You guys need to be careful about prolonged exposure to Tesla coils.

That paper is about *ultrasound*, not RF or electromagnetic fields.
And at a fairly high exposure: >1 Watt/cm2 (for comparison, a typical
RF exposure limit is a few milliwatts/cm2)
At that sort of power density, one would want to look for thermal
effects, since you could definitely feel that flux. (to compare,
sunlight is about 0.1 Watt/cm2...) With that level of power deposition,
vasodilation as a response to tissue heating is probably not unexpected.
(just going from the abstract.. I haven't read the full paper)
Tesla coils (and particularly plasma globes) operate in a frequency range
that causes the arteries to dilate.
I don't think so. At least not on the paper you cite.
Consider, for instance that just about every switching power supply in
the world these days operates between 25-100kHz and has some radiated E
or H field.
If you feel pronounced improvement in
your overall well being during the operation of a coil, then that may not
be such a good thing. It may be that your arteries are partially clogged
and blood flow is temporarily improving.
Prolonged exposure to 29 kHz E field radiation, such as having a plasma
globe in constant operation, will cause vasodilation and improve your
circulation, but when you leave the 29 kHz E field the arteries will
contract to their normal state. In advanced atherosclerosis, this could
cause panic attacks about 30 minutes after the field is turned off.
Before making such a claim, I'd like to see some published studies. I'm
pretty familiar with most of the literature about EM exposure and RF
safety (ANSI IEEE C95.1-2005 has a very complete list, and dozens of
pages summarizing that literature), and I don't recall seeing anything.
Since C95.1 is available to be downloaded free
http://standards.ieee.org/findstds/standard/C95.1-2005.html
I don't have C95.1 memorized, so maybe I've overlooked something.
Perhaps you could find something in there to backup your assertion of
vasodilation (from other than thermal effects, since a fairly simple
calculation shows that the power absorption from the fields from a tesla
coil or plasma globe is quite low)
If it's not in there, (maybe more recent research than early 2000s?)
please provide a citation.
