Part 4/13:
Dr. Huberman describes dopamine as a "universal currency" that encourages us to seek out resources essential for survival—food, water, social bonds, and reproduction. Our baseline level of dopamine, along with transient peaks or surges, governs how motivated and satisfied we feel.
- Dopamine Peaks: Activities like eating chocolate (which increases dopamine 1.5 times), sex (2 times), nicotine (2.5 times), cocaine, and amphetamines can cause rapid, substantial dopamine surges. Exercise’s effect on dopamine varies depending on enjoyment but can also double dopamine levels in those who find it pleasurable.
