I have a 7 year old Sunlighten Impulse 2 person infrared sauna. When you body has an infection you get a fever and your body will burn out tge infection by raising your body temperature. An infrared sauna will mimic this.This sauna has Far, Mid, and Near infrared. It also has a 7 inch tablet with wifi abilities and Blaupunkt speakers and Chromotherapy ( red light, or any other light color you want ). I have a video of it with the radio turned up and the lights on, if you want to see the video please text me. This sauna will reach a maximum of about 140 degrees that you can sit in for long periods of time, because of the ability to sit in this infrared sauna longer it makes this a better choice than steam saunas. The only reason I am selling this is we are moving out of the country soon and all my household goods are going. Pick up only.
