The short answer
Research suggests intense cold exposure can influence catecholamines such as norepinephrine, and some studies report changes related to mood and alertness. Direct claims about dopamine should be framed carefully because protocols and measurements differ.
What this means practically
For most users, the practical takeaway is that cold exposure may support a temporary sense of alertness. It should not be treated as a medical intervention for mood disorders.
