Inducing jet lag in older people: adjusting to a 6-hour phase advance in routine
TH Monk, DJ Buysse, CF Reynolds III… - Experimental gerontology, 1993 - Elsevier
A 15-day simulated jet lag experiment was performed in a time isolation laboratory using 15
old women (79–91 years, mean 82.9 years) and 10 old men (71–86 years, mean 80.5
years). After five full days and nights on the subject's habitual routine, the waketime of night
6 was advanced by 6 h, truncating the sleep episode. All subsequent events occurred 6 h
earlier than normal. Adjustment to the phase shift was evaluated by the circadian rhythm in
rectal temperature (measured every minute), polysomnography of each sleep episode, and …
