That’s cool. What is the difference between an infrared and just like the regular sauna? I’ve heard some negative things about the infrared one, but I’ve never really looked deeply into it. 
Infrared doesn't get as hot. The barrel saunas can get up over 160-180 fairly easily. If you don't live in a sunny area infrared is definitely helpful
