The Neurochemistry of Cold: Dopamine, Oxytocin, Serotonin

TJ Power on how cold exposure influences the four major neurotransmitter systems—dopamine, oxytocin, serotonin, endorphins—and what that means for mood, motivation, and connection.

Key Insights

Cold triggers sustained dopamine elevation (up to 250% baseline)

Oxytocin release enhances pair-bonding and social connection through shared challenge

Serotonin pathways activated through improved mood regulation

Endorphins provide natural analgesia—trained through repeated exposure

"The body adapts to what you consistently demand of it—controlled stress builds resilience when applied deliberately."
