Why Jet Lag Affects Travelers

Jet lag remains a pervasive issue for international travelers, affecting their health and well-being. This condition, characterized by sleep disturbances and fatigue, is caused by the body's circadian rhythm being out of sync with the local time zone. As travelers cross multiple time zones, their internal biological clock struggles to adjust quickly, leading to a misalignment with the external environment.

Experts suggest that this disruption can have various physiological effects, including impaired cognitive function and mood swings. Researchers from prominent institutions, such as the National Institutes of Health, emphasize that understanding one's exposure to natural light and adjusting sleep schedules prior to departure can help alleviate the symptoms of jet lag. While no universal cure exists, adopting strategies such as staying hydrated, avoiding alcohol and caffeine, and planning rest periods during travel can significantly diminish the effects of jet lag.

As international travel resumes its momentum, addressing this health concern continues to be of paramount importance.
