Jet lag is a well-documented phenomenon that occurs when individuals travel across multiple time zones, leading to a misalignment between their internal circadian clock and the local time at their destination. This misalignment can result in a variety of symptoms, including sleep disturbances, cognitive impairments, mood changes, and gastrointestinal issues.

Jet lag is a real and recognized condition resulting from the rapid crossing of multiple time zones, leading to a temporary misalignment between the internal circadian clock and the local time. This misalignment causes a range of symptoms, including sleep disturbances, cognitive impairments, mood changes, and gastrointestinal issues. The severity of these symptoms depends on various factors, including the number of time zones crossed and the direction of travel. Effective mitigation strategies, such as light exposure and melatonin administration, can help alleviate the symptoms of jet lag.
