Cold plunging is often used as a short, controlled exposure to help train the body’s stress response. Studies show brief cold exposure can increase alertness when practiced consistently and safely.
How It Feels After
Many people describe feeling clear, steady, and awake after a plunge. This comes from how cold activates the nervous system, then allows it to settle.
Consistency Beats Intensity
Short, repeatable sessions matter more than pushing colder or longer. Recovery routines work best when they’re sustainable.
