Iron is an important ingredient in
human blood. Earth is engineered because of
the powerful magnetic forces on the planet.
When the head is aligned to the north
and stays that way for few hours, the magnetic
pull exerts pressure on the brain and
immediately the pulse rate drops. If the
blood vessels are weak, one could have
hemorrhages and paralytic strokes. It also
makes a person agitated because there is more
circulation in the brain than there should be when sleeping. So, the best direction to sleep
with head pointing towards is East Northeast is okay. West is alright. South, if you
must.
