Well, I have only used my new sauna blanket. Once, I must say it aided and relaxation as I quickly fell asleep and took a 30 minute nap, which is something I have trouble doing.
Was told to start at 120 didn’t feel much 140 not much 160 did it. So I can’t image what 179 will do. My bottom half was drenched not so much the top but it was great.
