German researchers studied human circadian rhythms by isolating subjects in an underground bunker, exposing them to constant conditions or artificial light-dark cycles. They found that natural body clocks could become desynchronized from each other and from external cues, with temperature rhythms taking several days longer to readjust than activity patterns when light schedules shifted.
