While we understand the appeal of combining sauna time with Vital Red Light therapy, we recommend you don't use your Vital device in a sauna for your safety. As our devices require a lot of power, they may get very hot while in use—and the hot temperatures may pose an electrical safety risk.    However, we must note that using your Vital light before or after your sauna session can be very beneficial. Red lights and saunas complement each other exceptionally well. As saunas deliver energy in different near infrared vs far infrared wavelengths, there is no effective overlap between the two therapies.
