abstract="Infradian components, with a frequency lower than 1 cycle in 28 hours, in the time structures (chronomes) of several physiologic variables are recorded in a woman isolated from society for 103 days in a cave. The physiologic time series rendered equidistant by editing reveal a phase-modulated 73-hour periodicity over much of the isolation span in the inter-micturition interval and in the urinary water excretion rate. The caffeine metabolite ratio also reveals a circasemiseptan. Rather than interpreting this circasemiseptan free-run as purely endogenous, a coherence with cosmic ray disturbance at a trial period not differentiated from precisely 84 hours is noted from cross-spectral analyses. Later suicide, depression in 2 earlier isolation cases, and earlier associations of ward behavior with cosmic rays add both a biophysical and a psychiatric context to these findings.<p /><p>Language: en</p>",
