A chronomic (time-structural) view of the temporal disparity between the reduction in SIDS incidence and the prone sleeping prevalence is taken by examining whether the presence of a putative circadecadal cycle characterizes SIDS. If so, it may modulate a decrease in SIDS incidence preceding the initiation of "Back to Sleep" campaigns in Styria, Austria, and elsewhere. An infra-annual cycle in SIDS, with a frequency lower than 1 cycle per year, may deserve exploration in the context of accumulating circadecadal cycles previously dismissed as unpredictable secularity. Biospheric circadecadals are now being recognized as tentative associations with physical environmental cycles, probably anchored in the gene pool of organisms in the evolutionary past. Circadecadals may continue to resonate with current environmental rhythms of corresponding frequency, with phase response curves brought about by feedsidewards, insofar as may be inferred from circadian and circaseptan precedents.
