there are an awesome number of variables involved in the actual, measurable effects having to do with this. there has been too much denial, and false skepticism, so these effects have not, to my knowledge, been properly catalogued, let alone sufficiently studied. MR has been, as far as I understand, been related to difficulties in communication, and realization of planning. I find that it is a time of explosive creativity for me, as long as, I don't try to involve anyone else, or act on the results of the brain hurricane until the MR is over.

there are, at least, gravitational, magnetic, electromagnetic, as well as scalar interaction. this is not to mention the sun, other planets, galactictic, and cosmic radiation, gamma ray bursts, and much, much more. there are an amazing number of energetic inputs to the earth system. I've spent much time trying to understand this and my mind still boggles at the scale and complexity.
