"The immune system boost" seems paradoxical but there are a number of
situations where adjusting the immune response generates a favourable
outcome. In relation to psychiatry and neurodegeneration, any so called
"suppressive" effect seems better. What needs to be suppressed are the
inflammatory mediators like il-1, tnfa, il-6, il-12, some chemokines
etc. What needs to be raised is tgf beta, il-4, il-10. The latter
allows for a more pronounced adaptive response (I think). So boosting
the immune response may mean a change in immune function.
A fascinating example of this is seen in depression, often associated
with excessive right side activation, which is often associated with an
increased inflammatory response. With Insight Meditation individuals
can improve their mood and this correlates with a reduction in right
and increase in left side activation, which also leads to an improved
immune response despite the drop in inflammatory mediators.
PS: Forget about the self non-self model of immunology. It is
misleading and should not be taught. Within the research community at
least, "The Danger Model" is the accepted paradigm.
A few years myself and my former collaborator did some digging around
on EMFs. We came to a similiar conclusion to yourself: something very
interesting going here, more research is needed but clearly there are
potential benefits and risks in relation to EMFs. It may simply be the
case that a little irritation induces a protective response. Eg. Cell
priming: a slight stress primes the cell to cope with a latter larger
stress. There was even a research report claiming a little radiation is
a good thing because it stimulates things like Ku70, a DNA repair
For an excellent overview of neuro - immune -endocrine interactions
look at Sapolsky et al. I
