What concept describes the disruption caused by fluctuating bedtimes, compared to moving across time zones?
Answer
Social jetlag
When an individual's schedule causes their bedtime to fluctuate significantly from one day to the next—for instance, going to bed at 10:30 p.m. one night and 1:00 a.m. the next—the resulting disruption to the internal timing signals is frequently referred to as social jetlag. This term highlights the similarity between the body’s confusion caused by irregular internal timing and the disorientation experienced when physically moving across multiple time zones. This inconsistency hinders the body's ability to anticipate sleep signals, making it harder to initiate and maintain sleep when attempting to adhere to a more structured schedule.
