    Press/Media: Expert comment

    Description

    Your body's first reaction to a plunge in chilly water is the "cold shock" response. Your heart rate jumps. Stress hormones spike. You gasp suddenly, and may hyperventilate.

    Your reward if you stay in long enough to endure these initial excruciating moments? You start to shiver.

    To the uninitiated, it may not be obvious why the practice of cold plunging has attracted a huge following in recent years.
