Cold plunge pools are small, shallow pools filled with cold water, typically ranging from 50°F to 60°F (10°C to 15°C). They are often used for recovery after intense exercise or as part of a wellness routine. The cold water can help reduce muscle soreness, improve circulation, and promote relaxation. These pools are commonly found in spas, gyms, and wellness centers, and are often used in conjunction with hot tubs or saunas. The practice of alternating between hot and cold water is known as contrast therapy, which is believed to enhance overall health and well-being.
