Outdoor Infrared Sauna Benefits:

  • Relaxation
  • Improved circulation
  • Sore muscle relief
  • Improved sleep
  • Detoxification

Infrared heat is much more gentle than hot rock or steam saunas. Traditional saunas can create heat and steam in excess of 200°F, but infrared heat operates at the much more comfortable temperature of 100°-150°F while providing all the benefits you would expect from a steam sauna. There is also evidence that infrared saunas can boost collagen production and improve your mood.
