What experts say
A
Andrew Huberman
Stanford neuroscientist
"Deliberate cold exposure triggers a significant release of dopamine and norepinephrine that can last for hours. 11 minutes total per week is effective."

Tim Ferriss
Author & podcaster
"Cold exposure is one of my keystone habits. The mental benefits of voluntary discomfort translate to other areas of life."
Our take
The benefits are real but you can start with cold showers for free. If you want a dedicated setup, Plunge is the most popular. 2-3 minutes at 50°F is effective—no need to go extreme.
