Don’t worry, Herschel far infrared heaters are completely safe.
Herschel far infrared heating is 100% natural for our bodies and our well-being. The human body is designed to accept and emit infrared waves.
Far Infrared heating works on the basis of gentle, long-wave Infrared which penetrates the air and heats solids. If you like the warmth of the sun then you will love the feeling you get from your new infrared heating system. However, unlike the sun our heaters only emit safe infrared heat, not the harmful UV. So, you get the feeling of the sun without the damaging rays (and minus the suntan unfortunately!).
