Wellness, not treatment
PEMF is a small, badly documented corner of consumer wellness hardware with wide price gaps and wilder marketing. This desk does the boring work: what the physics is, which claims have peer-reviewed support, which clearances exist and for what, and how mats, coils and wearables compare on intensity, frequency and price per year of use.
Desk stats
PEMF devices pass pulsed electromagnetic fields through tissue. Here is what the mechanism plausibly does, what parameters describe a device, and where the marketing runs ahead of evidence.
A practical pre-purchase checklist for consumer PEMF hardware — form factor, specs that matter, safety red flags, and cost per year of use.
A plain-language survey of where PEMF research is strongest (narrow clinical indications) and where consumer wellness claims outrun the data. With the caveats that matter.
