Even though it may not feel like it, cold plunges or showers—even splashing cold water on your face—stimulate the calming part of your nervous system, known as the parasympathetic nervous system. Cold water activates the vagus nerve and “shocks” your body into a parasympathetic response. Your heart rate slows, vasodilation increases blood flow to your brain, happy hormones are released, and your body relaxes.
