| In biology, circadian rhythms with a period
of one cycle in 20–28 h are known to be ubiquitous and partly endogenous.
Rhythms with a frequency lower than one cycle per day are called 'infradian
rhythms'. Among them are components with one cycle in about 3.5, 7, 14 and 28
days, the multiseptans, which, like the circadians, must be regarded as a
general characteristic of life: they characterize unicells as well as much more
differentiated organisms. We hypothesize that heliogeophysical factors other
than the solar visible light, held responsible for the evolution of circadian
periodicity, underlie the infradian rhythms of biosystems. The periodicities in
the solar wind and variations in the interplanetary magnetic field (IMF) which
are associated with the solar rotation are very similar in length to the
biological periodicities. We investigate the temporal relations of variations in
solar activity and in biological systems to test associations between events in
the IMF, in geomagnetic disturbance, in myocardial infarction and in physiology.
By cross-spectral analysis, we also find relations at certain frequencies
between changes in human physiology on the one hand, and (1) the vertical
component of the induction vector of the IMF, Bz, and (2) a
global index of geomagnetic disturbance, Kp, on the other hand. We wish
to stimulate interest in these periodicities of both biological systems and
geophysical endpoints among physicists and biologists alike, so that problems
relevant to clinicians and other biologists, including evolutionists, are
eventually solved by their cooperation with the geophysical community. |
