Cold plunge duration depends mainly on water temperature and experience level.
In general, colder water requires shorter exposure times. Beginners typically start with shorter plunges and gradually increase duration as their tolerance improves.
Your experience level, tolerance, and recovery goals can all influence how long you stay in cold water. Many people also practice breathing techniques to stay calm and steady during a plunge.
