Abstract

The blood pressure (BP) and heart rate (HR) of 32 newborns were measured around the clack at about 15-minute intervals for 5 to 20 days to examine any association of their time structure with changes in the local geomagnetic disturbance index (Moscow K) during the exact monitoring span of each baby. Cross-spectral coherence between the geophysical and physiological data series showed associations in the infradian and ultradian domains. Nonlinear least squares analysis of circaseptan components, determined with a trial period of 168 hours (1 week), previously shown to be prominent in early extrauterine life, showed a positive association of the period between local K and neonatal BP and a negative correlation of the amplitude between local K and neonatal HR.
