Once reserved for elite athletes, this method has surged in popularity, driven by wellness influencers, sports recovery experts, and mental health advocates.

💪 Health Benefits of Cold Plunge Therapy

Cold plunge therapy offers both physical and mental health benefits backed by research and professional opinion.

1. Reduces Muscle Soreness and Inflammation

Post-exercise soreness can delay recovery. Cold plunge therapy helps by narrowing blood vessels, reducing inflammation, and easing pain.
