  • Disruption to Biological Rhythms
    • Jetlag
      • Caused by travelling across time zones so quickly that biological rhythms do not match external cues, causing sleepiness in the day and restlessness at night.
      • West- East= Phase Advance
      • East- West= Phase Delay (easier for body to cope with)
    • Shiftwork
      • Can involve working at times when normally asleep and therefore being asleep at times normally awake. Causes breakdowns in the usual coordination between internal biological clocks and external cues.
      • Can affect- alertness, sleep deprivation, health, mistakes
