EARTH'S
MAGNETIC
POLE
FLIP
& BIOLOGICAL
EVENTS:
IS
THE
FLIP
RELATED
TO
EARTH'S
BIOLOGICAL
DEMISE?
Hans
Selye's
neuroimmune
biology
work
lends
explanation
to
weather-related
physiological
changes:
the
hypothalamus
stimulates the pituitary to
produce
ACTH; the adrenal glands then
produce corticosteroids to
cope
with
stress.
Despite the
bees'and
doves' well-known
magnetic
sensation, effects
of
magnetic
fields on our
bodies are subtle
and complex. As
the
deep sea
environment
is
virtually free from
magnetic field influences, studies
had begun in
the
1950's: other
than
mental and
emotional
effects,
changes
of
blood
pressure, pulse and
white
blood
cell counts
had occurred. With
the increased
blood
cellcounts,
viscosity also increases,
and
clots
may
form
in
veins.
While
magnetic
jitters
last
just
a
few
days, flipping
of
Earth's magnetic
poles occurred every
half
a
mil-
lion
years
or
so,
affecting life on
Earth. As
the
last
flip
had
oc-
curred
as
long as 730,000
years
ago,
the
Earth's magnetic
field
is
already documented
to
be
de-
creasing steadily. With
the
weak-
ening magnetic field and our
habit
of living inside buildings shielded
by concrete,
it
pays
to
develop
gadgets to supplement
the
loss
of magnetic field strength.
