Health Benefits

Benefits of Infrared 

  • The technology of the Spectrum Plus incoloy heaters warms your core body temperature, producing a cleaner, healthier sweat while lowering blood pressure, and maintaining heart health.
  • The natural heat produced by the Spectrum Plus heaters is designed to achieve a more controlled hot climate much like a traditional sauna without the unbearable heat temperatures. This deeper penetration through sweating goes beyond the muscle and fat rather than a traditional or hot air sauna.  As a result, you’re able to work up the best possible sweat in the least amount of time.
  • Spectrum Plus heaters remove 17% more toxins such as cholesterol, fat-soluble toxins, toxic heavy metals, sulfuric acid, sodium, ammonia and uric acid.
  • Full Spectrum Sauna combination of long-wave Spectrum Carbon 360 infrared panels with UL-listed short-wave Spectrum Plus™ infrared panels. This combination provides higher temperatures, full body coverage, deeper penetration, and better experience than any other sauna.
  • Reap the benefits of a more natural pain relief remedy with every infrared sauna session.
  • Athletes can appreciate a faster muscle recovery with increased blood flow to the muscles, delivering more concentrated oxygen and creating more energy to heal.
