A cold plunge bath is cold water you sit in for a short time. Many people do it after sports or when they feel tired. The cold plunge bath benefits include less sore muscles, better sleep, and feeling calm. It may help your body and your mind.
What Is a Cold Plunge Bath and Why Do the Benefits Matter?
Cold Plunge refers to the act of soaking in 5-15℃ cold water for 2-15 minutes. According to the difference in water temperature, it can be divided into:
- Basic level (12-15℃): suitable for daily health care
- Advanced level (5-10℃): dedicated to sports recovery
- Extreme level (0-5℃): only for professional athletes
Unlike traditional ice compresses, cold water plunges induce systemic physiological reactions by immersing the whole body. Institutions such as Harvard Medical School use this cold stimulation as an auxiliary treatment method.
