The Science of Gratitude & How to Build a Gratitude Practice | Huberman Lab Podcast #47

Neurochemistry

The neurochemistry of gratitude involves key neuromodulators like serotonin, which play a significant role in activating neural circuits associated with pro-social behaviors. Andrew Huberman explains that serotonin, released from the brainstem's raphe nucleus, enhances the activity of brain areas like the anterior cingulate cortex and medial prefrontal cortex, fostering feelings of gratitude and contentment 1. These circuits encourage individuals to engage more deeply with positive experiences, promoting a sense of well-being. Huberman highlights that enhancing serotonin levels can amplify gratitude, although he advises caution with supplements like 5-HTP due to potential sleep disruptions 2.

   

Health Benefits

Gratitude practices offer profound health benefits, including reduced inflammation and improved immune function. Andrew Huberman cites a study showing that regular gratitude practices decrease amygdala activity and inflammatory cytokines like TNF-alpha and IL-6, which are linked to stress and immune response 3. This reduction in inflammation is rapid and suggests a shift in neural circuitry that positively impacts health. Additionally, gratitude enhances social relationships and resilience to trauma, providing long-lasting improvements in mental and physical well-being 4.

   

Effective Practices

Effective gratitude practices are grounded in narrative and genuine exchanges of thanks. Andrew Huberman emphasizes that merely listing things to be grateful for is less effective than engaging with stories that evoke genuine gratitude 5. Observing or receiving heartfelt gratitude activates pro-social neural circuits more robustly. Huberman suggests using narratives as cues for gratitude practices, recommending brief sessions of one to five minutes, three times a week, to maximize benefits 6.
