> One slightly leftfield possibility is that keeping magnetic fields in symmetry about the axis of your body could affect certain bodily processes. There are tantalising bits of evidence to back this up – in humans, the time it takes to drift into REM sleep and the electrical activity in the brain differs depending on whether we’re facing a north-south direction or an east-west one. I hadn't heard about this before but this sounds interesting. I wonder much of an effect it has on sleep.
