> Some emerging research suggests Earth’s magnetism matters, as well. Being barefoot on the ground versus 30 stories high in a downtown skyscraper puts you in a completely different magnetic environment.

Really? My instinctive reaction to this statement is that it's quackery. Would be very interested to see headlines appear about this if it's true.

You can write pretty much anything you want after “Some emerging research suggests”

And Earth's magnetic field is extremely weak

More evidence this may have been written by a pigeon...

People already live in different altitudes, ie with vastly different amounts of rock between themselves and the bits of the earth that produce her magnetic field.

So colour me skeptical of this claim as well.

And while I like going barefoot for other reasons, I don't think it makes much of a difference to the magnetic fields.

There might be precedent for being able to detect changes in magnetic field
