Magnetic Underlays for Joint Pain: Do They Really Work at Night
A magnetic underlay is a specially designed mattress topper embedded with strategically placed therapeutic magnets. Unlike a standard underlay that simply adds cushioning, this one is intended to promote better blood flow and reduce inflammation through static magnetic fields. When you lie down on it, these magnets interact with your body’s natural electromagnetic field. The theory? Better circulation + reduced inflammation = less pain, better sleep.
