Pulsed Electromagnetic Field (PEMF) therapy utilizes low-frequency energy waves to influence cellular activity and promote healing for a variety of conditions. Research indicates that this non-invasive technology can significantly improve insomnia disorder by reducing symptoms and enhancing overall sleep quality through neural regulation. Beyond sleep, the therapy is used to address mitochondrial dysfunction, potentially boosting cellular energy production and accelerating tissue repair. It has gained regulatory recognition for treating non-union fractures and treatment-resistant depression, although some medical claims remain subject to ongoing clinical debate.
