Summary
Andrew Huberman explains how to optimize brain chemistry by leveraging dopamine, epinephrine, serotonin, and acetylcholine. He details how these neuromodulators fluctuate throughout the day and offers science-based tools to influence them. Strategies include morning sunlight and cold exposure for dopamine, exercise and breathing for epinephrine, choline-rich foods for acetylcholine, and gratitude or myo-inositol for serotonin.
