Temporal associations of life with solar and geophysical activity

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