The Science & Process of Healing from Grief | Huberman Lab Essentials

Understanding Grief and Its Process

• Grief is a process that has a beginning, middle, and end, and understanding where one is in this process can be beneficial for predicting its duration and maintaining functional capacity in life 10s.
• The experience of people is mapped in three dimensions: space, time, and closeness, which are essential for establishing close bonds with people and require remapping when someone is lost 42s.
• Grief and depression, although similar in some ways and having overlapping symptoms such as loss of appetite and challenges sleeping, are distinctly different processes 2m6s.
• The five stages of grief, including denial, anger, bargaining, depression, and acceptance, were introduced by Elizabeth Kubler Ross, but brain imaging studies and more in-depth psychological evaluations have shown that these stages are not always applicable 2m6s.

Neurological Dimensions of Attachment and Grief

• Brain imaging studies, such as functional magnetic resonance imaging (fMRI), have found that the brain areas associated with motivation, craving, and pursuit are activated in states of grief, and that attachments are represented in the brain through the dimensions of space, time, and closeness 2m6s.
• The dimensions of space, time, and closeness are crucial for understanding grief, as they govern how attachments are formed and broken, and experiments using brain scanners have been conducted to illustrate how these dimensions work together to support relationships and the grieving process 2m6s.
• The brain areas responsible for creating visual perceptions, such as the visual cortex, are activated when individuals participate in experiments involving the distance between objects, and a brain area tuned to the distance between objects, referred to as proximity, is also activated 10s.
• The brain areas associated with auditory perception are active when subjects listen to tones spaced from one another, and certain brain areas are uniquely tuned to the spacing of sounds, independent of the sounds themselves, and are activated in response to changes in the spacing between sounds 42s.
• Experiments involving images of people and faces, with varying emotional relationships and distances, show that the same brain area is activated in response to changes in physical spacing, temporal spacing of sounds, and emotional distance, which is the inferior parietal lobule 2m6s.
• The inferior parietal lobule is a brain area that is uniquely activated in response to changes in physical spacing, temporal spacing, and emotional distance, and it is not necessary to know the name or location of this brain area to understand its significance in relation to grief and attachment 2m6s.

The Role of Space, Time, and Closeness in Relationships

• The map of people in an individual's brain is not just a map of emotional closeness, but is interwoven with the map of physical space and time, including when they were last seen, when they are likely to be seen again, and how much time it would take to reach them 2m6s.
• The nervous system's ability to make predictions is a key function, and one of the most powerful aspects of attachments to people, animals, and things is the ability to predict when they will be seen again and how much time it will take to see them 2m6s.
• All relationships are mapped in the brain and body through three dimensions: space, time, and closeness or proximity, including proximity in space, proximity in time, and proximity of attachment, which refers to how close or bonded an individual is to someone 2m6s.

The Grieving Process and Mental Mapping

• The process of grieving involves reordering a mental map that associates a person, animal, or thing with feelings of attachment, space, and time, which is necessary after a loss, such as a death, because the brain continues to make predictions about the person's presence based on episodic memories 10s.
• Episodic memories, which are conscious recollections of experiences with someone or something, persist after a loss and are linked to feelings of attachment, making it difficult to uncouple the attachment from the other dimensions of the map, leading to a sense of disorientation and yearning 1m42s.
• The brain's neural activity, referred to as reverberatory activity, continues to function in a way that puts a person into an action state of seeking the lost individual, looking for them in familiar locations, and expecting them to contact them, which is immensely disorienting 2m6s.
• It is normal for people to keep looking for a lost person or thing because their brain is making predictions based on a deep catalog of episodic memories, and these expectations are entirely normal, even if the person or thing is no longer present 3m10s.
• The reordering of the mental map required to move through the grieving process involves remapping the dimensions of closeness, space, and time, while maintaining a close sense of attachment to the person, and psychologists and neuroscientists agree that this can be achieved by acknowledging and understanding the attachment without trying to undermine its intensity 4m30s.
• The process of remapping involves acknowledging the attachment and making an effort to shift one's mindset to understand that the attachment is real but will be uncoupled from the dimensions of space and time, which is a complicated process that requires holding and registering two things at once 6m40s.

Strategies for Processing Grief

• To process grief, it is helpful to set aside a dedicated period of time, such as 5-30 minutes, to feel deeply into the closeness and attachment to the person, animal, or thing that has been lost, while consciously trying to prevent counterfactual thinking, which is closely tied to guilt, and can strengthen emotional bonds 10s.
• Counterfactual thinking, or "what if" thinking, can create an infinite landscape of possibility and is closely tied to guilt, making it difficult to uncouple emotional attachment from episodic memory, and dedicated blocks of time can help to access emotional connection while starting to uncouple other nodes of memory 10s.

Individual Differences in Grief and the Role of Oxytocin

• The experience of grief can vary greatly between individuals, even if they are both intensely attached to the same person, and it is impossible to truly know how someone else feels, as their expression or body language may not accurately represent their internal emotions 2m6s.
• Research suggests that the molecule oxytocin, a hormone/peptide involved in pair bonding, lactation, and social attachment, may play a role in the intensity of grief, with some individuals experiencing a stronger yearning aspect of grief due to their oxytocin levels 2m6s.
• Studies on prairie voles, a species of animal that can be either monogamous or non-monogamous, have provided insight into the role of oxytocin in attachment and grief, with monogamous prairie voles working harder to reunite with their mates after separation, suggesting a possible link between oxytocin and the intensity of emotional attachment 2m6s.
• The patterns of oxytocin receptors in the brain are interesting, particularly in monogamous prairie voles, which have more oxytocin receptors in the nucleus accumbens, a brain area associated with motivation, craving, and pursuit, compared to non-monogamous prairie voles, indicating a capacity to link attachment circuitry to reward pathways 10s.
• People who experience intense grief and a deep yearning to reconnect with a lost person, animal, or thing often have heightened levels of oxytocin receptors in brain regions associated with craving and pursuit, which can lead to persistence in trying to reach into the past or engage in wishful thinking 2m6s.
• The presence of more oxytocin receptors in the brain area associated with motivation and pursuit does not necessarily mean that someone is more capable of attachment than others, and people move through grief at different rates due to psychological, neurochemical, and biological factors 2m6s.

Emotional Disclosure and the Vagus Nerve in Grief

• Allowing oneself to feel the attachment to somebody can accelerate or support adaptive transitioning through grief, and a study published in the journal Biological Psychology explored the concept of emotional disclosure and its effect on the grieving process 6m30s.
• The study examined the effectiveness of written disclosure of emotional connection to a lost person as a way to move through the grieving process, and it also investigated the role of the vagus nerve, a bidirectional nerve pathway between the brain and body, in heart rate and heart rate variability 8m40s.
• The vagus nerve is associated with parasympathetic functions and can slow down the heart rate, particularly through exhales, resulting in increased vagal tone, and the study used a writing exercise to explore the impact of emotional disclosure on vagal tone in 35 participants who had experienced real loss 10m50s.
• A study was conducted where two groups of people who had lost someone were asked to write about their experiences, with one group writing a letter to the person they lost and the other group writing about their daily activities, and the goal was to see if writing about the attachment to the person who was lost would help with grief 10s.
• The study found that there was no difference between the two groups in terms of grief until they looked at the individuals with higher vagal tone, who were able to modulate their state using their breathing and body, and found that this subset of individuals benefited more from the writing exercise 2m6s.
• The study suggests that accessing states of emotionality by writing or thinking about someone can be powerful in engaging the bodily states and mind states associated with attachment, and that this can be beneficial for moving through grief, especially for those who can access real somatic feelings of attachment 42s.

Physiological Regulation and Grief

• The ability to feel the relationship between breathing, heart rate, and vagal tone is important for moving through grief, as it allows individuals to access feelings of attachment in a healthier way, rather than disengaging from them 2m6s.
• The concept of a tripartite map, which includes space, time, and attachment, is related to the idea that individuals need to be able to access and process their feelings of attachment in order to move through grief 10s.
• In addition to the neural map, there are other tools that can support healthy transitioning through grief, including baseline physiology, such as sleeping well, being awake during the day and asleep at night, and having a normal diel pattern of cortisol release 10s.

Cortisol Rhythms and Their Impact on Grief

• The release of cortisol, which is linked to temperature rhythms, can help increase temperature and lead to waking, and this diel pattern is important for overall health and functioning, including immune system function 2m6s.
• In a healthy individual, cortisol levels typically follow a pattern where they are high upon waking, peak around 45 minutes later, and then gradually drop throughout the day, reaching low levels by 4 pm and remaining low at 9:00 p.m. and throughout the night, which is closely related to the body's natural temperature regulation 10s.
• Research has explored the relationship between cortisol rhythms and grieving, particularly between complicated and non-complicated grieving, with complicated grieving being a prolonged and more challenging form of grief that requires attention, and studies have shown that individuals experiencing complicated grieving tend to have higher cortisol levels at 4 pm and 9:00 p.m. compared to those with non-complicated grieving 2m6s.
• Establishing a normal cortisol rhythm and sleep pattern is crucial for navigating the grief process, and getting adequate sleep at night is essential, with one simple way to achieve this being exposure to sunlight or bright lights upon waking, which helps regulate the autonomic nervous system and promotes a healthy cortisol rhythm 4m30s.

Rational Grieving and Adaptive Healing

• Viewing sunlight in the morning has been shown to be beneficial for regulating cortisol levels, with an early day cortisol peak and low cortisol level late in the day being immensely beneficial for being alert during the day and sleeping at night, and this can be achieved by exposing oneself to sunlight or bright lights upon waking 6m40s.
• In terms of healthy adaptive moving through grief, dedicating time to rational grieving, which involves accepting the new reality of the loss and anchoring to the attachment that existed, can be beneficial, with this time ranging from 5 to 45 minutes, and allowing individuals to process their emotions and distance themselves from episodic memories that can lead to maladaptive expectations 10m30s.
• Rational grieving involves a clear acceptance of the loss and holding on to the attachment that existed, allowing individuals to push off from episodic memories and distance themselves from them, which can help prevent complicated grief and prolonged grief disorders 12m40s.
• Understanding the node of the map, a component of the neural map, is crucial as it represents the depth of attachment and is a real component of an individual, comprising cells that literally represent attachment 10s.

Neuroplasticity and Tools for Healing

• Accessing quality sleep on a regular basis is important for emotion regulation, autonomic control, and neuroplasticity, which is a two-part process involving the triggering of plasticity and the literal rewiring of connections that occurs during deep sleep and non-sleep deep rest (NSDR) 10s.
• Practicing dedicated focusing on attachment feelings, writing about the attachment, or using NSDR scripts can trigger neuroplasticity, and these scripts are short behavioral protocols that can be done for 10 to 30 minutes to accelerate neuroplasticity 42s.
• Holding on to the attachment while being rationally grounded and avoiding holding on to the past or anticipating the person's return is a challenging but necessary cognitive process for healing from grief 42s.

Support Systems and Preparation for Grief

• Preparing oneself for grief by regulating catakolamines, such as epinephrine, and increasing vagal tone through techniques like respiratory sinus arrhythmia can help individuals grieve more adaptively 2m6s.
• Accessing a trained professional, such as a psychologist or psychiatrist, or joining a bereavement group can provide proper support for grieving, and the tools discussed can be complementary to these approaches 2m6s.
• Building episodic memories and emotional attachments can make life rich and worth living, and leaning into these memories rather than away from them can help individuals move through the grieving process 2m6s.
