Key Takeaways

  • Processing grief through emotional disclosure isn't a universal unlock; its efficacy hinges on your physiological state, specifically your vagal tone.
  • Research cited by Andrew Huberman shows written emotional disclosure is most impactful for individuals with a high degree of vagal tone.
  • High vagal tone enables better autonomic regulation, allowing you to genuinely access and feel the physical (somatic) sensations tied to a lost attachment.
  • This capacity to physically experience the connection, even in its absence, is crucial for adaptively moving through the grieving process.

The Method: Somatic Access Through Written Disclosure

We’ve all heard the advice: when you’re going through a tough time, write it out. Pour your heart onto the page. For ambitious founders and builders, dealing with any kind of loss, whether personal or professional, can derail focus and momentum. Huberman Lab recently explored a critical nuance to this well-trodden path, citing research from Biological Psychology that reframes how and for whom emotional disclosure truly works in processing grief.

The core of the method is simple: written emotional disclosure. This means intentionally writing about the emotional connection to someone lost, detailing the feelings, memories, and the bond itself. Huberman explains, “What this study explored was whether or not written disclosure of the emotional connection to somebody that was lost would be effective as a way for people to move through the grieving process.” The surprising finding wasn't just that it worked, but why it worked better for some than others.

The differentiator? Your vagal tone. Huberman notes, “a subset of individuals who had a high degree of veagal tone seemed to get more benefit from this writing type exercise.” Vagal tone is a measure of your autonomic nervous system’s ability to regulate itself, essentially how well your body can shift between states of stress and calm. Individuals with higher vagal tone demonstrate a greater capacity for self-soothing and emotional flexibility. For these individuals, writing isn't just intellectual processing; it's a gateway to real physical sensation.

As Huberman puts it, “accessing these states of emotionality by writing or thinking about somebody is quite powerful in terms of engaging the bodily states and the mind states associated with the attachment and that is very beneficial for moving through grief.” It’s not just about recalling the emotional bond, but about feeling it in your body—the warmth, the comfort, the specific physical echoes of that relationship. This isn't about escaping the pain; it's about deeply engaging with the full, physical reality of the attachment that was.

Where This Breaks Down: When Your System Resists

If high vagal tone is the superpower here, what happens when it’s low? Huberman's discussion makes it clear that while written disclosure is generally beneficial, its greatest impact is reserved for those whose physiology is already optimized for it. For individuals with lower vagal tone, simply attempting to write about their emotional connection might not yield the same profound results. They might struggle to access those crucial somatic sensations.

“for those that can really feel the relationship between breathing, heart rate, what we call veagal tone. Well, those people are going to be in a better position to move through grief not because they are disengaging from the feelings of attachment but because they are better able to access those feelings of attachment,” Huberman says. If your nervous system is in a constant state of low-grade stress or disregulation, you might find it harder to tap into the physical manifestation of attachment through writing or deliberate thought. It's not a lack of effort or desire to process, but a physiological hurdle in engaging the body's role in emotional healing.

This means that simply instructing everyone to "journal their feelings" without considering their underlying autonomic regulation overlooks a critical component of effective emotional processing. Without the capacity to truly feel and integrate those somatic sensations, the exercise becomes more of a mental rumination than a truly adaptive movement through grief.

What to Do With This

Stop treating emotional processing as purely a mental exercise. If you're tackling any significant emotional challenge—be it grief, the stress of a failed project, or founder burnout—first, prime your nervous system. Before you sit down to journal, reflect, or even have a tough conversation, spend 5-10 minutes actively regulating your vagal tone. Try a deliberate breathwork practice, like box breathing (inhale 4, hold 4, exhale 4, hold 4), or a short cold exposure. This isn't a distraction; it’s an investment in your physiological capacity to process emotions effectively, ensuring your efforts at emotional disclosure hit their mark rather than just adding to mental clutter.
