Summary

The Ritual of Gratitude: Kissing the Brain

Christina Costa, a psychologist and former middle school teacher, shares a childhood classroom ritual of 'kissing your brain' — tapping fingers to lips, then to the head, as a gratitude gesture. This simple act symbolized appreciation for their efforts and was a joyful part of her teaching. Later, as a neuroscience PhD and researcher, she revisited this practice during her own medical crisis, finding it a meaningful way to cope with her diagnosis.

Facing a Brain Tumor and Rejecting the Fight Narrative

After experiencing severe migraines, Christina was diagnosed with a large brain tumor. She shares her profound fear and the emotional shift from adopting the 'fighter' persona, which she found exhausting and burdensome, to embracing a perspective rooted in gratitude. She discusses how societal and medical language often frame illness as a war, but she advocates for a more compassionate, gratitude-based approach that allows acceptance and peace.

The Science of Gratitude and Brain Rewiring

Christina explores scientific research on gratitude, illustrating how it activates parts of the brain like the medial prefrontal cortex involved in emotion regulation. She emphasizes that gratitude can physically rewire neural pathways through neuroplasticity, making emotional resilience more accessible over time. She details her personal practice of daily gratitude exercises during her treatment, which helped her foster peace amid adversity.

Practical Applications and Encouraging Resilience

Sharing her own journey, Christina encourages others facing tough challenges to practice gratitude and love their bodies unconditionally. She highlights the importance of community support, medical gratitude, and mental resilience. Her message is one of empowerment, showing that even amidst life's unexpected hurdles, gratitude can serve as a powerful tool to foster resilience and well-being.

Show notes

When a psychologist who studies well-being ends up with a brain tumor, what happens when she puts her own research into practice? Christina Costa goes beyond the "fight" narrative of cancer — or any formidable personal journey — to highlight the brain benefits of an empowering alternative to fostering resilience in the face of unexpected challenges: gratitude.
