The earliest ancestor of today's biorythms seems to be invented
by a contemporary of Freud (sorry, I forgot his name), who had
only two cycles (28 days feminine, 23 days (I think) masculine)
that he claimed were active in everybody.  Freud championed his
cause.  I don't know when or why the third cycle was introduced.
The 28-day cycle for women (only) has a clear foundation, but
the more general claims do seem to be in the same category as
astrology.  The similarities between the two are striking.
