Inducing jet lag in an older person: directional asymmetry.
An 85-year-old woman experienced simulated jet-lag in phase advance and phase delay directions, in laboratory simulations (in temporal isolation) involving 6-h changes in routine. Circadian rhythm amplitude and sleep efficiency were less disrupted in the delay than in the advance condition, in contrast to circadian rhythm timing (phase), which appeared to show more rapid adjustment in the advance condition than in the delay condition.
