In this Huberman Lab Essentials episode, I discuss interoception, the brain’s ability to sense and interpret signals from the body, which shapes our sense of self and underlies vital functions like focus, sleep, healing and emotions. I explain how the body communicates different types of information to the brain, influencing processes like digestion, heart rate and immune function. I also describe practical tools such as breathwork to regulate alertness, strategies to support gut health and reduce sugar cravings, and awareness practices to enhance interoception. By understanding and applying these tools, you can strengthen the brain-body connection to improve mood, overall health and performance. Read the episode show notes at hubermanlab.com.
