How often should I use the blanket? Is there a difference between MiHIGH and a regular Infrared Sauna? Do I get the same effect with my face being out of the blanket? I’ll sweat in the blanket.. so how do I clean it? Is the blanket low EMF? What comes with MiHIGH blanket purchase? What’s a MiHIGH blanket made from? How does the blanket charge/run? How long does the blanket take to heat up? How do I adjust the blanket temperature? What is the risk-free trial? What is the warranty? Do you ship globally?
