's central to how our brain maps relationships.

Episodic Memory

These are conscious recollections of experiences with someone, an animal, or a thing, including where and when events happened. In grief, these memories persist and are linked to attachment, making it hard to uncouple the relationship from space and time.

Counterfactual Thinking

This refers to 'what-if' scenarios (e.g., 'What if I had called them earlier?'). Such thinking is an infinite landscape of possibility, closely tied to guilt, and detrimental to adaptively moving through grief as it strengthens maladaptive bonds.

Oxytocin and Yearning

Oxytocin is a hormone/peptide involved in pair bonding and attachment. Higher levels of oxytocin receptors in brain regions associated with craving and pursuit (like the nucleus accumbens) are linked to more intense yearning in grief.

Vagal Tone

Vagal tone refers to the activity of the vagus nerve, which is bidirectional between the brain and body and influences heart rate. Increased vagal tone, often modulated by breathing, can help access real somatic feelings of attachment, supporting adaptive grieving.

Complicated Grieving

This is a prolonged form of grief where individuals face immense challenges in moving through the grieving process. It is associated with significantly higher cortisol levels in the late afternoon and evening compared to non-complicated grieving.

Rational Grieving

This is an adaptive approach to grief that involves a clear acceptance of the new reality (the loss) while simultaneously holding onto and anchoring to the depth and intensity of the emotional attachment, consciously distancing from episodic memories that trigger maladaptive seeking behaviors.

Neuroplasticity

Neuroplasticity is the brain's ability to rewire its connections. It is crucial for remapping the neural circuits associated with relationships after a loss and is primarily triggered by intense experience and consolidated during deep sleep and non-sleep deep rest (NSDR).

?
How does the brain map our relationships with others?

The brain maps relationships across three dimensions: space (where people are), time (when we expect to see them), and closeness (emotional attachment). These dimensions are interwoven to form our deep bonds.

?
How does grief differ from depression?

While grief and depression can have overlapping symptoms, they are distinctly different processes. Grief is a natural process of remapping neural circuits after a loss, whereas depression is a clinical disorder.

?
Why do people continue to 'look' for a lost loved one?

The brain continues to make predictions based on a deep catalog of episodic memories, leading to an expectation that the lost person will be in a certain place or time. This is a normal activation of the brain's attachment map.

?
Why do individuals experience grief at different rates?

Differences in grieving rates can be attributed to both psychological and neurochemical/biological factors, such as individual variations in oxytocin receptor expression in brain regions associated with craving and pursuit.

?
How can emotional disclosure, like writing, help in the grieving process?

Emotional disclosure can be powerful for engaging bodily and mind states associated with attachment. It is particularly beneficial for individuals with higher vagal tone, who are better able to access real somatic feelings of attachment.

?
What is the role of cortisol rhythms in complicated 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, indicating a dysregulated stress response.

?
How can foundational biology support adaptive grieving?

Optimizing foundational biology, particularly by getting adequate sleep and establishing normal cortisol rhythms (e.g., by viewing morning sunlight), positions individuals to navigate the grief process more adaptively.

1. Dedicate Time for Grieving

Set aside a specific period (5-30 minutes) to deeply feel your attachment to the lost person, animal, or thing. During this time, consciously prevent counterfactual thinking (‘what-ifs’) and disengage from guilt, as these strengthen maladaptive bonds.

2. Uncouple Attachment from Space-Time

Engage in ‘rational grieving’ by clearly accepting the new reality that the lost entity no longer exists in the same space-time. Simultaneously, anchor to the depth and intensity of the attachment, pushing off from episodic memories that trigger a search for them in current reality.

3. Optimize Sleep for Grief Recovery

Prioritize getting adequate sleep nightly, as neuroplasticity (the brain’s rewiring process crucial for remapping after loss) primarily occurs during deep sleep.

4. Regulate Cortisol with Morning Light

Establish a healthy cortisol rhythm by viewing sunlight shortly after waking. This helps achieve an early-day cortisol peak and low levels later, which is associated with non-complicated grieving and a properly regulated autonomic nervous system.

5. Utilize NSDR for Neuroplasticity

Incorporate Non-Sleep Deep Rest (NSDR) protocols into your routine for 10-30 minutes, potentially multiple times a day. NSDR has been shown to accelerate neuroplasticity, aiding the brain’s rewiring process during grief.

6. Seek Professional Grief Support

Access a trained professional such as a psychologist, psychiatrist, or bereavement group for proper support. These professional approaches are compatible with and complementary to science-based tools for navigating grief.

Grief is the process of uncoupling, unbraiding, and untangling that relationship between where people are in space, in time, and our attachment to them.

Andrew Huberman

The best way to approach moving through grief is actually to remap these dimensions while maintaining the close sense of attachment to the person by not in any way trying to undermine the intensity of the attachment or how important it was to you.

Andrew Huberman

These counterfactual modes of thinking are an infinite landscape of possibility, and they are very closely tied to guilt.

Andrew Huberman

It does not necessarily mean that you are more capable of attachment than people who move through grief more quickly.

Andrew Huberman

Everything exists in a context of our baseline physiology.

Neuroplasticity the literal rewiring of connections occurs during deep sleep and in what I call non-sleep deep rest or NSDR.

Dedicated Time for Grieving

Andrew Huberman
  1. Set aside a dedicated period of 5-30 minutes.
  2. Feel deeply into your closeness and attachment to the lost person, animal, or thing.
  3. Actively try to prevent counterfactual thinking ('what-ifs').
  4. Actively try to disengage from any feelings of guilt.

Optimizing Foundational Physiology for Grief

Andrew Huberman
  1. Get adequate sleep at night.
  2. Establish as normal a pattern of cortisol as possible.
  3. View sunlight very close to waking; if no sun, turn on as many bright lights as possible in your environment.

Rational Grieving Practice

Andrew Huberman
  1. Dedicate a period of 5-45 minutes, perhaps every day or every other day, depending on capacity.
  2. Clearly accept the new reality that the person, animal, or thing no longer exists in the same space-time dimensionality.
  3. Anchor to the depth and intensity of the attachment that existed, understanding it as a real component of yourself.
  4. Consciously push off from episodic memories that lead to looking for the person in your current reality, as these expectations are maladaptive.
  5. Engage in Non-Sleep Deep Rest (NSDR) protocols for 10-30 minutes, potentially multiple times a day, to accelerate neuroplasticity.
