PEMF stands for Pulsed Electromagnetic Field. Devices that utilize PEMF technology emit electromagnetic waves at different frequencies in order to stimulate and encourage your body’s natural recovery process. You’re probably wondering how PEMF technology can benefit your body when other electromagnetic fields – like those produced by microwaves and x-ray machines – are harmful. According to Bulletproof, “frequency and duration make all the difference.” The waves created by PEMF devices occur in brief bursts and are very low-frequency, like the electromagnetic waves found in nature. In fact, most waves involved in PEMF treatments have a lower frequency than you would be exposed to during a thunderstorm.
