Self-experimentation concerns not only scientists, but also each individual for the sake of
his/her chronobiologic health and science literacy, eventually to be acquired in primary and …

Environmental effects on human physiopathology are revisited herein from a chronobiologic

Geomagnetic variations of partly interplanetary origin, with cyclic signatures in human affairs
and pathology include the incidence of various diseases, regarding which this study of …

Effects of geomagnetic disturbance on heart rate variability (HRV), the 1/f fractal scaling in
