Infrared heat is band of energy that operates between 5.6-15 microns. Infrared heat is naturally occurring and is perfectly safe. Think of it this way. You’re sitting outside having a picnic on a sunny day. You feel nice and warm. But when a cloud passes over the sun, the air temperature doesn’t change, but you feel cooler.
Infrared saunas DO NOT emit UV rays or microwaves. They only emit infrared heat. This heat penetrates 2-3 inches into your issue relaxing and regenerating it. In fact, many hospital nursery incubators use infrared heat to warm their babies.
Infrared heat is the same heat you feel from the sun…but WITHOUT the harmful UV rays!
