As a wellness-obsessed beauty editor, I pride myself on knowing all about the latest and greatest tech gadgets before they make it big. I have a stellar track record too. I was an early adopter of microcurrent devices, LED masks, state-of-the-art shower and sink filters, vibration plates, and more. Still, I’m not perfect, and sometimes, a new device or technology will hit my radar after it’s already relevant and recognizable. That was the case with PEMF mats.

I learned about them from my friend and fellow beauty editor Shawna Hudson. PEMF stands for “pulsed electromagnetic field.” Proponents say it offers all kinds of benefits, including streamlined stress reduction, better sleep, faster muscle recovery, and more energy. It sounded good—almost too good. How could plugging one of these PEMF mats into a wall and lying on it for a few minutes improve so many lifestyle markers? I’m a natural skeptic, so I knew I wouldn’t be sold on this new wellness modality until I could try it out for myself.
