In this Huberman Lab Essentials episode, I explain the neuroscience of grief, including how the brain maps relationships across three dimensions — space, time, and closeness — and why losing someone requires a remapping of those neural circuits. I describe how grief differs from depression, the role of oxytocin in driving yearning after a loss, and why people move through grief at different rates. I also discuss science-based tools for grieving adaptively, including how to access feelings of attachment while decoupling them from episodic memory. Finally, I explain how foundational biology — particularly sleep and cortisol rhythms — shapes our capacity to navigate the grieving process. Read the episode show notes at hubermanlab.com.
