PEMF: what the research says

Some evidence it may ease long-lasting low back pain. It did not lift mood in a careful trial; other wellbeing uses are not studied.

What a session is

You lie on a mat or rest a pad on your body while a device creates a gently pulsing magnetic field. Most people feel little or nothing.

What the research says

• Back, neck and muscle tension: A review of 14 small studies found less long-lasting low back pain, but no better movement. Studies of shoulder pain found no benefit. Some evidence it may help · NCCIH, 2023 · Clinical Rehabilitation, 2022
• Low mood: For depression that medicines had not helped, a careful trial found it no better than a dummy device. One earlier trial found a benefit. Limited evidence · Journal of Affective Disorders, 2021
• Sleep, stress, anxiety, menopause and grief: Not studied in the sources we use. No good evidence yet · NCCIH, 2021

Is it safe?

It appears safe for most people. Magnets can interfere with pacemakers and other implanted devices. If you are expecting a baby or have a health condition, check with your doctor first. NCCIH, 2023
