<p>As usual, your provocation lead me to speculate and google and
speculate some more. <br>
</p>
<ol>
<li>Is sleeping E/W significantly different and N/S
geomagnetically? (I prefer to be woken by the rising sun,
myself, not so clear on the geomagnetic implications though)<br>
</li>
<li>Does the off-vertical angle of the earth's field (at
mid-latitudes -N/+S) effect humans, esp. when traveling/moving
between mid/extreme/equatorial latitudes? (Might yield
something akin to a latitudinal version of jet-lag?)<br>
</li>
<li>Does wearing a tinfoil hat *in* an electromagnetic field
introduce fields larger than the geomagnetic field?</li>
<li>Does 3) above qualify for (accidental?) self-medication for
mental disorders?

<li>does Randall Munroe (XKCD) read my mind?

<pre class="moz-quote-pre" wrap="">After a downwards magnetic field rotated counterclockwise, some people responded with a large drop in amplitude of their EEG alpha waves, up to a 60% decrease from pre-stimulus levels. Alpha waves are EEG oscillations that go up and down at a frequency around 10 Hz (10 times per second). They dominate the EEG signal when we are awake with our eyes closed, and arise from the spontaneous, synchronized activity of millions of neurons. Their function is not well-understood, but they may reflect a relaxed mind with nothing in particular to focus on and no particular task to do. When a stimulus suddenly appears and is processed, neurons fall out of synchrony with each other, the alpha rhythm is disrupted, and alpha waves get smaller as a result.
