How does cold exposure increase dopamine?

Deliberate cold exposure can significantly increase dopamine levels in the brain. Andrew Huberman explains that immersing oneself in cold water, as short as 30 seconds to a couple of minutes, can lead to a notably increased release of dopamine. This boost in dopamine helps improve mood and focus, giving a heightened sense of alertness and calmness for several hours after getting out of the cold water 1 2.

Cold exposure triggers the release of norepinephrine and dopamine, with dopamine levels increasing by up to 250% over baseline levels. This dopamine increase is sustained for a long period post-exposure, enhancing overall well-being and productivity 2 3. This method is considered a natural and safe way to elevate dopamine levels and leverage them for mental clarity and sustained motivation throughout the day 4 1.
