Hi. Thank you for your enquiry.
Our BFST devices work by emitting Electo-Magnetic Energy. This energy is well below the visible light frequencies which is well within the safe zone. It is far above the highly magnetic frequencies and also at very low intensities, relative to therapies like Short Wave. Our technology is superior to shortwave, ultrasound, microwave and IR LED.
I hope this information helps. If you have any further questions or concerns, please do not hesitate to contact us.

Kind regards,
