text: what affect does the earth magnetic field have on the direction we sleep? im interested to see if anyone has any comments to make on this? does it have any affect on our sleep patterns or any other factors? i know i sleep better with my head facing either north or south.    the only time it didn't matter was when i was in the navy sleeping on board the ship, but the steel ship kept compasses from working, so i imagine it sheilded me from the earth's magnetic field enough...  of course i needed to slept in line with the keel when i was on ship...  i don't know of any scientific evidence one way or another...
