[LINK] Electromagnetic Hyper Sensitivity

[Jim Birch]

As I see it, these effects, if they exist at all, are pretty small.  There
have been numerous epidemiological studies of mobile phone use including
some with good design and high numbers.  None have found anything more than
what looks like noise and, importantly, no one has found a dose-related
link between health outcomes and mobile use time.  In comparison, a
dose-related relationships can be found between health and alcohol
consumption, exercise, time viewing tv, and so on.  This doesn't eliminate
a possible health effect is just makes it very small. If you're worried
about mobile phone usage, you'd be better off to stop worrying and walk up
two flights of stairs every day.

As for feeling the effect of phone use, eg, feeling light headed after
calls, there could be numerous other explanations for what is felt.  The
effect of changes in posture and breathing would be the first things I
would check out as this is a known effect.  There was a study done a few
years back where gizmos with phone-like emf emissions were strapped to
people's heads and IIRC double blind testing found that people could not
tell if the device was off or on, nor did effects show up in standard
psychological tests.  Again, this doesn't disprove the effect but it does
place limits on it.  It would be really interesting to put some EHS
sufferers through a double blind test. People believe anything, especially
scarey anything, and beliefs have physiological effects.  Transcranial
electrical and magnetic stimulation are known effects - though these use
more energy and aren't at the frequencies of mobile phones.  These are
interesting for their positive effects though there are some low frequency
risks, including: feeling faint.
