Abstract

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 secondary education. Public education ensures that everybody who knows how to read or write can dispense with the service of a costly scribe. At all ages, public education can teach equally well how to find out whether one's blood pressure (BP) and heart rate (HR) responds to an increase in sodium intake with a rise, with no change or with a decrease in BP. This task and many others could become a matter of informed self-surveillance. Whenever there are inter-individual, sometimes opposite differences in response, government-sponsored trials on groups that do not consider such differences cannot solve what only the individual can do, at first by help from schools. Eventually special institutions may be designed for chronomics, the monitoring, interpretation and archivization of chronomes (time structures; from chronos = time and nomos = rule) of biological variables, also charged with a demographic analyzing and reporting system. Each individual's properly coded record, to guard confidentiality, becomes part of a promptly accessible database for one's own needs and for society's requirements. What individuals and small groups started as chronobiology, what is immediately available on back burners, as a service by an international project on the biosphere and the cosmos (BIOCOS) (corne001@umn.edu) could become a public system of planned surveillance archivization of one's rhythms from womb to tomb. Alterations of a rhythm's amplitude or acrophase or of a deterministic or other chaotic endpoint, such as a correlation dimension and approximate entropy, or of a standard deviation, among a multitude of other endpoints, can signal (in the otherwise neglected normal range) reversible risk elevations. If these elevated risks are detected and prompt the institution of countermeasures, such prehabilitation can save the cost of rehabilitation or of long-term care after morbid events; suffering also can be prevented such as that by those who are unlucky enough to helplessly survive a massive brain, heart or societal "stroke". As an equally important dividend, science gains in basic and applied terms, as illustrated herein by the demonstration of a trans-year, an approximately 1.3 to 1.6-year, heretofore unknown component of the human BP and HR spectrum, beating with the circannual component and characterizing the same data. Chronomically interpreted self-monitoring is a civic duty for both one's health and everybody's science.
