Do I Really Need A Full Spectrum Sauna? (near infrared VS far infrared)

My opinion on full spectrum saunas for detox, and near infrared vs far infrared based on my own experiences. I might use the wrong terminology, or not get some of the scientific facts straight (I'm still learning), but after testing 9 saunas and building two, this has been my personal experience using far infrared, full spectrum, and "near" infrared saunas. https://youtu.be/OFIdkC6n7Cw
