What is recommended for short duration travel of less than 48 hours regarding circadian rhythms?

For short duration travel of less than 48 hours, adaptation of circadian rhythms is generally not necessary because the body can manage temporary shifts in sleep-wake patterns without significant disruption. This applies particularly to travel across one or two time zones where the duration of exposure to the new time zone is relatively brief. The risk of experiencing severe jet lag symptoms is lower, allowing individuals to maintain their performance and alertness without undergoing a full adaptation process.

In scenarios where travel is limited to such a short time frame, individuals can typically rely on their existing routines and acclimatize to minor changes more comfortably. Addressing sleep schedules more drastically may not yield significant benefits and could, in fact, lead to unnecessary complications if the stay is brief. This is why other options that imply a need for complete adaptation or changes to sleep schedules do not align with the recommendations for short-duration travel.
