From Polyphasic Sleep Wiki
In a similar vein to flexing, a schedule may be destabilized due to sleep time changes. Examples include the time shift that occurs as a result of Daylight Savings Time, time zone changes as a result of travel, or changing sleep times without a proper flexing adaptation first. These shifts can cause a desynchronization between a sleeper's circadian rhythm and their schedule, which cause similar changes to sleep quality that flexing may have, but often on a greater scale. The farther one shifts a sleep, and the more sleeps they shift at once, the higher their chances of schedule destabilization are.
