Ice baths induce vasoconstriction/dilation, thermogenesis, and cardiopulmonary responses aiding recovery.
The expert personally used this regimen to reduce his PSA from 7.8 to 0.8 and increase testosterone to 1180 ng/dL without drugs.
Ice baths appear most effective at three or fewer sessions per week.

Talk it through
Entrain shows what the experts teach, so you can make better decisions with your own clinician. It does not diagnose or prescribe. If something is worrying you, start there.
How this reading was made
Every line here comes from a doctor, scientist or coach speaking publicly, and links to the moment they said it. Entrain listens for where independent experts arrive at the same place on their own, and shows where they part ways. Mostly expert experience so far, with published research still catching up.
