Contrast showers involve alternating between hot and cold water during a shower. This practice is believed to stimulate circulation, improve muscle recovery, and enhance overall well-being. The hot water helps to relax muscles and open up blood vessels, while the cold water can invigorate the body and tighten the skin. Typically, a contrast shower starts with a few minutes of hot water, followed by a brief period of cold water. This cycle can be repeated several times. Many people find this method refreshing and energizing, making it a popular choice for athletes and those seeking to boost their daily routine.
