Signatures of space weather in the aging human blood circulation?

The signature of an environmental decadal or longer cosmic cycle is found in each of 4 men's circulation. The assortment of pairs of environmental and physiological periods, τs, can differ among some variables and even for some of the two circadian rhythm characteristics of the same variable in the circulation of the same subject. As gauged by overlapping CIs (95% confidence intervals) of the τs in us and around us, the environmental pairing (e.g., of two subjects' diastolic blood pressure) can thus differ for the MESOR, M, a midline-estimating statistic of rhythm versus the circadian double amplitude, 2A, a measure of the extent of within-day change. A change in period length with the lengthening of a time series and/or advancing age is also recorded in the para- annual, para-decadal and para-tridecadal range of the spectrum. To whatever extent these findings can be extended to the population at large, the imaginary baselines reported in investigations involving interventions in aging will be amenable to replacement by cycles here demonstrated longitudinally, yet to be mapped on a population basis.
