Full Body Cold Immersion
Submerging torso and legs in cold water for brief periods to trigger vasoconstriction and a stress-recovery rebound—duration and temperature matter more than bravado.
Full body cold immersion means submerging the torso and legs—not just ankles—in cold water to trigger vasoconstriction and a sharp sympathetic spike followed by parasympathetic rebound in many users. Durations of one to five minutes are common; longer is not automatically better.
Open water, plunge tubs, and cold showers differ mainly in temperature control and safety.
Common questions
-
How long should full body cold immersion last?
One to five minutes is typical for trained users. Exit if you lose fine motor control, feel chest pain, or shiver uncontrollably—rewarm gradually.
