Contrast Therapy
Hot Sauna / Cold Plunge

Our Fire & Ice room employs a contrast therapy approach, utilizing state-of-the-art variations of hot and cold temperatures. Here’s a brief overview of the advantages of contrast therapy in general.

Have you ever experienced a sprained ankle or strained your back? Perhaps you encountered a different kind of moderate injury elsewhere on your body. Odds are, when faced with such injuries, you were advised to alternate between applying heat and cold. This is a form of contrast therapy.

Contrast therapy, deeply rooted in traditional naturopathic medicine, is a widely embraced method for rehabilitation and recovery. While this practice seems new and trendy to some, the reality is that various cultures have utilized some form of contrast therapy for centuries, if not millennia.

Although these cultures may not have comprehensively understood the physiological mechanisms behind contrast therapy, the tangible benefits in terms of pain relief and overall well-being were compelling reasons to incorporate it into their regular health routines.

Presently, contrast therapy is primarily utilized by athletes and fitness enthusiasts seeking swift recovery from workouts or alleviation of muscle soreness and injuries. However, its benefits extend beyond the realm of athletics, proving effective for individuals grappling with various chronic, mental, and physical conditions, irrespective of athletic status.

Welcome to the ultimate contrast therapy experience! Core iV wanted to offer only the very best; combining the rejuvenating power of Sun Home’s Cold Plunge Pro and Sunlighten’s mPulse Smart Sauna, you can now enjoy the benefits of hot and cold therapy in one place. Explore below the individual benefits of each therapy and the synergistic effects when used together.

Word of Caution:

It’s essential to exercise caution when engaging in the hot sauna and cold plunge experience. Notably, this regimen may not be suitable for everyone. Individuals with a history of high blood pressure, for instance, should avoid it due to the potential shock to their system caused by the extreme temperature change. Pregnant women should also approach it with care. Experts advise taking only brief plunges into the cold water, as prolonged exposure can deplete the body’s heat and have adverse effects. As with any health-related activity, it’s advisable to consult a physician, especially if there are underlying health concerns.
