Andrew Huberman (solo) — Stanford professor of neurobiology and ophthalmology and host of the Huberman Lab podcast. This is a solo Essentials episode with no guest.
The gist
In this Huberman Lab Essentials episode, Andrew Huberman breaks down the neuroscience of gratitude and how to build a practice that actually changes your physiology. He explains that gratitude is a prosocial behavior governed by serotonin and prefrontal circuits, and that the popular approach of listing things you're grateful for is largely ineffective. Instead, the research shows that receiving genuine thanks, or vividly experiencing a story of someone receiving help, is what powerfully activates gratitude circuits. He walks through several studies showing gratitude reduces amygdala activity and inflammatory markers, shifts brain-heart connectivity, and lowers anxiety while boosting motivation. He closes with a concrete protocol: anchor the practice in a meaningful story, jot a few bullet-point cues, and spend one to five minutes feeling into the experience of received gratitude.
Big reveals
- Huberman admits he was completely surprised that an effective gratitude practice looks nothing like writing down what you're grateful for.
- Most studies show the standard 'list things you're grateful for' practice is not particularly effective.
- The most potent form of gratitude is not giving or expressing it, but receiving thanks.
- Admits the exact mechanism by which the medial prefrontal cortex reframes experience is complicated and not completely understood.
- Watching genocide survivors' stories of being helped robustly activates gratitude circuits in unrelated observers via narrative.
- In an fMRI money study, the giver's wholehearted vs reluctant intention mattered more than the amount of money received.
- A 2021 study found a regular gratitude practice reduced amygdala activity and inflammatory cytokines TNF-alpha and IL-6.
Things worth remembering
- Doing a gratitude practice even once a week can produce long-lasting improvements in subjective well-being.
- A regular gratitude practice can build resilience to both past trauma and future traumas.
- Serotonin, released from the brainstem raphe nucleus, is the main neuromodulator behind gratitude and prosocial behavior.
- You can't lie to yourself into gratitude; neural circuitry is plastic but not stupid and knows when you're faking it.
- Choosing a discomfort like an ice bath yourself produces positive neurochemical effects, while being forced into the same act produces negative ones.
- A mouse forced to run on a linked wheel shows rising blood pressure and stress hormones, unlike a mouse that chooses to run.
- A repeated gratitude practice can change resting-state functional connectivity, making fear and anxiety circuits less active and motivation circuits more active.
- Reductions in amygdala activation and inflammatory markers occurred almost immediately after the gratitude practice.
- An effective practice should be grounded in a story, take only one to five minutes, and reuse the same story each time.
