What is the recommended limitation for shifting time zones?

The recommended limitation for shifting time zones is typically about 1 hour. This guideline is based on the understanding that our bodies have a natural circadian rhythm that is closely tied to the time of day. Shifting by 1 hour allows for a more gradual adjustment, making it easier for individuals to acclimate to their new environment without experiencing significant disruption to their sleep patterns and overall well-being.

Traveling across time zones can lead to jet lag, which occurs when the body's internal clock is out of sync with the new local time. A change of 1 hour minimizes the impact of this disruption, whereas larger shifts, such as 2, 3, or 4 hours, can lead to increased difficulty in adjusting, more severe jet lag symptoms, and strain on both physical and mental health. Therefore, limiting time zone changes to 1 hour is a practical approach for promoting better adaptation.
